WebThis paper discusses how local measurements of three- dimensional positions and surface normals ( recorded by a set of tactile sensors, or by three-dimensional range sensors ), may be used to identify and locate objects from among a set of known objects. WebAnalysis of scenes of three-dimensional objects has, in the past, been largely limited to the world of polyhedra. Techniques for generating structured, symbolic descriptions of complex curved objects by segmenting them into simpler sub-parts are ...
