| 摘 要： | CCD卫星影像空间后方交会时，存在系数矩阵列向量间的强相关的问题，用光束法平差同样存在这个问题，将光束法平差与线角元素分求法、广义岭估计、附有限制条件的平差结合，证实三种方法都可以克服平差时外元素和变率改正数震荡大的缺点，并且取得了合理的空间后方交会精度和地面点定位精度。

| Abstract: | The same problem exists in bundle adjustment.This paper combined bundle adjustment with line and angle respectively computing,generalized ridge estimation and indirect adjustment of observation with condition.Demonstrations show that the three methods can overcome shortcomings that exterior orientation and variability shaking heavily in adjustment.The rational space resection accuracy and point accuracy on ground are obtained. |
