WebJan 19, 2016 · In vision-based measurement, there is a lack of effective methods for local contour matching of flexible automotive rubber product contour due to its flexibility. In this paper, we propose a novel local contour point set matching method based on a geometric descriptor. A geometric descriptor of a local point set includes shape properties of the … In computer vision, pattern recognition, and robotics, point-set registration, also known as point-cloud registration or scan matching, is the process of finding a spatial transformation (e.g., scaling, rotation and translation) that aligns two point clouds. The purpose of finding such a transformation includes … See more The problem may be summarized as follows: Let $${\displaystyle \lbrace {\mathcal {M}},{\mathcal {S}}\rbrace }$$ be two finite size point sets in a finite-dimensional real vector space See more When the correspondences (i.e., $${\displaystyle s_{m}\leftrightarrow m}$$) are given before the optimization, for example, using feature matching techniques, then the optimization only needs to estimate the transformation. This type of registration … See more • Point feature matching • Point-set triangulation • Normal distributions transform See more • Reference implementation of thin plate spline robust point matching • Reference implementation of kernel correlation point set registration • Reference implementation of coherent point drift See more Correspondence-based methods assume the putative correspondences $${\displaystyle m\leftrightarrow s_{m}}$$ are given for every … See more Iterative closest point The iterative closest point (ICP) algorithm was introduced by Besl and McKay.
