为了提高夜间行车的视距范围，采用远距离红外照明成像技术研制了汽车主动式红外 夜视系统。经测试，在无光环境下，样机的视距可达到200m。本文深入总结了汽车主动式红外夜视系统的总体设计 技术，并对CCD摄像机和红外光源的关键参数进行了深入的分析与计算。文中的设计思路与设计方法可供相关 行业人员参考。

In order to increase the vision distance at night, an active infrared night vision system for automobile is developed. The prototype night vision system is tested and has a vision distance of up to 200m in complete darkness. In this paper, the design of the active infrared night vision is further summed up and the key parameters of a CCD camera and an infrared light source are further analyzed and calculated. The design idea and method can be offered to the researchers in related fields for reference.
