FIG. 3 is a schematic flow chart of a sports film training method according to a second embodiment of the present invention. Referring to FIG. 3 and FIG. 4A and FIG. 1 together, the detailed steps of the motion film training method of the second embodiment will be described below in conjunction with the components of the motion film training system 100.

Step S201 is executed to play the motion movie, and the user starts to perform the action along with the motion movie displayed by the display window 111 of the display device 110, and the image capturing unit 120 simultaneously captures the action performed by the user.

Step S202 is performed, and the processing unit 140 analyzes the image captured by the image capturing unit 120. User image to obtain the user's skeleton message B1. The processing unit 140 transmits the skeleton message B1 to the display device 110 such that the main window of the display window 111 displays the motion movie, and the sub-window displays the skeleton message B1 of the user.

Step S203 is executed, and the processing unit 140 compares the skeleton message B1 with the skeleton file of the motion movie to obtain the similarity. Referring to FIG. 4A, at each time point, when the user performs an action with the motion movie, the similarity between the skeleton message B1 and the skeleton file changes as the time of the movie playing time axis 111C advances, and is similar. Degree curve C1.

Step S204 is executed to determine whether the similarity is lower than the similarity threshold ST. In the present embodiment, the similarity threshold ST is set in advance, for example, 80%, as a threshold value for determining the similarity level. The processing unit 140 can determine whether the similarity reaches the similarity threshold ST. If the similarity is higher than the similarity threshold ST, it returns to step S102. The user continues to act with the motion movie, and the image capturing unit 120 continues to repeatedly acquire the skeleton message, and the processing unit 140 continues to repeat the comparison skeleton message B1 and the skeleton file.

On the other hand, if the similarity is lower than the similarity threshold ST, then step S205 is performed, and the first time point when the similarity starts lower than the similarity threshold ST, the processing unit 140 starts to calculate the similarity lower than the similarity threshold ST The duration. For example, when the moving movie proceeds to the time point T1a of the movie playing time axis 111C, the similarity starts to be lower than the similarity threshold ST, and the processing unit 140 records the time point T1a at which the similarity starts to fall below the similarity threshold ST, And defining the time point T1a as the first time point. Next, the processing unit 140 calculates the duration tm1 whose similarity is lower than the similarity threshold ST from the time point T1a until the similarity starts to be higher than the similarity threshold ST at the time point T2a. That is to say, within the duration tm1, the similarity is lower than the similarity threshold ST.

Step S206 is executed, and the processing unit 140 determines whether the duration is greater than a time threshold. The time threshold may be a predetermined time period for determining whether the similarity is lower than the duration of the similarity threshold ST exceeds the set time threshold, as a determination of whether the user's action is a momentary motion with the motion movie. Inconsistent or user Can't keep up with the judgment indicators of sports videos. The time threshold can be adjusted as the user's age, physical fitness and other physical and mental conditions. If the processing unit 140 determines that the duration is less than the time threshold, the processing unit 140 determines that the similarity passes the threshold, and returns to step S202. The user continues to act along with the played motion movie, and the image capturing unit 120 continues to repeatedly acquire the skeleton message, and the processing unit 140 continues to repeat the comparison skeleton message B1 and the skeleton file.

For example, if the set time threshold is 1 minute, when the motion movie is advanced to the time point T2a of the movie playing time axis 111C, the similarity starts to be higher than the similarity threshold ST, that is, the duration tm1 is between the time points. T1a is between time point T2a. When the processing unit 140 determines that the duration tm1 is less than 1 minute (time threshold), the processing unit 140 determines that the user's motion is inconsistent with the motion movie motion. Accordingly, the processing unit 140 determines that the similarity passes the threshold, and returns to step S202.

On the other hand, if the duration is greater than the time threshold, and it is determined that the similarity is lower than the threshold, step S207 is performed.

For example, when the moving movie proceeds to the time point T1b of the movie playing time axis 111C, the similarity starts to be lower than the similarity threshold ST, and the processing unit 140 records the time point T1b at which the similarity starts to fall below the similarity threshold ST, And defining the time point T1b as the first time point. Next, the processing unit 140 calculates the duration tm2 whose similarity is lower than the similarity threshold ST from the time point T1b until the similarity starts to be higher than the similarity threshold ST at the time point T2b. That is to say, within the duration tm2, the similarity is lower than the similarity threshold ST. The processing unit 140 determines that the duration tm2 is greater than 1 minute (time threshold), and the processing unit 140 determines that the user cannot keep up with the motion movie. Accordingly, the processing unit 140 determines that the similarity does not pass the threshold, and then proceeds to step S207. In step S207, the display device 110 replays the segment of the motion movie whose degree of similarity is lower than the threshold by a replay time point. The user can select a replay time point by replaying the segment of the motion movie whose similarity is below the threshold.

Next, the selection of the replay time point in step S207 of Fig. 3 will be described in detail.

Referring again to FIG. 4A, when the duration is greater than the time threshold, the processing unit 140 If it is determined that the similarity has not passed the threshold, step S207 is immediately followed. The user can select the replay time point as the first time point. Since the duration tm2 is greater than the time threshold, in step S207, the display device 110 can replay the segment of the motion movie whose degree of similarity is lower than the threshold by the time point T1b. Specifically, when the user performs an action with the moving movie, when the moving movie proceeds to the time point T2ba of the movie playing timeline 111C, the processing unit 140 determines that the duration tm2 of the similarity lower than the similarity threshold ST is greater than the time valve. When the value is reached, the time point of the movie playing time axis 111C jumps back to the time point T1b from the time point T2b, wherein the broken line R1 shows the time sequence of the replaying motion movie, please match the contrast line R1. The user can re-train the sports movie of the similar duration tm2 with the similarity threshold T1b, and the user can re-train the time T1b at the time point T1b. Another similarity curve C2 is obtained, thereby increasing the similarity and increasing confidence and learning effectiveness.

In another embodiment, the user may select the replay time point to be the start time point V1s of the video segment V1 including the first time point. Specifically, when the processing unit 140 determines that the duration tm2 of the similarity lower than the similarity threshold ST is greater than the time threshold, in step S207, the time point of the movie playing time axis 111C jumps back from the time point T2b to include the time point. The start time point V1s of the image passage V1 of T2b, wherein the fold line R2 shows the time sequence of the replay motion movie, please match the control fold line R2. The user can re-examine the image segment V1 of the less similar moving movie with the moving movie that is repeatedly played at the starting time point V1s, so that the user can practice again from the time point T1b to obtain another similarity curve C3, thereby improving Similarity increases confidence and learning outcomes.

In another embodiment, the user can select the replay time point as the initial time point S1 of the motion movie. Specifically, when the processing unit 140 determines that the duration tm2 of the similarity lower than the similarity threshold ST is greater than the time threshold, in step S207, the time point of the movie play timeline 111C jumps back to the motion movie from the time point T2b. The initial time point S1, wherein the fold line R3 shows the time sequence of the replay motion movie, please match the contrast line R3. The user can be played back by the start time point V1s The film, practice again and get another similarity curve C4, thereby increasing the similarity and increasing confidence and learning effectiveness.

The time point T1b is the first time point. In step S206, the processing unit 140 determines that the duration tm2 of the similarity lower than the similarity threshold ST is greater than the time threshold, and the moving movie continues to play until the end time point E1 of the moving movie, thereby obtaining the similarity curve C5. In step S207, the display device 110 may jump back to the replay time point from the end time point E1, and play back the segment of the motion movie whose similarity is lower than the threshold.
