Orientierung Von Laserscanner-punktwolken

The orientation of laser scanner point clouds is one of the fundamental steps in the process of creating three-dimensional digital representations of existing objects. Orientation is the task of finding the correct positions of two or more point clouds (that only partially represent the object) obtained from different viewing positions, such that the full object in consideration is correctly described. In communities outside of Photogrammetry and Remote Sensing, instead of ‘orientation’ the terms ‘registration’ or ‘matching’ are used to describe the same task. This article is an exposition of a talk given by the first author at the continuing education ‘Laserscanning’ of the Institute of Photogrammetry and Remote Sensing of the Vienna University of Technology on September 24th, 2003. The article gives an overview of fundamental orientation methods for laser scanner point clouds.
