A registration method of multi-temporal DSM from satellite dense matching
Accurate registration of DSM is a prerequisites for applications such as change detection using DSMs of different time periods.A registration method is proposed for multi-temporal DSM from dense matching in this paper.In this method,the rigid body transformation is used as transformation model,and 3D matching points are obtained based on 2D matching points form image matching.Then,based on the coarse registration model parameters,the sparse ICP method is used to obtain the fine registration model parameters.Experiment is conducted on two temporal DSM from satellite images,and experiment result shows that the method can achieve accurate registration of DSM effectively.
