1. A method for reproducing a shape and a pattern in a three-dimensional scene forming a three-dimensional model used for computer graphics based on a plurality of images, comprising:
- capturing the plurality of images, storing the captured images, selecting a plurality of frames to which processing is applied from the stored images, and extracting correspondence between the plurality of images;
inputting the three-dimensional model to be a base, storing the input three-dimensional model, selecting the three-dimensional model that defines geometric properties of a target object in the images, and specifying correspondence between the images and the three-dimensional model;
deforming the three-dimensional model while satisfying both the obtained correspondence between the images and the obtained correspondence between the images and the three-dimensional model;
generating a pattern image to be attached to a surface of the three-dimensional model, based on a shape of the final three-dimensional model obtained by the deforming, and the specified correspondence between the final three-dimensional model and the images; and
outputting the completed final three-dimensional model.

Abstract
A method and apparatus for reproducing a shape and a pattern in a three-dimensional scene with good precision, based on a plurality of images, by realizing processing that considers a three-dimensional model from the beginning of the processing. A plurality of images are captured, a plurality of frames to which processing is applied are selected from the captured images, correspondence between a plurality of images are extracted, a three-dimensional model to be a base is input, a three-dimensional model that defines geometric properties in a target object in the images is selected, correspondence between the images and the three-dimensional model is specified, the three-dimensional model is deformed while satisfying both the correspondence between the images and the correspondence between the images and the three-dimensional model, a pattern image to be attached to a surface is generated based on a shape of the three-dimensional model and the correspondence between the three-dimensional model and the images, and the final three-dimensional model is output.
