摘要
针对热像仪普遍存在的暗角噪声进行了分析,提出了一种基于参考辐射源进行暗角噪声补偿的方法。探讨了传统非均匀性校正方法对暗角噪声进行补偿的优劣性,并提出了一种改进的神经网络校正算法。基于Retinex理论提出了一种基于单帧图像快速去除暗角噪声的方法,实验结果表明,该算法可以有效去除暗角噪声。
A dark-corner compensation method based on reference source is proposed in this paper, following the analysis of the multi-view thermal imager dark-corner noise. The superiority-inferiority of NUC algorithm is discussed based on multi-frame images to solve the problem of the dark-corner noise, and improve the NUC algorithm based on neural network. A fast algorithm of removing dark-corner noise based on single frame image is also introduced in this paper. The experimental results show that the proposed algorithm can remove dark-corner noise effectively.
