Nonuniformity Correction of Real-time Infrared Image Based on DSP

根据实时图像处理的基本要求,对红外图像的非均匀性校正进行了深入的研究,分析了两点校正的原理,介绍了实现的方法,并结合DSP硬件具有强大的运算能力及灵活的可编程性的特点,设计了红外图像的非均匀性实时校正系统的构成,描述了校正方法的实现过程用像元数为120×160的红外焦平面阵列进行了图像非均匀性实时校正实验,并对校正前后的图像进行了对比,实验结果达到了预期目的。

In this paper, according to the request of real-time image processing, the nonuniformity.correction of infrared image is studied. The principle of two-point correction is analyzed and the main method is introduced. A two-point correction method which makes use of the powerful computational capability and good programmability of DSP hardware is therefore proposed to do the real time correction of infrared image. Experimental results showed that the infrared image nonuniformity real time correction system based on DSP can do the correction to satisfactory results.
