In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, 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 some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a schematic view of an application scenario of an identification code identification method according to an embodiment of the present invention. Referring to fig. 1, the terminal device may be a mobile phone, a computer, or other devices, wherein the terminal device has an image capturing device, so that the terminal device can scan the identification code through the image capturing device. The terminal device also has an identification function of an identification code, which may be integrated into an application installed in the terminal device, for example, the identification function may be integrated into a camera application, the identification function may be integrated into a wechat application, and so on.
In the application, after the terminal device completes one-time identification of the identification code, the terminal device may generate an identification record of the current identification, so that a historical identification record is stored in the terminal device, and optionally, the historical identification record may include an identification focal length, an identification time, an identification duration, and the like of successful identification. When the terminal device needs to identify the identification code, the terminal device may determine the N most frequently used identification focal lengths of the user according to the historical identification record, identify the identification code according to the N identification focal lengths, and identify the identification code through an automatic focusing mode when the identification code cannot be successfully identified according to the N identification focal lengths. In the practical application process, when the same user identifies the identification code, the distance between the camera and the identification code is usually related to the habit of the user, for example, the distance between the camera and the identification code is far when part of the user is used, and the distance between the camera and the identification code is far when part of the user is used; the distance between the camera and the identification code is related to the identification focal length, and the habit of a user is fixed for the same user, so that the distance between the camera and the identification code is usually fixed when the user identifies the identification code, and in the identification process of the identification code, the N identification focal lengths obtained according to the historical identification record are determined to be the identification code which can be successfully identified usually, and the identification efficiency of the identification code is improved without multiple times of identification in an automatic focusing mode.
The technical means shown in the present application will be described in detail below with reference to specific examples. It should be noted that the following embodiments may be combined with each other, and the description of the same or similar contents in different embodiments is not repeated.
Fig. 2 is a flowchart illustrating an identification code identification method according to an embodiment of the present invention. Referring to fig. 2, the method may include:
s201, receiving an identification instruction input by a user, wherein the identification instruction is used for indicating that the first identification code is identified through an image pickup device in the terminal device.
The execution main body of the embodiment of the invention can be terminal equipment, and also can be an identification device arranged in the terminal equipment. Alternatively, the identification means may be implemented by software, or the identification means may be implemented by a combination of software and hardware.
Optionally, the identification code in the embodiment of the present invention may include a two-dimensional code, a barcode, and the like, and certainly, in an actual application process, the identification code may be set according to an actual need, which is not specifically limited in the embodiment of the present invention.
Optionally, the identification function of the identification code may be integrated in the camera application program of the terminal device, and since the camera application programs are installed in most terminal devices, the user directly recognizes the identification code through the camera application program without additionally installing an application program with the identification code identification function, thereby improving the user experience.
When the recognition function of the identification code is integrated in the camera application of the terminal device, the user can input a recognition instruction in the camera application. For example, the user may start a camera application program and perform a click operation on a preset button in the camera application program to input a recognition instruction in the terminal device.
Of course, in order to enable the user to input the identification instruction in the terminal device quickly, the user may perform a preset type of operation on a preset key in the terminal device to implement the input of the identification instruction in the terminal device. For example, the user may perform a double-click operation on a power-on key of the terminal device to input the identification instruction in the terminal device.
S202, determining N identification focal lengths according to the historical identification records of the terminal equipment, wherein N is a positive integer greater than or equal to 1.
Optionally, the historical identification record of the terminal device may be all the historical identification records of the terminal device, or may be the historical identification record of the terminal device within a preset time period, where the preset time period may be 3 months, 6 months, a year, and the like.
Alternatively, the historical identification record may be an identification record of successful identification of the identification code. Optionally, the historical identification record may include an identification focal length when the identification code is successfully identified, and of course, the historical identification record may further include an identification time, an identification duration, and the like. In an actual application process, the content included in the history identification record may be set according to actual needs, and this is not specifically limited in the embodiment of the present invention.
Optionally, the identification focal lengths in the historical identification record may be counted to obtain N identification focal lengths, where the N identification focal lengths are the N identification focal lengths with the highest identification success rate in the historical identification record of the terminal device.
It should be noted that, in the embodiment shown in fig. 3, a process of obtaining N identification focal lengths is described in detail, and details are not repeated here.
It should be further noted that the N identification focal lengths may also be preset for the terminal device. For example, since most users are accustomed to a code scanning distance of 17 cm to 35 cm when performing the identification code scanning, the N identification focal lengths may be set to 30 cm, 26 cm, and 22 cm for the code scanning distance.
And S203, identifying the first identification code through the camera equipment according to the N identification focal lengths.
Optionally, the identifying the first identification code may be implemented by the following steps a and B:
step A, identifying a first identification code according to the Nth identification focal length, and judging whether the first identification code is successfully identified;
step B, if the first identification code is not successfully identified, adding 1 to the value of N, and executing the step A until the first identification code is successfully identified; wherein, initially, N is 1.
In the practical application process, the identification success rate corresponding to each of the N identification focal lengths may be obtained, and the N identification focal lengths are sorted according to the sequence of the identification success rate corresponding to each identification focal length from high to low.
For example, the identification success rate corresponding to each identification focal length may be obtained through the following feasible implementation manners, assuming that the terminal device performs 100 times of successful identification codes, where the identification focal length for 60 times is 30 centimeters, the identification focal length for 25 times is 35 centimeters, the identification focal length for 10 times is 20 centimeters, and the terminal device obtains 3 identification focal lengths that are 30 centimeters, 35 centimeters, and 20 centimeters respectively, where the identification success rate corresponding to 30 centimeters is: 60/100 is 0.6, and the recognition success rate for 35 cm is: 25/100 is 0.25, and the recognition success rate for 20 cm is 10/100 is 0.1.
In the process of identifying the first identification code, the terminal equipment identifies the first identification code according to the first identification focal length, if the identification is successful, the process is ended, if the identification is failed, the first identification code is identified according to the second identification focal length, if the identification is successful, the process is ended, if the identification is failed, the first identification code is identified according to the third identification focal length, and so on until the first identification code is successfully identified, or the first identification code is still unsuccessfully identified when the value of N is greater than a preset threshold value.
It should be noted that, when the first identification code cannot be successfully identified according to the N identification focal lengths, the first identification code may be identified in an automatic focusing manner.
It should be further noted that, in the embodiment of the present invention, when the identification function is integrated in the camera application, after the terminal device successfully identifies the identification code, the page jump may be performed according to the identified identification code. For example, if the terminal device recognizes the commodity detail information, a webpage corresponding to the commodity detail information can be directly opened, and if the terminal device recognizes the WeChat friend business card, a WeChat interface can be called to start WeChat, and a friend adding page in the WeChat can be skipped to.
According to the identification code identification method provided by the embodiment of the invention, when the terminal equipment needs to identify the identification code, the terminal equipment firstly determines N identification focal lengths according to the historical identification record, the N identification focal lengths are the N identification focal lengths with the highest identification success rate in the historical identification record, the terminal equipment firstly identifies the first identification code according to the N identification focal lengths, and when the first identification code cannot be successfully identified according to the N identification focal lengths, the first identification code is identified in an automatic focusing mode. For the same user, the habit of the user is relatively fixed, so that when the user identifies the identification code through the terminal equipment, the distance between the camera and the identification code is generally relatively fixed, and N identification focal lengths obtained according to the historical identification record are determined to be related to the habit of the user, therefore, in the process of identifying the first identification code, the first identification code can be generally and successfully identified according to the N identification focal lengths obtained through determination, and the identification efficiency of the identification code is further improved.
Based on the embodiment shown in fig. 2, the following describes in detail a process of determining N identification focal lengths (S202 in the embodiment shown in fig. 2) according to the historical identification records of the terminal device by the embodiment shown in fig. 3, specifically, please refer to the embodiment shown in fig. 3.
Fig. 3 is a schematic flowchart of a method for obtaining N identification focal lengths according to an embodiment of the present invention. Referring to fig. 3, the method may include:
s301, at least one history identification record of the terminal equipment is obtained.
Optionally, after the terminal device successfully identifies one identification code each time, the terminal device stores the corresponding historical identification record in the preset storage space. Accordingly, the terminal device may obtain at least one history identification record of the terminal device in the preset storage space.
S302, acquiring the identification focal distance corresponding to each historical identification record.
The identification focal distance corresponding to the historical identification record is as follows: and in the identification process corresponding to the historical identification record, the identification focal length is used when the identification code is successfully identified.
And S303, counting the number of the identification focal lengths corresponding to the plurality of preset focal length sections according to the identification focal length corresponding to each historical identification record.
The preset focal length is a preset focal length range, for example, the plurality of preset focal length sections may be 20-25 cm, 25.1-30 cm, 30.1-35 cm, and the like. Of course, in an actual application process, the plurality of preset focal length segments may be set according to actual needs, which is not specifically limited in the embodiment of the present invention.
Optionally, the preset focal length section where the identification focal length corresponding to each historical identification record is located may be determined, and the number of the identification focal lengths corresponding to the plurality of preset focal length sections may be counted according to the preset focal length section where the identification focal length corresponding to each historical identification record is located.
S304, determining N target focal length sections in the plurality of preset focal length sections according to the number of the identification focal lengths corresponding to the plurality of preset focal length sections.
Optionally, the N preset focal length segments with the largest number of corresponding identification focal lengths may be determined as the N target focal length segments.
S305, respectively determining the focal lengths corresponding to the N target focal length sections as N identification focal lengths.
Each focal length segment has its corresponding identification focal length, e.g., focal lengths 20-25 cm may correspond to an identification focal length of 22.5 cm, and focal lengths 25.1-30 cm may correspond to an identification focal length of 27.5 cm.
It should be noted that, in an actual application process, the identification focal length corresponding to each focal length segment may be determined according to actual needs, which is not specifically limited in the embodiment of the present invention.
It should be further noted that, because the habit of the user usually does not change frequently, in the actual application process, the terminal device may periodically execute the technical scheme shown in the embodiment of fig. 3, for example, execute the technical scheme shown in the embodiment of fig. 3 once every week or every month, to determine N identification focal lengths at a time, and store the N identification focal lengths obtained by the determination, so that, in the subsequent identification process, it is only necessary to directly obtain the stored N identification focal lengths, and thus, the efficiency of obtaining the N identification focal lengths may be improved.
The technical solutions shown in the above method embodiments are described in detail below by specific examples.
For example, assuming that a two-dimensional code recognition function is integrated in a camera application of the terminal device, when a user needs to perform two-dimensional code recognition, the user may start a camera in the terminal device and start the two-dimensional code recognition function into the camera function, and after the user starts the two-dimensional code recognition function, the terminal device obtains a history recognition record.
Assuming that before the current time, the user successfully performs two-dimensional code scanning for 100 times through the terminal device, and accordingly, the history of two-dimensional code scanning obtained by the terminal device is shown in table 1:
TABLE 1
| Identification of history identification records | Identifying focal distance |
| History identification record 1 | 30 cm |
| History identification record 2 | 31 cm |
| History identification record 3 | 31 cm |
| History identification record 4 | 30 cm |
| …… | …… |
| History identification record 100 | 31 cm |
And then, the preset focal length sections in the terminal equipment are assumed to be 25-27 cm, 27.1-29 cm, 29.1-31 cm, 31.1-33 cm and 33.1-35 cm.
The terminal equipment determines the identification focal length corresponding to each historical identification record, and counts the identification focal length number corresponding to each focal length, and it is assumed that the identification focal length number corresponding to each preset focal length and the identification focal length corresponding to each preset focal length are shown in table 2:
TABLE 2
| Focal length segment | Number of corresponding identification focal lengths | Identifying focal distance |
| 25-27 cm | 2 | 26 cm |
| 27.1-29 cm | 3 | 28 cm |
| 29.1-31 cm | 75 | 30 cm |
| 31.1-33 cm | 15 | 32 cm |
| 33.1-35 cm | 5 | 34 cm |
Assuming that N is 2, from the data shown in table 2, 2 identified focal lengths can be determined to be 30 centimeters and 32 centimeters.
When two-dimensional code recognition is carried out, firstly, two-dimensional code recognition is carried out according to a focal length of 30 cm, if the two-dimensional code cannot be successfully recognized according to the focal length of 30 cm, the two-dimensional code recognition is carried out through a focal length of 32 cm, and if the two-dimensional code cannot be successfully recognized according to the focal length of 32 cm, the two-dimensional code is recognized through an automatic focusing mode.
In the practical application process, according to the data counted in table 2, the user usually recognizes the two-dimensional code with a focal length of 30 cm, and the success rate of recognizing the two-dimensional code through the focal length of 30 cm is high, so that the user can recognize the two-dimensional code successfully through the focal length of 30 cm under the condition that the habit of the user is not changed, and the efficiency of recognizing the two-dimensional code can be improved.
