A Method of Bridge Outline Extraction Based on Airborne LiDAR Data
Automatic and quickly extraction of bridge information from LiDAR data is of great significance in building 3D digital city and virtual earth. Especially the extraction of bridge outline is a crucial problem. It is a concern of many scholars research focus. This paper presented a method of bridge extraction using airborne LiDAR data. The biggest advantage of the method is based on priori-knowledge and by analyzing the spatial structural characteristics and geometric characteristics of the bridge. Experiments show that this method has a good accuracy compared with the result of expert interpretation.
