The number of elongated lenses 2 is equal to the number of the sliders 6 below, the upper end is connected to the slider 6 above, and the lower end is connected to the slider 6 below, after all the lenses 2 are spliced is larger than the width of the through-hole 4 . The communicator is used to receive the teacher guidance video sent by the teacher terminal. The display mechanism is used to play the teacher's guidance video, and is arranged inside the box 1 . The central processor sends the teacher's guidance video received by the communicator into the display mechanism, and after playing the set number of times, controls the driving mechanism to work so that the lens 2 blocks the port 4 . The power supply device is respectively electrically connected with the driving mechanism, the communicator, the display mechanism and the central processing unit.

In the above technical solution, when in use, the user turns on the power supply device of the present invention, so that the power supply device supplies power for the driving mechanism, the communicator, the display mechanism and the central processing unit. The lens 2 is located at the port 4, and the port 4 is blocked, so that the present invention can be used as a mirror for normal training. At the same time, the communicator receives the teacher's instruction video sent by the teacher terminal in real time. When the terminal sends the teacher's guidance video, the central processor controls the driving mechanism to drive the movement of the slider 6, so that several long-shaped lenses 2 do not block the port 4, and the central processor puts the teacher's guidance video sent by the teacher's terminal into the display. It is played in the institution. After playing the set number of times, it is generally played three or four times. At this time, the user can follow the teacher's instructional video to learn and practice. If the customer needs to practice in the traditional way, that is, look in the mirror When practicing, the central processing unit controls the drive mechanism to drive the movement of the slider 6 so that the plurality of elongated lenses 2 block the opening 4 . In this way, the present invention can be used to perform self-exercise at home when some unavoidable event occurs that causes the trainer to perform individual exercises at home.

In this embodiment, the display mechanism includes: a support plate 7 and several indicator lights 14 .

The pixels of each frame in the moving image are displayed by the indicator lights 14 respectively.

In the above technical solution, the difference between the ratio between the teacher and the student is obtained through the height of the teacher and the height of the student. When displaying, the size of the teacher's action image is adjusted according to the ratio between the height of the teacher and the height of the student. In the image displayed by the indicator light 14, the value of its height is completely consistent with the height of the student. At this time, it can be considered that its body shape is consistent with the student's body shape, so that when the student is watching, he can know more clearly own actions.

According to the sequence of frames, the pixel map of the device generates the actual video of the student, and superimposes the actual video of the student and the action image of the student and sends it to the student terminal.

In the above-mentioned technical scheme, the movement of the student is detected by several distance detectors 13 respectively in the lattice, in the present invention, all the distance detectors 13 detect the movement of the student at the same time to obtain a video frame, And the pixel map is generated according to the detection result of the distance detector 13. Finally, the pixel map of each frame is used to generate the actual video of the students according to the order of the frames, so that the actual video of the students during training can be obtained. The actual video of the student and the action image of the student are superimposed and sent to the student terminal, so that the student can watch the difference between his own action and the standard action on the student terminal.

Meanwhile, in this embodiment, the indicator light 14 is in a ring shape, and the distance detector 13 is located in the center of the indicator light 14 . In this way, the data detected by the distance detector 13 can be more accurate, so that the actual video of the student in the later stage and the action image of the student can be completely overlapped when superimposed.
