<P>PROBLEM TO BE SOLVED: To provide an image processing apparatus, an image processing method and a program which are capable of estimating a position/attitude of a specific area in an image with high accuracy. <P>SOLUTION: The image processing apparatus includes: a feature point extraction part 11 for extracting a feature point of an input image I1; a matching part 12 for determining correspondence of the feature point with a reference image R; a homography calculation part 13 for calculating a relation of projection between the input image I1 and the reference image R based on the correspondence; and an image conversion part 14 for converting at least a part of the input image I1 based on the relation of projection. The homography calculation part 13 calculates a homography matrix H1 based on the correspondence of the feature point with the reference image R for the input image I1, and calculates a homography matrix H2 based on the correspondence of the feature point with the reference image R for the input image I1 converted by the image conversion part 14 on the basis of the homography matrix H1, and calculates again the relation of projection between the input image I1 and the reference image R based on the homography matrixes H1, H2. <P>COPYRIGHT: (C)2012,JPO&INPIT |
