PROBLEM TO BE SOLVED: To recognize an article of an arbitrary shape at a high speed by deciding a straight line as a separation line and separating adjacent articles by the sparation line if an area surrounded by contour line is an integral multiple of area of a preliminary fixed article as geometrical feature quantities of an article. SOLUTION: An arithmetic part extracts the contour line of an image of a bolt 1 and determines a point A of inflection in which this contour line rapidly bends at an external angle θA. Further, the arithmetic part determines S1 , S2 surrounded by the contour line on both the sides of a straight line connecting two points A1 , A2 of inflection on the contour line of the bolt. If the area S1 , S2 is an integral multiple of areas S of the bolt which is preliminarily fixed as the geometrical feature quantities of the bolt, the straight lines A1 , A2 are decided as separation lines K. Thus, the arithmetic part separates adjacent bolts by the separation lines K and separately recognizes the bolts. |
