Abstract:
A computer software product including a recording medium in which computer-readable software programs are recorded, wherein said software programs are directed to a computer-executable process of composing a plurality of three-dimensional data obtained by measuring an object from a number of viewing points, said three-dimensional data defining a plurality of original meshes representing a plurality of surface images of said object observed from different directions and/or distances, said process comprising the steps of:(a) converting said plurality of original meshes into a first surface mesh through a volumetric method; (b) correcting a mesh structure of said first surface mesh by comparing said first surface mesh with said plurality of original meshes, to thereby obtain a second surface mesh; and (c) correcting a local position of said second surface mesh by comparing said second surface mesh with said plurality of original meshes, to thereby obtain a third surface mesh, wherein said plurality of orignal meshes and said first, second and third meshes are defined by a set of polygons, and a composed result of said plurality of three dimensional data is given by data representing said third surface mesh.
