【摘要】 研究了手持式三维扫描仪的自定位算法,并提出了改进算法以弥补ICP算法和穷举法等经典定位算法的局限性。通过实验对比Delaunay四面体法、ICP算法、最小三角形法和频率三角形法的重构效率,实验结果表明频率三角形法更高效更稳定,在各种环境下均具有可行性。更多还原

【Abstract】 Self-referencing algorithms of the handheld 3 d scanner was mainly dissussed.Finst the classical algorithms is introduced,including the iterative closest point(ICP) algorithm and the exhaustive distance algorithm,and it also introduces the defects that exist in these algorithms.Then three triangulation algorithms are introduced.Throagh experiment,the three triangulation algorithms is compared with the reference exhaustive-distance algorithm,and analysied the advantages and disadvantages of these algorithms.The resalts are used to determine the best of the three.更多还原
