The planarity constraints: definition, interest and applications

The authors define the planarity constraints, and point out a 3D reconstruction method for polyhedric objects (planar faces). They explain their interest, and then propose a new global/local implementation. This implementation is detailed in the context of an edge-region cooperative segmentation. Conceptually, the advantages of this method are its simplicity, a precise knowledge of its uncertainties and, at the operational level its rapidity and the preciseness of the obtained volumetric reconstruction
