摘要：Since HuanJing(HJ)-satellite has been sent successfully in September 6, 2008, in china, productions of precise geometric correction are imminently needed. Moreover, the demand for rapid processing of remote sensing data for disaster is increasing. Aiming at the characteristics of HJ-CCD imagery, a precise geometric correction technology workflow has been designed, which is a very meaningful work. It mainly includes three parts: image control point ( ICP) database construction, automatic image matching and geometric correction model. SIFT algorithm and template matching method are employed to match images and polynomial correction with tiny facet of geometric correction model is employed to correct images. We do experiments using our developed prototype system to correct one scene image of HJ-CCD data. Image matching results of two matching methods above are shown and geometric correction results are shown respectively
