红外焦平面阵列非均匀校正算法的ASIC设计

Design of IRFPA Nonuniformity Correction Algorithm Using ASIC

红外焦平面阵列响应率的非均匀性是制约红外成像质量的主要因素。考虑实时处理的需要,基于温度定标两点校正法,进行ASIC设计。在阐述芯片结构基础上介绍各种模式功能。ASIC设计具有实时性好、体积小、性价比高的优点,适用于红外成像系统进行高速实时处理。最后给出在具有自主知识产权SoC芯片Garifield4上的算法验证结果。

The key quality point which effect IR image is nonunifomity of Infrared Focal Plane Array（IRFPA）. Here think about the requirement of real -time, to make Application Specific Integrated Circuit（ASIC） based on two - point nonuniform correction algorithm. This article introduces chip＇s structure and mode＇s functions. ASIC design has advantages of good real - time, small size and high quality with low cost. It is suit for processing image at high speed real - time in IR imaging system. The algorithm has been verified at Garifield4 which is designed by national ASIC system research center of Southeast University.
