无人机影像处理技术在大比例尺基础测绘工程中的应用研究

摘要

UAV,as a rapid way to acquire high resolute stereo image,has been widely used with the advantage of low cost,high speed,little limitation and high resolution.The paper takes the example of remote and minority areas to compare the UAV aerophotogrammetry data processing,analyzes DLG production method,tests DLG result accuracy and summarizes the application of the UAV aerophotogrammetry technology in the large-scale fundamental surveying and mapping project.%无人机摄影作为一种快速获取高分辨率立体影像的方式,近几年来得到了广泛应用.其优点是成本低、速度快、受限制小、分辨率高,因而可广泛用于大比例尺航测成图.本文以边远地区、少数民族地区基础测绘专项补助经费项目——东宁县基础测绘工程实验项目为实例,对无人机航摄数据处理的作业流程作了分析与比较,分析了DLG产生方法,运用外业实测数据检测了DLG成果精度情况,最后对无人机航摄技术在大比例尺基础测绘工程中的应用作了总结.
