3-dimensional figure of the curved surface reconstruction device and three-dimensional shapes of curved surface reconstruction program

摘要

PROBLEM TO BE SOLVED: To provide a curved surface reconstruction method for a three-dimensional graphic and a program therefor which can complement the defective part of a graphic from ambient data.;SOLUTION: This curved surface reconfiguration method comprises: an input process for inputting data obtained by discretely sampling a distance place with sign with normal information, which is configured of a distance with sign from a predetermined sample point 11 to an object surface 10 expressed with a vector p and a normal to a nearest point 12 in a three-dimensional space; and an approximation process for carrying out the local secondary approximation of the distance place with sign with normal information expressed with the components of a predetermined normal vector n, distance s with sign and symmetric matrix M to a normal vector n_i in the neighborhood of the i-th sample point deviated only by a vector Δp_i from the sample point 10 expressed with the vector p and a sample value s_i of the distance with sign.;COPYRIGHT: (C)2006,JPO&NCIPI
