Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived from the embodiments given herein by one of ordinary skill in the art, are within the scope of the invention.
In order to accurately measure the width information of the glue coating, the embodiment of the invention provides a width information determining method, a device and electronic equipment.
It should be noted that, in a specific application, the embodiment of the present invention may be applied to various electronic devices, for example, a personal computer, a server, a mobile phone, and other devices with data processing capability. Moreover, the method for determining width information provided by the embodiment of the present invention may be implemented by software, hardware, or a combination of software and hardware.
The method for determining width information provided by the embodiment of the invention can comprise the following steps:
acquiring a gluing image containing a gluing area, wherein the gluing area is a glued area in a gluing part;
performing edge recognition on a gluing area in the gluing image to obtain a first edge and a second edge of the gluing area;

In the above scheme of the embodiment of the invention, after the glue coating image is obtained, the first edge and the second edge of the glue coating area can be identified, and then the width information between the first edge and the second edge is determined by using the distance information between each pixel point and the matching pixel point in the first edge and the second edge, so that the distance identification at the pixel level can be realized, and the accuracy of the determined width information is higher. Furthermore, because the embodiment of the invention can automatically realize the measurement of the width information after the gluing image is obtained, compared with a manual measurement mode, the efficiency is higher, and because the selection of a measurement point by an operator is not needed, the cost of the measurement of the width information can be reduced.
The following describes the width information determining method provided by the embodiment of the present invention in detail with reference to the drawings.
As shown in fig. 1, an embodiment of the present invention provides a method for determining width information, including steps S101 to S103, where:
s101, obtaining a gluing image containing a gluing area, wherein the gluing area is a glued area in a gluing part;
the glue coating part may be a part involved in the screen panel production process, for example, a component constituting the screen panel, such as a backlight module, a polarizer, a glass substrate, and the like. In the screen panel production process, a glue coating process is required to be applied to part or all of the constituent elements of the screen panel to bond them to other elements, and in the embodiment of the present invention, the area in which glue has been coated in the glue coating element is referred to as a glue coating area.
It should be emphasized that, in the production process of other devices, the gluing process and the width information measurement of the gluing may also be involved, and the width information method provided in the embodiment of the present invention is also applicable thereto, and the screen panel mentioned in the embodiment of the present invention is merely illustrated as an example and is not to be construed as a limitation of the present invention.
The gluing image may be acquired from the gluing part after the gluing process is applied to the gluing part. In different scenes, due to the difference of the sizes and requirements of the related gluing parts, the gluing image can be an image related to the whole gluing area of the gluing part or a local gluing area in the gluing part. Illustratively, as shown in fig. 2 (a), the image of the glue application provided by the embodiment of the present invention is a schematic view of the glue application image related to the whole glue application area of the glue application part, as shown in fig. 2 (b), the image of the glue application provided by the embodiment of the present invention is another schematic view of the glue application image related to the partial glue application area in the glue application part, as shown in fig. 2 (b), and the gray area in fig. 2 (a) and 2 (b) is the glue application area. Compared with the gluing image of the whole gluing area, the gluing image related to the local gluing area can show more details, so that in a scene with higher precision requirement, the width information of the gluing image related to the local gluing area is mostly used for confirmation.
In this step, the gluing image may be acquired in combination with an actual application scenario or a requirement, for example, in an implementation manner, a camera that acquires the gluing image may be independent of the execution main body of the embodiment of the present invention, and at this time, the gluing image may be read from the camera, or the gluing image acquired by the camera may also be acquired in advance by another electronic device, and further transmitted to the execution main body of the embodiment of the present invention in a task, instruction, or other manner, and at this time, the execution main body of the embodiment of the present invention may receive the width information determination task and instruction, and then read the gluing image carried by the task and instruction, or read the gluing image from a storage location specified by the task and instruction, which is all possible. In another implementation manner, the execution main body according to the embodiment of the present invention may include a camera for acquiring the gluing image, and in this case, the step may be to control the camera to acquire the gluing image acquired by the camera.
S102, performing edge recognition on a gluing area in the gluing image to obtain a first edge and a second edge of the gluing area;
in order to determine the width information of the glue-coated area, after obtaining the glue-coated image, edge recognition may be performed on the glue-coated area in the glue-coated image. In this step, the edge of the glue area can be identified in various ways. For example, in one implementation, the edge detection algorithm may be used to process the glue-coated image to obtain the first edge and the second edge of the glue-coated region in the glue-coated image, and the edge detection algorithm used may include an algorithm that performs edge recognition by using a first-order operator and a second-order operator, such as a cross differential operator. In another implementation manner, a neural network model may also be used, specifically, a neural network model for edge recognition may be trained in advance, and then the pre-trained neural network model is used to process the glue-coated image to obtain the first edge and the second edge of the glue-coated region in the glue-coated image. Because the neural network model can be trained by using the images acquired in the gluing process scene, compared with an edge detection algorithm, the neural network model can be more suitable for edge recognition in the gluing process scene, so that the accuracy of the edge recognition can be improved.
In order to more accurately perform edge recognition on the gluing area, in one implementation, before performing edge recognition on the gluing area in the gluing image to obtain the first edge and the second edge of the gluing area, the gluing image may be further preprocessed, for example, the gluing area is recognized on the gluing image to determine the gluing area in the gluing image.
In the embodiment of the invention, the gluing area identification can be carried out on the gluing image in various modes, for example, the gluing image is divided into areas, and then the gluing area is identified from the divided areas by using the texture characteristics in different areas. Or the pre-trained neural network model for identifying the gluing area can be used for processing the gluing image and determining the gluing area from the gluing image.
After the gluing area is identified from the gluing image, the step of identifying the gluing area of the gluing image to determine the gluing area in the gluing image can be executed.
Illustratively, as shown in fig. 3 (a), a schematic diagram of edge recognition provided by the embodiment of the present invention, the first edge and the second edge in the glue image in fig. 3 (a) are obtained by performing edge recognition on the glue area in the glue image in fig. 2 (a). As shown in fig. 3 (b), another schematic diagram of edge recognition is provided according to an embodiment of the present invention, in which the first edge and the second edge in the glue image in fig. 3 (b) are obtained by performing edge recognition on the glue area in the glue image in fig. 2 (b).
S103, determining width information between the first edge and the second edge as width information of the gluing area based on distance information between each pixel point and the corresponding matching pixel point in the first edge and the second edge;
after the first edge and the second edge are determined, width information between the first edge and the second edge may be determined based on distance information between each pixel point and the corresponding matching pixel point in the first edge and the second edge, and then the determined width information is used as width information of the gluing area. The distance information is a pixel distance between two pixels, or a square of the pixel distance, and certainly, other information that can feedback the distance may be used.
The matching pixel points corresponding to each pixel point are as follows: and the pixel point which belongs to different edges and has the minimum distance with the pixel point. In short, for each pixel point in the first edge, the corresponding matching pixel point is necessarily one pixel point in the second edge, and the specific pixel point is the pixel point with the minimum distance from the pixel point in the first edge among the pixel points included in the second edge. Exemplarily, the first edge includes a pixel 1 and a pixel 2, and the second edge includes a pixel 3 and a pixel 4, wherein a distance between the pixel 1 and the pixel 3 is smaller than a distance between the pixel 1 and the pixel 4, and a distance between the pixel 2 and the pixel 3 is greater than a distance between the pixel 2 and the pixel 4, so that the matching pixel of the pixel 1 is the pixel 3, the matching pixel of the pixel 2 is the pixel 4, and similarly, the matching pixel of the pixel 3 is the pixel 1, and the matching pixel of the pixel 4 is the pixel 2.
It should be noted that, in general, for the pixels in the first edge and the second edge, the pixels and the matching pixels thereof are often matching pixels, such as the above-mentioned pixel 1 and pixel 3, and pixel 2 and pixel 4. However, in a special case, there is also a matching pixel of a certain pixel, and the matching pixel of the matching pixel is not the pixel, for example, the matching pixel of the pixel 5 in the first edge is the pixel 6 in the second edge, and the matching pixel of the pixel 6 may not be the pixel 5 in the first edge, for example, may be the pixel 7 in the first edge.
Because the matching pixel point of each pixel point is the pixel point which belongs to different edges and has the minimum distance with the pixel point, the distance information between each pixel point and the matching pixel point can represent the width of the gluing area at the position of the pixel point. Therefore, after the first edge and the second edge are determined, the width information between the first edge and the second edge can be determined based on the distance information between each pixel point and the corresponding matched pixel point, and the width information is used as the width information of the gluing area.
In the embodiment of the present invention, there are various ways to determine the width information between the first edge and the second edge, and for example, in one implementation, a target pixel may be selected from the pixels included in the first edge and the second edge, and then the distance information between the target pixel and the matching pixel thereof is used as the width information between the first edge and the second edge. Or, the mean value represented by the distance information between each pixel and its matching pixel may also be used as the width information between the first edge and the second edge.
In order to enable the determined width information to reflect the quality of the gluing process more accurately and comprehensively, in the embodiment of the present invention, the width information of the gluing area may be the maximum width and/or the minimum width between the first edge and the second edge.
In this case, the determination may be made in the following manner, including:
determining minimum distance information from the distance information between each pixel point and the corresponding matched pixel point in the first edge and the second edge, and taking the distance represented by the determined distance information as the minimum width of the gluing area; and/or the presence of a gas in the atmosphere,
determining the maximum distance information from the distance information between each pixel point and the corresponding matching pixel point in the first edge and the second edge, and taking the distance represented by the determined distance information as the maximum width of the gluing area;
and taking the minimum width and/or the maximum width as the width information of the gluing area.
Illustratively, the first edge comprises a pixel point a, a pixel point b and a pixel point c, the second edge comprises a pixel point d, a pixel point e and a pixel point f, wherein the pixel point a and the pixel point d are matched pixel points, the distance information is distance ad, the pixel point b and the pixel point e are matched pixel points, the distance information is distance be, the pixel point c and the pixel point f are matched pixel points, the distance information is distance cf, the distance ad is less than the distance cf and less than the distance be, the minimum distance information is determined to be the distance ad, namely, the minimum width of the gluing area is the distance ad, the maximum distance information is determined to be the distance be, and namely, the maximum width of the gluing area is the distance be. At this time, the determined width information of the glue application area is false: minimum width: distance ad, and/or maximum width: the distance be.
In the above scheme of the embodiment of the invention, after the glue-coated image is obtained, the first edge and the second edge of the glue-coated area can be identified, and then the width information between the first edge and the second edge is determined by using the distance information between each pixel point and the matched pixel point in the first edge and the second edge, so that the distance identification at the pixel level can be realized, and the accuracy of the determined width information is higher. Furthermore, the embodiment of the invention can automatically realize the measurement of the width information after the gluing image is obtained, has higher efficiency compared with a manual measurement mode, and can reduce the cost of the measurement of the width information because the operator does not need to select the measurement point.
In order to further improve the accuracy of the obtained width information, in an implementation manner of step S103 in the embodiment of the present invention, the first edge and the second edge may be edge-corrected based on edge end points of the first edge and the second edge, and then the width information between the first edge and the second edge is determined based on distance information between each pixel point and the corresponding matching pixel point in the first edge after the edge correction and the second edge after the edge correction, and is used as the width information of the gluing area.
The edge end point of the first edge and the second edge may be a starting point or an ending point of the first edge and the second edge, for example, an intersection point of the first edge and the second edge with the image edge in the glue-coated image shown in fig. 3 (b). Edge modification of the first edge and the second edge may include smoothing the edges, breakpoint optimization, and the like. Optionally, when the gummed image only relates to a local gummed region, the first edge and the second edge often have end points with an image edge camera, and for a pixel point of an end point accessory, distance information between the pixel point and a corresponding matching pixel point is often large. For example, as shown in fig. 4, an embodiment of the present invention provides an edge schematic diagram in a glued image, which includes a first edge AB and a second edge CD, and due to the limitation of the sampling range of the glued image, for a pixel C in the second edge, a corresponding matching pixel is a pixel a, so that the distance between the matching pixel and the pixel is a distance AC, and the distance is significantly large, so that the pixel C is a redundant pixel.
Because the pixel points in the corrected first edge and the corrected second edge are more accurate, the width information between the first edge and the second edge can be determined by utilizing the distance information between each pixel point and the corresponding matched pixel point in the first edge after the edge correction and the second edge after the edge correction, and the accuracy of the width information determination can be improved.
In one implementation manner, the edge endpoint referred to in this embodiment of the present invention may include: a first endpoint and a second endpoint of the first edge, and a third endpoint and a fourth endpoint of the second edge. For example, for fig. 4, the first endpoint is a, the second endpoint is B, the third endpoint is C, and the fourth endpoint is D.
In this case, the first edge may be edge-corrected based on the third end point and the fourth end point. If the pixel points contained in the first edge are determined, the pixel point with the minimum distance from the third end point is used as a first alternative pixel point, the pixel point with the minimum distance from the fourth end point is determined and used as a second alternative pixel point, and then the pixel points which do not belong to the range of the first alternative pixel point and the second alternative pixel point in the pixel points contained in the first edge are determined as redundant pixel points in the first edge, and finally the redundant pixel points in the pixel points contained in the first edge are eliminated.
Further, the second edge may be edge-corrected based on the first end point and the second end point. If the pixel points with the minimum distance from the first end point are determined from the pixel points contained in the second edge to be used as a third alternative pixel point, the pixel points with the minimum distance from the second end point are determined to be used as a fourth alternative pixel point, and then the pixel points which do not belong to the range where the third alternative pixel point and the fourth alternative pixel point are located in the pixel points contained in the second edge are determined to be redundant pixel points in the second edge, and the redundant pixel points in the pixel points contained in the second edge are eliminated.
To explain with the example shown in fig. 4, for the first edge, the matching pixel point of the first endpoint a is pixel point E, the matching pixel point of the second endpoint B is pixel point F, the matching pixel point of the third endpoint is pixel point a, and the matching pixel point of the fourth endpoint D is pixel point B, so that for the first edge, the first edge does not include redundant pixel points, and the correction is the same before and after. For the second edge, the modified second edge only includes the pixel points in the segment EF, the segment CE, and the pixel points in the segment FD as redundant pixel points to be eliminated.
In an implementation manner, the method can also be implemented by combining a pixel point set manner, and specifically, the pixel point set of the first edge can be set to be p 1 The set of pixel points of the second edge is p 2 And:
p 1 ＝[p 11 ，p 12 ，...，p 1(n-2) ，p 1(n-1) ]
p 2 ＝[p 21 ，p 22 ，...，p 2(m-2) ，p 2(m-1) ]
wherein n is the number of pixels included in the first edge, and m is the number of pixels included in the second edge.
Let the first end be p 10 The second end point is p 1(n-1) And the third endpoint is p 20 The fourth end point is p 2(m-1) Calculating the first endpoint p 10 Set of pixels p 2 Distance information for all pixels, e.g. for convenience of calculation, the distance information may be the square of the distance, i.e. the distance

Further recording corresponding pixel point set p 1 And a set of pixel points p 2 The index positions j, k and l of the coordinate points in (1).
Because the corresponding relation between the endpoint of the pixel point set and the edge endpoint of the image gluing is uncertain, i and j need to be compared, specifically:
if i is less than j, then the pixel point set p 2 All the pixel points with index positions from i to j are taken out as effective pixel points, namely
p 2i ，p 2(i+1) ，…，p 2(j-1) ，p 2j
Set of pixel points p 2 The other pixel points in the group are redundant pixel points;
if j is less than i, then the pixel point set p 2 All pixel points with index positions from j to i are taken out in a point set and taken as effective pixel points, namely

According to the technical scheme of the embodiment of the invention, after the gluing image is obtained, the accuracy of width information determination can be improved, the efficiency is higher, and the cost of width information measurement can be reduced. Meanwhile, before the width information is determined, the accuracy of the width information can be further improved by correcting the first edge and the second edge.
In an embodiment, before performing step S103, distance information between each pixel point of the first edge and the second edge and the corresponding matching pixel point may also be determined. It should be emphasized that, in this embodiment, the first edge and the second edge to be referred to may be the corrected first edge and the corrected second edge obtained by the aforementioned edge correction, or may be the first edge and the second edge without the edge correction.
Optionally, before step S103 is executed, distance information between each pixel point in the first edge and each pixel point in the second edge may be determined, and then for each pixel point in the first edge and the second edge, the minimum distance information is determined from the distance information between the pixel point and each corresponding pixel point to be screened, and the minimum distance information is used as the distance information between the pixel point and the corresponding matching pixel point, where the pixel point to be screened corresponding to each pixel point is a pixel point belonging to a different edge from the pixel point.
In one implementation, the distance information matrix d may be constructed based on distance information between each pixel point in the first edge and each pixel point in the second edge:
wherein n is the number of pixels contained in the first edge, m is the number of pixels contained in the second edge, and each d in the distance information matrix d uv And representing the distance information between the u-th pixel point in the first edge and the v-th pixel point in the second edge, wherein u is more than or equal to 1 and less than or equal to n, and v is more than or equal to 1 and less than or equal to m.
And then determining the minimum distance information in each row in the distance information matrix d as the distance information between the pixel point of the row and the corresponding matching pixel point, and determining the minimum distance information in each column in the distance information matrix d as the distance information between the pixel point of the column and the corresponding matching pixel point.
For the convenience of subsequent calculation, the first distance information matrix d may be constructed after determining the minimum distance information in each row of the distance information matrix d row ：
d row ＝[d 1row ，d 2row ，…，d (n-1)row ，d nrow ]
Wherein the first distance information matrix d row Each of d in urow Representing the minimum distance information in the u-th row in the distance information matrix d;
after determining the minimum distance information in each column in the distance information matrix d, a second distance information matrix d is constructed col ：
d col ＝[d 1col ，d 2col ，…，d (m-1)col ，d mcol ]
Wherein the second distance information matrix d col Each of d in vcol Representing the minimum distance information in the v-th column in the distance information matrix d;
in this case, determining the width information between the first edge and the second edge based on the distance information between each pixel point and the corresponding matching pixel point in the first edge and the second edge as the width information of the glue coating area may include determining a first distance information matrix d row And a second distance information matrix d col The minimum distance information and the maximum distance information in (1) are respectively marked as d rowmin 、d rowmax And dc olmin 、d colmax Then calculate d rowmin And d colmin Minimum value of (d) min Calculating d rowmax And d colmax And is noted as d max Finally d is min And d max As width information of the glue application area.
It should be emphasized that the distance information may be a pixel distance between two pixels, or may be a square of the pixel distance between two pixels. If the distance information is a pixel distance flat method, after the minimum distance information and the maximum distance information are determined, the minimum distance information and/or the maximum distance information can be used as the width information of the gluing area.
In the above scheme of the embodiment of the invention, after the gluing image is obtained, the accuracy of width information determination can be improved, the efficiency is higher, and the cost of width information measurement can be reduced. Meanwhile, before the width information is determined, the distance information between each pixel point in the first edge and the second edge and the corresponding matching pixel point is determined, so that a realization basis can be provided for improving the accuracy.
