Patent ID: 6999072

Claim:
A data processing method of handing a plurality of two-dimensional data to be the base for generating three-dimensional shape data for reproducing a solid object, the method comprising the steps of: (a) the first obtaining step of successively photographing the solid object along a first path around the solid object so as to obtain a plurality of first images; (b) the step of relating the plural first images to each other in a first three-dimensional coordinate system; (c) the second obtaining step of successively photographing the solid object along a second path around the solid object so as to obtain a plurality of second images; (d) the step of relating the plural second images to each other in a second three-dimensional coordinate system; (e) the first specifying step of specifying a plurality of first corresponding points corresponding to a plurality of points appearing on the solid object on a partial first image extracted from the plural first images; (f) the second specifying step of specifying a plurality of second corresponding points corresponding to the plural points on a partial second image extracted from the plural second images; and (g) the step of obtaining relative information about the first three-dimensional coordinate system and the second three-dimensional coordinate system based on the plural first corresponding points specified on the partial first image and the plural second corresponding points specified on the partial second image.
