specific Embodiment 1

[0043] Specific embodiment 1: a kind of Go automatic notation method based on video recognition technology, comprises following general steps:

[0044] 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;

[0045] 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;

[0046] Step 3, frame calculation, take out the video captured by the camera at a rate of 10 frames per second, and perform image processing one by one, and use the matrix method to judge the frame difference to judge the change state of the checkerboard point...

Abstract

The invention provides a chessboard positioning method for automatically recording a go chess manual based on video recognition. The chessboard positioning method is included in a go chess manual recording method based on image recognition. The chessboard positioning method uses positioning marks, which are icons in rectangular ring shapes at four corners, as positioning identifiers, and calculates the specific coordinates of 361 points in the chessboard according to the locations of the four corners of the chessboard and the horizontal and vertical spacing standard of the chessboard. The method is characterized by arranging icons in rectangular ring shapes on the four corners of the chessboard as image recognition control points for positioning the chessboard, calculating the specific coordinates of 361 points in the chessboard according to the positions of the four corners of the chessboard, eliminating irrelevant image interference around the chessboard, and greatly decreasing image processing amount.
