Abstract
Plural range images having different resolutions are generated from an input range image and normal vectors are calculated for each generated range image. An edge map is formed for each of the plural range images based on the calculated normal vectors and a single edge map is formed by synthesizing the plural formed edge maps. Polygon data describing the surface shape of an object represented by the input range image are formed based on the synthesized edge map. Polygon data of high precision that represents characteristics of the surface shape of the object is thereby formed with little data.
