Space resection of SPOT image

There are two difficult points for the SPOT image data processing. The one is the calculation of its exterior elements between which there is strong correlation. The other is that the SPOT image has no epipolar line with strict sense, so the traditional epipolar correlation can not be applied actually. In this paper the Radio regression is presented to overcome their correlation and calculate the exterior elements. The results of from experiments show that the method is stable and with high accurate result. For the second problem this paper tested the matching scheme named 'anchor point,' which is a kind of two-dimensional matching method with multilayer control. Experiments show that it has the character of high speed and accurate.
