3DGeo contributions to ISPRS Congress 2022 now online

From 5 June – 11 June 2022 the ISPRS Congress took place in Nice, France. The 3DGeo research group had three paper contributions which can now be found online:

(1) Virtual Laser Scanning of Dynamic Scenes Created From Real 4D Topographic Point Cloud Data.

4D object-by-change (4D-OBC) extracted at an example location of detected changes. a) Time series of changes with 4D-OBC timespan marked by red vertical lines. The location of the time series in the scene is marked in (b). Close-up maps show bitemporal changes at (c) the detected start and (d) the detected end epoch with the spatial extent of the 4D-OBC (red polygon).

(3) Evaluation of UAV-borne photogrammetry and UAV-borne laser scanning for 3D topographic change analysis of an active rock glacier.
