摘要

The traditional ortho-rectification technique for remotely sensed imagery, which is performed on the basis of ground image processing platform, has been unable to meet the timeliness requirements. To solve this problem, this paper presents the research on ortho-rectification technique based on field programmable gate array (FPGA) platform, which can be implemented onboard and spaceborne for a real-time processing. Through comparing the correction accuracy and the consuming time of traditional ortho-rectification method with the proposed method based on FPGA, it is demonstrated that the proposed FPGA-based onboard orthorectification has great advantage over improving the image ortho-rectification speed and can reach the requirements of correction accuracy.
