Abstract

PURPOSE: To realize a general-purpose and quick parts discriminating method, by extracting the data based on the video information of the parts to decide the dictionary pattern and then giving a comparison between the dictionary pattern and the real reference point obtained from the parts video information.
CONSTITUTION: The image pickup device 9 divides the image into the minute picture elements in a finite number, gives an electrical conversion to each picture element and furthermore binary-codes each picture element. The discriminating device 10 consists of the dictionary pattern producing part 13 and the pattern comparing part 14 and then gives an overlap of the video information 15 in terms of several positions of the parts to form the closed partial region 16 with the boundary line of each position. The reference point is formed through the region 16 and then stored in the memory within the dictionary pattern producing part in the form of a dictionary pattern received a choice and selection. Then a comparison is given through the comparing part 14 between the dictionary pattern and the actual video information, thus giving a discrimination for both the shape and the position of the parts.
