基于各向异性加权的红外导引头非均匀校正

红外导引头探测器成像的非均匀性严重影响探测性能。针对红外导引头非均匀校正命题,提出了一种基于各向异性加权的红外导引头非均匀性校正算法。首先,简要阐述了红外成像系统的响应模型,分析非均匀校正和图像直方图之间的联系,进而,引入局部各向异性加权的直方图,形成一种高效的红外导引头非均匀校正算法。校正实验结果表明,与其他算法相比,所提出方法无论从实际视觉效果和客观质量评价,还是从处理速度,都具有明显优势。

Non-Uniformity Correction of Infrared Seeker Based onWeighted Anisotropic

The performance of the detection system is seriously affected by the non-uniformity characteristics of infrared seeker imaging.A non-uniformity correction algorithm based on weighted anisotropic infrared seeker is proposed for the non-uniformity correction proposition of infrared seeker.Firstly,the response model of infrared imaging system is briefly described,and the connection between the non-uniformity and the image histogram is analyzed,furthermore,the local weighted anisotropic histogram is introduced,forming a highly performance infrared seeker non-uniformity correction algorithm.The experimental results show that compared with other algorithms,the proposed method has obvious advantages both in terms of actual visual effect and objective quality evaluation,as well as the processing speed.
