METHOD, APPARATUS FOR SHAPE ESTIMATION, AND NON-TRANSITORY COMPUTER-READABLE STORAGE MEDIUM
First Claim
1. A method for shape estimation, performed by a computer, the method comprising:
- executing, by a processor of the computer, extraction processing that includes extracting a plurality of feature points from a plurality of pieces of image information of a same subject photographed with a time difference;
executing, by a processor of the computer, estimation processing that includesfirst processing for selecting feature points from the plurality of feature points;
second processing for estimating a three-dimensional shape of the subject based on the selected feature points;
third processing for removing the feature points from the plurality of feature points after the estimation of the three-dimensional shape based on the feature points; and
fourth processing for executing the first processing, the second processing, and the third processing on the plurality of feature points from which the feature points are removed by the third processing; and
executing, by a processor of the computer, integration processing that includes integrating a plurality of the three-dimensional shapes estimated by the estimating processing.
