摘要:For the problem of block adjustment for satellite images, which cannot be solved under conditions of weak geometric convergence, this paper proposes a strategy that uses a planar block adjustment method to solve the orientation parameters of all satellite images, and then each satellite image is orthorectified. This strategy can ensure both the uniformity of the positioning accuracy and the strictness of the relative positions of the adjacent orthoimages. Tests of 139 panchromatic nadir images from the ZY-3 satellite show that by using only a small number of ground control points (GCPs), whose plane accuracy is 5 m, the plane accuracy of independent check points (ICPs) is better than 7 m after planar block adjustment. This accuracy meets the requirements for Chinese 1:50 000 topographic maps. Moreover, the preciseness of tie points (TPs) in adjacent images is better than 0.5 pixels, so a seamless level in mosaic geometry is attained.
