The present invention is intended to reconstruct or acquire the shape of an object without rotating it. A TV camera 15 with a fish-eye lens 16 is used to conduct the image-sensing of a vehicle 12 as a moving object over a certain section of its path of travel and a background image is subtracted from each captured image to obtain a silhouette of the vehicle. The loci of movement of vehicle's tires in each image are calculated and used to calculate the positions of the viewpoint of the TV camera and the vehicle relative to each other in each image. The shape of the vehicle is reconstructed by projecting the silhouette for each captured image into a projection space while holding the viewpoint of the TV camera and the vehicle at the calculated relative positions. |
