ISPRS WG II/2

Point Cloud Generation and Processing

Our Mission

ISPRS Working Group II/2 addresses the development of new methodologies, algorithms and applications for point cloud generation and processing. We address point clouds acquired by photogrammetry and LiDAR as well as other scanning technologies and ubiquitous 3D sensors. The data can be captured by terrestrial including indoor, airborne including UAV and space-borne platforms. The processing includes filtering, feature extraction, object detection, segmentation, classification, registration and fusion of point clouds from different sensors and data sources as well as mesh-generation during surface reconstruction. Along with classic applications in mapping, point clouds for BIM and CH are also addressed.
