Planar feature extraction in laser scaning data using region growing algorithm

XU Wen-xue①,JIANG Tao ①② ,KANG Zhi-zhong ③ (①Geomatics College,ShanDong University of Science and Technology,ShanDong Qingdao 266510,China; ②Laboratory of Fundamental Geographic Information and Digital Technology,Key Laboratory of ShanDong,ShanDong Qingdao 266510,China; ③Faculty of Aerospace Engineering,Delft University of Technology,Kluyverweg 1,2629 HS Delft,The Netherlands)  
Laser Scann has been the focus in the field of 3D-City,and it has favorable outlook in the field of 3D modeling.In this paper,the method could be better applied to the extraction of primary objects of the Laser Scaning data.The author first introduce the phase-shift laser ranging theory of the 3D Laser Scaning,analysis the plane equation of the 3D Laser Scaning data,combine with region growing algorithm carry on the segment to the Laser Scaning Data,ang then can extraction the plane feature.Finally,the author carry on the experiment and the analysis to this method.
