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DLG、DEM和DOM数字产品生产试验,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。
The development status and system components of the low-attitude aerial surveying system are described. Ttle technical flow of the system to be utilized fbr the aerial surveying operation is studied as well as the production tests of the digital products of DLG, DEM and DOM are performed. Finally, the results are evaluated and analyzed in terms of precision and feasibility. The study presents that the low-attitude image can be applied for the rapid topographic mapping, in a larger scale, of the small region.
