CURVE APPROXIMATION METHOD, CURVE APPROXIMATION APPARATUS, AND CURVE APPROXIMATION PROGRAM

摘要

A method for approximating a shape represented by a sequence of point as a curve, comprising a step for selecting arbitrary points included in a sequence of a plurality of point as points being processed (S102), a step for further selecting at least one point included in the sequence of points as a reference point (S103), and a step for calculating interpolation points required for curve approximation of the sequence of points from the points being processed and the reference points selected at steps S102 and S103 (S104), wherein the processing is executed for all points included in the sequence of points (YES at S1016).
