 UEV platforms are increasingly used for data collection and inspection, surveillance, mapping, and 3D modeling due to their low cost and ability to fly in various modes. With a photogrammetric pipeline, 3D results such as DSM slash DTM, counterlines, textured 3D models, vector data, etc., can be produced automatically. However, accurate feature extraction is still an interactive process, while new perspectives are also being explored. This article was authored by F. Riemondino, L. Barazzetti, F. Nex, and others.
