摘要
短于两条基线的三线阵影像平差,由于该平差系统几何条件较差,不可能有严格的数学解。本文提出基于等效框幅像片(简称EFP)的全航线三线交会的光束法平差。该平差方法采用特殊措施,即将平差分为两个步骤:①创造各种条件使法方程有解,但并不顾及平差航线模型可能有较大的系统变形;②将含有较大系统变形的航线模型数据与只含有较大偶然误差的航线模型初始值进行比较,从中提取航线模型系统值并加以改正。最后通过模拟数据和实际影像数据进行试验,取得了较好的结果。
Due to the poor geometric characteristics of the adjustment system,there will be no strict mathematical solution to the three linear array images shorter than two baselines.Therefore,the whole route adjustment of three intersection method based on the equivalent frame photo（EFP）is put forward in this paper.Special measures are taken in the method and the adjustment is divided into two steps.First step,various conditions are created for normal equation solution,while the obvious system deformation of adjustment course model is not taken into account.Second step,the comparison is made between the route model data containing larger system deformation and the initial value of route model containing larger accidental errors,and the system value of route model can be attracted and corrected.Finally,the tests using simulation data and real image data are conducted and good results are achieved.
