Embodiment Construction

[0057] The specific embodiments provided by the present invention will be described in detail below in conjunction with the accompanying drawings.

[0058] Such as figure 1 As shown, a method for automatic notation of Go based on video recognition technology, including the following overall steps:

[0059] Step 1. Initialization. First, obtain an original image including the entire blank chessboard and additional four-corner positioning marks through the camera as the original frame; the difference between the initialization frame and the previous frame is 0, and the reference frame is the original frame;

[0060] Step 2, chessboard positioning, adopting the four-corner positioning method of the back-shaped positioning mark, carrying out chessboard positioning to the original frame, obtaining the specific position coordinates of 361 points of the Go chessboard in the image;

[0061] Step 3, frame calculation, take out the video captured by the camera at a rate of 10 frames pe...

Abstract

The invention provides an automatic Go notation method based on a video recognition technology. The method comprises the steps that 1) according to initializing, a camera is used to acquire a raw image including the entire blank chessboard and an additional four-corner positioning mark as an original frame; 2) according to chessboard positioning, the four-corner positioning method of the rectangular-ambulatory-plane positioning mark is used to carry out chessboard positioning on the original frame to acquire the specific position coordinates of 361 points of the Go chessboard in the image; 3) according to frame taking calculation, videos acquired by the camera are taken out at the speed of 10 frames per second and undergo image processing one by one, and a matrix frame difference determining method is used to determine the drop point change status of the chessboard; and 4) a chess manual file is generated. The method can effectively remove irrelevant image interference around the chessboard, and greatly simplifies the image processing capacity. The matrix frame difference determining method is used, so that the image after four-corner positioning and cutting can determine the drop point status of the chessboard by determining the frame difference of the entire image.

Description

technical field [0001] The invention relates to the technical field of automatic notation methods for Go, in particular to an automatic notation method for Go based on video recognition technology. Background technique [0002] Go, originated in China, is a strategic chess game for two players. It was called "Yi" in ancient China and "Go" in the West. It can be said to be the originator of chess. It has a history of more than 4,000 years. Go, popular in East Asian countries (China, Japan, Korea, and North Korea), is one of the four arts of piano, chess, calligraphy and painting. It is said that it was written by Emperor Yao, and it was recorded in the Spring and Autumn Period and the Warring States Period. During the Sui and Tang Dynasties, it was introduced to Japan via Korea, and spread to European and American countries. Go contains rich connotations of Chinese culture and is the embodiment of Chinese culture and civilization. [0003] Go uses a square lattice board an...
