Problems solved by technology

The problem with this method is that the relative position between the camera and the Go board needs to be kept unchanged, and two frames of images need to be continuously collected to obtain the difference image, and the final image cannot be directly taken to recognize the game record

Embodiment 1

[0028] The technical solution adopted by the present invention to solve the above problems is:

[0029] A kind of go recognition method based on go image, it is characterized in that: comprise the following steps:

[0030] 1) Step 1, use a mobile phone to take pictures of the Go board and the chess pieces on it and carry out image acquisition, and obtain the digital color image of the Go board that is basically square;

[0031] 2) step 2, identify the digital image that above-mentioned steps gathers, search the checkerboard line intersection of all cross features and the checkerboard line intersection of T-character feature on the checkerboard image, concrete process is as follows:

[0032] Scan all the pixels on the checkerboard image (in order to simplify the calculation, you can choose the R, G, B value or its average value to represent the brightness), first exclude the points with higher brightness, and then detect the upper right, lower right, upper left and There are p...

Abstract

The invention relates to a go identification method based on a go image and a go board. The go identification method based on the go image comprises the following steps that cross-shaped and T-shaped feature points are identified by searching the go board image; the four edge lines of the go are found according to the T-shaped feature points; then the positions of the four angular points of the go board are obtained; 17 ideal transverse and vertical go board lines and 361 go board line cross points are calculated through the positions of the four angular points of the go board; the cross-shaped feature points are found near the ideal go board lines and corrected; and go pieces are identified at the positions of the 361 go board line cross points so that go manual data are obtained and the outcome is calculated. The go identification method based on the go image is effective in processing method and high in reliability and can be adaptive to the conditions of a certain degree of distortion and non-uniform illumination so that identification accuracy can be enhanced.

Description

technical field [0001] The invention relates to a go recognition method based on a go image, and a go board which can easily realize the recognition of the go by taking pictures. Background technique [0002] Go is a strategic board game for two players. It was called "Yi" in ancient China and "Go" in the West. Popular in East Asian countries (China, Japan, Korea, etc.), it is one of the four arts of piano, chess, calligraphy and painting. Go originated in China, and it was said that it was created by Yao, and it was recorded in the Spring and Autumn and Warring States Periods. During the Sui and Tang Dynasties, it was introduced to Japan via Korea, and spread to European and American countries. Some scholars believe that Go contains rich connotations of Han culture and is the embodiment of Chinese culture and civilization. Go uses a square lattice board and black and white two-color circular chess pieces to play games. There are 19 vertical and horizontal lines on the ch...
