Detailed Description

To make the objects, technical solutions and advantages of the exemplary embodiments of the present application clearer, the technical solutions in the exemplary embodiments of the present application will be clearly and completely described below with reference to the drawings in the exemplary embodiments of the present application, and it is obvious that the described exemplary embodiments are only a part of the embodiments of the present application, but not all the embodiments.

For the convenience of users, various external device interfaces are usually provided on the display device to facilitate connection of different peripheral devices or cables to implement corresponding functions. When a high-definition camera is connected to an interface of the display device, if a hardware system of the display device does not have a hardware interface of a high-pixel camera receiving the source code, data received by the camera cannot be displayed on a display screen of the display device.

Furthermore, due to the hardware structure, the hardware system of the conventional display device only supports one path of hard decoding resources, and usually only supports video decoding with a resolution of 4K at most, so when a user wants to perform video chat while watching a network television, the user needs to use the hard decoding resources (usually GPU in the hardware system) to decode the network video without reducing the definition of the network video screen, and in this case, the user can only process the video chat screen by using a general-purpose processor (e.g. CPU) in the hardware system to perform soft decoding on the video.

The soft decoding is adopted to process the video chat picture, so that the data processing burden of a CPU (central processing unit) can be greatly increased, and when the data processing burden of the CPU is too heavy, the problem of picture blocking or unsmooth flow can occur. Further, due to the data processing capability of the CPU, when the CPU performs soft decoding on the video chat screen, multi-channel video calls cannot be generally implemented, and when a user wants to perform video chat with multiple other users in the same chat scene, access is blocked.

In view of the above aspects, to overcome the above drawbacks, the present application discloses a dual hardware system architecture to implement multiple channels of video chat data (at least one channel of local video).

In some embodiments, the controller of the display device may be located in only one physical chip, so that two chips may be included as in the above embodiments, and the controllers in the a chip and the N chip together serve as a control module.

A first aspect of some embodiments of the present application shows a display device comprising:

a first interface of the display device in a fitness environment is shown in fig. 8-1. Fig. 8-1 is a schematic diagram of a first interface 200A, wherein the first interface 200A can display a plurality of exemplary videos in a scrolling manner, so that a user can select a target exemplary video from the plurality of exemplary videos.

Referring to fig. 8-1, a display window is shown for displaying an exemplary video selected by a user. A confirmation instruction input by the user is received, and when the user selects the control to start training in the first interface 200A, based on the "start training" control position of the selector (focus) in the first interface. In response to user selection of the start training control, the controller may retrieve and load a corresponding exemplary video film source from the server based on an API (Application Programming Interface).

Referring to fig. 8-2, fig. 8-2 is a schematic diagram of a fitness video first interface page, which may be referred to as a detail interface, showing a fitness video first interface page according to some embodiments, wherein the first interface may display a plurality of trainer videos in a scrolling manner for a user to select a target one of the plurality of example videos. For example: squatting deeply, raising legs, backswing, and four-point kicking legs … …. The user selects a target demonstration video among a plurality of coach videos.

In the first interface, a playing window is arranged, the playing window is used for playing a default training video or a training video played last time in a playing history, an introduction display control, a "training start" control (namely a playing control) and at least one of a "collection" control are arranged on the right side of the playing window, the interface further comprises a training list control, and a plurality of training video display controls are displayed in the training list control.

In some embodiments, after the start training control or the play window is selected, the demonstration video may be obtained after verification. Specifically, displaying and storing a pre-downloaded demonstration video; a mapping between the exemplary video and the check code is then established. In response to user selection of the start training control, a verification code is generated based on the user-selected demonstration video. The controller may obtain, from among the stored demonstration videos, a demonstration video corresponding to the check code based on the check code. Because the demonstration video is stored in advance, the controller can directly call the demonstration video corresponding to the check code after acquiring the check code. By calling the demonstration video in the mode, the problem of blocking caused by factors such as a network can be avoided, the demonstration video can be downloaded in advance by the previous acquisition, and the fluency of the demonstration video is improved.

The camera is used for acquiring a local image or a local video; when the mobile phone is not opened, the camera is located at the hidden position so that the edge of the display device can be kept smooth, and after the mobile phone is opened, the camera is lifted to be protruded above the edge of the display device so as to avoid the shielding of the display screen to acquire image data.

In some embodiments, in response to selection of a training start control by a user, the camera is raised and started to acquire image data, the camera is always in an open state during the training process, local videos are collected in real time, and the collected local videos are sent to the controller so as to display the actions of the user on the follow-up training interface. Thus, the user can watch the motion of the user and the motion of the demonstration video in real time.

In some embodiments, in response to user selection of the start training control, the camera is raised, but in a standby state, and each time the demonstration video is played to a preset time point, a local image is captured and sent to the controller. This relieves the processor of stress and maintains the local image displayed on the display screen until the next point in time.

A controller configured to: receiving input confirmation operation on the playing control, starting a camera, and loading video data of the demonstration video;

in one implementation, in response to a confirmation operation, the confirmation operation may be a selection of a start training control. The controller is further configured to control the display to display a prompt interface 200C (and a guide interface) for instructing a user to enter a predetermined area. Specific prompting interfaces can be seen in fig. 9-1 and 9-2. Specifically, fig. 9-1 is a schematic diagram of a prompt interface according to some embodiments, according to which a user adjusts his/her position. When the user finishes entering the preset area, the controller controls the display to display the second interface. The reason is that the acquisition area of the camera is marginal, so that local data can be acquired better, the camera acquires a current image, a floating layer is newly built above a layer displaying the current image in the displaying process, the optimal acquisition area is determined in the floating layer according to the position and the angle of the camera, and an optimal position frame is displayed in the floating layer according to the optimal acquisition area. The user is guided to move the position, the position in the acquired current image is overlapped with the frame of the optimal position in the floating layer, when the overlapping degree reaches a preset threshold value, the display equipment displays a successful prompt message, the floating layer is cancelled, and the follow-up interface shown in the figure 10 is skipped.

For example, in some embodiments, the user is prompted to move to the right by prompting the user to move to the left in the box area 200C1 for the person in the prompt interface 200C. If the person in the display frame is located at the right side of the square frame area, correspondingly prompting the user to move towards the left side so as to enable the user to enter a preset area, wherein the preset area can be acquired by a camera. The embodiment of the application shows that the user is instructed to enter the predetermined area through the mode. In some embodiments, the prompt interface is further configured to display a prompt message, specifically, referring to fig. 9-2, where fig. 9-2 is a schematic diagram of the prompt interface according to some embodiments, and the prompt message is "please face the screen. Keep the body standing alone ", and the like. The message prompting the user to move can be characters displayed on the floating layer, can also be a voice prompt, and can also be an indication mark pointing to the optimal position frame.

In one implementation, the controller may also directly display the second interface in response to the confirmation operation, play the demonstration video in the first playing window, and play the local image in the second video window. The user may adjust the position of the user in accordance with the image displayed in the second video window in the second interface.

In an implementation manner, the controller may also determine, in response to the confirmation operation, the number of occurrences of the position guidance interface, display the guidance interface when the number of display times of the guidance interface does not satisfy a preset value, directly display the second interface when the preset value is satisfied, play the demonstration video in the first play window, and play the local image in the second video window. The user may adjust the position of the user in accordance with the image displayed in the second video window in the second interface.

Specifically, referring to fig. 10, fig. 10 is a schematic diagram of a second display interface 200B according to some embodiments, where the second display interface 200B includes a first play window 200B1 for playing the exemplary video and a second play window 200B2 for playing the local image captured by the camera.

In some embodiments, the demonstration video is played in the first playing window, the joint point is not shown in the demonstration video, and the playing of the local image data by the second playing serial port includes that the controller acquires the position of the joint point of the video-associated local image data according to the local image data, and displays the video-associated local image data and the joint point mark on the second playing window after superimposing the local image data and the joint point mark according to the position of the joint point.

In some embodiments, overlaying the local image data and the joint point mark may add a joint point mark on the local image according to the position of the joint point in the local image data, and then output on a layer to display the local image after overlaying the joint point. The local image acquired by the camera can be displayed in one layer, the floating layer is added above the layer, the joint surface mark is added in the floating layer according to the position of the joint point, and the two layers are displayed after being superposed.

In some embodiments, the second playing window directly plays the local video collected by the camera.

The embodiment of the application shows a display device, which comprises a display, a camera and a controller. The controller is configured to respond to the selection of a user on a starting training control in the display interface, acquire a demonstration video, and raise and start a camera, wherein the camera is used for collecting local graphs; and controlling a first playing window of the display to play the demonstration video, and displaying the local image in a second playing window of the display. Therefore, according to the technical scheme shown in the embodiment of the application, the demonstration video is displayed through the first playing window, the local picture is displayed through the second playing window, and the user can timely adjust the action of the user through comparison of the displayed contents in the two windows in the exercise process, so that the experience of the user is improved.

The camera is used for collecting local videos, and the local videos are continuous local image sets. In the comparison process, if the comparison is performed for each frame of image, the data processing amount of the controller is large.

In some feasible embodiments based on the above problem, the controller may compare the local image with the demonstration video frame to generate a comparison result, and the user may view the comparison result through the display interface after the user exercises, so as to help the user better understand the action defect of the user, so that the user can overcome the action defect in the subsequent exercise process. Wherein the demonstration video frame is a graph corresponding to the local image in a demonstration video.

In some embodiments, there are multiple implementations of capturing the local image.

For example, the controller may control the camera to capture a local image when the demonstration video is played to a preset time point; and then comparing the local image acquired by the camera with the pre-stored demonstration video frame to obtain a comparison result. In some embodiments may be: when the demonstration video is played to a preset time point, the controller can control the camera to collect a local image. The preset time point may be a preset time point until the last frame of image of the demonstration video appears, each time interval T being from the beginning of the appearance of the first image of the demonstration video. The preset time point may also be generated based on the content of the demonstration video, where each action node in the content of the demonstration video is used as a preset time point. For example, for an exemplary video with a starting point of 3S for the first image to appear, a T time of 10S, and a length of 53S. The corresponding preset time points are as follows: 3S, 13S, 23S, 33S, 43S and 53S, the controller controls the camera to capture a local image when the video is released to play to 3S, 13S, 23S, 33S, 43S and 53S, respectively. Labels are added to the demonstration video according to preset time nodes, and when the labels are played, local images are collected.

For another example, the camera is always in an open state, and records a local video in real time, and the local video is sent to the controller. The controller can extract corresponding local images in the collected local videos at a preset time point; and then comparing the extracted local image with a pre-stored demonstration video frame to obtain a comparison result. The specific implementation process comprises the following steps: when the demonstration video is played to a preset time point, the controller extracts one or more local images from the local video collected by the camera. The preset time point may be a preset time point until the last frame of image of the demonstration video appears, each time interval T (i.e. the time when the demonstration action appears) starting from the appearance of the first image of the demonstration video. The preset time point may also be generated or pre-marked based on the content of the demonstration video, where each action node in the content of the demonstration video serves as a preset time point. For example, for an exemplary video, the starting point of the first image is 3S, and the predetermined time points are: 3S, 16S, 23S, 45S and 53S, the controller will capture a local image in the local video when the video play is released to 3S, 16S, 23S, 45S and 53S. It will be appreciated that the time of occurrence of the exemplary action is arbitrary and the acquisition of the images to be compared is triggered based on the label or point in time identifying the exemplary action.

Usually, the user imitates the action of the coach after watching the action of the coach playing the demonstration video. There is naturally a certain delay from the time the user receives the demonstration action to the time the corresponding action is taken. In order to counteract the delay, the technical scheme shown in the embodiment of the application shows a "delayed image acquisition method". In this embodiment, a concept of a delayed acquisition time point is introduced, wherein the delayed acquisition time point is a preset time point + a preset reaction time length. When the demonstration video is played to the time point of delaying acquisition, the controller controls the camera to acquire the local video.

The technical scheme shown in the embodiment of the application uses a large amount of experimental data statistics. The reaction time of the user in the period from the time when the user receives the demonstration action to the time when the user makes the corresponding action is 1S, and the preset reaction time duration is configured to be 1S according to the technical scheme shown in the embodiment of the application. For example, the predetermined time points are: 3S, 13S, 23S, 33S, 43S and 53S, the corresponding delayed acquisition time points are: 4S, 14S, 24S, 44S and 54S. At the beginning of the first occurrence of an image frame of the exemplary video, the controllers 14S, 24S, 44S and 54S control the cameras to capture local images respectively after the beginning.

The controller is used for comparing the local image with the demonstration video frame to generate a comparison result; the demonstration video frame is an image corresponding to a local image in the demonstration video, or a standard image frame corresponding to the preset time point in the demonstration video. In the technical solution shown in the embodiment of the present application, the image in the exemplary video may be an image with a logo. The flag may be a time flag, but is not limited to a time flag. The correspondence of the local image to the exemplary video frame may then be determined based on the flag. For example, when the demonstration video is played to 4S, the controller controls the camera to collect the local video, the time mark corresponding to the local video is 3S, and the local video is compared with the target video with the time mark of 3S.

In some embodiments, the exemplary video has joint point data of the exemplary video frame stored therein, the joint point data being preset in advance, and the joint point data may not be preset for other image frames than the exemplary video frame because there is no demand.

In the technical solution shown in the above embodiment, the preset reaction time period is configured to be 1S. However, 1S is a statistical datum, and the reaction duration of a user is 1S in a normal case, but 1S is not applicable to all users, and a preset reaction duration may be set according to requirements in the process of practical application.

Action comparison causes a large processing load through image comparison, and in order to further reduce the data processing amount of the controller, the technical scheme shown in the embodiment of the present application may perform a specific implementation process for comparison only on some "key parts" in the local image and the exemplary video: that is, the alignment of the actions is accomplished by the alignment of the joints.

Before the second video window plays the local image, the controller is further configured to: identifying a joint point in the local image; and comparing the joint points in the local image with the joint points in the demonstration video.

In some embodiments, the controller is configured to control the camera to start to capture the local image in response to the user selecting the start training control in the first display interface. The camera transmits the acquired local image to the controller. A controller identifies a joint point in the local image; in some embodiments, the controller identifies joint points in the local image according to a preset model, the joint points being points corresponding to joints of a human body and points corresponding to a head of the human body, typically the human body including 13 joint positions. The controller marks 13 important bone joint points of the whole body. In this case, the local image labeled with 13 joint positions can be referred to in fig. 11. The 13 joint positions are respectively: left wrist, left elbow, left shoulder, thoracic cavity, waist, left knee, left ankle, head, right wrist, right elbow, right shoulder, right knee, right ankle. However, in some acquired local images, a human body sometimes appears to be partially missing, and only the human body part in the image can be identified at this time.

The controller is further used for comparing the joint points in the local image with the joint points in the demonstration video/demonstration video frame to determine the difference degree between the human body motion in the local image and the human body motion in the demonstration video; and marking the identified joint points in the acquired local image, wherein different colors mark joint points with different action difference degrees.

The implementation manners for determining the difference degree between the human body motion in the local image and the human body motion in the demonstration video are various:

for example, the comparison method may be to compare the position of the joint point of the human body in the local image with the relative position of the joint point of the human body in the demonstration video. The alignment results are obtained based on the difference in relative position. And marking different comparison results by adopting different colors.

For example, the following steps are carried out: the position of the left wrist of the human body in the local image is different from that of the left wrist of the human body in the demonstration video by 10 standard values, and a joint point of the left wrist can be marked by red. The difference between the position of the right wrist of the human body in the local image and the position of the right wrist of the human body in the demonstration video is 1 standard value, and the right wrist joint point can be marked in green.

For another example, the matching degree of the two joint positions can be calculated by the comparison method, and a corresponding result is generated according to the matching degree. Or determining the matching degree of the motion according to the relative position relation between the self-joint points.

The identification and matching of the joints may also be replaced in some embodiments by other implementable means in the relevant art.

In some embodiments, the demonstration joint positions are marked in the demonstration video in advance, and are stored in a local data list together with the demonstration video. The labeling process for the exemplary joint positions is similar to the labeling process shown in the previous embodiments and will not be described in detail here.

In some embodiments, the controller compares the first angle in the local image with the corresponding standard angle to generate a comparison result. The first angle is an included angle between a connecting line of each joint position and an adjacent joint position in the local image and a connecting line of the trunk; the standard angle is the included angle between the connecting line of each joint position and the adjacent joint position in the exemplary video and the connecting line of the trunk.

Wherein the correspondence between the first angle and the standard angle may be generated based on the time stamp. For example, the local image is acquired at 10S, and the standard angle corresponding to the first angle of the left ankle is the angle between the line connecting the left ankle and the adjacent joint position in the image appearing at 10S in the exemplary video and the line connecting the torso.

For example, referring to fig. 12, fig. 12 shows a local image with joint annotation according to some embodiments. For the left wrist portion 1A, the joint position near the left wrist portion 1A is the left elbow 1B, and the included angle between the connecting line of the left wrist portion 1A and the left elbow 1B and the connecting line of the trunk is called as a first angle 1A. By the method, the first angles corresponding to the left elbow, the left shoulder, the left knee, the left ankle, the head, the right wrist, the right elbow, the right shoulder, the right knee and the right ankle can be calculated respectively.

The generation manner of the standard angle may refer to the generation manner of the first angle, which is not described herein again.

The controller calculates the matching degree of the first angle and the corresponding standard angle; and evaluating the completion degree of the user action according to the matching degree.

The technical party shown in the embodiment of the application can calculate the difference between the position of each joint and the standard position, and further helps the completion condition of each part of a user to improve the experience of the user.

In order to help a user further know the completion condition of actions of each part, according to the technical scheme shown in the embodiment of the application, the controller calculates the matching degree of the first angle and the corresponding standard angle, and marks the corresponding color on the joint point according to the area meeting the matching degree.

For example, the following steps are carried out: in some embodiments, the matching degree may be represented by an angle deviation, and the matching result is according to a preset standard deviation value. For angular deviations greater than 15 degrees, the corresponding joint location may be marked red; for a 10-15 degree deviation, the corresponding joint location may be labeled as yellow. For degree deviations below 10 degrees, the corresponding joint position may be marked green.

For example, the difference between the first angle of the left wrist joint in the local image acquired by 10S and the standard angle corresponding to 10S in the exemplary video is 20 degrees, and the corresponding left wrist joint can be marked as red; the difference between the first angle of the corresponding left ankle joint in the local image acquired by 10S and the standard angle corresponding to 10S in the exemplary video is 12 degrees, and the corresponding left wrist joint can be marked as yellow; the first angle of the local image acquired at 10S corresponding to the head differs by 6 degrees from the standard angle corresponding to 10S in the exemplary video, the corresponding left wrist joint may be marked green, and the corresponding annotated local image may be referred to in fig. 13.

Due to the fact that the human body world actions are not matched newly, the technical scheme shown in the embodiment of the application shows a range comparison mode. That is, when the demonstration video is played to the demonstration video frame, the display device acquires a plurality of image frames adjacent to the time point from the local video, and in some embodiments, when the demonstration video is played to the preset time point, the controller selects the plurality of image frames adjacent to the time point from the local video as a first image set, where the first image set at least includes a first local image and a second local image, where the first local image is a local image corresponding to the preset time point, and the second local image is a local image corresponding to a point adjacent to the preset time point.

In some embodiments, the controller calculates a matching degree between the local images in the first image set and the demonstration video frames, takes a comparison result of the local image with the highest matching degree as a comparison result of the time point, and takes the local image with the best matching degree with the demonstration video frame as the local image corresponding to the time point.

In some embodiments it may also be: the controller calculates the matching degree (also called human body action difference degree) of the first local image and the demonstration video frame, when the human body action difference degree is larger than a preset threshold value, the controller screens out an image with the highest matching degree with the demonstration video frame in the first image set as a replacement image, and labels the replacement image according to the comparison result of the replacement image and the demonstration video frame.

For example, for a 10S local image, the first angle corresponding to the wrist joint matches 20% of the standard angle corresponding to 10S in the exemplary video, and the preset matching (preset threshold) is 25%. In this case, the controller determines a first image set of the target data set; the first image set is a local image contained in the target data set during the time period 1S-13S. And respectively calculating the matching degree of the first angle of the wrist joint in each local image and the standard angle of the wrist joint in the 10S demonstration video frame, wherein the matching degree of the data corresponding to 8S and the standard angle of the wrist joint in the 10S demonstration video frame is 80 percent and 80 percent of the highest matching degree. And adjusting the comparison result of the 10S corresponding wrist joint to 80%, labeling the wrist joint by using 80% of colors, and caching the labeled local video by the controller.

In some embodiments, upon completion of the playing of the exemplary video, the controller may control the display to display a practice evaluation interface for presenting the annotated local picture. The exercise rating interface, as shown in fig. 14-1, may simultaneously display the rating of the user, the user's actions, and the normative actions. Wherein the scoring level may be generated based on the degree of matching of the local image to the exemplary video frame.

In some embodiments, the exercise evaluation interface may present the actions of multiple corresponding users in a scrolling manner along with the canonical action. Wherein, the display sequence can be as follows: and displaying the results from low to high according to the scores. Wherein the higher the degree of match with the exemplary video frame, the higher the score.

In other embodiments, the exercise evaluation interface may be displayed in the form shown in fig. 14-1, where the exercise evaluation interface has two display windows, one for displaying the local image corresponding to the time point during the user action and one for displaying the demonstration video frame corresponding to the normative action.

In some embodiments, in order to further reduce the data processing amount of the controller, the 'joint comparison process' may be placed on the server side for execution, and the specific implementation process is as follows:

in some embodiments, before the second video window plays the local image, the controller is further configured to: identifying a joint point in the local image; and sending the joint points in the local image to a server, wherein the server can compare the joint points in the local image with the joint points of the demonstration video frames in the demonstration video, determine the human body motion difference degree between the human body motion in the local image and the demonstration video frames in the demonstration video and generate feedback information to the display device.

In some embodiments, the joint point identification unit in the display device identifies and marks all the images collected by the camera, and displays the images in the second playing window. When the demonstration video is played to the demonstration video frame, the display device uploads the joint point data of the local image acquired at the moment and/or the joint point data of the local image acquired at the adjacent moment to the server to judge the matching degree.

For a comparison between the human body motion in the local image and the human body motion difference in the demonstration video, reference may be made to the above embodiments, which are not repeated herein.

The controller is further configured to receive a feedback message sent by the server, and to mark the identified joint points in the local image according to the feedback message, wherein different colors mark joint points with different degrees of motion difference.

Further, according to the technical scheme shown in the embodiment of the application, the condition that the motion of each joint position is completed is marked by different colors. Different colors are adopted to distinguish the completion conditions of each joint of the user, and the different colors play a striking role. Therefore, the scheme shown in the embodiment of the application is adopted to further help the user to know the completion condition of the action of each part.

In some embodiments, as shown in fig. 14-2, in the second display interface, if the action of the user and the matching action of the exemplary video frame are higher at the time point, a floating layer is added in the second playing window to display a prompt statement to encourage the user.

In some embodiments, as shown in fig. 14-2, in the second display interface, a training progress control is further disposed above the second playing window to show the completion degree of the user action, and the controller controls the completion degree value displayed in the training progress control to be increased when it is detected that the matching degree of the user action and the demonstration action frame is higher than a preset value. And when the matching degree of the user action and the demonstration action frame is detected to be lower than the preset value, controlling the completion degree value displayed in the training progress control to be kept unchanged.

In order to reduce the data processing amount of the server, in some embodiments, the server may process the local image corresponding to the preset time point, and the specific implementation process may be: the controller sends the joint points in the local image to a server, specifically: and the controller caches local images acquired within a preset time period before and after a preset time point when the playing time of the demonstration video reaches the preset time point. And identifying joint point data of the cached local image and sending the identified joint point data to the server.

The process of caching the local image may refer to the above implementation and is not described herein again.

It should be noted that, because the bandwidth occupied by the picture in the transmission process is large, the scheme shown in this embodiment sends the joint point of the local video to the server in order to reduce the bandwidth occupied by the picture in the data transmission process.

In some embodiments, the controller may be further configured to transmit a preset time point to a server while transmitting the identified joint data to the server, so that the server determines image frames (i.e., target images) of the demonstration video for comparison according to the preset time point.

In some feasible embodiments, when the human body action difference degree is greater than a preset threshold, the controller marks the local image and caches a picture of the marked local image and a demonstration video frame corresponding to a preset time point. So as to call the local video with larger action difference when the demonstration video playing is finished.

In some feasible embodiments, the controller controls the display to display an exercise evaluation interface after the playing is finished, and displays the cached image of the labeled local image and the demonstration video frame corresponding to the preset time point on the exercise evaluation interface.

In some embodiments, the demonstration video frames and the corresponding local images at the preset time point are sorted according to the matching degree (or score), and after the demonstration video is played, the demonstration video frames and the corresponding local images at the preset number of time points with low matching degree (or score) are selected for displaying. Illustratively, for example, the exemplary video frames and the corresponding local images at 5 time points are cached according to the matching degree, and after the exemplary video playing is finished, the exemplary video frames and the corresponding local images at 3 time points with a low matching degree (or score) are selected for displaying.

The display mode of the exercise evaluation interface can be referred to the above embodiment.
