Description

An evaluation system, method and device for frame rate dynamic adjustment performance

technical field

The embodiments of the present application relate to the field of electronic equipment, and in particular to an evaluation system, method and device for dynamically adjusting frame rate performance.

Background technique

The electronic device shoots video at a certain frame rate (Frame Rate), that is, the electronic device shoots images of a specified number of frames within one second. Video captured by the electronic device will also be played at the frame rate used to capture it. For the same frame rate, other parameters when the electronic device shoots the video will also affect the playback effect of the video. For example: Electronic devices shoot video at the same frame rate. If the background brightness of the object to be shot is low, the playback effect of the video will be stuck. Video playback is smoother.

In order to improve the playback effect of the video, the electronic device uses a dynamic frame rate to shoot the video, that is, the electronic device dynamically adjusts the frame rate used according to the preset frame rate adjustment rule and according to the change of the environmental parameters. For example: if the background brightness of the object to be photographed is low when photographing, the electronic device uses a higher frame rate for photographing. If the background brightness of the object to be photographed is relatively high when photographing, the electronic device uses a lower frame rate for photographing.

When electronic equipment dynamically adjusts the frame rate, it may be limited by its own computing power and device reasons, resulting in frame loss and unsmooth frame rate switching, which in turn leads to video frame loss and frame skipping. It can be seen that the dynamic adjustment performance of the frame rate of the electronic device will directly affect the video shooting performance of the electronic device. Thus, the video shooting performance of the electronic device can be evaluated according to the dynamic adjustment performance of the frame rate of the electronic device. However, the existing system for evaluating the dynamic adjustment performance of the frame rate of the electronic device cannot accurately simulate various shooting scenarios of the electronic device, resulting in the inability to accurately determine the dynamic adjustment effect of the electronic device on the frame rate in various shooting scenarios, and then It is impossible to accurately evaluate the frame rate dynamic adjustment performance of electronic equipment.

The terms used in the embodiments of the present application are only used to explain the specific embodiments of the present application, and are not intended to limit the present application. The embodiments of the present application will be described in detail below with reference to the accompanying drawings.

When the electronic device uses a dynamic frame rate to shoot video, the electronic device dynamically adjusts the used frame rate according to the preset frame rate adjustment rule and according to the change of the environmental parameters. Taking a mobile phone as an example, if the frame rate adjustment rule of the mobile phone is when the ambient brightness is greater than 100Lux, the frame rate used by the mobile phone is 60FPS. When the ambient brightness is less than or equal to 100Lux, the frame rate used by the mobile phone is 30FPS. Therefore, it is assumed that the mobile phone detects that the ambient brightness is 110Lux during the video shooting process, and the mobile phone uses 60FPS to shoot. If the mobile phone detects that the ambient brightness has changed to 80Lux, the mobile phone will switch to 30FPS for shooting. However, when the electronic device dynamically adjusts the frame rate, it may be limited by its own computing power and device reasons, resulting in frame loss and unsmooth frame rate switching, which in turn leads to video frame loss and frame skipping. It can be seen that the dynamic adjustment performance of the frame rate of the electronic device will directly affect the video shooting performance of the electronic device. Thus, the video shooting performance of the electronic device can be evaluated according to the dynamic adjustment performance of the frame rate of the electronic device. However, the existing system for evaluating the dynamic adjustment performance of the frame rate of the electronic device cannot accurately simulate various shooting scenarios of the electronic device, resulting in the inability to accurately determine the dynamic adjustment effect of the electronic device on the frame rate in various shooting scenarios, and then It is impossible to accurately evaluate the frame rate dynamic adjustment performance of electronic equipment.

Step S601 , during the process of the device to be evaluated 11 shooting the target object, adjust the parameters of the scene simulation device to switch the shooting scene when the device to be evaluated 11 shoots the target object.

Before the device to be evaluated 11 shoots the target object 12, firstly, the shooting preparation work is carried out. The shooting preparation work includes: adjusting the shooting distance and shooting angle between the device to be evaluated 11 and the target object 12, so that the device to be evaluated 11 focuses on the target on the object 12, and make the target object 12 completely located within the viewfinder frame of the device to be evaluated 11. Wherein, the target object 12 is completely located within the viewfinder frame of the device to be evaluated 11 means: when the target object 12 moves and/or the device to be evaluated 11 moves, the target object 12 can be completely located within the viewfinder frame of the device to be evaluated 11 .

In one implementation manner, the device to be evaluated 11 is manually controlled to start photographing the target object 12 and to end the photographing of the target object 12 . In another implementation manner, the terminal device 14 may control the device to be evaluated 11 to start photographing the target object 12 and stop photographing the target object 12 . The terminal device 14 controls the device to be evaluated 11 to photograph the target object 12, which may be realized through a trigger. The trigger is used to trigger the photographing button of the device to be evaluated 11 under the control of the terminal device 14 instead of a human hand, so that the device to be evaluated 11 starts to photograph the object 12 and ends to photograph the object 12 . With reference to the evaluation system shown in FIG. 7 , a trigger 15 is set on the device to be evaluated 11 so that the trigger 15 can trigger the shooting button of the device to be evaluated 11 . The trigger 15 is connected with the terminal device 14 to control the triggering operation of the trigger 15 through the terminal device 14 .

When the device to be evaluated 11 shoots the target object 12, the terminal device 14 controls to turn on the scene simulation device 13, and controls to adjust the parameters of the scene simulation device 13, so as to realize automatic and continuous switching of various shooting scenes.

In one implementation manner, the terminal device 14 controls the scene simulation device 13 to start working after the device to be evaluated 11 starts to photograph the target object 12 . In this implementation manner, the video obtained by shooting the target object 12 by the device to be evaluated 11 includes a first video segment and a second video segment. Wherein, the first video segment is a video segment shot by the device to be evaluated 11 in a default shooting environment before the scene simulation device 13 constructs a shooting scene, that is, before the terminal device 14 controls the scene simulation device 13 to start adjusting parameters. After the device to be evaluated 11 starts to shoot the target object 12, it shoots at a corresponding frame rate according to a default shooting environment to obtain a first video clip. The second video segment is a video segment shot by the device to be evaluated 11 in various shooting scenarios constructed by the scene simulation device 13 . The device to be evaluated 11 monitors the change of the shooting scene, and determines the used frame rate according to the frame rate adjustment rule, uses the determined frame rate to shoot, and obtains the second video segment.

In another implementation, the terminal device 14 controls the device to be evaluated 11 to photograph the target object 12 , and the terminal device 14 controls the device to be evaluated 11 to start photographing the target object 12 while controlling the scene simulation device 13 to start working. In this implementation, the video obtained by the device to be evaluated 11 shooting the target 12 includes a third video clip, and the third video clip is a video clip shot by the device to be evaluated 11 in various shooting scenarios constructed by the scene simulation device 13 . The video does not include video clips shot by the device to be evaluated 11 in a default shooting environment. For example: taking the evaluation system shown in FIG. 7 as an example, the terminal device 14 controls the scene simulation device 13 and the trigger 15 to start simultaneously, so as to control the scene simulation device 13 and the device to be evaluated 11 to start working simultaneously.

The evaluation system 100 is used to evaluate the frame rate dynamic adjustment performance of the device to be evaluated 11. Since the device to be evaluated 11 dynamically adjusts the frame rate according to the corresponding frame rate adjustment rule, the evaluation system 100 needs to evaluate the frame rate adjustment rule of the device to be evaluated 11. The ability to dynamically adjust the frame rate under the shooting scene specified in .

FIG. 8 is a flow chart of a method 800 for the terminal device 14 to adjust the parameters of the scene simulation device 13 provided by the embodiment of the present application. As shown in FIG. 8, the method 800 includes the following steps S801-step S802:

Step S801, acquiring frame rate adjustment rules of the device to be evaluated 11 .

The terminal device 14 may obtain the frame rate adjustment rule used by the device to be evaluated 11 according to the model of the device to be evaluated 11 . For example, the terminal device 11 can obtain the frame rate adjustment rule of the device to be evaluated 11 from the Internet, the cloud, etc. according to the model of the device to be evaluated 11 input by the user. The terminal device 14 may also directly acquire the frame rate adjustment rule of the device to be evaluated 11 according to the pre-stored frame rate adjustment rule. For example: the frame rate adjustment rules of various devices to be evaluated 11 are stored in the terminal device 14 in advance, and the terminal device 14 can determine the frame rate adjustment rules from the pre-stored frame rate adjustment rules according to the model of the device to be evaluated 11 input by the user. A frame rate adjustment rule corresponding to the device 11 to be evaluated.

Step S802, adjusting the parameters of the scene simulation device according to the scene parameters corresponding to each shooting scene.

From the above description of the frame rate adjustment rules, it can be seen that the frame rate adjustment rules of the device to be evaluated 11 include the specified frame rate corresponding to the device to be evaluated 11 in various shooting scenarios, and scene parameters corresponding to each shooting scene. In order to ensure the evaluation integrity of the frame rate dynamic adjustment performance of the device to be evaluated 11, that is, to ensure the ability to dynamically adjust the frame rate of the device to be evaluated 11 in all shooting scenes, the terminal device 14 needs to control the scene simulation device 13 to simulate all preset shooting The scene is to simulate all shooting scenes included in the frame rate adjustment rule of the device 11 to be evaluated. For example: if the frame rate adjustment rule of the device to be evaluated 11 includes shooting scene A and shooting scene B, the terminal device 14 needs to control the scene simulation device 13 to simulate shooting scene A and shooting scene B.

The terminal device 14 adjusts the parameters of the scene simulation device 13 so that the adjusted parameters match the scene parameters of the shooting scene, thereby accurately simulating the corresponding shooting scene in the frame rate adjustment rule. Wherein, the terminal device 14 adjusts at least one parameter of the scene simulation device 13 according to the scene parameters of the shooting scene.

In an implementation manner, the terminal device 14 resets all parameters of the scene simulation device 13 according to the scene parameters of the shooting scene.

In another implementation manner, the terminal device 14 resets parameters among all the parameters of the scene simulation device 13 that are different from the currently used parameters according to the scene parameters of the shooting scene. In this implementation, the shooting scenes in the frame rate adjustment rule are arranged sequentially according to the gradual change of the shooting parameters, and the parameters of the scene simulation device 13 can be adjusted in sequence according to the arrangement order of the shooting scenes in the frame rate adjustment rule, thereby , each time only part of the parameters of the scene simulation device 13 need to be adjusted, so that the time for adjusting the parameters of the scene simulation device 13 can be effectively reduced, so as to improve the continuity of switching scenes.

In some embodiments, the terminal device 14 is respectively connected to each device in the scene simulation device 13 to control and adjust the device parameters of each device in the scene simulation device 13 to achieve the effect of controlling and adjusting the parameters of the scene simulation device 13 . Referring to the evaluation system 100 shown in FIGS. 2-4 , if the scene simulation device 13 includes at least one of the lighting device 131 , the moving device 132 and the vibration device 133 , the terminal device 14 is connected to the lighting device 131 , the moving device 132 and the vibration device 133 respectively. Vibration device 133.

The terminal device 14 adjusts the device parameters of the lighting device 131, the moving device 132 and the vibrating device 133 according to the correspondence between the device parameters of the lighting device 131, the moving device 132 and the vibrating device 133 described above and the scene parameters of the shooting scene. Among them, the terminal device 14 adjusts the vibration parameters of the vibration device 133 according to the motion parameters of the device to be evaluated 11 corresponding to each shooting scene, for example: the terminal device 14 adjusts the vibration parameters of the vibration device 133 according to the motion frequency of the device to be evaluated 11 in the scene parameters. vibration frequency. The terminal device 14 adjusts the vibration amplitude of the vibration device 133 according to the motion amplitude of the device to be evaluated 11 in the scene parameters. The terminal device 14 adjusts the brightness of the lighting device 131 according to the brightness in the lighting parameter of the scene parameter. The terminal device 14 adjusts the color temperature of the lighting device 131 according to the color temperature in the lighting parameter of the scene parameter. The terminal device 14 adjusts the moving speed of the moving device 132 according to the moving speed of the captured object in the scene parameters. The terminal device 14 adjusts the moving direction of the moving device 132 according to the moving direction of the captured object in the scene parameters.

Step S602, acquiring a video of the target object captured by the device to be evaluated 11 .

In one implementation, if the terminal device 14 controls the scene simulation device 13 to start working after the device to be evaluated 11 starts to shoot the target 12 , the video shot by the device to be evaluated 11 includes the first video clip and the second video clip. According to the description of the first video clip and the second video clip in step S601, it can be seen that the first video clip is not a video clip shot in a preset shooting scene and should not participate in the evaluation. Therefore, the first video clip needs to be deleted from the video One video segment, subsequent evaluation is only performed on the second video segment.

The terminal device 14 records the first time point when the device to be evaluated 11 starts shooting, and the second time point when the scene simulation device 13 starts working, and determines the first video segment by calculating the difference between the first time point and the second time point The first time period corresponds to the second time period corresponding to the second video segment, and the video segment corresponding to the first time period is deleted from the video to obtain the second video segment.

In this implementation, if the device to be evaluated 11 has a weak shooting response ability or other auxiliary devices (such as the trigger 15) that cause the delayed shooting of the device to be evaluated 11, you can use the device to be evaluated 11 in the scene The operation of shooting the first video segment before the simulation device 13 starts working, to make up for the delayed shooting, so as to ensure that the starting point of the second video segment captured by the device to be evaluated 11 can accurately correspond to the second time point when the scene simulation device 13 starts working , so as to ensure the accuracy of the subsequent evaluation.

In another implementation, if the terminal device 14 controls the device to be evaluated 11 to shoot the target object 12, the terminal device 14 controls the device to be evaluated 11 to start shooting the target object 12 while controlling the scene simulation device 13 to start working. The video captured by device 11 only includes the third video segment. According to the description of the third video clip in step S601, it can be seen that all the third video clips are valid video clips and can be directly used for subsequent evaluation.

In this implementation, the terminal device 14 can precisely control the device to be evaluated 11 and the scene simulation device 13, so that all the videos shot by the device to be evaluated 11 are valid. The video is processed twice, which can effectively improve the evaluation efficiency.

In some embodiments, the shooting time of the device to be evaluated 11 in each shooting scene is greater than or equal to a specified duration. For example: the shooting time of the device to be evaluated 11 in each shooting scene is greater than or equal to 10s. In this way, the problem of invalid video clips caused by too short shooting time can be effectively avoided. For example, if the shooting time is short, the normal frame rate adjustment of the device 11 to be evaluated cannot be completed.

Therefore, the scene simulation device 13 can be automatically controlled by the terminal device 14 to accurately simulate various shooting scenes specified in the frame rate adjustment rules of the device to be evaluated 11, so as to ensure that the shooting scene and frame rate adjustment used when evaluating the device to be evaluated 11 The shooting scenes specified in the rules are unified to improve the evaluation accuracy of the frame rate dynamic adjustment performance of the device 11 to be evaluated. Moreover, when the device to be evaluated 11 shoots the target 12, the terminal device 14 can be used to control the scene simulation device 13 to switch shooting scenes, so as to obtain videos shot by the device to be evaluated 11 in all preset shooting scenes, so as to evaluate the target object 12 according to the video. Evaluate the frame rate dynamic adjustment performance of the device 11 in all shooting scenarios specified in the frame rate adjustment rules.

In step S603, the frame rate dynamic adjustment performance of the device to be evaluated 11 is evaluated according to the video.

FIG. 9 is a flow chart of a method 900 for evaluating the frame rate dynamic adjustment performance of a device to be evaluated provided by an embodiment of the present application.

As shown in Figure 9, the method 900 includes the following steps S901-step S903:

Step S901, generating a frame rate change map according to the video.

The frame rate change graph includes the relationship between the frame rate and time used by the device to be evaluated 11 when shooting the target 12, and the frame rate change graph reflects the actual frame rate used by the device to be evaluated 11 when it is tested in the evaluation system 100, and also It is the real ability of the device under evaluation 11 to dynamically adjust the frame rate during actual use. You can refer to the frame rate change diagram shown in FIG. 10 . As shown in FIG. 10 , the device to be evaluated 11 uses 60 FPS within 0s-10s, and uses 30 FPS within 10s-20s.

Step S902: Obtain the first frame rate corresponding to each time point between the switching time point and the previous switching time point, and the switching time point and the next switching time point according to the switching time point and frame rate change diagram of the parameters of the scene simulation device The second frame rate corresponding to each time point between.

When the terminal device 14 controls the scene simulation device 13 to switch parameters, record the switch time point at which the scene simulation device 13 switches parameters. Taking Figure 10 as an example for illustration, if the switching time point recorded by the terminal device 14 is 10s, the first frame rate of the device to be evaluated 11 at each time point between the switching time point and the previous switching time point is 60FPS, and the to-be-evaluated The second frame rate of the device 11 at each time point between the switching time point and the next switching time point is 30 FPS.

Step S903, evaluating the frame rate dynamic adjustment performance of the device to be evaluated 11 according to each first frame rate and each second frame rate.

If each first frame rate and each second frame rate are different, and each second frame rate includes at least one different frame rate, the frame rate dynamic adjustment performance of the device to be evaluated 11 is poor. In this case, although the device to be evaluated 11 has adjusted the frame rate used according to the switching of the shooting scene, the ability of the device to be evaluated 11 to dynamically adjust the frame rate is not stable, so the adjusted frame rate will be inconsistent , that is, at least one different frame rate occurs in the second frame rate. In some embodiments, the at least one different frame rate usually occurs n after the switching time point (n is a positive integer greater than 0, and n is less than the number of time points between the switching time point and the next switching time point) point in time. You can refer to the frame rate change diagram shown in Figure 11. As shown in Figure 11, if the switching time point recorded by the terminal device 14 is 10s, the first frame rate of the device to be evaluated 11 at each time point within 0s-10s is 60FPS , the second frame rate corresponding to the device to be evaluated 11 at 10s is 15FPS, and the second frame rate corresponding to 11s-20s is 30FPS. It can be seen that different frame rates appear in each second frame rate, that is, the dynamic frame rate adjustment is not smooth, the frame rate adjustment performance of the device to be evaluated 11 is unstable, and the frame rate dynamic adjustment performance of the device to be evaluated 11 is poor.

If each first frame rate and each second frame rate are different, and each second frame rate is the same, the frame rate dynamic adjustment performance of the device to be evaluated 11 is better. In this case, it shows that the device to be evaluated 11 not only adjusts the frame rate used according to the switching of the shooting scene, but also the ability of the device to be evaluated 11 to dynamically adjust the frame rate is stable, so the adjusted frame rate is consistent everywhere, that is The second frame rates are the same. Reference may be made to the frame rate variation diagram shown in FIG. 10 , which will not be described here.

In some embodiments, the terminal device 14 evaluates the frame rate of the device to be evaluated 11 according to each first frame rate and each second frame rate before dynamically adjusting the performance, and also according to each second frame rate and the frame rate of the device to be evaluated 11 An adjustment rule is used to evaluate the frame rate dynamic adjustment performance of the device 11 to be evaluated.

FIG. 12 is a flowchart of a method 1200 for evaluating the frame rate dynamic adjustment performance of a device to be evaluated provided by an embodiment of the present application. As shown in FIG. 12 , method 1200 includes step S1201-step S1206, wherein step S1201-step S1202 and step S1206 respectively correspond to step S901-step S903 in method 900, which will not be repeated here. Step S1203-step S1205 is specifically described as follows:

Step S1203, according to the switching time point of the parameters of the scene simulation device, obtain the switched scene parameter corresponding to the switching time point.

When the terminal device 14 adjusts the parameters of the scene simulation device 13 , it also records the parameters of the switched scene simulation device 13 , that is, there is a corresponding relationship between the switching time point and the parameters of the switched scene simulation device 13 . Thus, the terminal device 14 can determine the parameters of the switched scene simulation apparatus 13 corresponding to each switching time point according to the correspondence between the switching time points and the parameters of the switched scene simulation apparatus 13 . There is a corresponding relationship between the parameters of the scene simulation device 13 after switching and the scene parameters after switching, thus, the parameters of the scene after switching can be determined according to the parameters of the scene simulation device 13 after switching.

Step S1204, according to the switched scene parameters and the frame rate adjustment rule, obtain the third frame rate corresponding to the switched scene parameters.

The frame rate adjustment rules stipulate the corresponding relationship between the shooting scene and the scene parameters, and the corresponding relationship between the shooting scene and the frame rate. Therefore, the switched shooting scene can be determined according to the switched scene parameters, and the switched scene can be further determined. The corresponding frame rate is the third frame rate.

Step S1205, evaluating the frame rate dynamic adjustment performance of the device to be evaluated 11 according to the third frame rate and each second frame rate.

Whether the device to be evaluated 11 can be adjusted to a correct frame rate can be evaluated according to the third frame rate and each second frame rate. Wherein, if the third frame rate is the same as the second frame rates, the frame rate dynamic adjustment performance of the device to be evaluated 11 is better. With reference to the frame rate change diagram shown in FIG. 10 , description is made by taking the parameter of the scene simulation device 13 as the brightness in the illumination parameter as an example. If the brightness of 0s-10s is 150Lux, the switching time point is 10s, and the brightness of 10s-20s is 80Lux. The frame rate adjustment rule of the device to be evaluated 11 stipulates that when the brightness is greater than 100 Lux, the designated frame rate is 60 FPS. The brightness is less than or equal to 100Lux, and the specified frame rate is 30FPS. It can be seen from Figure 10 that the second frame rate of the device to be evaluated 11 at each time point within 10s-20s is 30FPS, which conforms to the frame rate adjustment rule, that is, the device to be evaluated 11 adjusts to the correct frame rate, and the frame rate of the device to be evaluated 11 The dynamic adjustment performance is better.

If the third frame rate is different from the second frame rates, the frame rate dynamic adjustment performance of the device to be evaluated 11 is poor. For example, referring to the frame rate change graph shown in FIG. 13 , the parameter of the scene simulation device 13 is the brightness in the illumination parameter as an example for description. If the brightness of 0s-10s is 150Lux, the switching time point is 10s, and the brightness of 10s-20s is 80Lux. As shown in FIG. 13 , the first frame rate of the device to be evaluated 11 at each time point within 0s-10s is 60FPS, and the second frame rate of the device to be evaluated 11 at each time point within 10s-20s is also 60FPS. Comply with frame rate adjustment rules. The device to be evaluated 11 does not dynamically adjust the frame rate according to the change of the shooting scene, and the dynamic adjustment performance of the frame rate of the device to be evaluated 11 is poor.

For another example, the description may be made by referring to the frame rate change diagram shown in FIG. 14 and taking the parameter of the scene simulation device 13 as the brightness in the lighting parameter as an example. If the brightness of 0s-10s is 150Lux, the switching time point is 10s, and the brightness of 10s-20s is 80Lux. As shown in Figure 14, the first frame rate of the device to be evaluated 11 at each time point within 0s-10s is 60FPS, and the second frame rate of the device to be evaluated 11 at each time point within 10s-20s is 15FPS, which does not comply with Frame rate adjustment rules. The device to be evaluated 11 adjusts the frame rate incorrectly according to the change of the shooting scene, resulting in frame loss, and the dynamic adjustment performance of the frame rate of the device to be evaluated 11 is poor.

The terminal device 14 can synthesize the first evaluation result obtained according to the first frame rate and the second frame rate, and the second evaluation result obtained according to the second frame rate and the frame rate adjustment rule, and evaluate the dynamic adjustment of the frame rate of the device 11 to be evaluated. performance. For example: if the second evaluation result is that the frame rate dynamic adjustment performance is poor, directly evaluate the frame rate dynamic adjustment performance of the device to be evaluated 11 is poor. Alternatively, if the second evaluation result shows that the frame rate dynamic adjustment performance is poor, but the first evaluation result shows that the frame rate dynamic adjustment performance is good, it is estimated that the frame rate dynamic adjustment performance of the device 11 to be evaluated is average. Alternatively, if the second evaluation result shows that the frame rate dynamic adjustment performance is better, and the first evaluation result shows that the frame rate dynamic adjustment performance is better, then it is estimated that the frame rate dynamic adjustment performance of the device to be evaluated 11 is better. In some embodiments, the comprehensive evaluation rules may be set according to the required accuracy of the device 11 to be evaluated, which is not specifically limited here.

Thus, the terminal device 14 can automatically analyze the frame rate dynamic adjustment performance of the device to be evaluated 11 according to the video captured by the device to be evaluated 11, so as to effectively improve the evaluation efficiency.
