Specifically, please refer to FIG. 4. In an embodiment of the present invention, the MCU obtains the human body position information from the video stream image acquired by the camera, and the method of judging the human body position information is as follows: two cameras are defined as camera A12 and camera A12. Camera B13, the predetermined distance S is 0.1 ~ 1m, preferably, can be 0.2m, 0.5m, 0.8m, etc.; the A camera and the B camera are wide-angle lenses, and the viewing angle is above 90 degrees; the camera The viewing angles of camera A and camera B are equally divided into three areas, and the equal division of the viewing angle area is corresponding to the video stream image, and the position in the video stream image of each equal division area is obtained, and finally according to the position of the human body in the video stream image The position determines the area where the shooter is located. Specifically, please refer to FIG. 3. In the figure, the A camera 12 is divided into three areas a, b, and c according to the range of the viewing angle, which are mapped on the picture 14, corresponding to the three areas a, b, and c respectively. If the human body is in the In the area a in the picture, it means that the user is shooting the basketball within the viewing angle of area a. In addition, the distance from the user to the basket can be judged by the size and proportion of the human body in the picture. These data can be stored in the MCU-connected In the memory, it can also be transmitted to the user's handheld terminal. Similarly, the three areas d, e, and f mapped on the picture 15 can be used to calculate the data of the user's shooting practice in the area on the right side of the basket.

In one embodiment of the present invention, the MCU is connected with a wireless communication module, and the user can download the corresponding video through the wireless communication module after passing the authentication.

In one embodiment of the present invention, an APP is set on the user's handheld terminal, and the APP includes a verification trigger module, a display module, a data receiving and processing module, a video playback module, and a circle of friends sharing module; In order to trigger the connection between the handheld terminal and the basketball stand, the connection method is to send a password to the basketball stand for verification by entering a password on the handheld terminal; the display module is used to display the data processed by the data receiving and processing module, The data includes the number of goals in the basket, the time point of the goal and the position of the goal; the video playback module is used to play the video information received by the data receiving and processing module, and the video playback module has slow motion playback, pause, fast forward and picture Interception function: the circle of friends sharing module is used to share the video and screenshots played by the video playing module in the circle of friends.

In an embodiment of the present invention, the distance between the user and the basket is judged by the size and proportion of the human body in the picture.

In an embodiment of the present invention, the camera A and camera B can be linked and controlled, and have a focal length adjustment function; the way of the linked control includes: defining the initial value of the camera A and the camera B, in the MCU from the camera A or the camera When the area where the shooter is located in B, the MCU controls the camera corresponding to the area to zoom in on the camera to perform a close-up of the shooter's posture; and controls another camera to rotate to close-up the shooter's posture from another angle , after the close-up ends, the MCU controls the two cameras to restore the initial values, which include the initial positions and initial focal lengths of the cameras. These collected close-ups can be sent to the user's handheld terminal according to the user's request, and the user can analyze these videos through the APP.

In order to avoid the waste of storage space and the validity of the transmitted video data, in an embodiment of the present invention, the MCU automatically cuts and deletes the shaking video recorded by camera A and camera B after the basketball touches the frame.

It should be emphasized that the camera mentioned in the method of the present invention not only has video recording and picture acquisition, but also cleverly judges the shooting position of the human body relative to the basket through the division of basketball shooting areas and the characteristics of the human body corresponding to the picture. , because basketball shooting is very necessary for shooting training in different positions, the present invention just solves this problem, and the distance between the person and the basket can be judged through the body size ratio of the human body in the picture, so as to form The training data and the ability to improve one's own technique through the playback of this data and video after training provide the greatest degree of help. In addition, the method of the present invention proposes that the shooting training device interacts with the user's handheld terminal. In the field of shooting practice, it is not only convenient to use, but also can provide remote guidance for coaches.

The above descriptions are only preferred embodiments of the present invention, and all equivalent changes and modifications made according to the scope of the patent application of the present invention shall fall within the scope of the present invention.
