Abstract
A position recognition method wherein the photographic image of an object having a concavity or convexity defined therein is converted into specified feature space data; detection is performed to determine whether the specified feature space data possessed by each elementary area of the converted image has a symmetric relation with one possessed by another elementary area with a virtual center of the concavity or convexity being the center of symmetry; and the position of the concavity or convexity of the object is recognized based on the detection.
