基于红外探测技术的汽车夜视系统研究

Car's night-vision system based on infrared detection technique

为了保证夜间及恶劣环境行车安全,提高驾驶员对前方目标识别的准确度,提出一种基于近红外成像技术的汽车夜视系统,该系统采用主动式近红外探测技术的车载夜视仪。系统主要由前端红外发射单元、红外线成像单元和图像显示单元组成。现场试验夜视系统识别漏检率为1.3%。实验结果表明传统车灯所辐射的大部分红外成分对夜间照明是无用的,可见光能效较低,而基于红外图像处理的汽车夜视系统能够有效地保证汽车安全驾驶。

In order to ensure the driving safety and enhance the discrimination accuracy,a car's night-vision system was put forward based on active near infrared detection technique.The system included the infrared emitting unit,infrared imaging unit,and image display unit.The loss rate of the system in field test was 1.3%.The experimental results imply that most infrared components in traditional automotive light are useless for night illumination,and the visible light energy efficiency is lower.The car's night-vision system based on infrared detection technique can ensure effectively driving security.
