Billiard repositioning method based on image matching technology

Abstract

The invention relates to a billiard repositioning method based on an image matching technology in a computer billiard assistant judging system. The method is realized in the computer billiard assistant judging system; the system comprises a camera, a Snooker billiard table, a video capture device and a computer; and the camera is arranged above the center of the billiard table surface. The method comprises the following steps of judging whether the billiard balls are displaced and repositioning displaced billiard balls. The invention has the beneficial effects of: 1. having memory function, storing each frame image captured in the billiard game, being capable of replaying any frame picture in the game; 2. having fast speed for repositioning judgment and operation and realizing real-time guide repositioning; 3. having high repositioning precision, carrying out comparison on pixels directly when images are matched, thus being very sensitive to slight change of images, being capable of finding the difference of one pixel in the fine search process, especially fine searching during repositioning, searching a point with smallest error in the current pixel point and 8 neighborhood points thereof all the time.

Description

technical field [0001] The invention belongs to the field of computer applications, and relates to a computer-aided referee system, more specifically, to a method for resetting billiards based on image matching technology in the computer-aided billiard referee system. Background technique [0002] Snooker (Snooker) billiards and American billiards are a sport that is widely welcomed by people, and various competitions are often held at home and abroad. Referees use the method of visual refereeing. However, snooker and American billiards games take a long time, often cause misjudgments due to visual fatigue, some small mistakes are not noticed, and situations that need to be reset, thus often causing some unnecessary For this reason, it is necessary to develop a computer-aided referee system to help referees avoid the above-mentioned situations. This system uses camera viewfinder technology, uses billiard ball positioning technology to track the trajectory of the ball, and as...

[0002] Snooker (Snooker) billiards and American billiards are a sport that is widely welcomed by people, and various competitions are often held at home and abroad. Referees use the method of visual refereeing. However, snooker and American billiards games take a long time, often cause misjudgments due to visual fatigue, some small mistakes are not noticed, and situations that need to be reset, thus often causing some unnecessary For this reason, it is necessary to develop a computer-aided referee system to help referees avoid the above-mentioned situations. This system uses camera viewfinder technology, uses billiard ball positioning technology to track the trajectory of the ball, and assists referees to make correct decisions according to referee rules. Referees, in the process of refereeing billiards, often encounter the situation that the position of the billiard ball on the last stroke is reset to the position of the previous one. How to use the memory function of the computer in the computer-aided referee system to assist the referee to reset the ball accurately is the key The problem to be solved by the invention
