[0046] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0047] Figure 1 An optional system structure of a motion capture camera evaluation system for implementing camera parameter evaluation provided in an embodiment of the present application is as follows: Figure 1 As shown, the system structure may include: 1. Control module. The control module may include a controller, a servo drive and a power supply. 2. Drive motor. 3. Guide rail. 4. Guide rail fixing device. 5. Guide rail fixing device. 6. Object to be captured. The object to be captured 6 may include a slide, a hollow plate and an object fixed on the hollow plate (such as a photo and a color card). 7. Marquee. Shooting module. The shooting module may include a test machine 8, a clicker 9, a click controller 10 and a bracket. 11. Auxiliary analysis module. The auxiliary analysis module 11 may include an auxiliary machine and an analysis module.

[0048] Specifically, the ticker 7 can be used to display the timing time for video recording. The bracket can support the test machine 8. The test machine 8 can be used to capture the captured object 6. The clicker 9 can click the screen of the test machine 8. The click controller 10 can control the clicker 9 to click.

[0049] Further, after starting the control module 1, the captured object 6 can be driven by the controller to make a reciprocating motion on the guide rail 3. The shooting field of the shooting module can include the marquee 7, the guide rail 3, and the captured object 6, so as to capture the captured object 6 in the process of making a reciprocating motion.

[0050] Furthermore, the auxiliary machine can record the test machine 8, and the recording field of the auxiliary machine includes the test machine 8, the screen display content of the test machine 8, the clicker 9, the marquee 7, the guide rail 3 and the captured object 6.

[0051] It is understandable that both the test machine 8 and the auxiliary machine are equipped with built-in cameras, and the purpose of the system design is to analyze the parameter response time of the test machine camera through the auxiliary machine.

[0052] During the specific operation, the slow motion mode (240fps) of the auxiliary machine can be used to record the video, and at the same time, the click controller 10 can be used to control the clicker 9 to start clicking and taking pictures, so as to replace manual clicking.

[0053] based on Figure 1 The system structure shown in Figure 2 An optional signaling process of the auxiliary analysis module 11 implementing the camera parameter evaluation method provided in the embodiment of the present application is shown, referring to Figure 2 , the process may include:

[0054] Step S110: After the test machine takes a preset number of photos, the recorded video of the auxiliary machine is obtained.

[0055] Specifically, the test machine 8 can capture the captured object 6 multiple times, such as 10 times, to obtain 10 captured photos, and the process of the test machine 8 capturing 10 times is recorded by the auxiliary machine to obtain a recorded video.

[0056] Step S120: For each photo taken by the test machine in the recorded video, record the first time indicated by the marquee when the test machine performs a parameter evaluation action on the photo, and the second time indicated by the marquee when responding to the parameter evaluation action, and determine the difference between the second time and the first time as the response time of the test machine performing the parameter evaluation action on the photo.

[0057] It can be understood that the response time of each parameter of the camera can be expressed as the time from the start of the evaluation action of the parameter to the end of the evaluation action of the parameter. Therefore, the first time when the parameter evaluation action starts and the second time when the parameter evaluation action ends can be recorded, and then the difference between the two times can be calculated to obtain the response time of the test machine performing the parameter evaluation action on the photo.

[0058] Step S130: taking the average value of the response time of the test machine performing the parameter evaluation action on each photo as the evaluation result of the parameter evaluation action of the test machine.

[0059] It is understandable that there may be deviations in the parameter evaluation action between each snapshot by the test machine 8. Therefore, the corresponding multiple response times obtained after multiple snapshots can be averaged to obtain the evaluation results of the parameter evaluation action of the test machine, making the evaluation results of the camera parameters more reliable.

[0060] The camera parameter evaluation method provided in this embodiment is designed to make the captured object move back and forth on the guide rail, and use a ticker to indicate the time, the test machine captures the captured object and the ticker, the auxiliary machine records the test machine and the recording content includes a clicker for clicking the test machine screen, and further, after the test machine takes a preset number of photos, the recording video of the auxiliary machine is obtained, and for each photo taken by the test machine in the recorded video, the first time indicated by the ticker when the test machine performs the parameter evaluation action on the photo, and the second time indicated by the ticker when responding to the parameter evaluation action are recorded, and the difference between the second time and the first time is determined as the response time of the test machine to perform the parameter evaluation action on the photo, and the average value of the response time of the test machine to perform the parameter evaluation action on each photo is used as the evaluation result of the parameter evaluation action of the test machine. It can be seen that the test action is completed by clicking the clicker, and there is no need to click manually. The response time of each camera parameter can be defined according to the ticker in the recorded video, so that the camera parameters obtained by the evaluation are more reliable, thereby improving the overall quality and efficiency of the camera test link of the mobile terminal device.

[0061] In some embodiments of the present application, for the above step S120, for each photo taken by the test machine in the recorded video, recording the first time indicated by the ticker when the test machine performs a parameter evaluation action on the photo, and the second time indicated by the ticker when responding to the parameter evaluation action, and determining the difference between the second time and the first time as the response time of the test machine performing the parameter evaluation action on the photo is introduced. The process may include:

[0062] For each photo taken by the test machine in the recorded video, record the first time indicated by the marquee when the test machine opens the photo, and record the second time indicated by the marquee when the clicker clicks the screen of the test machine that took the photo, and determine the time delay between the second time and the first time as the shutter delay for the test machine to take the photo.

[0063] When the clicker clicks on the screen of the test machine, a blue indicator light will light up to indicate the click effect.

[0064] Specifically, the shutter delay can be expressed as the time from opening the photo to clicking to shoot. Therefore, the time T1 of the ticker can be recorded when the photo is opened, and the time T2 of the ticker can be recorded when the clicker is clicked, so that T2-T1 is the shutter delay for the test machine to take the photo.

[0065] Furthermore, after the shutter delays are obtained by similarly processing the remaining photos, the shutter delays can be averaged to obtain the shutter delay parameter evaluation result of the test machine.

[0066] In some embodiments of the present application, for the above step S120, for each photo taken by the test machine in the recorded video, recording the first time indicated by the ticker when the test machine performs a parameter evaluation action on the photo, and the second time indicated by the ticker when responding to the parameter evaluation action, and determining the difference between the second time and the first time as the response time of the test machine performing the parameter evaluation action on the photo is introduced. The process may include:

[0067] For each photo taken by the test machine in the recorded video, record the first time indicated by the marquee when the camera preview interface of the test machine starts to freeze after the test machine takes the photo, and record the second time indicated by the marquee when the camera preview interface is restored, and determine the time delay between the second time and the first time as the preview freeze time of the photo taken by the test machine.

[0068] Specifically, the preview freeze time can be expressed as the time from when the camera preview interface starts to freeze after each photo is taken to when the camera preview interface is restored. Therefore, when the camera preview interface of the test machine starts to freeze, the time T1 of the marquee can be recorded, and when the camera preview interface is restored, the time T2 of the marquee can be recorded, so that T2-T1 is the preview freeze time of the photo taken by the test machine.

[0069] Furthermore, after the preview freeze time is obtained by processing the remaining photos in the same manner, the average of the preview freeze time can be taken to obtain the preview freeze time parameter evaluation result of the test machine.

[0070] In some embodiments of the present application, for the above step S120, for each photo taken by the test machine in the recorded video, recording the first time indicated by the ticker when the test machine performs a parameter evaluation action on the photo, and the second time indicated by the ticker when responding to the parameter evaluation action, and determining the difference between the second time and the first time as the response time of the test machine performing the parameter evaluation action on the photo is introduced. The process may include:

[0071] For each photo taken by the test machine in the recorded video, record the first time indicated by the marquee when the clicker clicks the screen of the test machine to make the test machine take the photo, and record the second time indicated by the marquee when the camera preview interface of the test machine begins to freeze, and determine the time delay between the second time and the first time as the preview response time for the test machine to take the photo.

[0072] When the clicker clicks on the screen of the test machine, a blue indicator light will light up to indicate the click effect.

[0073] Specifically, the preview response time can be expressed as the time from the clicker clicking the screen of the test machine to the time when the camera preview interface starts to freeze. Therefore, when the clicker clicks the screen of the test machine, the time T1 of the marquee can be recorded, and when the camera preview interface starts to freeze, the time T2 of the marquee can be recorded, so that T2-T1 is the preview response time for the test machine to take the photo.

[0074] Furthermore, after the preview response times of the remaining photos are processed in the same manner, the average of the preview response times of the respective photos can be taken to obtain the preview response time parameter evaluation result of the test machine.

[0075] In some embodiments of the present application, for the above step S120, for each photo taken by the test machine in the recorded video, recording the first time indicated by the ticker when the test machine performs a parameter evaluation action on the photo, and the second time indicated by the ticker when responding to the parameter evaluation action, and determining the difference between the second time and the first time as the response time of the test machine performing the parameter evaluation action on the photo is introduced. The process may include:

[0076] For each photo taken by the test machine in the recorded video, record the first time when the clicker clicks the screen of the test machine to indicate when the test machine takes the photo, and record the second time indicated by the marquee when the thumbnail on the screen of the test machine is animated, and determine the time delay between the second time and the first time as the thumbnail generation time when the test machine takes the photo.

[0077] When the clicker clicks on the screen of the test machine, a blue indicator light will light up to indicate the click effect.

[0078] Specifically, the thumbnail generation time can be expressed as the time from when the clicker clicks the screen of the test machine until the thumbnail appears in motion on the screen of the test machine. Therefore, when the clicker clicks the screen of the test machine, the time T1 of the marquee can be recorded, and when the thumbnail appears in motion on the screen of the test machine, the time T2 of the marquee can be recorded, so that T2-T1 is the thumbnail generation time of the photo taken by the test machine.

[0079] Furthermore, after the thumbnail generation time is obtained by similarly processing the remaining photos, the average of the thumbnail generation times can be taken to obtain the thumbnail generation time parameter evaluation result of the test machine.
