红外焦平面器件非均匀性校正的FPGA实现

Implementation of IRFPA Non-Uniformity Correction by Using FPGA

提出了一种基于FPGA的红外焦平面非均匀性校正的实现方案。在系统中,采用基于黑体的两点校正的方案。另外,校正参数的获取,可以采用两种工作模式,通过存储器下载和在线计算校正参数。实验表明,这种解决方案可以实时完成校正处理,并有效地抑制了器件的非均匀性。

A novel resolution of IRFPA non-uniformity correction by using a FPGA. In this implementation, two-point non-uniformity correction （TPNUC） method is used, and two alternatives of acquiring the correction parameters are also introduced. The results have indicated that TPNUC can be processed in real-time, and the non- uniformity is suppressed effectively.
