Description

Evaluation system, method and device for dynamic frame rate adjustment performance

Technical Field

The embodiment of the application relates to the field of electronic equipment, in particular to an evaluation system, an evaluation method and an evaluation device for dynamic frame rate adjustment performance.

Background

The electronic device captures video at a certain Frame Rate (Frame Rate), i.e., the electronic device captures images of a specified number of frames in one second. The video captured by the electronic device will also be played at the frame rate used in the capture. For the same frame rate, other parameters when the electronic device shoots the video can also affect the playing effect of the video. For example: the electronic equipment shoots videos according to the same frame rate, if the background brightness of an object to be shot is lower during shooting, the playing effect of the shot video is more stuck, and if the background brightness of the object to be shot is higher during shooting, the playing effect of the shot video is smoother.

In order to improve the playing effect of the video, the electronic equipment shoots the video by using a dynamic frame rate, namely, the electronic equipment dynamically adjusts the used frame rate according to a preset frame rate adjusting rule and the change of environmental parameters. For example: if the background brightness of the object to be photographed is low at the time of photographing, the electronic device performs photographing using a high frame rate. If the background brightness of the object to be photographed is high at the time of photographing, the electronic device performs photographing using a low frame rate.

When the frame rate is dynamically adjusted, the electronic equipment may be limited by self-operation capability, device reasons and the like, so that the problems of frame loss, unsmooth frame rate switching and the like are caused, and further the problems of video frame loss, frame skipping and the like are caused. It can be seen that the frame rate dynamic adjustment performance of an electronic device directly affects the video capture performance of the electronic device. Thus, the video shooting performance of the electronic device can be evaluated according to the frame rate dynamic adjustment performance of the electronic device. However, the existing system for evaluating the dynamic frame rate adjustment performance of the electronic device cannot accurately simulate various shooting scenes of the electronic device, so that the dynamic frame rate adjustment effect of the electronic device under various shooting scenes cannot be accurately determined, and further the dynamic frame rate adjustment performance of the electronic device cannot be accurately evaluated.

Detailed Description

The terms first, second, third and the like in the description and in the claims and drawings are used for distinguishing between different objects and not for limiting the specified sequence.

In the embodiments of the present application, words such as "exemplary" or "such as" are used to mean serving as an example, instance, or illustration. Any embodiment or design described herein as "exemplary" or "for example" should not be construed as preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "such as" is intended to present related concepts in a concrete fashion.

The terminology used in the description of the embodiments of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application, as will be described in detail with reference to the accompanying drawings.

In the process that the electronic equipment shoots the video by using the dynamic frame rate, the electronic equipment dynamically adjusts the used frame rate according to the preset frame rate adjustment rule and the change of the environmental parameters. Taking a mobile phone as an example for illustration, if the frame rate adjustment rule of the mobile phone is that 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 handset is 30FPS. Thus, assuming that the mobile phone monitors the ambient brightness as 110Lux during the video shooting process, the mobile phone uses 60FPS for shooting. If the mobile phone monitors that the ambient brightness is changed to 80Lux, the mobile phone is switched to 30FPS for shooting. However, when the electronic device dynamically adjusts the frame rate, the electronic device may be limited by its own computing power and device reasons, so that the frame loss and the frame rate switching are not smooth, and further the frame loss and the frame skip of the video are caused. It can be seen that the frame rate dynamic adjustment performance of an electronic device directly affects the video capture performance of the electronic device. Thus, the video shooting performance of the electronic device can be evaluated according to the frame rate dynamic adjustment performance of the electronic device. However, the existing system for evaluating the dynamic frame rate adjustment performance of the electronic device cannot accurately simulate various shooting scenes of the electronic device, so that the dynamic frame rate adjustment effect of the electronic device under various shooting scenes cannot be accurately determined, and further the dynamic frame rate adjustment performance of the electronic device cannot be accurately evaluated.

In order to solve the above problems, the embodiments of the present application provide an evaluation system for dynamic frame rate adjustment performance, so as to accurately simulate various required shooting scenes by using the evaluation system, thereby implementing accurate evaluation of dynamic frame rate adjustment performance of an electronic device. Fig. 1 is a schematic diagram of an evaluation system 100 for dynamic adjustment performance of a frame rate according to an embodiment of the present application. The evaluation system 100 is used for evaluating the frame rate dynamic adjustment performance of the device under evaluation 11. As shown in fig. 1, the evaluation system 100 includes: an object 12, a scene simulation apparatus 13, and a terminal device 14.

The device to be evaluated 11 has a video capturing function, and the device to be evaluated 11 may be a mobile phone, a video camera, a digital camera, etc. The device under evaluation 11 adjusts the frame rate used in different shooting scenes in accordance with the frame rate adjustment rule. The frame rate adjustment rule includes a specified frequency used by the device under evaluation 11 under various photographing scenes, and may be stored in a table, a list, or the like, in which a correspondence between photographing scenes and specified frame rates is recorded. Each of the photographed scenes may be characterized by a scene parameter, with different photographed scenes corresponding to different scene parameters. Thus, the correspondence between the scene parameters and the specified frame rate can be obtained according to the frame rate adjustment rule.

Scene parameters of a photographed scene may include: the movement parameters of the device to be evaluated 11, the illumination parameters, the movement parameters of the photographed object. The motion parameters of the device under evaluation 11 are used to characterize the motion state of the device under evaluation 11 during the shooting process, for example, the device under evaluation 11 is in a stationary state or in a motion state during the shooting process. The motion parameters of the device under evaluation 11 include: parameters such as motion amplitude, motion frequency and motion direction are used to describe the motion trajectory of the device 11 to be evaluated. The illumination parameters are used to characterize the light effect of the environment in which the device under evaluation 11 is located during the shooting process, and may include: luminance and color temperature, and lighting parameters may also include parameters such as color. The motion parameters of the photographed object are used to characterize the motion state of the photographed object during photographing, such as the photographed object being in a stationary state or in a motion state during photographing. The motion parameters of the photographed article include: the movement speed, the movement direction and the like, and the parameters are used for describing the movement track of the photographed object. In some embodiments, the scene parameters may also include other parameters used to characterize the photographed scene, such as: shooting a background, etc.

In some embodiments, scene parameters corresponding to different shooting scenes may be obtained by analyzing the actual shooting scene of the device under evaluation 11. In one implementation, scene parameters corresponding to the shooting scene of the device under evaluation 11 may be analyzed by a convolutional neural network model. In another implementation, the scene parameters corresponding to the shooting scene of the device under evaluation 11 may be analyzed by means of analog analysis.

The evaluation system 100 is used for evaluating the frame rate dynamic adjustment performance of the device under evaluation 11, and since the frame rate dynamic adjustment performance of the device under evaluation 11 is related to the shooting scene in which the device under evaluation 11 is shooting video, the evaluation system 100 needs to have a function of simulating the shooting scene of the device under evaluation 11.

The evaluation system 100 simulates the object photographed by the device under evaluation 11 through the object 12. In this embodiment, the target object 12 may be an image of an actual object, for example: images of people, scenery, objects, etc. The object 12 may also be an image with a certain rule, for example: the object 12 is an image including a plurality of squares of the same size, which are arranged laterally in accordance with a rule that the gradation value gradually increases. The number of objects 12 in the same evaluation system 100 may be N (N is a positive integer greater than 0), and if the number of objects 12 is plural, the image contents of the objects 12 may be all the same, partially the same, or all different.

The evaluation system 100 simulates a shooting scene of the device under evaluation 11 to be evaluated when shooting the target object 12 by the scene simulation means 13. The scene simulation means 13 comprise a plurality of adjustable parameters, by setting which a shooting scene of the object 13 can be constructed when the device 11 to be evaluated shoots.

In some embodiments, in order to improve the simulation precision of the scene simulation device 13, the scene simulation device 13 may accurately restore the real shooting scene of the target object 12 shot by the device 11 to be evaluated. The scene simulation means 13 comprise a plurality of adjustable parameters of the same type as the scene parameters of the real shooting scene of the object 12 shot by the device under evaluation 11. For example: if the scene parameters comprise illumination parameters, the parameters of the scene simulation means 13 also comprise illumination parameters. Another example is: if the scene parameters include illumination parameters and motion parameters of the photographed item, the parameters of the scene simulation means 13 also include illumination parameters and motion parameters of the object 12.

The various adjustable parameters of the scene simulation device 13 are realized by corresponding devices. For example: the vibration device is used for installing the equipment 11 to be evaluated, and has a vibration function and is used for driving the equipment 11 to be evaluated to vibrate. The parameters of the vibration device are vibration parameters, including: vibration frequency, vibration amplitude and vibration direction. Wherein the vibration frequency corresponds to the movement frequency of the device to be evaluated 11 in the scene parameter, the vibration amplitude corresponds to the movement amplitude of the device to be evaluated 11 in the scene parameter, and the vibration direction corresponds to the movement direction of the device to be evaluated 11 in the scene parameter. In some embodiments, the device under evaluation 11 may be brought to a stationary state by setting the vibration means to a stationary state. The illumination means is for providing background illumination to the object 12. The parameters of the illumination device are illumination parameters, including: brightness and color temperature. The brightness of the illumination device corresponds to the brightness in the illumination parameters of the scene parameters, and the color temperature of the illumination device corresponds to the color temperature in the illumination parameters of the scene parameters. In some embodiments, the varying accuracy of the illumination device may be set to 1Lux to cover a High-Dynamic Range (HDR) scene. The moving device is used for installing the object 12, and has a moving function and is used for driving the object 12 to move. The parameters of the motion device are motion parameters, including: speed of movement and direction of movement. The motion speed corresponds to the motion speed of the shot object in the scene parameter, and the motion direction corresponds to the motion direction of the shot object in the scene parameter. In some embodiments, the object 12 may be placed in a stationary state by setting the motion device to a stationary state. The background device is used for providing a background for the object 12, and parameters of the background device are background parameters, including: background pattern. The background pattern corresponds to a shooting background in the scene parameters.

At least one of the above devices may be provided in the scene simulation device 13 to meet the evaluation requirements of different devices 11 to be evaluated.

In one implementation, the evaluation system 100 only evaluates parameters corresponding to devices included in the scene simulation device 13 for a certain model of the device under evaluation 11, and the parameters are only the same as the scene parameters of each shooting scene in the frame rate adjustment rule of the device under evaluation 11 of the model. Taking the evaluation system 100 as an example for evaluating only the device under evaluation 11 of model a, if the scene parameters of each shooting scene in the frame rate adjustment rule of the device under evaluation 11 of model a include: the illumination parameters, and the parameters corresponding to the devices included in the scene simulation device 13 include illumination parameters. As shown in fig. 2, the scene simulation device 13 includes an illumination device 131. Taking the evaluation system 100 as an example for evaluating only the device under evaluation 11 of model B, if the scene parameters of each shooting scene in the frame rate adjustment rule of the device under evaluation 11 of model B include: the parameters of the photographed object and the motion parameters of the device under evaluation 11, the parameters corresponding to the means comprised by the scene simulation means 13 include the motion parameters of the object 12 and the motion parameters of the device under evaluation 11. As shown in fig. 3, the scene simulation device 13 includes a moving device 132 and a vibrating device 133. In this implementation manner, the scene simulation device 13 has stronger simulation pertinence, and relatively, the number of devices included in the scene simulation device 13 is relatively small, the overall cost of the scene simulation device 13 is low, and the maintenance is easier. If a different device to be evaluated 11 needs to be evaluated, the existing scene simulation apparatus 13 in the evaluation system 100 may be replaced with a corresponding scene simulation apparatus 13.

In another implementation manner, the evaluation system 100 evaluates parameters corresponding to devices included in the scene simulation device 13 for the devices 11 to be evaluated with different models, including scene parameters of each shooting scene in frame rate adjustment rules of the devices 11 to be evaluated with different models. The evaluation system 100 is described by taking as an example the device under evaluation 11 for evaluating model a and model B. The scene parameters of each shooting scene in the frame rate adjustment rule of the to-be-evaluated device 11 of model a include: the scene parameters of each shooting scene in the frame rate adjustment rule of the illumination parameter, model B, of the device under evaluation 11 include: the parameters of the motion of the device under evaluation 11 and the motion of the photographed object, the parameters of the scene simulation means 13 corresponding to the means comprising the illumination parameters, the motion of the photographed object and the motion of the device under evaluation 11. As shown in fig. 4, the scene simulation device 13 includes an illumination device 131, a movement device 132, and a vibration device 133. In this implementation manner, the scene simulation device 13 has a wider simulation range, and the same evaluation system 100 can meet the evaluation requirements of different devices 11 to be evaluated, so that the scene simulation device 13 does not need to be replaced to meet the evaluation requirements of different devices 11 to be evaluated, and the evaluation operation is more convenient. Moreover, by using the same evaluation system 100 to evaluate different devices 11 to be evaluated, it is possible to improve the consistency of conditions other than the shooting scene simulated by the scene simulation means 13 when evaluating each device 11 to be evaluated, to improve the consistency of evaluating each device 11 to be evaluated, and to make the evaluation result more reliable.

In the above-mentioned scene simulation device 13, the moving device 132 is located between the illumination device 131 and the vibration device 133, so that the illumination device 131 provides background illumination for the object 12 on the moving device 132.

The evaluation system 100 is used for evaluating the frame rate dynamic adjustment performance of the device under evaluation 11, i.e. for testing the performance of the device under evaluation 11 in dynamically adjusting the frame rate under different shooting scenarios. Thus, the evaluation system 100 needs to dynamically switch the shooting scene of the device under evaluation 11 during the video shooting of the device under evaluation 11 to trigger the device under evaluation 11 to adjust the frame rate used in accordance with the frame rate adjustment rule.

The scene simulation device 13 is connected with the terminal equipment 14, and the terminal equipment 14 is used for controlling the parameters of the scene simulation device 13 to be switched in the process of shooting 12 the target object by the equipment 11 to be evaluated so as to control the shooting scene when the equipment 11 to be evaluated is switched to shoot 12 the target object.

Above the above components, an operating system such as iOS operating system, android operating system, windows operating system, and the like is run.

In order to accurately evaluate the frame rate dynamic adjustment performance of the device under evaluation 11, the embodiment of the present application provides an evaluation method of the frame rate dynamic adjustment performance, according to which the terminal device 14 can evaluate the frame rate dynamic adjustment performance of the device under evaluation 11. Fig. 6 is a flow chart of a method 600 provided by an embodiment of the present application. As shown in fig. 6, the method 600 includes the following steps S601-S603:

in step S601, in the process of capturing the object by the device under evaluation 11, parameters of the scene simulation apparatus are adjusted to switch the capturing scene when the device under evaluation 11 captures the object.

Before the device under evaluation 11 photographs the object 12, a photographing preparation work is first performed, the photographing preparation work including: the photographing distance, photographing angle, and the like between the device under evaluation 11 and the object 12 are adjusted so that the device under evaluation 11 is focused on the object 12, and the object 12 is positioned entirely within the viewfinder of the device under evaluation 11. Wherein the fact that the object 12 is located completely within the view-finder frame of the device under evaluation 11 means that: in the case of a movement of the object 12 and/or of the device under evaluation 11, the object 12 can be located completely within the view-finder of the device under evaluation 11.

In one implementation, the device under evaluation 11 is manually controlled to start photographing the target object 12 and to end photographing the target object 12. In another embodiment, the device under evaluation 11 can be controlled by the terminal 14 to start shooting the target object 12 and to end shooting the target object 12. The terminal device 14 controls the device under evaluation 11 to capture the object 12, which may be implemented by a trigger. The trigger is used for triggering the shooting key 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 shooting the target 12 and ends shooting the target 12. Referring to the evaluation system shown in fig. 7, a trigger 15 may be provided on the device under evaluation 11 so that the trigger 15 may trigger a photographing button of the device under evaluation 11. The trigger 15 is connected with the terminal device 14 to control the triggering operation of the trigger 15 by the terminal device 14.

In the process of shooting the target object 12 by the equipment to be evaluated 11, the terminal equipment 14 controls and starts the scene simulation device 13, and controls and adjusts parameters of the scene simulation device 13, so that automatic and continuous switching of various shooting scenes is realized.

In one embodiment, the terminal 14 controls the scene simulator 13 to be activated after the device under evaluation 11 starts shooting the target object 12. In this implementation manner, the video obtained by capturing the target object 12 by the device under evaluation 11 includes a first video clip and a second video clip. The first video clip is a video clip that is photographed in a default photographing environment before the device to be evaluated 11 builds a photographing scene by the scene simulation device 13, that is, before the terminal device 14 controls the scene simulation device 13 to start adjusting parameters. After the device under evaluation 11 starts shooting the target object 12, shooting is performed using the corresponding frame rate according to the default shooting environment, and a first video clip is obtained. The second video clip is a video clip of the device under evaluation 11 photographed in various photographing scenes constructed by the scene simulation means 13. The device under evaluation 11 monitors the change of the shooting scene, determines the frame rate used according to the frame rate adjustment rule, and shoots using the determined frame rate, resulting in a second video clip.

In another implementation, the terminal device 14 controls the device under evaluation 11 to shoot the target object 12, and the terminal device 14 controls the device under evaluation 11 to start shooting the target object 12 while controlling the scene simulator 13 to start working. In this implementation manner, the video obtained by capturing the target object 12 by the device under evaluation 11 includes a third video clip, where the third video clip is a video clip captured by the device under evaluation 11 under various capturing scenes constructed by the scene simulator 13. The video does not include a video clip photographed by the device under evaluation 11 in the default photographing environment. For example: taking the evaluation system shown in fig. 7 as an example, the terminal device 14 controls the scene simulation apparatus 13 and the trigger 15 to be started simultaneously, so as to control the scene simulation apparatus 13 to start working simultaneously with the device 11 to be evaluated.

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

Fig. 8 is a flowchart of a method 800 for adjusting parameters of the scene modeling apparatus 13 by the terminal device 14 according to the embodiment of the present application. As shown in fig. 8, the method 800 includes the following steps S801 to S802:

Step S801 acquires a frame rate adjustment rule of the device under evaluation 11.

The terminal device 14 may acquire the frame rate adjustment rule used by the device under evaluation 11 according to the model of the device under evaluation 11. For example: the terminal device 11 may obtain the frame rate adjustment rule of the device to be evaluated 11 from the internet, the cloud, or the like 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 11 to be evaluated according to the frame rate adjustment rule stored in advance. For example: the frame rate adjustment rules of the various devices under evaluation 11 are stored in the terminal device 14 in advance, and the terminal device 14 can determine the frame rate adjustment rule corresponding to the devices under evaluation 11 from the frame rate adjustment rules stored in advance according to the information of the model and the like of the devices under evaluation 11 input by the user.

Step S802, parameters of a scene simulation device are adjusted according to scene parameters corresponding to each shooting scene.

As is clear from the above description of the frame rate adjustment rule, the frame rate adjustment rule of the device under evaluation 11 includes the specified frame rate corresponding to the device under evaluation 11 under various shooting scenes, and the scene parameter corresponding to each shooting scene. In order to ensure the evaluation integrity of the frame rate dynamic adjustment performance of the device under evaluation 11, i.e. to ensure the ability to evaluate the frame rate dynamic adjustment of the device under evaluation 11 in all shooting scenarios, the terminal device 14 needs to control the scenario simulation means 13 to simulate all preset shooting scenarios, i.e. to simulate all shooting scenarios comprised by the frame rate adjustment rules of the device under evaluation 11. For example: if the frame rate adjustment rule of the device under evaluation 11 includes the shooting scene a and the shooting scene B, the terminal device 14 needs to control the scene simulating means 13 to simulate the shooting scene a and the shooting scene B.

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

In one implementation, the terminal device 14 resets all parameters of the scene simulation means 13 according to the scene parameters of the photographed scene.

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

In some embodiments, the terminal device 14 is connected to each of the scene simulation apparatuses 13 separately to control and adjust the apparatus parameter of each of the scene simulation apparatuses 13, so as to achieve the effect of controlling and adjusting the parameter of the scene simulation apparatus 13. Referring to the evaluation system 100 shown in fig. 2-4, if the scene simulation device 13 includes at least one of the illumination device 131, the movement device 132, and the vibration device 133, the terminal apparatus 14 is connected to the illumination device 131, the movement device 132, and the vibration device 133, respectively.

The terminal device 14 adjusts the device parameters of each of the illumination device 131, the movement device 132, and the vibration device 133 according to the correspondence relationship between the device parameters of the illumination device 131, the movement device 132, and the vibration device 133 described above and the scene parameters of the photographed scene. The terminal 14 adjusts the vibration parameters of the vibration device 133 according to the motion parameters of the device under evaluation 11 corresponding to each shooting scene, for example: the terminal 14 adjusts the vibration frequency of the vibration means 133 in accordance with the movement frequency of the device 11 to be evaluated in the scene parameters. The terminal 14 adjusts the vibration amplitude of the vibration means 133 in accordance with the motion amplitude of the device 11 to be evaluated in the scene parameters. The terminal device 14 adjusts the brightness of the illumination means 131 according to the brightness in the illumination parameters of the scene parameters. The terminal device 14 adjusts the color temperature of the illumination means 131 in accordance with the color temperature in the illumination parameters of the scene parameters. The terminal 14 adjusts the movement speed of the movement means 132 in accordance with the movement speed of the photographed object in the scene parameters. The terminal 14 adjusts the direction of movement of the movement means 132 in accordance with the direction of movement of the photographed item in the scene parameters.

In step S602, a video of the object photographed by the device under evaluation 11 is acquired.

In one implementation, if the terminal device 14 controls the scene simulation apparatus 13 to start operating after the device under evaluation 11 starts shooting the target object 12, the video shot by the device under evaluation 11 includes a first video clip and a second video clip. As can be seen from the description of the first video clip and the second video clip in step S601, the first video clip is not a video clip captured in a preset capturing scene and should not participate in the evaluation, so that the first video clip needs to be deleted from the video, and only the second video clip is subsequently evaluated.

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

In this implementation manner, if the device to be evaluated 11 has weak shooting reaction capability or other auxiliary devices (such as the trigger 15) cause delayed shooting of the device to be evaluated 11, the delayed shooting can be compensated by shooting the first video clip of the device to be evaluated 11 before the scene simulation device 13 starts to work, so as to ensure that the starting point of the second video clip shot by the device to be evaluated 11 can accurately correspond to the second time point when the scene simulation device 13 starts to work, and further ensure the accuracy of subsequent evaluation.

In another implementation, if the terminal device 14 controls the device under evaluation 11 to shoot the target object 12, the terminal device 14 controls the device under evaluation 11 to start shooting the target object 12 while controlling the scene simulator 13 to start working, and the video shot by the device under evaluation 11 includes only the third video clip. As can be seen from the description of the third video segment in step S601, all the third video segments are valid video segments, which can be directly used for subsequent evaluation.

In this implementation manner, the terminal device 14 can accurately control the device to be evaluated 11 and the scene simulation device 13 to make all the videos shot by the device to be evaluated 11 effective, so that the terminal device 14 does not need to perform secondary processing on the videos shot by the device to be evaluated 11, thereby effectively improving the evaluation efficiency.

In some embodiments, the photographing time of the device under evaluation 11 in each photographing scene is greater than or equal to a specified duration. For example: the photographing time of the device under evaluation 11 in each photographing scene is greater than or equal to 10s. In this way, the problem that the video clip is invalid due to too short shooting time can be effectively avoided, for example, the shooting time is short, so that the device 11 to be evaluated cannot complete normal frame rate adjustment.

Thus, the terminal device 14 can automatically control the scene simulation device 13 to accurately simulate various shooting scenes specified in the frame rate adjustment rule of the device 11 to be evaluated, so as to ensure that the shooting scenes used in the process of evaluating the device 11 to be evaluated are unified with the shooting scenes specified in the frame rate adjustment rule, and improve the evaluation accuracy of the frame rate dynamic adjustment performance of the device 11 to be evaluated. Moreover, when the device under evaluation 11 photographs the object 12, the scene simulation means 13 may be controlled by the terminal device 14 to switch the photographing scene to obtain a video of the device under evaluation 11 photographed in all the preset photographing scenes, so as to evaluate the frame rate dynamic adjustment performance of the device under evaluation 11 in all the photographing scenes specified in the frame rate adjustment rule according to the video.

Step S603, dynamically adjusting the performance according to the frame rate of the device under evaluation 11 according to the video evaluation.

Fig. 9 is a flowchart of a method 900 for evaluating frame rate dynamic adjustment performance of a device under evaluation according to an embodiment of the present application.

As shown in fig. 9, the method 900 includes the following steps S901 to S903:

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

The frame rate change map includes a relationship between a frame rate used by the device under evaluation 11 when photographing the object 12 and time, and reflects a frame rate actually used by the device under evaluation 11 when tested in the evaluation system 100, that is, a real ability of the device under evaluation 11 to dynamically adjust the frame rate when actually used. Referring to the frame rate variation chart shown in fig. 10, as shown in fig. 10, the device under evaluation 11 uses 60FPS in 0s-10s and 30FPS in 10s-20 s.

Step S902, according to the switching time point and the frame rate change map of the parameter of the scene simulation device, a first frame rate corresponding to each time point between the switching time point and the last switching time point and a second frame rate corresponding to each time point between the switching time point and the next switching time point are obtained.

When the terminal device 14 controls the switching parameters of the scene modeling device 13, the switching time points of the switching parameters of the scene modeling device 13 are recorded. Taking fig. 10 as an example for explanation, if the switching time point recorded by the terminal device 14 is 10s, the first frame rate of each time point between the switching time point and the last switching time point of the device under evaluation 11 is 60FPS, and the second frame rate of each time point between the switching time point and the next switching time point of the device under evaluation 11 is 30FPS.

Step S903, the frame rate dynamic adjustment performance of the device under evaluation 11 is evaluated based on each first frame rate and each second frame rate.

If the first frame rates and the second frame rates are different and the second frame rates include at least one different frame rate, the frame rate dynamic adjustment performance of the device under evaluation 11 is poor. In this case, although the device under evaluation 11 adjusts the frame rate used in accordance with the switching of the shooting scene, the ability of the device under evaluation 11 to dynamically adjust the frame rate is not stable, and thus, an inconsistency in the adjusted frame rate, that is, at least one different frame rate in the second frame rate, may occur. In some embodiments, the at least one different frame rate generally occurs at n (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) time points after the switching time point. Referring to the frame rate change chart shown in fig. 11, as shown in fig. 11, if the switching time point recorded by the terminal device 14 is 10s, the first frame rate of the device under evaluation 11 at each time point within 0s-10s is 60FPS, the second frame rate of the device under evaluation 11 at 10s is 15FPS, and the second frame rate at 11s-20s is 30FPS. It can be seen that different frame rates appear in the second frame rates, that is, the dynamic adjustment of the frame rate is not smooth, the performance of adjusting the frame rate by the device under evaluation 11 is unstable, and the dynamic adjustment performance of the frame rate by the device under evaluation 11 is poor.

If the first frame rate and the second frame rate are different and the second frame rates are the same, the frame rate dynamic adjustment performance of the device under evaluation 11 is better. In this case, it is explained that the device under evaluation 11 not only adjusts the frame rate used in accordance with the switching of the shooting scene, but also the ability of the device under evaluation 11 to dynamically adjust the frame rate is stable, and therefore the adjusted frame rates are uniform throughout, that is, the second frame rates are the same. Reference may be made to the frame rate variation diagram shown in fig. 10, which is not described here in detail.

In some embodiments, before the terminal device 14 evaluates the frame rate dynamic adjustment performance of the device under evaluation 11 according to the first frame rate and the second frame rate, the frame rate dynamic adjustment performance of the device under evaluation 11 is also evaluated according to the second frame rate and the frame rate adjustment rule of the device under evaluation 11.

Fig. 12 is a flowchart of a method 1200 for evaluating frame rate dynamic adjustment performance of a device under evaluation according to an embodiment of the present application. As shown in fig. 12, the method 1200 includes steps S1201-S1206, where steps S1201-S1202 and S1206 correspond to steps S901-S903 in the method 900, respectively, and are not described herein. The following specific description is made for step S1203 to step S1205:

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

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

Step S1204, obtaining a third frame rate corresponding to the switched scene parameter according to the switched scene parameter and the frame rate adjustment rule.

The corresponding relation between the shooting scene and the scene parameter and the corresponding relation between the shooting scene and the frame rate are specified in the frame rate regulation rule, so that the shooting scene after switching can be determined according to the scene parameter after switching, and the frame rate corresponding to the scene after switching, namely, the third frame rate, is further determined.

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

Based on the third frame rate and the respective second frame rates, it can be evaluated whether the device under evaluation 11 can be adjusted to the correct frame rate. Wherein if the third frame rate is the same as each of the second frame rates, the frame rate dynamic adjustment performance of the device under evaluation 11 is good. The frame rate change map shown in fig. 10 will be described by taking the parameter of the scene simulation device 13 as the luminance among the illumination parameters as an example. If the luminance of 0s-10s is 150Lux, the switching time point is 10s, and the luminance of 10s-20s is 80Lux. The frame rate adjustment rule of the device under evaluation 11 specifies: when the luminance is greater than 100Lux, the frame rate is specified to be 60FPS. The luminance is less than or equal to 100Lux, and the specified frame rate is 30FPS. As can be seen from fig. 10, the second frame rate of the device under evaluation 11 at each time point within 10s-20s is 30FPS, which accords with the frame rate adjustment rule, that is, the device under evaluation 11 adjusts to the correct frame rate, and the dynamic frame rate adjustment performance of the device under evaluation 11 is better.

If the third frame rate and each second frame rate are different, the frame rate dynamic adjustment performance of the device under evaluation 11 is poor. For example: the frame rate change map shown in fig. 13 will be described by taking the parameters of the scene simulation device 13 as the luminance among the illumination parameters as an example. If the luminance of 0s-10s is 150Lux, the switching time point is 10s, and the luminance of 10s-20s is 80Lux. As shown in fig. 13, the first frame rate of the device under evaluation 11 at each time point within 0s-10s is 60FPS, and the second frame rate of the device under evaluation 11 at each time point within 10s-20s is 60FPS, which does not meet the frame rate adjustment rule. The device under evaluation 11 does not dynamically adjust the frame rate according to the change of the shooting scene, and the frame rate dynamic adjustment performance of the device under evaluation 11 is poor.

Another example is: the frame rate change map shown in fig. 14 will be described by taking the parameter of the scene simulator 13 as the luminance of the illumination parameter as an example. If the luminance of 0s-10s is 150Lux, the switching time point is 10s, and the luminance of 10s-20s is 80Lux. As shown in fig. 14, the first frame rate of the device under evaluation 11 at each time point within 0s-10s is 60FPS, the second frame rate of the device under evaluation 11 at each time point within 10s-20s is 15FPS, and the frame rate adjustment rule is not satisfied. The device 11 to be evaluated adjusts the frame rate error according to the change of the shooting scene, so that the frame loss condition occurs, and the dynamic frame rate adjusting performance of the device 11 to be evaluated is poor.

The terminal device 14 may integrate the first evaluation result obtained from the first frame rate and the second evaluation result obtained from the second frame rate and the frame rate adjustment rule to evaluate the frame rate dynamic adjustment performance of the device 11 to be evaluated. For example: if the second evaluation result is that the frame rate dynamic adjustment performance is poor, the frame rate dynamic adjustment performance of the device to be evaluated 11 is directly evaluated to be poor. Alternatively, if the second evaluation result is that the frame rate dynamic adjustment performance is poor, but the first evaluation result is that the frame rate dynamic adjustment performance is good, it is general to evaluate the frame rate dynamic adjustment performance of the device under evaluation 11. Or if the second evaluation result is that the frame rate dynamic adjustment performance is better, and the first evaluation result is that the frame rate dynamic adjustment performance is better, the frame rate dynamic adjustment performance of the device to be evaluated 11 is better. In some embodiments, the rules for the comprehensive evaluation may be set according to the required accuracy of the device 11 to be evaluated, and are not particularly limited herein.

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