Abstract

PURPOSE:To identify the directivity even with an object having symmetrical property by defining the centroid of the object as a reference point and at the same time deciding a peculiar point viewed from the reference point as a deciding point for identification. CONSTITUTION:The image of master parts is picked up by an image camera 41 and at the same time a signal Sy is binarized 31. The binarized signal Sb is written in a frame memory 32. While the signal Sb is read out by a CRT controller 37 and a master pattern is displayed on a display 42. A controller 37 sets the centroid and reference line of the master pattern. Then a cursor is shifted on a display screen and a deciding point is set. The deciding result (black/white information) of the deciding point is registered in a RAM 13 as master data. The centroid and reference axis of the pattern of an object parts are obtained. The black/white information on the cursor position is taken out and compared with the black/white information of the master pattern. Based on this comparison information, the directivity of the subject pattern is outputted.
