Abstract

Abstract

Unmanned aerial vehicle (UAV) is used to take photogrammetry in a simple geomorphology area,and the photos are calculated by professional triangulation software.The unqualified triangulation result is solved by take redundant multi-scale aerial images and calculated by combined triangulation once more.The three-dimensional(3D) model’s accuracy is improved to meet the accuracy requirements in large-scale topographic mapping using UVA photogrammetry model.
