Abstract:
Many tasks in airborne laserscanning require the registration of differentscans of the same object. Especially data acquired in urban environments with buildings viewed obliquely from different directionsneed to be aligned. In this paper we propose a method tofilter these point clouds based on different techniques to speed upthe computations and achieve better results with the ICP algorithm. A statistical analysis is used and planes are fitted tothe data wherever possible. In addition to this, w...     »
