摘　　要：根据监视监控领域对低照度和隐蔽性的特殊要求,在热红外成像技术和微光夜视技术的基础上,研制开发了一种彩色(黑白)一体化的夜视摄像设备。首先描述系统的组成和结构,并分析光电部分的基本工作原理。提出的实时嵌入式彩色/灰度分离合成技术有效提高了视频图像的传输效率和信噪比。采取的窄带通光学滤波技术避免了信号的失真以及乱码等现象。基于小波变换的夜间图像增强算法极大提高了视频的可观测性。实验结果表明,该系统在主观视觉质量和客观评价指标2方面的表现均超越了某主流品牌,在国内外摄像技术领域处于领先水平。According to special requirements of low illumination and concealing in monitoring field,this paper develops a color（grayscale） integrated night vision system based on infrared thermal imaging technology and glimmer night-vision technology.System structure is firstly described,and basic operation principle for photoelectric part is then analyzed.A real-time embedded color / grayscale separation and integration strategy is adopted to efficiently improve video transmission efficiency and S / N ratio.Narrow band pass filter is used to avoid signal distortion.Afterwards,a wavelet-based night vision image enhancement algorithm is performed to increase video＇ s visual effect.Experimental results show that this system＇s performance surpasses a mainstream brand in terms of visual quality and objective values,and thus is at advanced levels in the field of video cameras both at home and abroad.
