PROBLEM TO BE SOLVED: To generate three-dimensional model data completely representing the three-dimensional shape of an object by using stereoscopy and to generate a moving picture of the object viewed from an arbitrary viewpoint. SOLUTION: The object 10 is photographed by multi-lens stereoscopic cameras 11, 12, and 13 arranged at difference places to obtain luminance images of the object 10 and distance images showing the distances to the external surface of the object 10 by the cameras 11, 12, and 13. According to the luminance images and distances, voxels present on the external surface of the object 10 are determined among many voxels 30 obtained by virtually subdividing the space 20 including the object 10 and the luminance of the object 10 in each voxel is determined. According to the results, a three-dimensional model for the object 10 is generated and used to render an image obtained by viewing the object 10 from an arbitrary viewpoint 40 by using the three-dimensional model. As a modification, the generation of the three-dimensional model for the object 10 is omitted and an image obtained by viewing the object 10 from the arbitrary viewpoint 40 can be generated directly on the basis of the luminance images and distance images. |
