However, those of ordinary skill in the art will understand that in various embodiments of the present application, numerous technical details have been set forth in order to provide a better understanding of the present application. However, the claimed application may be practiced without these specific details and with various changes and modifications based on the following embodiments.
The first embodiment of the present application relates to a demonstration video display method, and the core of the present embodiment is that the method includes: the method comprises the steps of obtaining follow-up videos of a plurality of users following preset demonstration videos, determining action difficulty of each user in the follow-up videos, obtaining sub-demonstration videos matched with the action difficulty of each user from a preset demonstration video database, obtaining a plurality of sub-demonstration videos, displaying the sub-demonstration videos by a terminal, wherein each user can see the sub-demonstration videos matched with the action difficulty of the user, and the action types of the sub-demonstration videos in the demonstration video database are the same as those of the preset demonstration videos but the action difficulties are different, so that the sub-demonstration videos displayed by the terminal can be distinguished on the basis of the same action, each sub-demonstration video is attached to the action difficulty of different users, and the interestingness of the user following the action of the demonstration videos is improved.
The implementation details of the demonstration video presentation method of the present embodiment are specifically described below, and the following description is provided only for convenience of understanding, and is not necessary to implement the present embodiment.
The flow chart of the demonstration video presentation method in the present embodiment is shown in fig. 1:
step 101: and acquiring heel training videos of a plurality of users following the preset demonstration video.
Specifically, the user can play a preset demonstration video by using a terminal provided with a heel exercise APP, and the terminal can acquire real-time heel exercise video of the user through a camera of the mobile phone, the tablet or the television; the method can also play the preset demonstration video by utilizing the shared screen of the terminal provided with the heel-exercise APP, and acquire the real-time heel-exercise video of the user through the camera of the terminal. It is worth to say that, if the terminal is provided with the peripheral camera, also can acquire the real-time follow-up video of user through the peripheral camera. And the terminal uploads the acquired real-time heel training video to a server.
Step 102: it is determined whether the user is a registered user. If the determination is not yes, the process proceeds to step 103, and if the determination is yes, the process proceeds to step 106.
Specifically, the preset demonstration video is generated according to the history training record of a registered user in the plurality of users, and the preset demonstration video is matched with the action difficulty of the registered user. The registered user is a registered user prestored on a follow-up APP server, personal information of the registered user is stored on the server, and the personal information at least comprises: face data uploaded by a user, heel training targets, action difficulties and the like. Generally, when a registered user performs a follow-up exercise according to a preset demonstration video, a family or a friend of the registered user may want to join together to perform a motion along with the preset demonstration video, but the family or the friend of the registered user may not belong to the registered user who follows the APP, so that the server does not have personal information of the family or the friend, and it is difficult to provide a sub-demonstration video matching with the motion difficulty of the family and the friend.
In this embodiment, the real-time heel-and-toe training video uploaded to the server is subjected to face recognition, and when more than two faces in the real-time heel-and-toe training video are recognized, each face recognized is compared with the face image uploaded to the server to determine whether the user is a registered user. If it is determined that the user is not a registered user, step 103 is entered: determining matching degree of heel-exercise actions of each user in a plurality of users in the heel-exercise video and teaching actions in a preset demonstration video; if it is determined that the user is a registered user, step 106 is entered: and taking the preset demonstration video as a sub-demonstration video matched with the action difficulty of the registered user.
Step 103: and determining the matching degree of the heel-exercise action of each user in the heel-exercise videos and the teaching action in the preset demonstration videos.
In this embodiment, determining a matching degree between a heel-exercise action of each of a plurality of users in a heel-exercise video and a teaching action in a preset demonstration video includes: comparing teaching actions of the heel-exercise video with heel-exercise actions of a preset demonstration video, and determining the percentage of the number of completed heel-exercise actions, the percentage of duration and the percentage of action amplitude of the user; and determining the matching degree of the heel-exercise action of the user and the teaching action in the preset demonstration video according to the completion number percentage, the duration percentage and the action amplitude percentage of the heel-exercise action.
Specifically, the server draws the body contour and main joints of the user according to the acquired real-time heel-training video of the user, so that the body state and the motion of the user are analyzed, the body state and the motion of each user in the heel-training video are compared with the body state and the motion of the user in a preset demonstration video, and the completion number percentage, the duration percentage and the motion amplitude percentage of the current motion of each user in the heel-training video are determined. In one example, the preset demonstration video played at present is abdominal muscle training video, the current action is abdomen rolling, the standard action of abdomen rolling in the preset demonstration video is a group of 10 actions, if the group of actions of the user in follow-up video is completed only by 5, the number percentage of the completed actions is 50%; if the motion amplitude of the abdomen rolling standard motion in the preset demonstration video is 140 degrees (the included angle between the upper half trunk and the lower half trunk of the abdomen rolling of the user), if the motion amplitude of the user in the follow-up video is 160 degrees, the error is 14%, and the motion amplitude percentage is 100% -14% = 86%; if the current action is a flat panel support, the standard time of the action in the preset demonstration video is 20 seconds, and the duration percentage is 75% when the user flat panel support in the follow-up video is kept for 15 seconds.
Determining the matching degree of the follow-up action of the user and the teaching action in the preset demonstration video according to the completion number percentage, the duration percentage and the action amplitude percentage of the current action, and giving corresponding weights to the three parameters to determine the matching degree in practice, for example: the weights of the three parameters can be set to be the same, and the matching degree is embodied by the average value of the three percentages, specifically: (50% +86% + 75%)/3=70%.
Step 104: and determining the action difficulty of each user according to the action difficulty and the matching degree of the preset demonstration video.
Specifically, the server stores in advance a correspondence relationship between the action difficulty and the matching degree, for example, as shown in the following table 1:
| percentage of matching degree | Difficulty of action |
| 85％≤X≤100％ | Five stages: currently preset video difficulty of demonstration |
| 70％≤X＜85％ | Four stages: currently preset demonstration video difficulty down-regulating one level |
| 50％≤X＜70％ | Three stages: currently preset demonstration video difficulty down-regulating two stages |
| 30％≤X＜50％ | And (2) second-stage: currently preset demonstration video difficulty down-regulating three-stage |
| X＜30％ | First-order: currently preset demonstration video difficulty down-regulating four stages |
After the matching degree of the user is determined, the action difficulty of the user can be determined according to the determined matching degree and the corresponding relation. For example: assuming that the matching degree of the abdominal muscle training of the user is 75%, the action difficulty of the user can be determined to be four-level, and the action difficulty of the current preset demonstration video is adjusted by one level.
Step 105: and acquiring sub-demonstration videos matched with the action difficulty of each user from a preset demonstration video database.
Specifically, a demonstration video library is pre-stored in the server, a plurality of sub-demonstration videos are arranged on the demonstration videos of the same set of actions according to different difficulties, the demonstration videos of the same set of actions are pre-stored in the same demonstration video sub-library, the demonstration videos in the same demonstration video sub-library have the same time axis, the action contents are the same, and the difference is only that the amplitude, the number and the duration of the actions are different.
In one example, the presentation video library pre-stored by the server may be as shown in table 2 below, and may include: abdominal muscle training video sub-libraries, leg training video sub-libraries, back training video sub-libraries, and the like. For example, in the abdominal muscle training video sub-library, a plurality of sub-demonstration video files with difficulty ranging from level 1 to level N (from easy to difficult) are provided, and the total duration of each video file is the same, and the included actions are the same, such as a first action is a rolling abdomen, a second action is a flat plate support, and the like. For the demonstration video of abdominal muscle training, if the difficulty of the demonstration video is five, the number of first action curls can be 20; if the difficulty of the demonstration video is one level, the first action abdomen rolling time can be 3, the rest time is the rest time, and the starting time points of the second action flat plate support are consistent.
Thus, the server selects the sub-demonstration video which is matched with the action difficulty of the user from the current demonstration video sub-library from the demonstration video library.
Step 106: and taking the preset demonstration video as a sub-demonstration video matched with the action difficulty of the registered user.
Specifically, if the user is determined to be a prestored registered user, the server side can directly use the preset demonstration video as the sub-demonstration video matched with the action difficulty of the registered user, and a new sub-demonstration video is not required to be provided for the registered user because the preset demonstration video is matched with the action difficulty of the registered user.
Step 107: and transmitting the plurality of sub-presentation videos to the terminal so that the terminal can present the plurality of sub-presentation videos.
Specifically, sub-demonstration videos matched with the action difficulty of the user are obtained according to the action difficulty of each user, so that a plurality of sub-demonstration videos are obtained, and the sub-demonstration videos are displayed on the same display interface in a split screen mode. When the actual split screen display is performed, the positions of the corresponding demonstration videos on the display interface can be determined according to the orientations of the registered user, the non-registered user and the camera, for example, the registered user is positioned at the left side of the screen, and the demonstration videos of the registered user are displayed at the left side of the split screen; and if the non-registered user is positioned on the right side of the screen, displaying the demonstration video of the non-registered user on the right side of the split screen.
Therefore, the method can realize that the action types of the sub-demonstration videos are the same but the action difficulties are different, and the user can watch the demonstration videos with different action difficulties, but the actions are the same and the time axis is the same, so that the distinction of the action difficulties can be realized on the basis of the same action, the action difficulties of the user can be more attached, and the interest of the user following the action of the demonstration videos can be improved.
Compared with the prior art, the embodiment of the application provides a demonstration video display method, which comprises the following steps: the method comprises the steps of obtaining follow-up videos of a plurality of users following preset demonstration videos, determining action difficulty of each user in the follow-up videos, obtaining sub-demonstration videos matched with the action difficulty of each user from a preset demonstration video database, obtaining a plurality of sub-demonstration videos, displaying the sub-demonstration videos by a terminal, wherein each user can see the sub-demonstration videos matched with the action difficulty of the user, and the action types of the sub-demonstration videos in the demonstration video database are the same as those of the preset demonstration videos but the action difficulties are different, so that the sub-demonstration videos displayed by the terminal can be distinguished on the basis of the same action, each sub-demonstration video is attached to the action difficulty of different users, and the interestingness of the user following the action of the demonstration videos is improved.
The above steps of the methods are divided, for clarity of description, and may be combined into one step or split into multiple steps when implemented, so long as they include the same logic relationship, and they are all within the protection scope of this patent; it is within the scope of this patent to add insignificant modifications to the algorithm or flow or introduce insignificant designs, but not to alter the core design of its algorithm and flow.
