摘　　要：针对红外成像系统在图像处理中所涉及的数据量大 ,实时处理难于实现的特点 ,利用高速DSP硬件对红外焦平面阵列的非均匀性进行实时压缩校正 以两点校正为例 ,详细阐述了硬件压缩校正原理和实现步骤 ,并给出实验结果 实验表明 :基于DSP的非均匀性实时压缩校正系统生成的图像比较清晰 ,校正过程简单 ,程序调试方便 。Because of large amounts of image data and difficultly implementing real time image processing, a hardware system based on high performance TMS320C6201 DSP is presented. It can fulfill real time compressing correction of IR image nonuniformity. According to two points correction formula, the hardware correction principle and the specific steps are described in the paper. Experimental results prove that Its imaging quality is satisfying, the correction method is simple and the program debug is convenience. This way can effectively solve real time problem in infrared image processing.
