Research on 3D model construction and path planning algorithm based on UAV tilt photogrammetry technology

Abstract The drone oblique photogrammetry technology has been widely used in military and civilian fields due to its advanced positioning technology, rich image information, and accurate geographic information. This article proposes solutions based on the “point set affine registration (ICP) with control point consistency constraints [1] ” and “adaptive chaotic particle swarm optimization (SACPSO) [2] ” algorithms to address the problems of “extremely difficult image point set registration” and “common iterative algorithm population easily falling into local optima” when using unmanned aerial vehicle (UAV) oblique photogrammetry technology for high simulation real-world 3D model construction and path planning.
