Abstract
Based on close photogrammetric technology,this paper proposes a progressive 3D modeling scheme tailored for the multi-eave characteristics of the tower.Low-resolution images are first acquired through multi-angle UAV surround flights to construct an initial model.Point cloud denoising and the Alpha Shapes algorithm are then employed to extract the building's outer contours.By integrating C#programming,automatic recognition of eave corner feature points and calculation of equidistant route control points are achieved,resulting in high-density KML flight paths for intelligent route planning.The experimental results show that close photogrammetry significantly improves the presentation of details in complex structures,validates its technical advantages in fine modeling of buildings,and provides an efficient solution for the digital protection of complex buildings.关键词
