摘要
红外焦平面阵列(IRFPA)成像是当今红外成像技术发展的主流方向,然而IRFPA特有的非均匀性严重地限制了系统的成像质量。针对红外焦平面阵列在进行非均匀性校正中所涉及的运算量和数据量庞大、实时处理难于实现的特点,本文提出采用高速TMS320C6000系列DSP为核心的嵌入式硬件系统,结合分段线性和分段二次多项式算法,阐述了硬件设计和实现步骤,并给出实验结果,结果表明本系统完全满足实时高精度校正的要求。
The Infrared Focal Plane Arrays (IRFPA) imaging system is the main technique tendency of infrared imaging, but the inherent nonuniformity of IRFPA crucially limits its imaging quality. Because the operands and data volume are so vast that it is difficult to realize real-time processing in the Non-uniformity Correction (NUC) on the infrared focal plane, In the drop-in handware system, TMS320C6000 DSP was applied to resolve this problem, which combined Linearity and Second-degree Polynomial segment algorithms. The hardware design and implementation flow of the system was described and the experiment results were given. The results show the real-time non-uniformity correction system meets the real-time and high-precision requirements completely.
