摘要: 国内倾斜摄影测量技术目前仍处于快速发展的推广阶段,其成果精度高度依赖于航测生产全流程中各航测参数的选取,很难实现对其绝对精度的定量分析。针对这一难点,本文采用对比分析的方式,以传统低空航测为参照,在严格统一外部数据采集条件、解算参数的基础上对无人机倾斜摄影测量进行精度评估与分析,探索无人机倾斜摄影测量的突出技术优势。试验共涉及12种主流航测模式及52种地面控制点,采用递进布设方式对比分析其成果精度,并完成了倾斜摄影测量对比传统低空航测的量化分析。本文可为倾斜摄影测量精度评估提供一定的参考,具有较好的工程实践指导意义。

Abstract: At present, the domestic tilt photogrammetry technology is still in the stage of rapid development and promotion, and its accuracy highly depends on the selection of aerial survey parameters in the whole process of aerial survey production, so it is difficult to realize the quantitative analysis of its absolute accuracy index. In view of this difficulty, this paper adopts the way of comparative analysis taking the traditional low altitude aerial survey as the reference, on the basis of strictly unified the external data acquisition conditions and solving parameters, evaluates and analyzes the accuracy of unmanned aerial vehicle (UAV) tilt photogrammetry, and explores the outstanding technical advantages of UAV tilt photogrammetry. The experiment involves 12 kinds of mainstream aerial survey modes and 52 kinds of progressive layout of ground control points in order to compare and analyze the accuracy index of the results, and complete the quantitative analysis of tilt photogrammetry compared with traditional low altitude aerial survey. This study can provide certain reference and practical guidance for the accuracy evaluation of tilt photogrammetry.
