摘要
阐述了低空航测系统的发展现状和系统组成,探讨了利用该系统进行航测作业的技术流程,并进行了DLG、DEM和DOM数字产品生产实验,最后对成果进行精度评定和可行性分析。结果表明,低空影像可用于小区域的大比例尺快速地形测绘。
This paper described the development and system components of low-altitude photogrammetry,and investigated the technical process of photogrammetry operations by using the system.Then it made the digital production test for the DLG,DEM and DOM.Finally,it made the accuracy assessment and feasibility analysis on the results.The results show that low-level image can be used for small areas of large-scale rapid topographic mapping.
