<P>PROBLEM TO BE SOLVED: To provide a free-viewpoint image generating method or the like capable of generating an image of an optional viewpoint by detecting a parallax vector by block matching and using the parallax vector even when the surface of an object is inclined with respect to optical axes of a plurality of camera. <P>SOLUTION: One and the same rotational transformation is applied so as to make the optical axes of the two cameras perpendicular to the same plane going through the cameras. Depth distance Z of an optional point and a unit normal vector at an optional point of the surface of an object are determined arbitrarily, moved by a parallax vector based on t and Z, transformed by a primary transformation matrix based on t, Z and n and matched to a block of a second image. While changing Z and n arbitrarily, a second block of the second image that resembles a first block of a first image most is retrieved. A block of an image from an optional viewpoint is generated in accordance with an internal division ratio of an optional viewpoint on a straight line connecting the two cameras. <P>COPYRIGHT: (C)2008,JPO&INPIT |
