Abstract
Feature lines are substantial means for the segmentation of measured point clouds, especially if a surface model has to be generated from the data. In this article, methods for the automated extraction of feature lines from measured or scanned point clouds will be described. These methods can be applied to points from anay sensor since they do not require sorted or edited data sets. The mathematical basis for the feature line extraction, experimental results and the limits of the methods will be presented.
