An exemplary embodiment of the present disclosure provides an identification method of an identification code, as shown in fig. 1, fig. 1 is a flowchart of an identification method of an identification code according to an exemplary embodiment, the identification method of an identification code is applied to a terminal device, the terminal device includes a plurality of camera modules, and as shown in fig. 1, the identification method of an identification code includes the steps of:
step S101: receiving a scanning instruction of a camera module of a preset application calling terminal device for scanning;
step S102: acquiring a first target image of a preset target through a first camera module;

step S104: if not, based on the recognition failure reason, switching to a second camera module, acquiring a second target image of the preset target through the second camera module, and recognizing the recognition code in the second target image.
According to the identification method of the identification code, which is provided by the exemplary embodiment of the disclosure, after a scanning instruction of a preset application for calling a camera module of the terminal equipment to scan is received, a first camera module of the terminal equipment is called to acquire a first target image of a preset target, whether the identification code is identified in the first target image is determined, if the identification code is not identified, the identification code is switched to a second camera module of the terminal equipment based on the reason of identification failure, and the second target image is acquired through the second camera module to identify the identification code. In the identification method of the identification code provided by the exemplary embodiment of the disclosure, the characteristic that the terminal equipment comprises a plurality of camera modules is utilized, the plurality of camera modules are used for identifying the identification code under different conditions, and after the user fails to scan the identification code by using the first camera module, the identification code can be automatically switched to the second camera module for identification according to the identification failure reason, so that the identification success rate of the identification code is improved, and the user experience is improved.
In step S101, a scan instruction for invoking a camera module of a terminal device to scan by a preset application is received.
The scanning instruction of receiving the preset application and calling the camera module of the terminal equipment to scan can be a code scanning payment instruction in mobile payment software such as WeChat, payment treasury and the like, or a code scanning riding instruction such as dripping, beauty team and the like, and can call the camera module of the terminal equipment through the scanning instruction similar to the scanning instruction of scanning once as long as the application software can acquire the authority of the camera module of the terminal equipment. The camera module of the terminal equipment is used for scanning the identification code, and the identification code can be a two-dimensional code or any other identification code which can be identified.
In step S102, a first target image of a preset target is acquired through a first camera module.
After receiving the scanning instruction, starting the first camera module, and acquiring a first target image of a preset target through the first camera module. The first camera module of the terminal device may be a main camera module of a camera module of the terminal device, which is a main common camera module of the terminal device. The main camera module is started, for example, the configuration of a register controlling the start of the main camera module is written into the main camera module, for example, the relevant configuration of stream on of a corresponding register is written into the main camera module, so as to start the main camera module. The terminal device may include a register for controlling the start of the main camera module only, so as to control the start of the main camera module separately. After the main camera module is started, acquiring image data of a preset target, and displaying a first target image corresponding to the preset target acquired by the main camera module on a preview interface of a preset application. The preset target may be an identification code, and the first target image of the preset target is obtained through the camera module of the terminal device, that is, the first camera module can obtain an image of a shooting area corresponding to the identification code.
In step S103, it is determined whether an identification code is identified in the first target image.
After the first target image is acquired, whether the identification code can be identified in the acquired first target image can be detected, if the identification code can be identified in the first target image, the identification code analysis is completed, and the identification code identification method is ended. If the identification code cannot be identified in the first target image, determining the reason of the identification failure, and correspondingly switching to the corresponding camera module according to the reason of the identification failure.
In step S104, if not, based on the failure recognition reason, the camera is switched to the second camera module, and the second camera module obtains the second target image of the preset target, so as to recognize the identification code in the second target image.
If the first target image has no identifiable identification code, indicating that the identification fails, switching the camera module to a second camera module of the terminal equipment through the reason of the identification failure, acquiring a second target image of a preset target through the second camera module, and identifying the second target image. When switching to the second camera module of the terminal equipment, writing the configuration of the register started by the controller into the second camera module. For example, the relevant configuration of stream on of the corresponding register is written into the second camera module to start the second camera module. The terminal device may include a register for controlling the start of the second camera module only, so as to separately control the start of the second camera module. After the second camera module is started, acquiring image data of a preset target, displaying a second target image corresponding to the preset target acquired by the second camera module on a preview interface of a preset application, and re-identifying an identification code in the image. The second camera module can be a long focus camera module, a wide angle camera module, a micro-distance camera module, a black-and-white camera module and the like.
In an exemplary embodiment of the disclosure, after a scan instruction of a preset application for calling a camera module of a terminal device to scan is received, a first camera module of the terminal device is called to acquire a first target image of a preset target, if an identification code is not identified in the first target image, based on a reason of identification failure, a second camera module of the terminal device is switched to acquire a second target image of the preset target again and identify the identification code in the second target image, so that after the user fails to identify the identification code by using the first camera module, other camera modules are automatically switched to acquire images, the identification success rate of the identification code is improved, and user experience is improved.
In an exemplary embodiment of the present disclosure, switching to the second camera module based on the identification failure cause includes:
when the identification failure reason is that the area occupation ratio of the area where the identification code is located in the first target image is smaller than a first preset threshold value, switching to a tele camera module of the terminal equipment;
when the identification failure reasons are that the area where the identification code is located comprises part of the identification code, switching to a wide-angle camera module of the terminal equipment;
when the identification failure reason is that the area ratio of the area where the identification code is located in the first target image is larger than a second preset threshold value, switching to a micro-distance camera module of the terminal equipment;
and when the reason of the identification failure is that the noise in the area where the identification code is located is larger than a preset noise threshold value, switching to a black-and-white camera module of the terminal equipment.
If the identification code in the first target image acquired by the first camera module of the terminal equipment fails to be identified, namely the identification code is not identified in the first target image acquired by the first camera module, determining the reason of the identification failure, switching the reason to the second camera module of the terminal equipment according to the identification failure reason, acquiring the second target image of the preset target by the second camera module, identifying the identification code in the second target image, and completing the identification of the identification code. In the exemplary embodiment of the disclosure, when the identification code of the first target image acquired by the first camera module fails to identify, the second camera module is automatically switched to the second camera module based on the reason of the identification failure so as to realize the identification code identification, so that manual operation of a user is not needed, and user experience is improved.
When the reason of the identification failure is that the area ratio of the area where the identification code is located in the first target image is smaller than a first preset threshold, and the first preset threshold is the minimum area ratio of the area where the identification code is located in the first target image just capable of identifying the identification code, the obtained area where the identification code is located is very small relative to the whole shooting area of the first shooting module, which is caused by the fact that the terminal equipment is too far away from the identification code, if the identification code fails, the identification code can be switched to the tele shooting module of the terminal equipment, and the second target image is obtained for identification code identification after the preset target is amplified.
When the cause of the recognition failure is that the area where the identification code is located includes a part of the identification code, for example, when the aspect ratio of the identifiable part of the identification code is different from the standard aspect ratio. The difference is caused by the fact that the area where the identification code is located at the edge of the shooting area of the first shooting module. The first shooting module is limited by the shooting area, so that the identification code in the first target image is cut to be incomplete, the wide-angle shooting module of the terminal equipment or the ultra-wide-angle shooting module can be switched at the moment, the shooting area is enlarged, the second target image is acquired, the whole identification code can be displayed in the second target image, and the identification code identification is carried out on the second target image.
When the reason of the recognition failure is that the area ratio of the area where the recognition code is located in the first target image is larger than the second preset threshold, the second preset threshold is that the largest area ratio of the area where the recognition code is located in the first target image can be just displayed in the first target image and the recognition code can be recognized, and the obtained area where the recognition code is located is quite large compared with the whole shooting area of the first shooting module, because the distance between the terminal equipment and the recognition code is smaller than the focusing distance of the first shooting module, focusing cannot be performed, and if the recognition code fails, the second target image shot at a short distance can be obtained by switching to the micro-distance shooting module of the terminal equipment at the moment for recognition.
When the recognition failure causes that the noise in the area where the recognition code is located is larger than a preset noise threshold value, the preset noise threshold value is the maximum noise value when the recognition code can be just recognized. The noise can comprise image color noise, and the recognition code fails to recognize due to the fact that the color noise of the area where the recognition code is located is large, at the moment, the black-and-white camera module of the terminal equipment can be switched, the contrast of a preset target is enhanced, and a second target image is acquired for recognition.
The reason for failure in recognition of the identification code is determined through the characteristics of the area where the identification code is located, and the corresponding second camera module is switched according to the reason for failure in recognition, so that the preset target can be further recognized, and the success rate of recognition of the identification code is improved.
In an exemplary embodiment of the present disclosure, the second camera module is powered on after receiving the scan instruction.
After receiving the scanning instruction, namely after receiving the scanning instruction of calling the camera module of the terminal equipment by the preset application to scan, powering up the first camera module of the terminal equipment and powering up the second camera module. And calling the first camera module to acquire a first target image, wherein the second camera module is in a power-on state at the moment and can be called at any time. The power-on means that the camera module is electrified and is in a state of being called at any time. When the first camera module fails to accurately identify the identification code after the second camera module is electrified, the second camera module can be called at any time, so that the second camera module can acquire a second target image corresponding to a preset target to identify the identification code. When the second camera module is in a power-on state, the second camera module is not called, so that the use power is small, the running state of the terminal equipment is not influenced, the power consumption of the terminal equipment is not influenced, the second camera module can be called at any time, the flexibility of identification code identification is improved, and the power consumption of the terminal equipment is not increased.
In an exemplary embodiment of the present disclosure, the first camera module is turned off after switching to the second camera module.
The first target image acquired by the first camera module fails to identify the identification code, the first target image is switched to the second target image continuously acquired by the second camera module, the second camera module is started, and the first camera module can be closed in order to reduce the power consumption of the terminal equipment. The second camera module is started to write the relevant configuration of the stream on of the corresponding register into the second camera module, and simultaneously write the relevant configuration of the stream off of the corresponding register into the first camera module to close the first camera module. In the identification process of the identification code provided by the exemplary embodiment of the disclosure, although the identification code is identified by utilizing the plurality of camera modules of the terminal equipment, only one camera module of the terminal equipment is started at the same time, so that the power consumption of the terminal equipment is not increased, and the user experience is increased.
In a disclosed exemplary embodiment, before acquiring a first target image of a preset target by a first camera module, the method includes: determining whether the area where the identification code is located is stable.
When a user scans the identification code by using a preset application of the terminal equipment, the situation that the area where the identification code is located is unstable can occur due to some uncertainty factors. At this time, when the identification code is identified, the identification failure is easy to occur, and meanwhile, the reason of the identification failure is determined inaccurately, so that before the first target image of the preset target is acquired through the first camera module, whether the area where the identification code is located is stable is determined.
As shown in fig. 2, fig. 2 is a flowchart illustrating a determination of whether an area where an identification code is located in a first target image is stable, and as shown in fig. 2, the determination of whether the area where the identification code is located is stable includes the following steps:
step S201: acquiring a preset number of images within a preset time length, and determining a difference value between the positions of the areas where the identification codes are located in any two frames of images;
step S202: and when all the difference values are in the preset range, determining that the area where the identification code is located is stable.
Acquiring a preset number of images within a preset time length, determining a difference value between the positions of the areas where the identification codes are located in any two frames of images, and determining that the areas where the identification codes are located are stable when all the difference values are within a preset range, so that a first target image can be acquired. Judging whether the area where the identification code is located is stable or not can further improve the success rate of identification of the identification code.
In step S201, a preset number of images are acquired within a preset time period, and a difference value between positions of areas where identification codes in any two frames of images are located is determined.
The method for identifying the area where the identification code is located may be any method capable of identifying the area where the identification code is located in the image by, for example, identifying the area where the identification code is located in the image by a learning model, such as a convolutional neural network identification model, determining the relative position of the area where the identification code is located in the image, and calculating the difference value of the relative position of the area where the identification code is located in any two frames of images.
In step S202, when all the difference values are within the preset range, it is determined that the area where the identification code is located is stable.
When the difference value of the relative positions of the areas where the identification codes are located in any two frames of images is within a preset range, the positions of the areas where the identification codes are located in the images are relatively stable, and a first target image can be obtained.
In an exemplary embodiment of the present disclosure, when the second camera module needs to be switched to further identify the identification code, the user may be prompted whether to switch to the second camera module. For example in the form of a pop-up window to prompt the user if a handover is required.
When the terminal equipment is switched to the second camera module, if the position of the terminal equipment needs to be adjusted so that the second camera module accurately acquires the identification code, a user can be prompted to adjust a mode, for example, a popup window mode is used for prompting the user of the position needing to be moved, so that the second camera module accurately scans the identification code. For example, after the second camera module is switched to, the preset target, namely the area where the identification code is located, cannot be located in the shooting area of the second camera module, and the terminal equipment pops up prompt information to prompt a user to adjust the position of the terminal equipment to sweep the code, so that the identification success rate of the identification code is improved, and the user experience is improved.
In an exemplary embodiment of the disclosure, determining whether the second camera module exists in the terminal device, and if not, prompting a user to adjust the position of the terminal device to identify the identification code.
And when the identification code is not identified in the first target image acquired through the first camera module, determining the type of the second camera module to be switched according to the identification failure reason. Before determining to switch to the second camera module, determining whether the second camera module of the type exists in the terminal equipment, and if so, directly switching to the second camera module; if the second camera module of the type does not exist, prompting the user to adjust the position of the terminal equipment to scan the code again. For example, a user is prompted in a popup window mode to need a code scanning position of the mobile terminal device, so that the first camera module can acquire a first target image of a preset target again.
According to the identification method of the identification code, which is provided by the exemplary embodiment of the disclosure, after a scanning instruction of a preset application for calling a camera module of the terminal equipment to scan is received, a first camera module of the terminal equipment is called to acquire a first target image of a preset target, whether the identification code is identified in the first target image is determined, if the identification code is not identified, the identification code is switched to a second camera module of the terminal equipment based on the reason of identification failure, and a second target image of the preset target is acquired through the second camera module so as to identify the identification code in the second target image. The failure cause is automatically analyzed and the corresponding camera module is automatically switched, so that the success rate of identification of the terminal equipment to the identification code can be improved, the user can use the identification code to identify the function more conveniently and efficiently, and the user experience is improved.
