[0057] Figure 1 A schematic flow chart of a method for benchmarking images taken by a camera according to one aspect of the present application is shown, the method comprising: S100 to S400, wherein in S100, the module parameters required for the camera to take images are obtained, and the preset benchmark image in the material library is called based on the module parameters; in S200, the current imaging corresponding to the benchmark in the camera's viewfinder is obtained, and it is determined whether the preset benchmark image is consistent with the current imaging, and the judgment result is determined; in S300, the position adjustment parameters are determined based on the judgment result, and the position of the camera is adjusted according to the position adjustment parameters; in S400, the shooting of the benchmark is completed. Thereby, the automatic collection of test images in the research and development stage of smart devices is realized, the complexity of camera resolution benchmarking is simplified, and the time cost and labor cost are optimized.

[0058] Specifically, in S100, the module parameters required for the camera to capture images are obtained, and the preset benchmark images in the material library are called based on the module parameters. Here, the application scenario of the present application can be to use cameras with a variety of different parameters in an optical laboratory for resolution benchmark analysis. First, the module parameters required for the camera to capture images are obtained, and the preset benchmark images in the material library are matched based on the module parameters, and the preset benchmark images that are successfully matched are called. Among them, the preset benchmark image is obtained by actual shooting and benchmarking based on a specified distance, a specified angle, and a specified chart.

[0059] In S200, the current imaging corresponding to the reference image in the camera's viewfinder is obtained, and it is determined whether the preset reference image is consistent with the current imaging, and the judgment result is determined. Here, the TVLINE chart image that has been set for the camera reference can be used to obtain the current imaging in the viewfinder. The TVLINE chart image is a subjective judgment image of the resolution, and various image parameters in the current imaging are obtained in real time. The various image parameters in the preset reference image are compared with the various image parameters in the current imaging one by one to determine whether the two are consistent. If not, it indicates that the camera has not reached the specified distance and / or specified angle, and the position of the camera needs to be further adjusted, wherein the position includes but is not limited to the distance between the camera and the chart and the angle between the camera and the horizontal plane.

[0060] In S300, a position adjustment parameter is determined based on the judgment result, and the position of the camera is adjusted according to the position adjustment parameter. Here, when the preset reference image is consistent with the current imaging, the position and / or angle of the camera may not be adjusted, and the position adjustment parameter may be zero; when the preset reference image is inconsistent with the current imaging, the position adjustment parameter is calculated and determined according to the image parameter of the preset reference image, and the position of the camera is adjusted according to the position adjustment parameter so that its imaging is consistent with the preset reference image.

[0061] In S400, the photographing of the target is completed. Here, a camera can be used to complete the photographing of the target, and the performance of the camera can be manually determined based on the photographed image.

Here, the module parameters include but are not limited to module pixels, fixed focus module, focus module and module type, wherein the module types include telephoto, wide angle and macro. Based on the module pixels, fixed focus module, focus module and module type, the corresponding preset reference images are matched in the material library, and the camera resolution is accurately determined by shooting three positions of the same TVLINE chart.

[0063] In an optional embodiment of the present application, in S200, the image parameters corresponding to the preset reference image are compared with the image parameters corresponding to the current imaging to determine whether the two are consistent. If so, the preset reference image is consistent with the current imaging; if not, the preset reference image is different from the current imaging. Here, analyzing whether the image parameters corresponding to the preset reference image are consistent with the image parameters corresponding to the current imaging to determine whether the two are consistent simplifies the calculation process and effectively reduces the amount of calculation.

For example, the target image area in the current imaging can be identified through a frame capture method, and the image parameters of the target image area can be obtained. Then, it is determined whether the image parameters of the target image area are consistent with the image parameters of the corresponding image area in the preset reference image. If so, it is determined that the current imaging is the same as the preset reference image; if not, the current imaging is different from the preset reference image. In this regard, the calculation process can be further effectively simplified and the amount of calculation can be reduced.

[0065] In an optional embodiment of the present application, in S300, when the preset reference image is consistent with the current imaging, the adjustment parameters are all zero; when the preset reference image is different from the current imaging, the position adjustment parameters of the camera are calculated according to the preset reference image. Here, when the preset reference image is consistent with the current imaging, it indicates that the camera does not need to adjust its position, and the adjustment parameters are all zero; when the preset reference image is different from the current imaging, the position adjustment parameters of the camera are calculated according to the preset reference image using a preset algorithm, such as the displacement required by the camera in the coordinate system and the adjustment angle required by the camera.

[0066] In an optional embodiment of the present application, the position of the camera includes the distance between the camera and the reference, the distance between the camera and the ground, and the angle between the camera and the coordinate system. Here, the position adjustment parameters of the camera including the distance between the camera and the reference, the distance between the camera and the ground, and the angle between the camera and the coordinate system are calculated based on the preset reference image using a preset algorithm, thereby realizing the automation of the shooting reference processing before the camera resolution analysis.

Here, the camera is moved to a corresponding shooting distance in the slide rail by the circuit-driven bracket; the camera is raised or lowered to a corresponding shooting height by the circuit-driven bracket; and the angle of the camera in the three directions of the x-axis, y-axis, and z-axis is adjusted by the circuit-driven stabilizer to meet the shooting angle of view.

[0068] In an optional embodiment of the present application, in S100, the preset reference images corresponding to the first position, the second position and the third position in the material library are called based on the module parameters, the current imaging corresponding to the reference in the viewfinder when the camera is respectively at the first position, the second position and the third position is obtained, and it is determined whether the preset reference image corresponding to each position is consistent with the current imaging at the corresponding position, and the judgment result is determined. Here, the application environment of the present application can be an optical laboratory, by setting the camera at at least three positions to shoot the TVLINE chart to obtain experimental data related to the resolution of all cameras, calling the preset reference images corresponding to multiple positions in the material library based on the module parameters, obtaining the current imaging corresponding to the reference in the real-time viewfinder when the camera is respectively at different positions, and then judging whether the current imaging is consistent with the preset reference image at the specified position, if not, the position adjustment parameters of the camera are determined by calculation, and the position adjustment of the camera is completed to complete the shooting of the corresponding position; for example, the first position, the second position and the third position are respectively the left, middle and right positions, and the corresponding module pixels, fixed focus, or focus module and module type are set to call the corresponding left, middle and right three images in the material library. By presetting the preset benchmark images at multiple positions in the library, the camera can be automatically adjusted to the corresponding position to complete the shooting of the specified TVLINE chart, realizing the automation of the shooting benchmarking process of different positions of the same specified image before the camera resolution analysis. By comparing the TVLINE library, angle adjustment prompts and automatic capture can be realized. The use of slide rails and bracket lifting can quickly align, with excellent stability, reducing the failure of manual alignment and shooting offset caused by hand shaking, and improving shooting efficiency.

Then, a new current image is input, and the new current image is compared with the current template to calculate the difference of the image parameters. Based on the difference of the image parameters, the distance and angle that the camera needs to move are fed back, and then the secondary alignment of the camera is completed. At this time, it is determined whether the new current imaging is consistent with the current template. If so, take a photo; if not, repeat the comparison of the image difference between the new current image and the current template and adjust the position of the camera. By automatically adjusting the camera to the corresponding position to complete the shooting of the specified TVLINE chart, the automation of the shooting alignment processing of different positions of the same specified image before the camera resolution analysis is realized.
