Abstract:
1. An object recognition apparatus comprising: a processer to implement a typical feature point extracting unit that extracts a plurality of typical feature points from a typical image; a first feature calculating unit that calculates a feature of each typical feature point from image data of the typical image; an object feature point extracting unit that extracts a plurality of object feature points from an input image; a second feature calculating unit that calculates a feature of each object feature point from image data of the input image; a corresponding point setting unit that calculates similarities between the feature of one typical feature point and the features of the object feature points for each typical feature point, judges based on the similarities whether or not the features of both one typical feature point and one object feature point in each pair are similar to each other, and sets one typical feature point and one object feature point in each pair, having the features similar to each other, as a typical corresponding point and an object corresponding point matching with each other; an information producing unit that produces position information indicating positions of the typical feature points in the typical image; a judging unit that judges based on position information of the typical corresponding points whether or not a positional relationship between or among the object corresponding points is substantially similar to a positional relationship between or among the typical corresponding points; and a recognizing unit that recognizes an object picture having the object corresponding points in the input image as an object indicated by the typical image when the judging unit judges that the positional relationships are substantially the same as each other.
