PROBLEM TO BE SOLVED: To provide a free viewpoint image generation method, device and program capable of reproducing the texture of an occlusion area for some or all multi-viewpoint images.SOLUTION: A first planar projective transformation matrix Hbetween image coordinates photographed at the time t0 by a camera c1 and image coordinates photographed at the time t0 by a camera c0 is calculated, a second planar projective transformation matrix Hbetween image coordinates photographed at the time t1 by the camera c1 and image coordinates photographed at the time t0 by the camera c1 is calculated, the first matrix Hand the second matrix Hare multiplied, and a third planar projective transformation matrix between the image coordinates photographed at the time t1 by the camera c1 and the image coordinates photographed at the time t0 by the camera c0 is calculated. By using the third planar projective image transformation matrix, from a first reference image for which a subject is photographed at the time t1 by the camera c1, the pertinent area of a 0-th image that can be photographed at the time t0 by the camera c0 defined as a virtual viewpoint is generated. |
