A Matching-Based Automatic Registration for Remotely Sensed Imagery

How to register and rectify the multi-resource images of remote sensing is becomes one of the urgent problems in the field of earth observation and information acquirement recently. To meet this requirement of multi-source image application, an automatic imagery registration algorithm based on image matching was proposed and described, and an automatic registration workflow of multi-source remote sensing imagery was established and implemented in this paper. Many remote sensing images of SPOT5 (5 m), SPOT4 (10 m) and TM(30 m) which cover Hangzhou area were employed for the experimentation. It could be clearly indicated by the result that the algorithm and workflow designed here are precise, prompt, and practical for geometry registration.
