UAV PHOTOGRAMMETRY FOR MAPPING AND 3D MODELING – CURRENT STATUS AND FUTURE PERSPECTIVES

TLDR

UAV platforms provide low‑cost, versatile data for inspection, surveillance, mapping, and 3D modeling, enabling automated generation of DSMs, DTMs, contour lines, textured models, and vector data from rotary or fixed‑wing aircraft equipped with amateur or SLR cameras. This paper reviews recent UAV image‑processing advances for photogrammetric mapping and 3D modeling, and discusses emerging perspectives. Abstract.

Abstract

Abstract. 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 introduced, 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 paper reports the latest developments of UAV image processing methods for photogrammetric applications, mapping and 3D modeling issues. Automation is nowadays necessary and feasible at the image orientation, DSM generation and orthophoto production stages, while accurate feature extraction is still an interactive procedure. New perspectives are also addressed.
