Abstract

PURPOSE: To recognize the shape of profile from graph automatically in high speed, by arranging in good order for the points of pair registrated through seeking the same points sequentially from other pair by taking one of them as start point and recognizing the shape of graph based on the content registrated in the sequence of connection.
CONSTITUTION: The unit 1 scanning and picking up graph in two dimensions is provided, the video signal obtained every scanning line from this is binarized 14, and the X coordinate at the dark and bright change point of this binary signal and the Y coordinate of the scanning line are obtained and memorized. Further, the coordinate of the dark and bright change point for the specified scanning line memorized and that for the next scanning line are detected 16, and the point coordinate is formed in pair from the ascending order of X coordinate and memorized in the connection reference table 38. Among the memorized pair points, one is taken as the start point. The same point as this point is sought from other pairs sequentially and they are arranged in good order and memorized in the connection sequential table 40, and the shape of graph is recognized based on the content memorized.
