摘要
为农村土地确权登记发证，以湖北省1：2000基础影像数据DOM制作项目为例，介绍了基于POS辅助空三在大比例尺山地测区的像控布点方案和加密方法，并对测区范围的空三成果进行精度检查和统计分析。结果表明，对于山地测区，在外业布设25-30条基线一对像控点的条件下，利用POS辅助空三测量，空三加密精度可以达到1：2000大比例尺成图要求。
Taking the procedure of Hubei Rural Land owner- ship 1：2 000 map generating as an example, this paper introduces specific details on aero triangulation generating proce- dure in mountainous region by POS and laying-point method of photograph control survey, discusses the evaluation from the accuracy and efficiency of aero triangulation. And the results con- firms that the accuracy meets the requirement of large sale mapping in mountainous region when using laying-point method 20- 30 baseline with POS.
