3D scene reconstruction from multiple intensity images

Methods for constructing face-edge-vertex models of objects directly from image data are presented. Each model bounds the actual positions of surfaces on the object. The techniques rely on topology significant image features to generate bounding volumes for the object surfaces. Potentially occupied volumes obtained from the multiple image viewpoints are intersected to form a cumulative description of potential surface positions. In conjunction with certain coherence and visibility assumptions, a model can be produced with little or no ambiguity. Typically, several well-chosen views will produce a good approximation to the object under consideration. Illustrative examples of building models from multiple intensity images are provided.<
