| 摘 要： | 基于离散小波变换(DWT)理论,提出了一种基于场景的红外焦平面阵列(IRFPA)非均匀性实时校正算法;针对算法所涉及的运算量和数据量庞大的特点,设计了实时非均匀性校正的红外图像处理系统,系统是以高性能DSP(TMS320C6713)为核心器件,采用DSP不同的传输通道并行传输数据,并充分利用DSP硬件的并行性和流水线操作进行非均匀性校正;以真实的红外图像序列为例,进行了非均匀性校正的仿真实验,结果表明,基于高性能DSP的非均匀性实时校正系统完全可以达到实时校正的要求,所用算法对慢变化量具有较好的自适应性。

| Abstract: | Based on the theory of discrete wavelet transform,a scene-based nonuniformity-correction algorithm for infrared focal plane arrays(IRFPA) is presented.In this scheme,the infrared image sequence is decomposed to the discrete sequence wavelet transform with an appropriate wavelet function,and an operation flow based on Mallat algorithm is given,and an infrared imaging system is designed to carry out real-time nonuniformity-correction.The system uses high-performance DSP(TMS320C6713) as the core processor,and ... |
