Abstract
A plurality of partial shape data that are obtained from widely varying viewpoints (potential directions) are registered. Each of the partial shape data is represented by shape vectors, and corresponding shape vectors representing the plurality of partial shape data are merged through vector arithmetic to thereby obtain shape vectors representing shape data that is obtained by merging the plurality of partial shape data.

A method of merging a plurality of three-dimensional shape data describing shapes of a three-dimensional object taken from a plurality of viewpoints, comprising the steps of:
- (a) performing registration of said plurality of shape data to obtain a plurality of registered shape data;
- (b) representing each of said plurality of registered shape data by respective shape vectors, each of said shape vectors having a range component and a directional component, origin points of said shape vectors being on a surface of said three-dimensional object;
- and
- (c) merging said plurality of registered shape data each represented by said shape vectors, through vector arithmetic.
A method of representing three-dimensional shape data describing a shape of a three-dimensional object, said method comprising the steps of:
- providing shape vectors each having a range component and a directional component, origin points of said shape vectors being on a surface of said three-dimensional object;
- and
- representing said three-dimensional shape data by using said shape vectors.
