微光与红外图像融合质量视觉评价实验

Visual Assessment Experiments on Quality of Low Level Light and Infra-red Fused Imagery

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。然而,有关彩色/灰度融合图像的质量问题尚未形成一致的认识。近年来国外典型的夜视融合图像视觉评价实验表明:融合图像在大多数视觉任务中均优于单波段图像,但融合图像质量不仅与视觉任务相关,也与融合算法和获取图像条件等诸多因素有关。这些实验对于国内开展夜视图像融合技术和系统具有重要的参考意义。

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. However, no consensus has yet been derived for the quality of chromatic/achromatic fusion imagery. In recent years, foreign visual assessment experiments on typical night vision fusion imagery show that fused imageries are superior to conventional single-band imageries in most visual tasks,and the quality of fused imagery is not only related to the visual task, but also to many factors such as the fusion algorithm and the conditions to obtain the images. These experiments have important significance for reference in domestic development of night vision image fusion technology and system.
