Abstract:

A method and system for building virtual reality object models. The method includes defining an object space, generating multiple two-dimensional real images of the object, and selecting multiple reference points in each image, the reference points defining an image region, the region having a texture. The method also includes determining the three-dimensional position in the object space of each of the reference points in each image, the positions determined defining a model surface, mapping the texture of an image region onto a model surface, and generating a three-dimensional model of the object using the determined positions and the mapped texture. The system includes one or more cameras, a calibration apparatus, a graphic interface and software for performing the method.
