F.Leberl模型与干涉测量模型相结合的InSAR影像区域网平差
Block adjustment of InSAR images based on the combination of F.Leberl and interferometric models
摘要
Abstract
In order to solve the problem of lacking control points during the process of western mapping, this paper presents a new method of block adjustment for interferometric synthetic aperture radar (InSAR) images. This method combines the F. Leberl model and the interferometric model. The alternative approximation method as well as LDL' split coefficient matrix method is also used to calculate the large scale normal equation. The experimental results show that the precision of block adjustment is higher with the new method compared with the traditional method based on F. Leberl model. By adding three calibration parameters, the block adjustment of amplitude images and digital elevation model (DEM) could be realized at the same time. At last, the factors that influence the precision of block adjustment are analyzed in detail by using the actual InSAR parameters.关键词
