Piattaforme UAV per applicazioni geomatiche

Un’alternativa efficiente, veloce e low-cost al tradizionale rilievo aereo, ma ancora senza una regolamentazione chiara e con alcuni problemi di stabilità e payload. UAV platforms for geomatics UAV platforms are nowadays a valuable source of data for inspection, surveillance, mapping and 3D modeling issues. New applications in the short- and close-range domain are intro-duced, being the UAVs a low-cost alternatives to the classical manned aerial photogrammetry. Rotary or fixed wing UAVs, capable of performing the photogrammetric data acquisition with amateur 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. The article reports the latest developments of UAV image processing methods for photogrammetric applications with also some insight on regulation and system certifications.
