Detailed Description

For the purposes of making the objects, technical solutions and advantages of the exemplary embodiments of the present application more apparent, 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 apparent that the described exemplary embodiments are only some embodiments of the present application, but not all embodiments.

For convenience of use, various external device interfaces are usually provided on the display device, so as to connect different peripheral devices or cables to realize corresponding functions. When the high-definition camera is connected to the interface of the display device, if the hardware system of the display device does not have the hardware interface of the high-pixel camera for receiving the source code, the data received by the camera cannot be presented on the display screen of the display device.

Also, due to the hardware structure, the hardware system of the conventional display device only supports one path of hard decoding resource, and usually only supports video decoding with a resolution of 4K at maximum, so when video chat while watching the network television is to be implemented, in order not to reduce the definition of the network video picture, it is necessary to decode the network video using the hard decoding resource (typically, GPU in the hardware system), and in this case, only the video chat picture can be processed in such a way that the video is soft decoded by a general processor (e.g. CPU) in the hardware system.

The soft decoding is adopted to process the video chat pictures, so that the data processing load of the CPU is greatly increased, and when the data processing load of the CPU is too heavy, the problems of picture blocking or unsmooth can occur. Furthermore, due to the data processing capability of the CPU, when the video chat frame is processed by adopting the soft decoding of the CPU, the multi-channel video call cannot be realized, and when the user wants to perform video chat with a plurality of other users at the same time in the same chat scene, the situation of access blocking occurs.

Based on the above-mentioned aspects, to overcome the above-mentioned drawbacks, the present application discloses a dual hardware system architecture to implement multiple video chat data (at least one local video).

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

In some embodiments, the second playing window directly plays the local video acquired 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 training start control in the display interface by a user, acquire an demonstration video, raise and start a camera, wherein the camera is used for acquiring a local pattern; and controlling a first playing window of the display to play the demonstration video, and displaying the local image by a second playing window of the display. Therefore, according to the technical scheme, 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 motion of the user through comparison of the displayed contents in the two windows in the training process, so that the experience of the user is improved.

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

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

In some embodiments, there are a variety of implementations of capturing local images.

For example, the controller may control the camera to capture a local image when the demonstration video is played to a preset point in time; and then comparing the local image acquired by the camera with a 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 controls the camera to acquire a local image. The preset time point may be a preset time point from when the first image appears in the demonstration video to when the last frame image appears in the demonstration video every interval T time. The preset time point may also be generated based on the content of the exemplary video, where each action node in the content of the exemplary video serves as a preset time point. For example, for an exemplary video, the first image appears with a start of 3S and a t time of 10S, the exemplary video is 53S in length. The corresponding preset time point is as follows: 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 sent out in playing time, local images are collected.

For another example, the camera is always in an on state, and the local video is recorded in real time and sent to the controller. The controller can extract a corresponding local image in the acquired local video at a preset time point; and then comparing the extracted local image with a pre-stored demonstration video frame to further 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 time point from when the first image appears in the demonstration video to when the last frame image appears in the demonstration video every interval T (i.e. the time when the demonstration action appears). The preset time point may also be generated or pre-marked based on the content of the exemplary video, where each action node in the content of the exemplary video serves as a preset time point. For example, for an exemplary video, the first image appears at a starting point of 3S, and the predetermined time point is: 3S, 16S, 23S, 45S and 53S, the controller will capture a local image in the local video when the video is released to play to 3S, 16S, 23S, 45S and 53S. It is known that the occurrence time of the demonstration action is arbitrary, and the acquisition of the image to be compared is triggered according to the tag or the time point for identifying the demonstration action.

Typically, after watching the coaching action of the demonstration video, the user simulates the coaching action to take a corresponding action. The user naturally has a certain delay from the time the demonstration action is received to the time the corresponding action is made. In order to counteract the delay, the technical solution shown in the embodiment of the present application shows a "delayed image acquisition method". In this embodiment, a concept of a delayed acquisition time point is introduced, where the delayed acquisition time point=a preset time point+a preset reaction duration. And when the demonstration video is played to the delayed acquisition time point, the controller controls the camera to acquire the local video.

The technical solution shown in the embodiments of the present application uses an excessive amount of experimental data statistics. The reaction time of the user is 1S in the period from the receiving of the demonstration action to the making of the corresponding action, and the preset reaction time is configured to be 1S according to the corresponding technical scheme shown in the embodiment of the application. For example, the preset time point is: 3S, 13S, 23S, 33S, 43S and 53S, the corresponding delayed acquisition time points are: 4S, 14S, 24S, 44S and 54S. The first occurrence of an image frame in an exemplary video is taken as a starting point, after which 14S, 24S, 44S and 54S controllers control the cameras to acquire local images, respectively.

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 the 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 sign. The flag may be a time-stamp, but is not limited to a time-stamp. The correspondence of the local image to the exemplary video frame may then be determined based on the flag. For example, when the exemplary video is played to 4S, the controller controls the camera to collect the local video, the time stamp corresponding to the local video is 3S, and the local video is compared with the target video with the time stamp of 3S.

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

In the technical solution shown in the above embodiment, the preset reaction duration is configured to be 1S. However, 1S is a piece of statistical data, and the reaction duration of the user is usually 1S, but 1S is not suitable for all users, and the preset reaction duration can be set according to the needs in the actual application process.

The action comparison can cause a larger processing burden 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 application can only compare specific implementation processes for some key parts in the local image and the demonstration video: that is, the comparison of the motions is accomplished by the comparison of the joint points.

The controller is further configured to, prior to the second video window playing the local image: identifying an articulation point in the local image; comparing the nodes in the local image with the nodes in the exemplary video.

In some feasible embodiments, the controller is configured to respond to the selection of the training start control in the first display interface by a user, and the controller controls the camera to start so that the camera acquires the local image. The camera transmits the acquired local images to the controller. The controller identifies an articulation point in the local image; in some embodiments, the controller identifies the joint points in the local image according to a preset model, wherein the joint points are points corresponding to joints of a human body and points corresponding to the head of the human body, and the human body generally comprises 13 joint positions. The controller marks 13 important bone joint points of the whole body. The local image labeled with 13 joint bits can refer to fig. 11. The 13 joint positions are respectively: left wrist, left elbow, left shoulder, chest, waist, left knee, left ankle, head, right wrist, right elbow, right shoulder, right knee, right ankle. However, in some acquired local images, the human body sometimes has a partial missing condition, 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 and determining the difference degree of human body actions in the local image and the human body actions in the demonstration video; the identified nodes are marked in the acquired local images, wherein the nodes with different action difference degrees are marked by different colors.

The implementation ways of 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 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 exemplary video. And obtaining a comparison result based on the difference of the relative positions. Different comparison results are marked by different colors.

Illustrating: the position of the left wrist of the human body in the local image is different from the position of the left wrist of the human body in the demonstration video by 10 standard values, and a red mark of the left wrist articulation point can be adopted. The position of the right wrist of the human body in the local image is different from the position of the right wrist of the human body in the demonstration video by 1 standard value, and the right wrist joint point can be marked in a green mode.

For another example, the matching degree of the two joint positions can be calculated by the comparison mode, and corresponding results are generated according to the matching degree. Or determining the matching degree of the actions according to the relative position relation between the self-closing nodes.

The identification and matching of the nodes of interest may also be replaced in some embodiments by other realizable means in the related art.

In some embodiments, the exemplary joint bits are marked in advance in the exemplary video and stored with the exemplary video in a local data list. The labeling process of the exemplary joint bits is similar to that shown in some of the embodiments described above and will not be described in detail herein.

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

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 then the standard angle corresponding to the first angle of the left ankle is the angle between the line of the left ankle and the adjacent joint and the line of the trunk in the image appearing at 10S in the exemplary video.

For example, referring to fig. 12, fig. 12 is a diagram illustrating a local image annotated with joints according to some embodiments. For the left wrist 1A, the joint adjacent to the left wrist 1A is the left elbow 1B, and the included angle between the connecting line of the corresponding left wrist 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 generating manner of the standard angle may refer to the generating manner of the first angle, which is not described herein.

The controller calculates the matching degree of the first angle and the corresponding standard angle; and according to the matching degree, the user action completion degree can be evaluated.

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

In order to help a user further understand the situation that actions of all parts are completed, according to the technical scheme shown in the embodiment of the application, a controller calculates the matching degree of a first angle and a corresponding standard angle, and corresponding colors are marked on joint points according to the area in which the matching degree accords with.

Illustrating: in some embodiments, the matching degree may be represented by an angular deviation, and the matching result is according to a preset standard deviation value. For angular deviations greater than 15 degrees, the corresponding joint position may be marked red; for 10-15 degree deviations, the corresponding joint positions may be marked yellow. For degree deviations below 10 degrees, the corresponding joint bit may be marked green.

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

Because of new mismatch of human world actions, the technical scheme shown in the embodiment of the application shows a 'range' comparison mode. That is, when the exemplary video is played to the exemplary 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 exemplary video is played to the preset time point, the controller selects the plurality of image frames adjacent to the time point in the local video as a first image set, where the first image set includes at least 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 the preset time point.

In some embodiments, the controller calculates the matching degree of the local image in the first image set and the exemplary video frame, uses the comparison result of the local image with the highest matching degree as the comparison result of the time point, and uses the local image with the best matching degree with the exemplary 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 as human body action difference degree) between 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 the image with the highest matching degree with the demonstration video frame from the first image set as a replacement image, and marks the replacement image according to the comparison result of the replacement image and the demonstration video frame.

For example, for a 10S acquired local image, the first angle of 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 within the target dataset for a period of time 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 calculated result is that 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 the highest matching degree is 80 percent. And adjusting the comparison result of the wrist joint corresponding to 10S to 80%, marking the wrist joint by using 80% of the colors used for comparison, and caching the marked local video by the controller.

In some embodiments, upon completion of playing the demonstration video, the controller may control the display to display an exercise rating interface for displaying the annotated local picture. The exercise evaluation interface may refer to fig. 14-1, where the scoring level of the user, the actions of the user, and the canonical actions may be displayed simultaneously on the exercise evaluation interface. Wherein the scoring level may be generated based on a degree of matching of the local image to the exemplary video frame.

In some embodiments, the exercise rating interface may present actions of a plurality of corresponding users in a scrolling manner as well as canonical actions. The sequence of the display can be as follows: and displaying the scores in sequence from low to high. Wherein the higher the degree of matching with the exemplary video frame, the higher the score.

In other embodiments, the exercise evaluation interface may be presented in a form as 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 in the user action and one for displaying the exemplary video frame corresponding to the canonical action.

In some embodiments, to further reduce the data processing amount of the controller, the 'node comparison process' may be performed at the server, which specifically implements the process:

In some embodiments, before the second video window plays the local image, the controller is further configured to: identifying an articulation point in the local image; and transmitting the joint points in the local image to a server, wherein the server can compare the joint points in the local image and the joint points of the demonstration video frames in the demonstration video, determine the difference degree of human body actions in the local image and the human body actions of the demonstration video frames in the demonstration video and generate feedback information to the display equipment.

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

The comparison method of the human motion difference degree in the local image and the human motion difference degree in the demonstration video can refer to the above embodiment, and will not be described herein.

The controller is further configured to receive a feedback message sent by the server, and label the identified nodes in the local image according to the feedback message, wherein different colors label the nodes with different action difference degrees.

Further, according to the technical scheme shown in the embodiment of the application, the situation that the actions of all joint positions are completed is marked by adopting different colors. Different colors are adopted to distinguish the completion condition of each joint of the user, and the different colors play a striking role. It can be seen that the solution shown in the embodiment of the present application further helps the user to know the situation that the actions of each part are completed.

In some embodiments, as illustrated in fig. 14-2, in the second display interface, if the user's action and the matching action of the exemplary video frame are higher at that point in time, a floating layer is added to the second play window to display a prompt sentence 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 when the controller detects that the matching degree between the user action and the demonstration action frame is higher than the preset value, the controller controls the completion degree value displayed in the training progress control to be increased. And when detecting that the matching degree of the user action and the demonstration action frame is lower than a preset value, controlling the completion degree value displayed in the training progress control to be 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 point in the local image to a server, specifically: and the controller caches the local images acquired in a preset time period before and after the preset time point when the playing time of the demonstration video reaches the preset time point. And identifying node data of the cached local image and transmitting the identified node data to a server.

The process of buffering the local image may be referred to the above implementation and will not be described herein.

It is noted that, since the bandwidth occupied by the picture in the transmission process is large, the solution shown in this embodiment transmits the articulation point of the local video to the server in order to reduce the bandwidth occupied in the data transmission process.

In some embodiments, the controller may be further configured to send the identified joint point data to a server while sending a preset point in time to the server, such that the server determines an image frame (i.e., a target image) of the exemplary video for comparison according to the preset point in time.

In some feasible embodiments, the controller marks the local image and caches the marked picture of the local image and the demonstration video frame corresponding to the preset time point when the difference degree of the human actions is larger than the preset threshold value. So that at the end of the exemplary video play, local video with a large difference in motion is invoked.

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

In some embodiments, the exemplary video frames and the corresponding local images at the preset time points are ranked according to the matching degree (or score), and after the playing of the exemplary video is finished, the exemplary video frames and the corresponding local images at the preset number of time points with low matching degree (or score) are selected for display. For example, exemplary video frames and corresponding local images at 5 time points are buffered according to the matching degree, and after the exemplary video playing is finished, 3 time points with low matching degree (or scoring) are selected for display.

The display mode of the exercise evaluation interface can refer to the embodiment.
