Learn how to process UAV imagery in Agisoft PhotoScan to produce highly accurate DTM , orthomosaic & 3D model. ( UAV image processing )UAV platforms are nowadays a valuable source of data for inspection, surveillance, mapping and 3D modeling. New applications in the short-and close-range domain are introduced, being the UAVs low-cost alternatives to the classical manned aerial photogrammetry. Rotary or fixed wing UAVs, capable of performing the photogrammetric data acquisition with Consumer grade or SLR digital cameras, can fly in manual, semi-automated and autonomous modes. With a typical photogrammetric pipeline, 3D results like DSM/DTM, contour lines, textured 3D models, vector data, etc. can be produced, in a reasonable automated way.
