Abstract

Abstract: It is of great significance to conduct emergency surveying and mapping based on unmanned helicopter. But at present, there is a lack of surveying and mapping quality inspection system and quantitative indicators for unmanned helicopter aerial photography system. This paper proposes a survey and mapping quality inspection system based on Z-5 unmanned helicopter and supporting aerial photography system, including digital aerial photography results inspection, aerial three encryption results inspection and digital orthophoto results inspection. At the same time, this paper defines the quantitative data of important indicators. Through the actual flight verification, the aerial photography system based on Z-5 unmanned helicopter can meet the requirements of surveying and mapping accuracy.Four of them can further improve the threshold of quantitative indicators, so as to meet the requirements of more accurate UAV mapping.

Key words: Z-5 unmanned helicopter, surveying and mapping quality inspection, digital aerial photography, aerial triangulation, digital orthophoto
