Paper Abstract
The traditional LiDAR Point Cloud filtering and classification algorithms are mostly based on the
elevation information, which are difficult to distinguish bare-ground and non-ground point with this
single data source. In this article, fused image information such is used in the filtering process. Through
the image segmentation, each segmentation object are extracted with the shape and spectral
information, then these vector space objects and point cloud are matched and the decision tree is set up
based on topology relationship for filtering. In order to test the performance of the proposed algorithm,
test area with thick buildings and roads were applied, which could achieve a better filtering effect.
