Abstract:Reliable identification of the discontinuities from range data is an important problem in many application domains, such as reverse engineering, object recognition, industrial inspection, and autonomous navigation. In this paper, a novel method is proposed for identifying the C0, C 1, and C2 discontinuities from range data based on similarity indicators. We research the behaviors of the principal curvatures at the discontinuities and define the similarity indicator at a point. Based on the similarity indicators, the C0, C1, and C2 points are identified from range data. The similarity indicators make the threshold setting easier and more reasonable, and improve the performance of discontinuity identification. The experimental results demonstrate that the proposed method is efficient and reliable. © 2011 IFAC.
