PURPOSE:To check the validity of arrangement of parts as a judgement object in a picture and check the alignment of parts also in case of plural ojbects by providing a means, which calculates the centroid of a shape as a judgement object, and a means which calculates the direction. CONSTITUTION:A conventional shape judging device is provided with a centroid calculating circuit 311 and a direction calculating circuit 312 additionally. The circuit 311 calculates the centroid of each independent shape separated by the connectivity processing in a connectivity processing circuit 103. The direction calculating circuit 312 calculates the rotation direction of the shape. In case of check, the two-dimensional shape of parts 100 to be checked with a base is picked up by a two-dimensional image pickup device 101, and arrangement feature absolute values and arrangement feature relative values obtained through an A/D converter 102 and circuits 311 and 312 are evaluated. As the result, the correct arrangement of parts on the base is judged even if parts are placed and rotated freely on the base picture. Further, the validity of the arrangement of parts as the judgment object in the picture is checked, and the alignment of parts is checked also in case of plural objects. |
