Abstract
The success of CIM relies on automatic interfaces between CAD/CAM systems and sensor/robot technologies. Automatic reconstruction of objects in CAD systems based on processing scanned information is vital to inspection and recognition operations in a flexible manufacturing cell containing CAD/CAM, sensor and robot systems. The development of an automated modelling system that depends on digitized geometric (range) data of an object is presented. Such a system can provide a unified means of linking a CAD system with sensors and robots. A review of computational geometry provides the rationale for processing the range data obtained from a 3D laser digitizer. The fundamental processing steps for edge and surface detection for modelling are described. Tasks for recognizing and classifying 3D edge and surface features leading to region classification of a model are briefly explained. © 1990 CIRP.
