Abstract
Driven by progress in sensor technology, algorithms and data processing capabilities, terrestrial laser sensor has found a wide range of new application fields over the past two decades. Terrestrial laser sensor directly delivers 3D points through an array of coordinates (point cloud) and provides a three-dimensional sampled representation of the surfaces of terrestrial objects. The fully automatic registration of terrestrial laser scanning point-clouds is still a question as it involves handling huge datasets, irregular point distribution, multiple views, and relatively low textured surfaces. In this paper, we propose a key point based method using reflectance intensity and geometry features for the automatic marker-free registration of terrestrial laser scans. We apply the SIFT method for extracting feature points from the reflectance intensity image and geometric constraint for excluding false matches. To evaluate the performance of proposed method, we employ a test scene "Holzmarkt" in downtown Hannover, Germany. Reference orientations are acquired by the standard orientation procedure using retro-reflective targets and manually assisted target selection. In the experiments, we present the results of the proposed method regarding performance, accuracy and running time for the test scene.
