摘　　要：小型无人机航测技术的发展为测绘及相关领域提供了灵活、高效、智能的技术手段,但因飞行能力的问题,在大片区作业中应用受限。本文基于济钢片区倾斜摄影模型对大片区作业无人机航测高程精度进行研究,根据像控点分布特征,分区域对无人机航测高程与检测高程进行比较,给出高程精度分析表,并对高差分布特征进行分析研究,以此验证无人机航测高程精度的可靠性。The development of small UAV aerial survey technology provides flexible,efficient and intelligent technical means for surveying and mapping and related fields.However,due to the problem of flight capability,its application in large area operations is limited.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.
