Abstract
A feature point generation system capable of generating a feature point that satisfies a preferred condition from a three-dimensional shape model is provided. Image group generation meansgenerates a plurality of images obtained by varying conditions with respect to the three-dimensional shape model. Evaluation meanscalculates a first evaluation value that decreases steadily as a feature point group is distributed more uniformly on the three-dimensional shape model and a second evaluation value that decreases steadily as extraction of a feature point in an image corresponding to a feature point on the three-dimensional shape model becomes easier, and calculates an evaluation value relating to a designated feature point group as a weighted sum of the respective evaluation values. Feature point arrangement meansarranges the feature point group on the three-dimensional shape model so that the evaluation value calculated by the evaluation meansis minimized.
