Airborne LiDAR Point Cloud Strip Adjustment Method

WANG Liying1 SONG Weidong1(1 School of Geomatics,Liaoning Technical University,47 Zhonghua Road,Fuxin 123000,China)  
Considering strip adjustment as key technology to eliminate systematic errors,we propose a method of 3D surface matching without control points.Using the least Z-difference(LZD) and least normal distance(LND)matching algorithm to realize.The experimental results show that the accuracy of LND and LZD algorithm can both meet the requirements of project accuracy;LZD's total efficiency is lower than LND's,but its accuracy is higher.Compared to commercial software TMatch,LZD and TMatch accuracy are at the seme level,and our algorithm can successfully complete the task of strip adjustment when TMatch software failure.
