Analysis and Research on Elevation Accuracy of UAV Aerial Survey in Jigang Area
The development of small UAV aerial survey technology provides flexible,efficient and intelligent technical means for sur-veying and mapping and related fields.However,due to the problem of flight capability,its application in large area operations is lim-ited.In this paper,the vertical accuracy of UAV operating in a large area is studied based on the oblique photography model of Jigang area.According to the distribution characteristics of image control points,the aerial elevation of UAV is compared with the inspection elevation in different regions,and the height difference distribution characteristics are analyzed to verify the reliability of UAV aerial survey vertical accuracy.
