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 present invention provides a kind of Go automatic notation method based on video recognition technology, comprises the following general steps: 1) initialization, earlier obtains a frame to comprise the original image of whole blank chessboard and additional four-corner positioning mark by camera as original frame; 2) Chessboard positioning, using the four-corner positioning method of the back-shaped positioning mark, performing chessboard positioning on the original frame, and obtaining the specific position coordinates of 361 points on the Go chessboard in the image; 3), frame calculation, the video obtained by the camera according to the following The speed of 10 frames per second is taken out, image processing is carried out one by one, and the method of judging the frame difference is adopted to judge the change state of the chessboard points; 4) generate the chess record file. This method can effectively remove the irrelevant image interference around the chessboard, which greatly simplifies the amount of image processing; using the matrix method for judging the frame difference, the image after four-corner positioning and cutting can judge the position of the chessboard by judging the frame difference of the entire picture state.

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.
