Texture mapping method
First Claim
Patent Images
1. A texture mapping method comprising the steps of:
- inputting data of an original picture obtained by photographing a scene and data of a texture picture to be mapped on the original picture;
estimating three-dimensional coordinates x,y,z which express a surface shape of a predetermined part in the original picture on the basis of the data of the original picture in accordance with an operator'"'"'s instruction data;
modifying the estimated surface shape three-dimensionally in a three-dimensional space by designating a three-dimensional vector modification of a three-dimensional coordinate point on the estimated surface shape;
mapping the data of the texture picture onto the estimated surface shape; and
outputting picture data obtained in the mapping step, whereby the operator can visually evaluate the estimated surface shape.

Abstract
A texture mapping method projects a specified texture picture onto the surface of an object in another specified picture. Three-dimensional data on the surface shape of the object to be projected is not known previously. The three-dimensional data on the surface shape of the object is estimated on the basis of the data in the objective picture to attain the texture mapping.
