Design by quality product digitization

The use of reverse engineering in product design has markedly increased recently. The ability to accurately combine CMM and laser scanning data, and hence realize the potential benefits of both, is impaired by a number of uncertainties inherent to each digitization process. In order to ensure the quality of the digitized data, and accurate representation of the designer's intent, it is a pre-requisite to assess the measurements uncertainties and their sources, and to develop compensation methodologies. This paper discusses an approach for evaluating and compensating errors, primarily due to view registration. Hence the measurements are made as accurate as possible by design.
