A FAST AND ROBUST ALGORITHM FOR ROAD EDGES EXTRACTION FROM LIDAR DATA
Mobile Mapping Systems (MMS) LiDAR data Point clouds Road edges extraction Rough plane Refined plane
2016/11/11
Fast mapping of roads plays an important role in many geospatial applications, such as infrastructure planning, traffic monitoring, and driver assistance. How to extract various road edges fast and ro...
A Method for Urban Buildings Change Detection Based on Vertical Edges Extraction
Vertical Edge Change Detection Vanishing Point Photogrammetry Edge Extracting Line Detection
2015/12/9
This paper proposes a method for buildings change detection. Vertical edges of buildings are extracted in pairs of aerial images respectively, taking advantage of the character that vertical edges int...
SURFACE DISCONTINUITY MODELLING BY LSM THROUGH PATCH ADAPTATION AND USE OF EDGES
