COOPERATION OF 3D SEGMENTS A N D 3D FACETS INFORMATION FOR OBJECT RECONSTRUCTION

International audienceGiven a serie of trinocular images of an object, we have developed a method for building 3D facets and 3D segments model of the object. Frorn each triplet, a partial description of the object, called 3D View, is extracted. From the set of all extracted 3D Facets, a strategy for guiding the object reconstruction, based on a statistical method is developed. A 3D Matching Builder computes matchings between 3D Primitives of consecutive 3D views. Guided by the Strategy, a Superstructure gathered all the matching informations given by the 3D Matching Builder in a set of equivalence classes. For each equivalence class, of Superstructure, a representative is derived. The 3D Primitives model is finally computed merging informations of 3D Facets representatives and 3D Segment representatives. This method implemented in Smalltalk80 has been applied on a series of stereoscopic real images triplets; some results are provided at the end of the paper
