摘要
介绍了三线阵数码航摄仪ADS 80,探讨了其Level 0级影像的后处理技术,分析了不同软件在相同地面分辨率下不同地面控制条件下的后处理精度。得出的结论是控制点分布、数量、位置和航摄影像地面分辨率对ADS 80相机L0级影像空三解算和生成的L1级影像精度影响较大;在充分考虑以上因素的情况下,ADS 80相机在获取的航摄影像地面分辨率低于成图比例尺要求时仍能得到较高的校正精度。
This paper introduces three linear array camera ADS80,discusses data post-processing techniques of its Level 0 images,analyzes the accuracy by different software under the same ground resolution but different ground control conditions,and draws the conclusions that the accuracy effects on L0 level images aerial triangulation and produced L1 level images of ADS80 digital camera brought by distribution,quantity and position of ground control are big;If above factors are considered adequately,the higher accuracy can be achieved even the ground resolution lower than the requirements of mapping scale.
