| Abstract: | Laser rangefinder and CCD camera have the excellent ability of capturing information of object in environment respectively,and used for 3D modeling widely.In this paper,we integrate the high speed capturing of laser rangefinder with the fast processing of CCD image to research the 3D modeling method by introducing the algorithm of extrinsic calibration.The improved extrinsic calibration method was proposed,and then a novel method for point cloud segmentation was presented,and finally the 3D reconstruction a... |
