Abstract

The technique of machine perception of three-dimensional objects implies the generation of a computational model of a solid in a computer. The topic of Computational Geometry deals with the representation, manipulation and generation of geometric data in computational systems. Four principle classes of representational schema are used: point sets, facetted models, functional and procedural. An abstract data type is defined by the values it may take on and by the operations which are defined over those objects. The operator classes associated with three dimensional solids are: solid transformations, visualization, continuation (or interpolation), mensuration and set operationsions. The utility of the various mathematical and computational formulations of computational geometry to the problems of machine perception of three-dimensional objects will be analyzed.
