CAD based planning and execution of inspection

The authors have created an interface between computer vision processes and CAD (computer-aided design) databases as part of the development of an automated visual inspection system. A recognition planning system uses rules to select the important vision features from the given CAD database and generates feature-recognition procedures. An inspection planning system provides overall inspection procedures given the CAD database. This system provides such information as a list of features to be measured, techniques to use, and the range of values allowed. Thus, after the design cycle, parts can be thoroughly inspected with no technical decisions or programming required
