ABSTRACT:
A pose estimation and comparison system has a pose estimation and comparison unit. The pose estimation and comparison unit has an pose candidate decision unit which decides an pose candidate. According to the generated pose candidate, a comparison image generation unit generates a plurality of comparison images close to the input image, while projecting a three-dimensional object model obtained from a three-dimensional object model storage unit to a two-dimensional image. A sharpness extraction unit extracts a first sharpness amount reflecting the sharpness from each of the generated comparison images. A weighted difference calculator calculates a plurality of weighted differences by weighting the first sharpness amount to the difference between the input image and each of the comparison images. A determination unit selects a comparison image having the smallest weighted difference as the comparison image closest to the input image, thereby performing the pose estimation and comparison.
