Abstract

The invention discloses a billiard ball positioning method which comprises the following steps: acquiring attribute information of a billiard table top, manufacturing positioning substrates with different colors according to the attribute information, and flatly laying the positioning substrates on the billiard table top; shooting the billiard table surface on which the positioning substrate is laid to obtain a reference image; acquiring a local image including a target billiard ball, and determining first positioning information of the target billiard ball in the local image; taking an image where the target billiard ball is located in the local image as a first foreground image, and performing removal processing to obtain a first background image; matching the first background image with the reference image, and determining second positioning information of the first background image on the reference image according to a matching result; and determining position information of a target billiard ball according to the first positioning information and the second positioning information. Accurate positioning of billiards is realized.

Description

technical field [0001] The invention relates to the technical field of billiards, in particular to a method for positioning billiards. Background technique [0002] Billiards is an elegant indoor sport that is widely popular in the world. It is an indoor entertainment sport that uses a cue to hit a ball on the table, and relies on completing goals or calculating scores to determine the outcome of the game. During billiards training or a billiards game, it is necessary to accurately obtain the position information of the billiards, so as to obtain hitting training parameters or judge the score according to the position of the billiards. In the prior art, the position information of the billiard ball cannot be accurately obtained, which affects the user experience. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the above-mentioned technologies at least to a certain extent. Therefore, the purpose of the present invent...
