To obtain better measuring results, A multi-steps matching method is proposed to improve registration accuracy progressively for InSAR complex image. Firstly calculate the approximate offsets by using software EnView. Then perform pixel level’s primary matching and sub-pixel level’s precise registration. The primary matching algorithm based on texture structure information. Considering that the presented algorithms are based on the amplitude map and ignore the integration, the algorithm by using global relaxation matching on account of the phase is proposed in the last matching step to reduce the matching errors and improve matching precision. The experiment verified the nicer validity of this algorithm. 关键词： edge extraction, global relaxation,phase, registration,InSAR (浏览全文) 发表日期： 2006年11月30日 同行评议：
