| 摘 要： | 后方交会法解求 SPOT卫星影像的外方位元素时 ,其法方程系数矩阵经常产生很严重的病态 ,若用最小二乘法估计 ,参数解将明显偏离真值 ,甚至无法解得外方位元素。本文中提出了用最小二乘岭估计的方法解求外方位元素 ,实验证明这是非常有效的。

| Abstract: | The Problem of ill conditioned Matrix often occurred on the heel of inverse computation for the exterior orientation elements of SPOT image. Especially when least squares estimation is used, the true values of exterior orientation elements might not be obtained. In this paper, ridge regression, a new method of computing exterior orientation elements of SPOT image is introduced, and it has been verified through practice. |
