Abstract

Abstract: With the background of 1∶2000 aerial production task of one hidden danger spot of geological disasters in Shaanxi province, this paper combines the technical characteristics of Vtol UAV photography and the geographical situation of the spot area. By comparing advantages and disadvantages of several layouts, it aims to study the influence of UAV photography ground control points on aerial triangulation. Based on the geographical situations of different geological disasters, it comes to conclude the appropriate layouts of UAV photography ground control points for different hidden dangers of geological disasters, providing a reference for the same problem in the future.

Key words: UAV photography, layout of control points, hidden dangers of geological disasters, aerial triangulation, accuracy
