搭载POS的SWDC-4航摄试验分析

本文主要介绍了SWDC-4搭载POS的一次航飞试验情况,探讨二者集成工作的可行性以及POS精度的可靠性。通过传统空中三角测量(空三)加密方式与POS获取的每个摄站外方位元素进行对比与分析,探讨POS应用于SWDC-4的方式方法。结果表明:在精确检校出POS与相机安装的固定角度基础上,POS技术可以成功应用到SWDC-4相机上,而且有望取代空三加密的过程,大幅提高航测数据后处理的工作效率。

Analysis of SWDC-4 aerial test equipped with POS

This paper mainly describes the aerial test case of SWDC-4 equipped with POS,investigates the feasibility of integration with POS and SWDC-4 and the accuracy of POS.Comparing and analyzing the exterior orientation elements of each photo obtained from the method of aerial triangulation and POS,it concludes the application of ways and means for POS used in SWDC-4.The result shows that:in the basis of the accurate calibration angle of POS and camera,POS technology can be successfully applied to SWDC-4 camera,and it is expected to replace the process of aerial triangulation,which can highly improve the efficiency of data processing for aerial survey.
