The invention relates to a projection type billiard hitting intelligent
auxiliary system and method. The projection type billiard hitting intelligent
auxiliary system comprises an image collecting device, a projection device and a computer, the
signal output end of the image collecting device is connected to the input end of the computer, the input end of the projection device is connected with the output end of the computer and controlled by the computer, and a hollow billiard lighting lamp and an
infrared light supplementation lamp are further arranged. The method includes the steps that a billiard
environmental model is built in the computer; when billiards are static, images of the billiards on a billiard table are captured, and coordinates of the billiards are obtained; when a user bends over to enable a billiard rod to be aligned with a cue ball, the coordinates of the two end points of the billiard rod and the hitting directions are captured in real time, and the first billiard which a rod head of the billiard rod points to serves as the cue ball; according to the coordinates of the billiards, to-be-operated tracks of the cue ball and the other billiards are calculated in cooperation with the preset billiard rod hitting force and the preset included angles between the hitting points and the horizontal direction of the billiard rod; the to-be-operated tracks of the cue ball and the other billiards are projected to the billiard table. By means of the projection type billiard hitting intelligent
auxiliary system and method, when the user uses the billiard rod for aligning, the aligning line and the operation tracks of the billiards can be drawn on the billiard table in a projection mode in real time for assisting hitting by the user, and the projection type billiard hitting intelligent auxiliary
system and method are convenient to use and visual.
