Building Change Detection in Airborne Laser Scanning and Dense Image Matching Point Clouds Using a Residual Neural Network

Politz, F.; Sester, M. (Katlenburg-Lindau : Copernicus Publications, 2022)

National Mapping Agencies (NMAs) acquire nation-wide point cloud data from Airborne Laser Scanning (ALS) sensors as well as using Dense Image Matching (DIM) on aerial images. As these datasets are often captured years ...
Exploring ALS and DIM data for semantic segmentation using CNNs

Politz, F.; Sester, M. (Katlenburg-Lindau : Copernicus Publications, 2018)

Over the past years, the algorithms for dense image matching (DIM) to obtain point clouds from aerial images improved significantly. Consequently, DIM point clouds are now a good alternative to the established Airborne ...
Joint classification of ALS and DIM point clouds

Politz, F.; Sester, M. (Göttingen : Copernicus GmbH, 2019)

National mapping agencies (NMAs) have to acquire nation-wide Digital Terrain Models on a regular basis as part of their obligations to provide up-to-date data. Point clouds from Airborne Laser Scanning (ALS) are an important ...
