Critical Points Extraction from Building Façades by Analyzing Gradient Structure Tensor

Critical Points Extraction from Building Façades by Analyzing Gradient Structure Tensor

This paper proposes a building façade contouring method from LiDAR (Light Detection and Ranging) scans and photogrammetric point clouds. To this end, we calculate the confidence property at multiple scales for an individual point cloud to measure the point cloud’s quality. The confidence property is...
