UAV Photogrammetry for Generating 3D Campus Model

摘要

Unmanned Aerial Vehicle (UAV) is increasingly popular as platforms for inspection, professional mapping, and modeling issues. UAV as a low-cost alternative to the classical manned aerial photogrammetry can survey buildings of various heights to take the necessary angle for a favorable photo. This paper presents results of using 3D reconstruction technique based on 2D pictures of a building taken by UAV. Automation and feasible image orientation create images to be processed in the latest developments of UAV image processing methods for photogrammetric applications, mapping, and 3D modeling issues. Images from a campus building construction in Bandung was taken for a case study using UAV with an attached camera. The images were processed to generate a 3D model of campus building using several integrated software. The integrated software was used to create image processing, mapping, orthophoto, and meshing. By using the proposed setting of altitude, overlapping percentage, direction of flight, the results show good quality of regenerated images which contain information of altitude and position of the building.
