Non-contact basketball pass training device based on interactive projection system and method for acquiring basketball passing success rate

[0025] Specific implementation mode one, combination Figure 1 to Figure 3 To explain this specific embodiment, a non-contact basketball passing training device based on an interactive projection system, which includes a wall hitting, an interactive projection system 1, a curtain 20, a distance sensor 2 and a control module 10;

[0026] The curtain 20 is covered and laid on the hitting wall; the distance sensor 2 is fixed to the hitting wall;

[0027] The projection control signal input terminal of the interactive projection system 1 is connected to the projection control signal output terminal of the control module 10;

[0028] The pass target point collection signal output terminal of the interactive projection system 1 is connected to the pass target point collection signal input terminal of the control module 10;

[0029] The distance signal output terminal of the distance sensor 2 is connected to the distance signal input terminal of the control module 10.

[0030] Working principle: The working principle of the interactive projection system is to first capture and shoot the target image (such as the participant) through the capture device (sensor), and then analyze it by the image analysis system to generate the motion of the captured object. The motion data is combined The real-time video interactive system enables a closely integrated interactive effect between the participants and the screen.

[0031] The composition of the interactive part of the interactive projection system: the interactive part is composed of four parts. The first part: the signal acquisition part, which captures and shoots according to the interactive needs. The capture devices include infrared sensors, video cameras, thermal cameras, etc.; the second part : The signal processing part, which analyzes the data collected in real time, and the generated data is connected with the virtual scene system; the third part: the imaging part, the image is presented in a specific position using a projector or other imaging equipment, and the image is displayed In addition to projectors, plasma displays, liquid crystal displays, and LED screens can all be used as carriers of interactive images. The fourth part: auxiliary equipment, such as transmission lines, installation components, audio devices, etc.

[0032] The invention uses the passing target point as the target image to realize non-contact basketball passing training, and by capturing and shooting the basketball passing, the control module performs system analysis to obtain the statistical value of the return accuracy.

[0033] The invention uses the interactive projection system to indicate the passing target point, so that the player can carry out the pass training purposefully; simulate the on-the-spot environment, thereby effectively improving the player's reaction speed and ability to adapt to changes, and reducing the player's reaction time. The invention is suitable for basketball passing training.

[0034] The invention can effectively improve the player's reaction ability and improve the player's predictive ability; and can carry out targeted intensive training, thereby greatly improving the player's passing training effect. Especially suitable for passing training for point guard players.

[0035] The second embodiment is that the difference between this embodiment and the non-contact basketball passing training device based on the interactive projection system described in the first embodiment is that it also includes a switch pad 3, which is set in At the front of the wall, the switch pad signal output terminal of the switch pad 3 is connected to the switch pad signal input terminal of the control module 10.

[0036] In this embodiment, the switch pad 3 is set in front of the hitting wall. When the player passes the ball, he first step on the switch pad 3, and the control module 10 controls the interactive projection system to work after receiving the switch signal of the switch pad 3.

[0037] Embodiment 3 The difference between this embodiment and the non-contact basketball passing training device based on the interactive projection system described in Embodiment 1 or 2 is that it also includes a remote control and a wireless signal receiving module 42. The remote controller is composed of a key input circuit, a decoding circuit and a wireless signal transmitting module 41. The wireless signal transmitting module 41 and the wireless signal receiving module 42 realize data interaction through wireless signals. The signal output end of the key input circuit is connected to the decoding The signal input end of the code circuit, the decoded signal output end of the decoding circuit is connected to the signal input end of the wireless signal transmitting module 41, and the signal output end of the wireless receiving module 42 is connected to the signal input end of the control module 10.
