摘　　要：在红外图像信息处理中,首先要对采集到的图像信号进行预处理。以SOFRADIR公司的320×240元红外探测器芯片为例,介绍基于DSP处理器和FPGA的图像预处理系统的硬件设计,以及图像预处理非均匀性算法的研究。在图像预处理系统的硬件平台上,通过采用非均匀性算法中的两点校正法,对所采集到的红外图像信号进行预处理,取得了较好的效果,证明了硬件系统的合理性和算法设计的可行性。During the processing of infrared image information, the sampled image information should be pre-processed at first. According to 320×240 infrared detection chip of SOFRADIR company, the hardware de- sign based on digital signal processor （DSP） and field programmable gate array （FPGA） image pre-processing system is introduced. And the non-uniformity algorithm of image pre-processing is researched. The collected infrared image signals is pre-processed on the hardware platform of image pre-processing system by two-point correction method of non-uniformity algorithm and better results are obtained. The rationality of the hardware system and the feasibility of the algorithm design are nroved.
