摘要

In this paper, we propose a new scene-based non-uniformity correction algorithm based on FPGA. We focus on the real application and the non-uniformity performance of the IR imager system and we did the research of the defects of other non-uniformity correction algorithms which had already been reported nowdays and found out that most of them can only be used in the lab. The scene set for these algorithms often fits themselves in most cases. In real application, the scene is mostly towards one continuous monotonous direction and has different appearance of non-uniformity. We solve these problems by developing a new projection estimator for the registration with a criterion, and immigrate this algorithm into a FPGA_based hardware system. This system is fully engineered for some particular usage. We test the performance of our technology by the evaluation indexes, and demonstrate the actual effect of correcting the non-uniformity under a monotonous motion on the system. At the end of this paper, we make a conclusion and perspective of our research work.
