ZHANG Yan-ting①,MA Dong-Yang②③,MA Hao①,GUAN Yan-ling②(①College of Geodesy and Geomatics,Shandong University of Science and Technology,Shandong Qingdao 266510,China;②Chinese Academy of Surveying and Mapping;Beijing 100039,China;③Institute of Surveying and Mapping,Information Engineering University,Zhengzhou 4500052,China)  
This paper first analyzed the influence factors of angle measurement error of laser scanner,and mainly studied and discussed two calibration methods of angle measurement error of 360 ° vehicle-based laser scanner,one is dynamic method and the other is static one;then,the paper processed the point cloud data with TerraScan software and matlab and conducted a detailed analysis of the testing results;finally,it concluded that the laser scanner calibration techniques and methods would become more mature and perfect in the future.
