First Claim
1. An intelligent projection assist system for hitting of the billiards, comprising:
- The computer (3),image acquisition device (7) of which the signal output end is connected to the input end of the computer (3), and projection device (6) of which the input end is connected to the output end of the computer (3) and controlled by the computer (3), wherein hollow billiards light (4) and the infrared light supplement lamp (5) are also equipped;
The lens of the image acquisition device (7) where a visible light filter is added , and 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) configured for capturing the image information of the billiards table (8), the billiards (9) and the cue (10);
The infrared light supplement lamp (5) are fixed on the hollow billiards light (4), of which lighting end is as high as the bottom of the hollow billiards light (4) configured for infrared lighting on the billiards table (8) and filtering the visible light in the image acquisition device (7);
The computer (3) are used for acquiring the image information captured by the image acquisition device (7) shone in the light of the infrared light supplement lamp (5), getting the track information of the billiards to run according to the coordinate of the billiards, that of the two ends of the cue, the hitting direction, hitting strength and the hitting angel received, and projecting the track information of the billiards with images to the corresponding position of the billiards table (7) through the projection device (6);
The hollow billiards light(4) is at the top of the billiards table (8), so that the image acquisition device (7) is right in front of the center of the billiards table (8).

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. When a user bends over to aim a billiard rod (10) at a cue ball, the coordinates of two end points and the hitting direction of the billiard rod (10) are captured in real time, and the first ball which the rod head of the billiard rod (10) points to serves as the cue ball. According to the coordinates of the billiard balls (9), to-be-operated tracks of the cue ball and the other target balls are calculated in cooperation with the preset hitting force of the billiard rod (10) and the angles between the hitting points and the horizontal direction of the billiard rod (10). The to-be-operated tracks of the cue ball and the other balls are projected on the billiard table (8).
