Abstract
Nowadays automatic 3D acquisition systems allow building accurate models of real 3D objects in a cost- and time-effective manner. This technology was used in a particular application context: shape defects detection. Specific needs of this domain are: medium-high accuracy, reliability, and a short acquisition time. A low-cost 3D reconstruction and testing prototype system was designed, based on structured light which compares the reconstructed shape of the tested objects with the reconstructed shape of a reference object. The scanner architecture and the first results obtained by implementing a prototype used to mark local defects of tested objects are presented.
