A hierarchical contour method for automatic 3D city reconstruction from LiDAR data

摘要

Recent years LiDAR (Light Detection and Ranging) data is widely used for constructing 3D terrain models which provide realistic impressions of the urban environment. This paper presents a hierarchical contour method for building boundary extraction and 3D reconstruction from LiDAR Data. This method provides acceptable visualization for large-scale poor quality LiDAR data reconstruction.
