Abstract: A projection type billiard system gesture/billiard-rod control system and an implement method thereof. The system comprises an image capture device (7), a projection device (6) and a computer (3). The signal output end of the image capture device (7) is connected to the input end of the computer (3). The input end of the projection device (6) is connected to the output end of the computer (3) and controlled by the computer (3). A hollow billiard lighting lamp (4) and an infrared light supplementary lamp (5) are further provided. The method includes that the computer (3) controls the projection device (6) to project an operation interface comprising various function buttons in a system program on a table surface of a billiard table (8). The computer (3) controls the image capture device (7) to capture images in the scope of the table surface of the billiard table (8) in real time.

Abstract: A projection type billiard ball hitting intelligent auxiliary system and method. The system comprises an image capture device (7), a projection device (6) and a computer (3). The signal output end of the image capture device (7) is connected to the input end of the computer (3). The input end of the projection device (6) is connected to the output end of the computer (3) and controlled by the computer (3). A hollow billiard illuminating lamp (4) and an infrared light supplementary lamp (5) are further provided. The method includes that a billiard environmental model is built in the computer (3). When billiard balls (9) are static, the images of the billiard balls (9) on a billiard table (8) are captured, and the coordinates of the billiard balls (9) are obtained.

Abstract: An infrared projection billiard entertainment system and an implementation method thereof. The system comprises a billiard table (8), an image capture device (7), a projection device (6), a computer (3), a hollow billiard illuminating lamp (4), an infrared light supplementary lamp (5), a projection hanger (1) and an image capture device hanger (2). The computer (3) controls the image capture device (7) to switch to a visible light filter disc and capture the movement image information of billiard balls (9) on the billiard table (8) so as to obtain the information of positions, movement tracks and movement results of the billiard balls (9) in the image information. According to the movement tracks of the billiard balls (9) and/or the movement results of the billiard balls (9), the computer (3) controls the projection device (6) to play corresponding special-effect images on the billiard table (8) and/or the computer (3) plays corresponding sound effects.
