Application of Domestic Satellite Image Fast Ortho-Rectification Method in Dynamic Remote Sensing Monitoring of Sea Area

To cater for the need for dynamic remote sensing monitoring in the sea area and the characteristics of the domestic high-resolution satellite imagery in coastal areas, a set of effective and fast ortho-rectification methods based on PCI Geoimaging Accelerator (GXL) system are developed in this paper. The technical flow generated and parameters setting of key technological linkages are described in details. Upon the application in actual production and the analysis of production efficiency of GXL, the automatic and fast ortho-rectification method of domestic satellite imagery based on dynamic remote sensing monitoring in the sea area is further demonstrated to meet the business needs.
