Offshore Area Satellite Remote Sensing Images Location Method Based on Coastline Feature Matching
ZHU Ninglong;The 91404~(th) Unit of PLA;
Aiming at the information lack of satellite orbit, sensors attitude and so on, an offshore area satellite remote sensing images location method based on coastline feature matching was presented. First, seacoast interactive extraction of images to be located was done by the extending application of Live-Wire algorithm. Then, the curve form ideograph was improved to adapt seacoast line feature, and an optimized cure matching algorithm based on the ideograph was designed to realize seacoast curve matching. Finally, offshore area location of satellite remote sensing images was implemented by computing transform matrix according to the matching results. Localization experiments using Land Sat and SPOT images indicated that the algorithm was efficient.
