Image fusion technique is one of the important directions in current technological development of night vision, and chromatic night vision technology is especially the focus of research.

图像融合技术是当前夜视技术发展的重要方向之一,彩色夜视技术更是其中的研究重点。

The progress in research on algorithms for night vision color image fusion is introduced, with emphasis on the analysis of the MIT method which aims at nearly natural color, as well as the linear composite method and the mixed architecture method comprising the non linear image enhancement based on visual antagonism model and linear composite method, both of which are proposed by us.

介绍了夜视彩色图像融合算法的研究进展 ,着重分析了以接近自然色彩为目的的MIT法以及我们提出的线性组合法、基于视觉拮抗模型的非线性图像增强与线性组合法结合的混合结构法 ,给出了若干组场景下各方法的微光与热成像的彩色融合图像以及微光彩色融合图像 ,显示出良好的目视观察效果 ,提出了需要进一步研究的问题和关键技术。

Then a night vision fusion method was presented to improve target detectability by enhancing color contrast between the target and the background.

根据人眼视觉系统特性,分析了场景理解和目标探测对彩色融合的要求,并据此提出了一种通过颜色对比度增强来提高目标可探测性的夜视融合方法。
