Abstract

Abstract

Lacking of GCPs (Ground Control Points) in hard survey area is one of the most difficult problems of geometric rectification. This paper proposes a new method of large SAR image-block adjustment based on F.leberl model. The parameters of the images and ground coordinate of pass points can be calculated with the use of alternative and iterative algorithm. The result shows that this method could get steady result with few GCPs and the error of tie points can also be decreased effectively, the accuracy reaches to the lever of single-image-calibration method.
