UAV photogrammetry method improves 3D reconstruction accuracy

Researchers have developed a new iterative hybrid discrete-continuous viewpoint planning method specifically for unmanned aerial vehicle (UAV) photogrammetry. This method aims to improve reconstruction accuracy and completeness by optimizing camera networks for better surface coverage, image overlap, and parallax. The approach scores sampled points using photogrammetric heuristics and evaluates viewpoints for visibility and overlap, generating and refining candidate viewpoints around under-observed regions. The final flight path balances detailed local reconstruction with robust global image-network coverage, outperforming prior methods in synthetic scene evaluations. AI
