Description

  The present invention relates to an automatic pattern matching apparatus that enables cutting so that patterns between constituent parts of a patterned product match each other, and an automatic pattern matching program that is installed and used in a computer of the apparatus.

  The manufacturing process of the cloth product includes a cutting process in which the dough is stretched over a cutting machine and each component part constituting the cloth product is cut into a predetermined size and shape. FIG. 23 is a diagram illustrating an example of a state in which the constituent parts 220 are arranged on the fabric 210 prior to the cutting process. Some slack and wrinkles occur on the fabric stretched by the cutter. When the fabric product is plain, it is not necessary to consider the continuity or uniformity of the pattern between the component parts. For this reason, even if sagging or wrinkles occur in the fabric, it may be cut based on predetermined cutting data.

  However, in the case where the fabric product is a patterned product, the continuity or uniformity of the pattern is lost between the constituent parts if a fabric with slack is cut out based on predetermined cutting data. For example, as shown in FIG. 24, the continuity of the handle between the component part 231 and the component part 232 constituting the outerwear 230 and between the shoulder opening 234 that exposes the arm X and the component parts 231 and 232 There can be a situation where uniformity is lost.

  The value of goods such as clothes that do not have continuity or unity in the pattern must be low. For this reason, the apparel maker cuts out the component parts from the patterned fabric actually stretched by the cutting machine with a margin, and then cuts out the component parts manually so that the patterns match.

  On the other hand, various automatic pattern matching systems are also considered. For example, an image recognition apparatus disclosed in Patent Document 1 is known. This device can perform manual pattern matching with good operability when it is judged that pattern matching is impossible by an automatic pattern matching system for a fabric with a delicate pattern that makes it difficult to 100% automatic pattern matching. It is a thing.

JP-A-4-240261 (Claims, Abstract, etc.)

  However, the above method has the following problems. If you cut out larger parts, you will use more of the patterned fabric, which will increase the cost of the product. Finally, since each component part is manually cut, it is not possible to completely automate, and this also increases the cost of the product.

  On the other hand, in the case of the image recognition apparatus disclosed in Japanese Patent Laid-Open No. 4-240261, automatic pattern matching cannot be performed depending on the pattern, and manual pattern matching is inevitably required. For this reason, it is still impossible to fully automate the pattern matching of each component part. For this reason, the cost of goods will be raised.

  The present invention has been made in view of such problems, and an object of the present invention is to provide a high-quality patterned product at low cost by avoiding wasteful use of the patterned fabric and automating cutting.

For this reason, it is not necessary to store the absolute position information of each constituent part with respect to the handle, and only the relative position information between the constituent parts may be stored. Accordingly, it is not necessary to change the position information of each component part in accordance with the change from the theoretical matrix to the actual matrix.

  Another aspect of the present invention is an automatic pattern matching apparatus that arranges all the constituent parts so that the constituent part arranging means in the previous invention approaches the origin side in the longitudinal direction of the actual matrix.

  Next, an embodiment of an automatic pattern matching apparatus and an automatic pattern matching program according to the present invention will be described with reference to the drawings.

  FIG. 1 is a diagram showing an automatic pattern matching system.

  This automatic pattern matching system includes an automatic pattern matching device 1, a cutting machine control device 2, an imaging device control device 3, an automatic pattern matching device 1, a cutting machine control device 2, and an imaging device according to an embodiment of the present invention. A distributor 4 connected to the control device 3 and capable of transmitting and receiving data to each other; an imaging device 5; a distributor 6 connected to the imaging device control device 3 and the imaging device 5 and capable of transmitting and receiving data to and from each other; A cutting table (hereinafter simply referred to as “table”) 7 connected to the cutting machine control device 2 is provided.

  The automatic pattern matching device 1 receives a plurality of imaging data obtained by imaging the patterned fabric 8 stretched on the table 7 using a plurality of imaging devices 5, corrects the imaging data, and then acquires one imaging data. And display it. However, when there is only one received image data, no composition is performed. Moreover, the automatic pattern matching apparatus 1 produces a real matrix for arranging the constituent parts of the cloth product on the displayed patterned fabric 8 based on the operation of the operator. Thereafter, each component part is arranged on the actual matrix and converted into cutting data, and then the converted data is transmitted to the cutting machine control device 2. Each of these processes will be described later in detail.

  The cutting machine control device 2 is a device that cuts the patterned fabric 8 stretched on the table 7 while controlling it based on the conversion data transmitted from the automatic pattern matching device 1.

  The imaging device control device 3 is connected to a plurality of (in this embodiment, four) imaging devices 5 via a distributor 6, and turns on the shutter of the imaging device 5 in accordance with an operator instruction, 5 is an apparatus for receiving image data from 5.

  The imaging device 5 is a device that is fixed above the table 7 and photographs the patterned fabric 8. In this embodiment, a digital camera is used as the imaging device 5, but an imaging device other than a digital camera, for example, an analog camera, a video device, or the like may be used. Further, the number of the imaging devices 5 and the distance between the imaging device 5 and the table 7 can be arbitrarily set according to the size of the patterned fabric 8.

  The table 7 is a smooth table for extending the patterned fabric 8 to be cut, and is a place where the patterned fabric 8 is cut into each component by a cutter (not shown).

  FIG. 2 is a flowchart simply showing a schematic process of the process for cutting the patterned fabric 8 using the automatic pattern matching system shown in FIG.

  First, on the basis of an instruction from the operator, input of fabric information of the patterned fabric 8 (the fabric information includes pattern information) is performed (step S1). The fabric information includes the fabric width, fabric length, horizontal pattern start position, width direction pattern start position, and pattern-specific information (for example, if the pattern is a lattice pattern, each pattern in the horizontal and width directions of the pattern) Pitch), the shape and size of each constituent part, information on the position of each constituent part relative to the handle of the patterned fabric 8, and the like.

  Next, the patterned fabric 8 is photographed based on an instruction from the operator (step S2). The shutter of the imaging device 5 is performed by operating the imaging device control device 3. However, imaging may be performed by pressing the shutter of the imaging device 5 regardless of the operation of the imaging device control device 3.

  Next, lens distortion correction and ortho image creation processing are performed (step S3). In the lens distortion correction, each imaging data is corrected in consideration of the lens distortion of each imaging apparatus 5. The ortho image is created by removing the depth component of the image based on the shape correction data for each image pickup device 5 and correction basic data (calibration data) for synthesis.

  Next, the corrected imaging data is synthesized based on the calibration data (step S4).

  Next, the synthesized image is displayed, and an actual physical pattern (in this embodiment, since it is a lattice pattern, a physical pattern line) is produced on the synthesized image (step S5). Here, the physical pattern is synonymous with the “real matrix” mentioned above. At this time, an ideal pattern (in this embodiment, a pattern line) is displayed as a theoretical pattern prior to the production of the physical pattern. However, the display of the theoretical value pattern is not an essential process, and the theoretical value pattern may be hidden.

  Next, automatic placement of the component parts on the physical pattern is executed (step S6). This process is performed according to a pattern matching procedure registered in advance. The registration of the pattern matching procedure includes, for example, matching the patterned fabric 8 and the component parts (on the pattern line, in the middle of the pattern line and the pattern line, on the pattern line or in the middle, not at all), how to match the component parts and the component parts Registration (relative alignment, target alignment, rate alignment for the pattern, no alignment). The automatic placement is tried a plurality of times within a predetermined time. As a result, the arrangement pattern arranged so as to be closest to the origin side in the length direction of the actual matrix is selected.

  Next, based on the arrangement pattern of each selected component part, the position information of each component pattern is converted into data (this is referred to as NC data) for enabling cutting with a cutter. S7).

  Next, the patterned fabric 8 stretched on the table 7 is automatically cut based on the NC data (step S8).

  Details of each step shown in FIG. 2 will be described later.

  FIG. 3 is a diagram illustrating a hardware configuration in the automatic pattern matching apparatus 1.

  The automatic pattern matching apparatus 1 includes a central processing unit (CPU) 11, a masked read only memory (masked ROM) 12, a RAM (Random Access Memory) 13, and an EEPROM (Electrically Erasable and Programmable Read). Only Memory 14, Hard Disk Drive (HDD) 15, and interface (I / F) 16 are provided. The CPU 11, mask chrome 12, RAM 13, EEPROM 14, HDD 15, and I / F 16 are connected by a bus 17 that is a communication line so that data can be exchanged with each other.

  The CPU 11 is a part that controls various controls performed by the automatic pattern matching apparatus 1. In the present invention, the CPU 11 is an image data receiving unit that receives image data obtained by dividing each part of the patterned fabric 8 and capturing the image data. The CPU 11 corrects the received data and synthesizes all the imaged data after correction. The CPU 11 is also display processing means for displaying the combined image data on a display (not shown). The CPU 11 also has a designated reference point receiving means for receiving information on the designated reference point of the pattern in the imaging data of the patterned fabric 8, and a plurality of reference points in the imaging data of the patterned fabric 8 that match the information on the designated reference point of the pattern. A reference point searching means for searching for, a real matrix preparing means for preparing a real matrix for arranging each component part based on the reference point searched by the reference point searching means, and It also serves as component part arrangement means arranged in the matrix and component part arrangement data sending means for sending arrangement data of each component to the cutting device side. In the present embodiment, the designating reference point information of the pattern is image data of a region including the designated reference point designated by the operator. However, the information is not limited to image data, and may be information that can be collated with other reference points, for example, RGB data in a region including a designated reference point, or data of a specific pattern portion in the region.

  In this embodiment, as will be described later, after arranging one of the constituent parts as the constituent part arranging means, the CPU 11 specifies the position of the next constituent part based on the positional information of the one constituent part. Then, the next component part is arranged. Further, the CPU 11 arranges all the constituent parts as constituent part arranging means so as to be close to the origin in the length direction of the actual matrix.

  In addition, the CPU 11 also serves as a defective part receiving unit that receives designation of a part unfavorable for the arrangement of each constituent part in the patterned fabric 8, and when the part is designated, Based on the position information, each component is arranged so as to avoid that part.

  Further, the CPU 11 also serves as a reference point change receiving unit that receives a partial change of the reference point. When the CPU 11 receives the change, the CPU 11 regards the received new reference point as a designated reference point as a reference point search unit. Search for the reference point again. Furthermore, in that case, the CPU 11 creates a real matrix based on the new reference point as a real matrix production means.

  The CPU 11 reads the automatic pattern matching program of the present invention and executes each process defined by the program. Detailed functions of each means of the CPU 11 will be described later.

  The mask chrome 12 is a part for storing a program such as a control program for the CPU 11 that does not need to be normally rewritten and other data. The RAM 13 is a readable / writable storage part and has functions such as a memory for display data. The EEPROM 14 is an electrically rewritable storage part.

It is a storage means. The HDD 15 is also a part for storing an automatic pattern matching program of the present invention installed from the outside.

  The I / F 16 is a part that transmits or receives data to / from external devices of the automatic pattern matching apparatus 1 (distributor 4, keyboard attached to the automatic pattern matching apparatus 1, pointing device, etc.). The I / F 16 is, together with the CPU 11, a designated reference point receiving unit, a component part arrangement data sending unit, a defective portion receiving unit, or a reference point change receiving unit.

  FIG. 4 is a diagram illustrating a hardware configuration in the cutting machine control device 2.

  The cutting machine control device 2 includes a central processing unit (CPU) 21, a masked read only memory (masked ROM) 22, a RAM (Random Access Memory) 23, and an EEPROM (Electrically Erasable and Programmable Read). Only memory 24, hard disk drive (HDD) 25, and interface (I / F) 26 are provided. The CPU 21, the mask chrome 22, the RAM 23, the EEPROM 24, the HDD 25, and the I / F 26 are connected by a bus 27 that is a communication line so that data can be exchanged with each other.

The I / F 26 is a part that transmits or receives data to / from external devices of the cutting machine control device 2 (distributor 4, keyboard attached to the cutting machine control device 2, pointing device, etc.).

  The automatic pattern matching apparatus 1 is not a dedicated apparatus, but has the same hardware configuration as that of a general-purpose personal computer hardware. Various processes of the invention can be realized. The cutter control device 2 can also use a general-purpose personal computer.

  Next, an outline of automatic pattern matching processing performed by the automatic pattern matching system will be described.

  FIG. 5 is a diagram showing a part of each component part constituting the clothes.

  The structural parts 31 to 37 are required to have continuity or uniformity of patterns at specific positions. For example, when the pattern is a lattice pattern, it is required that the pattern is continuous without shifting at a specific portion of the constituent parts.

  As shown in FIG. 5, since the position A of the component part 32 (lower sleeve 32) and the position B of the component part 34 (mountain sleeve 34) are matched, the pattern must be continuous between the position A and the position B. Similarly, the position C of the component part 33 (the front part 33) and the position D of the mountain sleeve 34, the position E of the front part 33 and the position F of the part 35 (waist cover 35), the component part 36 (rear) The pattern must be continuous between the position G of the body 36) and the position H of the waist cover 35, at the position I of the component part 37 (front collar 37) and at the position J of the back body 36.

  FIG. 6 is produced based on a component 41 (6A) arranged on an ideal (theoretical) handle 40 (referred to as “theoretical handle 40”) and a patterned fabric 8 actually stretched on the table 7. It is a figure which shows the structural part 51 (6B) arrange | positioned at the pattern (it is called "physical pattern 50") made.

  As shown by the dotted line in FIG. 6 (6B), when the component part 41 is arranged on the physical pattern 50 in its absolute position, when the component part 41 is cut, a predetermined position K of the component part 41 on the theoretical pattern 40 is obtained. , L pattern is not the same as the pattern at the predetermined position K, L of the component part 41 on the physical pattern 50. The physical pattern 50 is different from the theoretical pattern 40 because it is produced based on the actual patterned fabric 8 having wrinkles and sagging. Therefore, the constituent part 51 (shown by a solid line) must be arranged on the physical pattern 50 so as to be shifted from the constituent part 41 (shown by a dotted line). When the component part 51 corrected and arranged in this way is cut, the pattern part is close to the component part 41 on the theoretical pattern 40.

  FIG. 7 is a view for explaining a method of producing the physical pattern 70 based on the actual patterned fabric 60. FIG. 7 (7A) shows the actual patterned fabric 60, and FIG. 7 (7B) shows the physical pattern 70.

  As shown in FIG. 7 (7A), the actual patterned fabric 60 in this embodiment has a lattice pattern in which a vertical pattern line 61 and a horizontal pattern line 62 are orthogonal to each other. In order to produce the physical pattern 70, first, the operator determines the position of the designated reference point 64 in a state where the position of the origin 63 on the actual patterned fabric 60 that has been imaged is specified. Next, the operator stores the image data of the collation area 66 for searching each reference point in the HDD 15.

  The CPU 11 searches for the periphery 65 of the coordinate point based on the theoretical pattern 40, obtains a portion that matches the image of the verification region 66, and specifies the reference point. Of course, the operator can manually search each reference point one by one. However, if all the reference points are searched manually, it takes an enormous amount of time. Further, although it is possible for the CPU 11 to search for each reference point without using coordinate points based on the theoretical pattern 40, it still takes an enormous amount of time. For this reason, the CPU 11 searches for the vicinity of each coordinate point using the coordinate points based on the theoretical pattern 40, and the center of the portion having the pattern that matches the image of the region 66 for matching obtained at the designated reference point 64. Are used as reference points.

  When each reference point is determined in this way, the CPU 11 connects the reference points to produce a physical pattern 70 as shown in FIG. 7 (7B). The physical pattern 70 is composed of a vertical pattern line 71 and a horizontal pattern line 72. In this embodiment, the physical pattern 70 is a pattern approximate to the actual pattern fabric 60.

  FIG. 8 is a partially enlarged view of the state in which the synthesized image of the actual patterned fabric 60 displayed on the display (not shown) of the automatic pattern matching apparatus 1 and the physical pattern 70 are displayed in an overlapping manner.

  As shown in FIG. 8, the vertical pattern line 61 and the horizontal pattern line 62 of the actual patterned fabric 60 coincide with the vertical pattern line 71 and the horizontal pattern line 72 of the physical pattern 70. Is preferred. However, the search for the reference point may not be complete, and in this case, a slight shift may occur between the synthesized image of the actual patterned fabric 60 and the physical pattern 70. In such a case, it is also possible to correct a reference point that has been shifted by an operator's operation and newly perform an automatic search for each reference point.

  FIG. 9 is a diagram illustrating a state in which all the constituent parts 80 are arranged on the physical pattern 70.

  When the production of the physical pattern 70 is finished, a step of arranging each component part 80 on the physical pattern 70 is executed. This arrangement is tried a plurality of times on the assumption that the continuity or uniformity of the patterns between the constituent parts described with reference to FIG. As a result of the trial, an arrangement pattern in which all the constituent parts 80 are arranged so as to be closest to the origin side in the length direction of the actual matrix is adopted.

  Next, an example of processing executed by the automatic pattern matching device 1, the cutting machine control device 2, and the imaging device control device 3 and an example of a screen displayed on the display (not shown) of the automatic pattern matching device 1 will be described.

  FIG. 10 is a flowchart showing the flow of processing performed by the automatic pattern matching apparatus 1 based on the operation of the operator.

  When the operator inputs fabric information related to the patterned fabric 8 in advance from a keyboard (not shown) attached to the automatic pattern matching device 1, the I / F 16 of the automatic pattern matching device 1 receives the fabric information (step S101). Next, the CPU 11 of the automatic pattern matching apparatus 1 stores the fabric information in the HDD 15 (step S102).

  FIG. 11 is a flowchart showing a flow of processing performed by the imaging device control device 3 based on the operation of the operator.

  When the operator activates the image pickup device control device 3 and operates a keyboard (not shown) attached to the device 3 to instruct to photograph the patterned fabric 8, the CPU of the image pickup device control device 3 issues a command for instructing the image pickup. It transmits to the imaging device 5 and image | photographs the patterned fabric 8 (step S201). Next, the CPU of the imaging device control device 3 receives the imaged pattern fabric 8 data (imaging data) from the imaging device 5 and transmits it to the automatic pattern matching device 1 (step S202).

  FIG. 12 is a flowchart showing the flow of processing performed by the automatic pattern matching apparatus 1 based on the operation of the operator. FIG. 13 is a flowchart showing the flow of processing performed by the cutting machine control device 2 based on the operation of the operator after the processing shown in FIG. 14 to 21 are diagrams showing examples of screens displayed on the display (not shown) of the automatic pattern matching apparatus 1 during the processing shown in FIG.

  Subsequent to step S202 shown in FIG. 11, the I / F 16 of the automatic pattern matching apparatus 1 receives a plurality of imaging data (step S301). The CPU 11 of the automatic pattern matching device 1 stores a plurality of received image data in the HDD 15. Next, the CPU 11 corrects lens distortion and creates an ortho image (step S302). Next, the CPU 11 combines the corrected data based on the calibration data (step S303), and displays the combined image data on the display of the automatic pattern matching apparatus 1 (step S304). Step S304 may be a process performed automatically following step S303, or may be a process performed by an operator's operation.

  FIG. 14 is a diagram showing a screen 110 (including a composite image of the actual patterned fabric 60) displayed on the display of the automatic pattern matching apparatus 1 by the process of step S304.

  The screen 110 is a display area that displays a composite image of the actual patterned fabric 60 (in this embodiment, a lattice pattern image of the vertical pattern line 61 and the horizontal pattern line 62) in the approximate center. 111 and an area 112 that is displayed next to the display area 111 and collects various operation keys. In the area 112, a display area 113 for displaying a composite image of the actual patterned fabric 60 at a low magnification, a color selection instruction key 114, a line selection instruction key 115, an origin setting key 116, a scratch part instruction key 117, An image information key 118, an automatic search key 119, an arrangement start key 120, and a stop key 121 are arranged. These keys 114 to 121 have an icon form. A display field 122 for displaying a message to the operator is also arranged below the display area 111.

  In the display area 111, the display target can be enlarged or reduced by an operation of an accompanying pointing device (not shown). Even when the display target in the display area 111 is enlarged or reduced, the magnification displayed in the display area 113 is fixed to the first low magnification. The color selection instruction key 114 is a key for setting and changing the displayed origin, various pattern lines, and the color of the scratched part. The line selection instruction key 115 is a key for setting and changing the display line widths of various pattern lines and scratched parts. The origin setting key 116 is a key for setting the origin or changing the set origin.

  The scratch part instruction key 117 is a key for designating a scratch or the like displayed on the composite image of the actual patterned fabric 60. When the scratched part instruction key 117 is clicked with a pointing device, a scratched part setting dialog is displayed. Up to 10 scratch parts can be set. When the check box of the scratch part (1 to 10) is turned on, it becomes effective as a scratch part. The set number of scratched parts is not limited to 10, and may be less than 10 (for example, 5) or more than 10 (for example, 20).

  The image information key 118 is a key for displaying a dialog indicating information regarding image data being edited. Examples of the information include, for example, the image data file name, the number of dots, the resolution, the display speed, and the length, as well as the necessity of image change. The automatic search key 119 is a key for starting a search for each reference point. The arrangement start key 120 is a key for arranging the component parts 80 in a real matrix. A stop key 121 is a key for instructing to stop editing.

  When the operator clicks the origin setting key 116 following step S304 shown in FIG. 12, the CPU 11 of the automatic pattern matching apparatus 1 accepts this origin instruction command via the I / F 16 (step S305), and sets the origin. The position is enlarged and displayed on the display area 111 (step S306).

  FIG. 15 is a diagram showing a screen 110 displayed by the process of step S306.

  In the display area 111 of FIG. 15, the position of the origin at the lower left of the composite image of the actual patterned fabric 60 shown in FIG. 14 is displayed in an enlarged manner. The origin 131 exists at the center of the cross box 130. The origin 131 is the end of the actual matrix in the length direction, and exists on the cut end side of the patterned fabric 8. The measure 132 imaged when the patterned fabric 8 is imaged is also enlarged.

  When it is desired to change the origin 131, the operator clicks the origin 131 using a pointing device. Then, the CPU 11 accepts a click command and displays a pattern line matrix parameter setting dialog 140. The pattern line matrix parameter setting dialog 140 has a longitudinal direction start position box 141, a width direction start position box 142, a longitudinal direction pattern line interval box 143, a width direction pattern line interval box 144, an OK key 145, and a cancel key 146. Yes.

  When changing the origin 131, the operator changes the numerical values (units are centimeters) displayed in the longitudinal direction start position box 141 and the width direction start position box 142 by default. In addition to the origin 131, when changing the pattern interval, the operator uses the numerical values (unit: centimeters) displayed by default in the longitudinal direction pattern interval box 143 and the width direction pattern interval box 144. change. After the change, when the operator clicks the OK key 145, the input origin coordinates or pattern line interval is determined. On the other hand, when the cancel key 146 is clicked, no change is made. Note that a check box for instructing “Do not change matrix” may be provided in the pattern line matrix parameter setting dialog 140. When this check box is checked, only the position of the origin 131 is changed, and the pattern line is not changed.

  Returning to FIG. 12, when the operator designates the verification area 66 and clicks the automatic search key 119, the CPU 11 accepts the automatic search command via the I / F 16 (step S307).

  FIG. 16 is a diagram showing a screen 110 when the operator designates the verification area 66. Note that the screen 110 shown in FIG. 16 is an example in which the matching region 66 is determined again at the designated reference point, and therefore the vertical pattern line 71 and the horizontal pattern line 72 of the physical pattern 70 are displayed. Has been. However, when the region 66 for verification is first determined, the pattern line 71 and the pattern line 72 do not exist, while the pattern lines 61 and 62 of the theoretical pattern 60 may exist.

  The operator selects a designated reference point (for example, the approximate center of the vertical pattern line 61 and the horizontal pattern line 62), and determines the size of the matching region 66 centered on the selected designated reference point. Then, the image in the verification area 66 is stored in the HDD 15.

  Returning to FIG. 12, following step S307, the CPU 11 searches for each reference point using coordinate points based on the theoretical pattern 40 (step S308). In the search, a reference point is specified from a portion that matches the image of the matching region 66. However, the match with the image in the verification region 66 may be a perfect match, or may be a determination that takes into account a certain amount of error such as a match of 90% or more instead of a complete match.

  Next, following the search for all the reference points, the CPU 11 executes the production of the physical pattern 70 that connects all the reference points (step S309). Next, the CPU 11 enters a standby state in which it is determined whether or not there is a manual editing instruction (step S310). If there is a manual editing instruction by the operator, the CPU 11 returns to step S307, and the reference that has been manually changed. The point is regarded as a designated reference point, and another reference point is searched again.

  FIG. 17 is a diagram illustrating a screen 110 in a state where the physical pattern 70 is displayed superimposed on the composite image of the actual patterned fabric 60. As shown in FIG. 17, in this embodiment, a physical pattern 70 having substantially the same form as the lattice pattern of the composite image of the actual patterned fabric 60 is produced.

  FIG. 18 is a diagram showing a screen 110 when the operator moves the reference point 155 that is greatly deviated from the synthesized image of the actual patterned fabric 60 when the operator wants to correct the physical pattern 70.

  When the operator checks the reference point automatically set and finds that the reference point 155 in the region M is deviated from the composite image of the actual pattern material 60, the pointing device is used to set the reference point 155 to the correct intersection point position. It can move in the direction (in FIG. 18, for example, the direction of arrow N). Then, it returns to step S307 shown in FIG. 12, and production of the physical pattern 70 is performed again.

  Returning to FIG. 12, if the result of determination in step S <b> 310 is that there is no manual editing instruction, the CPU 11 determines whether or not the operator has received an instruction command for a scratch part area input by clicking the scratch part instruction key 117. (Step S311). Here, the scratched part means a defective part that is not suitable for placing the component part 80, such as a scratch or dirt present on the patterned fabric 8. If no flaw part area is designated, when the operator gives an instruction to place the component part 80 by clicking the placement start key 120, the CPU 11 accepts the instruction command via the I / F 16 (step S313). Subsequently, the CPU 11 reads out the coordinate point of each component part 80 from the HDD 15 (step S314).

  The CPU 11 arranges one component part 80 based on the read coordinate points (step S315). Subsequently, another component part 80 relatively determined at the position of the previous component part 80 is arranged (step S316). The CPU 11 determines whether or not all the constituent parts 80 have been arranged (step S317), and arranges the constituent parts 80 one by one until the arrangement of all the constituent parts 80 is completed. When the arrangement of all the constituent parts 80 is completed by the determination in step S317, the CPU 11 obtains the distance from the origin 131 in the length direction of the rectangular area including all the constituent parts 80 in the composite image of the actual patterned fabric 60 (step S317). S318). Subsequently, the CPU 11 determines whether or not a predetermined time (for example, one minute) for arranging the component parts 80 has elapsed (step S319).

  As a result, if the predetermined time has not been reached, the process returns to step S316 and the arrangement of the component parts 80 is continued. On the other hand, when the predetermined time is reached, the CPU 11 selects an arrangement pattern having the shortest distance from the origin 131 among the arrangements of the component parts 80 executed a plurality of times (step S320).

  FIG. 19 is a diagram showing a screen 110 when the operator arranges the component parts 80.

  When the component part 80 is arranged or when the component part 80 is arranged within a predetermined time and then arranged under another condition, the operator instructs the arrangement start key 120. The CPU 11 accepts the instruction and displays an automatic placement dialog box 160. The automatic arrangement dialog box 160 is provided with a time input field 161, result confirmation necessity fields 162, 163, an arrangement start instruction key 164, and a cancel key 165. The time input column 161 is a column for setting a time limit for performing the arrangement process of the component part 80 by an operator's input operation. The result confirmation necessity columns 162 and 163 are columns for selecting whether or not to display the arrangement results one by one. The result confirmation necessity column 162 (“None” display column) is a column to be selected when display of the arrangement result is not desired. On the other hand, the result confirmation necessity / unnecessity column 163 (“Yes” display column) is a column to be selected when it is desired to display the arrangement result. The arrangement start instruction key 164 is a key for starting arrangement processing of the component part 80. A cancel key 165 is a key for canceling the arrangement process.

  In addition, display fields 170 to 174 are provided on the screen 110 shown in FIG. In the display field 170, a marker name (for example, “pattern matching”) is displayed. In the display columns 171 to 174, arrangement conditions are displayed. Further, in the display column 122, the arrangement result of all the arrangement parts 80 is displayed immediately after the arrangement of the component parts 80 by the operator's selection.

  Returning to FIG. 12, following step S320, the CPU 11 displays an arrangement pattern (best arrangement pattern) in which the distance from the origin 131 in the length direction of the occupied rectangular area of all the component parts 80 is the shortest (step arrangement). S321). Next, the CPU 11 converts the data of each component part 80 based on the best arrangement pattern into NC data (step S322). Next, the CPU 11 transmits NC data to the cutting machine control device 2 (step S323).

  On the other hand, when the operator sends a command for a wound part area in step S311, the CPU 11 recognizes the specified wound part area as a fixed component (fixed part) and sends it to the HDD 15. Store (step S312).

  FIG. 20 is a diagram showing a screen 110 when the operator designates the scratch part areas 180 and 181. FIG. 21 is a diagram showing a result of the arrangement of the constituent parts 80 after designation of the flaw part areas 180 and 181.

  When the operator presses the scratched part instruction key 117 after the physical pattern 70 is manufactured, the automatic pattern matching apparatus 1 is in a state in which a part where a scratch or dirt exists can be designated. When the operator starts the placement process after surrounding the scratched or soiled portion with the scratched part areas 180 and 181 while viewing the composite image of the actual patterned fabric 60 displayed on the display, the CPU 11 displays the area. The components are recognized as fixed component parts, and the component parts 80 are arranged in addition to those regions. As a result, as shown in FIG. 21, the scratch part areas 180 and 181 shown in FIG. 20 are displayed as fixed parts 180a and 181a as shown by diagonal lines when the arrangement pattern of the component parts 80 is displayed.

  When the process of step S323 is completed, as shown in FIG. 13, the cutting machine control device 2 receives NC data from the automatic pattern matching device 1 (step S401), and aligns the origin 131 with the origin on the cutting machine ( In step S402, based on the NC data, the pattern material 8 is cut (step S403).

  Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and can be implemented in various modified forms.

  The above-described embodiment is an example in which the patterned fabric 8 having a lattice pattern is used. However, as long as the pattern exists, the present invention is not limited to the lattice pattern and can be applied to a patterned fabric having another pattern.

  FIG. 22 is a diagram for explaining a method of cutting out the constituent parts of clothing from the patterned fabric 190 having a pattern 191 other than the lattice pattern. (22A) shows the component part 41 on the theoretical pattern 192, and (22B) shows the component part 51 on the physical pattern 195, respectively.

  The patterned fabric 190 has many circular patterns 191. The theoretical pattern 192 of the patterned fabric 190 is a regular coordinate system (matrix). On the other hand, the physical pattern 195 is produced based on the composite image of the patterned fabric 190 actually stretched on the table 7, so that the coordinate system (actual matrix) is distorted partially or entirely. Become. In FIG. 22, a matrix is constituted by a vertical axis and a horizontal axis passing through the center of the handle 191. However, the matrix may be configured by a vertical axis and a horizontal axis passing through a specific position of the handle 191.

  The component 41 on the theoretical pattern 192 is placed on the physical pattern 195 as it is (that is, as shown in the thick dotted line area in FIG. 22 (22B)), and even if it is cut, the actual patterned fabric 190 is wrinkled. Due to the distortion, the continuity of the pattern is lost at the boundary of each component part. Therefore, for example, as shown by a thick solid line in FIG. 22 (22B), if the constituent parts 51 are arranged and cut based on the physical pattern 195, the continuity of the pattern 191 can be ensured.

  Thus, even if the pattern is not a lattice, as long as a real matrix using the pattern is produced, the constituent parts 51 that match the actual patterned fabric can be arranged, the continuity of the pattern, etc. Can be secured.

  In the above-described embodiment, three types of devices are employed, that is, the automatic pattern matching device 1, the cutting machine control device 2, and the imaging device control device 3. However, one or two types of devices are employed. Also good. For example, when one type of device is employed, the one type of device may have all the functions of the automatic pattern matching device 1, the cutting machine control device 2, and the imaging device control device 3.

  The automatic pattern matching program of the present invention is a program that can be installed and executed in the HDD 15 in the above-described embodiment. The program can be stored in an information recording medium such as a CD-ROM, MD, or FD, and can be traded in the market. It is also possible to download the automatic pattern matching program of the present invention from a server connected to the automatic pattern matching apparatus 1 through a communication line such as the Internet, store the program in the HDD 15 and execute it.

  Also, the CPU 11 receives imaging data reception means, display processing means, designated reference point reception means, reference point search means, actual matrix preparation means, component parts arrangement means, component parts arrangement data transmission means, defective part reception means, and reference point change. It also serves as a reception means. In addition to the CPU 11, an MPU (Micro Processing Unit) may be independently employed or used together. When the MPU is used in place of the CPU 11, the MPU uses an imaging data receiving unit, a display processing unit, a designated reference point receiving unit, a reference point searching unit, a real matrix creating unit, a component part arranging unit, and a component part arranging data. It also serves as a sending unit, a defective portion receiving unit, and a reference point change receiving unit. Moreover, when using CPU11 and MPU, CPU11 and MPU can also share each above-mentioned means.

  The HDD 15 is a storage unit, but the RAM 13 or the EEPROM 14 may be a storage unit.

  In the above-described embodiment, the actual matrix has a lattice shape, but may have any shape other than the lattice, for example, a plurality of points, a cross shape, a set of rhombuses, and the like. If it becomes a matrix which can pinpoint the position of a handle, it will not be limited to a lattice shape. In addition, the arrangement process of each component part 80 is preferably performed a plurality of times within a predetermined time, but may be performed only once.
