Flexible inspection system based on a vision guided coordinate measuring machine.

The objective of this paper is to develop a flexible three-dimensional inspection system for sculptured surfaces by employing 'Coordinate Measuring Machine (CMM), CAD database and vision system technology. New surface identification and rough localization methods are suggested using a concept called 'Z-layers' and a vision guided system. The Z-layers are generated from a CAD database which classifies the three-dimensional models. The three-dimensional models are reconstructed using a vision system that identifies the model and roughly identifies the orientation and location of the object implementing Z-layers. Then inspection planning and fine localization methods are mapped out which are based on the CAD database. The experimental results indicate that the developed inspection system, with the proposed algorithm, can be implemented in modern industry to reduce measurement errors and increase productivity.
