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.

Claims

1. An infrared projection billiards entertainment system, comprising:

the image acquisition device (7), the projection device (6), and the computer (3), wherein the signal output end of the image acquisition 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), and hollow billiards light (4), the infrared light supplement lamp (5), the projection hanger (1) and the hanger (2) of the image acquisition device are also equipped;

The infrared light supplement lamp (5) are fixed on the hollow billiards light (4), of which the lighting end is as high as the bottom of the hollow billiards light (4);

the image acquisition device (7) is disposed at the bottom of the image acquisition device (2), of which the head end is aimed at the hollow part center of the hollow billiards light (4) and no under the bottom of the hollow billiards light (4);

the hollow billiards light (4) is fixed above the billiards table(8), so that the image acquisition device (7) is right in front of the center of the billiards table (8);

the projection device (6) and the computer (3) are both installed at the bottom of the projection hanger (1) and hung to the side of the hollow billiards light (4).

2. The system of claim 1, wherein the projection device adopts a projector.

3. The system of claim 1, wherein the image acquisition device (6) adopts the camera with the filter of visible light.

4. The system of claim 1, wherein the image acquisition device (7) can adopt the camera which have both infrared filter and the filter of visible light.

5. The system of claim 1, wherein the hollow billiards light (4) is hung at least 1 meter high above the billiards table (8).

6. A method for the infrared projection billiards entertainment system of claim 1, wherein if the image acquisition device (7) adopts the camera with the filter of visible light, the following steps are included:

The computer (3) controls the image acquisition device (7) to capture the moving image information of the billiards (9) on the billiards table (8) in which there'"'"'s only the real object shone by the infrared supplement light and the visible light projected to the billiards table (8) by the projection device (6) is filtered;

The computer (3) receives the image information, compares and analyzes the background and the previous frame, then acquires the billiards information of positions, tracks and moving results in the image information;

According to the track of the billiards (9) and/or the moving result of the billiards (9), the computer (3) will control the projection device (6) to display the corresponding special-effect pictures on the billiards table (8) and/or play the corresponding sound effects from the computer (3).

7. A method for the infrared projection billiards entertainment system of claim 1, wherein if the image acquisition device (7) adopts the camera with the filter of both infrared and visible light, the following steps are included:

The computer (3) controls the image acquisition device (7) to change into the filter of visible light and capture the moving image information of the billiards (9) on the billiards table (8) in which there'"'"'s only the real object shone by the infrared supplement light and the visible light projected to the billiards table(8) by the projection device (6) is filtered;

The computer (3) receives the image information, compares and analyzes the background and the previous frame, then acquires the billiards (9) information of positions, tracks and moving results in the image information;

The computer (3) controls the image acquisition device (7) to change into the filter of infrared and capture the moving image information of the billiards (9) colors on the billiards table (8);

The computer analyzes the position information of the billiards (9) as well as the image information of the billiards (9) colors, and determines the billiards information of the number/type at each position;

According to the track of the billiards (9), information of the number/type, and/or the moving result of the billiards (9), the computer (3) will control the projection device (6) to display the corresponding special-effect pictures on the billiards table (8) and/or play the corresponding sound effects from the computer (3).

8. The method of claim 6, wherein the moving state of the billiards (9) consists of hitting, moving, stopping, pot and hitting the cushion.

9. The method of claim 6, wherein the method of comparing and analyzing the background is that:
