Accurate and Automatic Building Roof Extraction Using Neighborhood Information of Point Clouds

Accurate and Automatic Building Roof Extraction Using Neighborhood Information of Point Clouds

High accuracy building roof extraction from LiDAR data is the key to build topological relationship of building roofs and reconstruct buildings. Aiming at the poor adaptation and low extraction precision of existing roof extraction methods for complex building, an accurate and automatic building roo...
