ADS40影像处理及精度评估

Image processing and accuracy evaluation of ADS40

本文介绍了ADS40相机的结构及其工作流程,描述了其成像模型,并利用Leica公司的ORIMA软件,结合嵩山摄影测量与遥感定标综合实验场的ADS40影像,分析和评估ADS40相机在不同控制点数量、不同航线结构、不同附加参数下的几何精度。实验结果表明,使用少量控制点与自检校模型可极大地提高ADS40定位精度。

This paper introduced the construction and workflow of ADS40 camera, and described its imaging model. By using ORIMA software of Leica company and combining Songshan photogrammetry and ADS40 image of remote sensing calibration integrated experimental field, it analyzed and assessed geometric accuracy of ADS40 camera in different number of control points, different route structure and different additional parameters. The experimental result showed that it could immensely improve locational accuracy of ADS40 by using less control points and self-checking model.
