| 摘 要： | 将四元数理论引入高分辨率线阵CCD影像的空间后方交会解算中,提出了一种利用四元数描述线阵CCD影像的单片空间后方交会方法。该方法利用四元数描述角度旋转矩阵,对严格的共线条件方程进行线性化,并采用正则化的数学方法克服线阵CCD影像外方位元素的相关性。试验证明了本算法的正确性和可靠性。

| Abstract: | The theory of quaternions is introduced into the field of photogrammetry.A new method which uses quaternions to describe the position and attitude of line scanner CCD image is presented.Firstly the quaternions are used to describe the rotation matrix in the algorithm.Then,the strict collinear equation is linearized,and at the same time the iteration by correcting characteristic value can effectively overcome the strong interrelationship among exterior elements.The numerical experiments were done.Results sho... |
