残差绝对值和最小法在单线阵CCD卫星影像后方交会粗差探测中的应用

The Application of the Adjustment Model of Minimizing the Sum of Absolute Residuals in Gross Error Detection of Linear Array Satellitic Scanner Imagery Resection

利用残差绝对值和最小法进行单线阵CCD卫星影像的后方交会 ,一般来说 ,不仅可以克服外方位元素之间的强相关性 ,而且可以有效地剔除粗差。实验证明该方法简便、稳健、有效。

Generally, the application of the adjustment model of minimizing the sum of absolute residuals in satellitic linear array scanner imagery resection not only can overcome the strong relativity of exterior orientation elements, but also can eliminate gross error effectively. Experiments evince this method is very simple, steady and effective.
