| Abstract: | Airborne point cloud data is widely used in three￣dimensional modeling of the city and DEM extraction and the filter of airborne point cloud data is a primary of these applications. Therefore the physical characteristics of ground points and the methods of evaluating the accuracy of filtering results for filtering algorithm design are summarized and the categories of existing filtering algorithms are described. Finally the intuitive comparison and analysis are introduced especially and the prospect is also given to provide references for future research. |
