Abstract:

For the problem of the multiview registration of laser imaging data, the coarsetofine strategy is adopted so that a novel coarse registration method is proposed. The proposed method first estimates the rotation excursion angles of variousview point clouds, and then eliminates the existed excursion by corresponding rotation, thus realizing the coarse registration. Finally, ICP (Iterative Closest Point) is employed for fine registration. Experimental results show that the proposed method can realize coarse registration of variousview laser imaging data effectively and demonstrate that the method is simple and highefficient so as to be suitable to differentresolution data.
