    • Abstract
  • Terrestrial laser scanner(TLS) is a kind of new sensors which has been developed in recent years.In order to construct the objects using the point clouds,one of the problems has to be tackled first is feature extraction.In order to extract linear and circular features of ancient architecture,we segment point clouds and identify these segments according to their geometric features and physical properties of targeting objects.The Hough transform and the least squares method are used to extract lines and circles from laser point clouds of ancient architecture.The effectiveness of these two kinds of algorithms is compared and tested with real data.Several experimental results are presented as well.
