CHT based automatic go recording system and the method

The present invention automatically Monarch notation reduce the amount of calculation by using a circular Hough transform based on detecting the circular shape of the stones, difference of illumination change or existing stones subtle change in position accurately detect the position of the stones, and the edge in the image of the way giant relates to a system and method, by automatically Monarch notation method according to the invention use portions (a) acquiring image by photographing a grid full, the method comprising: acquiring an image, (b) by parts of the image scale, the obtained step to reduce the image size by reducing the width and height of an image at a predetermined ratio, (c) the step of using parts in black and white image generation, and converts the acquired grid images to grayscale generates a black and white image, (d) the edge detection used in the step of detecting an edge in the converted image grid and (e) using automatic call notation, a circular Hough transformation (CHT-circular Hough transform) Based at detecting the position of the stones, and in that the technical features, including the step of recording the notation.
