摘要: 无人机摄影测量技术在弃土场监测中发挥重要作用,消费级无人机具有低门槛、低成本的显著优势,但利用消费级无人机进行摄影测量的精度分析研究较少,特别是2021年发布的最新《低空数字航空摄影测量内业规范》中对测量精度有更高的要求。本文以公路建设项目弃土场为研究对象,根据地面布设的像控点评估应用消费级无人机对其进行倾斜摄影测量的精度,并与传统正射摄影测量方式进行对比分析。试验结果表明,消费级无人机通过倾斜摄影测量精度能提高25.19%~90.68%,在高程上更为显著,同时能够消减因地形落差大对测量精度的影响,使其达到厘米级,符合规范中1∶500比例尺的成图要求,证实了消费级无人机在弃土场监测中的可靠性与可行性。

Abstract: UAV photogrammetry technology plays an important role in the monitoring of spoil ground.Consumer-grade drones have significant advantages of low threshold and low cost,but there are few studies on the accuracy analysis of photogrammetry using consumer-grade drones.In particular,the latest “specifications for office operation of low-altitude digital aerial photogrammetry” issued in 2021 has higher requirements for the accuracy of measurement.This paper takes the spoil ground of highway construction project as the research object,evaluates the accuracy of tilt photogrammetry using consumer-grade drones according to the image control points laid on the ground,and compares it with the traditional orthophoto grammetry.The test results show that the consumer-grade UAV can improve the measurement accuracy by 25.19%~ 90.68% through oblique photography,which is more significant in elevation.At the same time,the influence of large terrain drop on the measurement accuracy is reduced to centimeter level,which meets the mapping requirements of 1∶500 scale in the specification.The reliability and feasibility of consumer-grade UAV in the monitoring of spoil ground are proved.
