Unformatted text preview: D inspection systems has been approached to determine optimal inspection strategies [Huang & Gu, 1998], driving the scanning system for freeform surfaces and related data verification. The points cloud data analysis to perform the geometrical tolerance verification is a consolidated functionality of the most common reverse engineering commercial software systems (RapidForm by Inus Tech., Geomagic Qualify by Raindrop, Polyworks by Innovmetric), but they provide only algorithms to facilitate the feature extraction within a dense points cloud data. In fact, they are completely disjointed from the tolerance specification process and, furthermore, they require constant user interactive decisions for the inspection task and for data segmentation. An advanced and integrated solution proposed in literature [Prieto et al., 2000] is the most effective example of inspection automation, but the CAD model is used only as reference to perform the range data segmentation activity. A robust method to partition the points cloud data [Benko & Varady, 2004] is one of the main problems to be consider...
