Embodiment

[0110] The concrete program execution of this method is:

[0111] A. Background modeling

[0112] A1. In order to average the noise, the present invention collects 20 frames of background images of the nine-ball table, and performs color Gaussian modeling on the background images: read the color data of each frame of the background image, red R, green G, blue B.

[0113] A2. Calculate the hue H of the corresponding HIS color model space according to the RGB value of each pixel

[0114] θ = cos - 1 ( ( R - G ) + ( R - B ) 2 ( ...

Abstract

The invention discloses a nine-ball computer-assisted detection identification method and belongs to the field of digital image processing. The method aims to solve a technical problem of performing real-time multi-target positioning and identification on a table according to video data. The method includes the following steps: using background color gaussian probability modeling to perform rough target detection so as to filter part of interferences; then based on edge detection, performing edge detection of three algorithms on filtered targets, wherein each algorithm relates to two layers of thresholds; using an edge detection result to perform Hough-conversion for circle center detection and determining sequentially the sphere center of each target; and finally, using a color European distance to calculate the difference of detected targets and color centers so as to obtain the color of each target and achieve identification of the targets. The nine-ball computer-assisted detection identification method is capable of performing real-time multi-target identification and positioning in a nine-ball environment so that ball position error judgments of a judger under a complex condition are reduced and the accuracy and fairness of nine-ball positioning judgments are improved.

Description

technical field [0001] The invention relates to digital image processing, more specifically to a multi-target detection and recognition method applied to nine-ball sports. Background technique [0002] As an indoor leisure sport, billiards is deeply loved and concerned by people; at the same time, this sport is also a competition event in many international professional competitions, showing more and more sports charm and influence. During the game broadcast, in order to simulate the real scene, it is often necessary to detect and identify the billiard ball situation on the ball hit by the player. At present, the "Chinese Eagle Eye" snooker auxiliary broadcast system has been realized and used. This system has a good effect on the application of snooker games. But billiards not only has snooker billiards, but also nine balls. The situation of snooker billiards is different from that of nine balls. In snooker, there are pure color balls, and nine balls are colored balls. T...
