Geometric information is one of the important elements in describing the ground surface. And retrieval of geometric information is also a main objective of remote sensing. Now, multi-angle remote sensing, which is a new direction of remote sensing development, offers a new approach to improve the accuracy of geometric information retrieval. In this paper, several key techniques in the process of retrieving geometric information of ground surface based on multi-angle remote sensing are discussed in both theoretical and experimental aspects.Taking advantage of new remote sensing techniques that provide more information for sensor status, a new relative orientation method is advanced proposed in chapter 2, which uses the IMU/GPS measures as a constraint in the optimization process. In comparison with the traditional method, the new method combines two kinds of information: stereo conjugate points and direct measurements of the exterior orientation elements. Therefore, how to choose... |
