基于视觉暂留原理的夜间会车防眩目系统

Anti-dazzling System for Automobile Night Meeting Based on Persistence of Vision

针对汽车夜间会车时,由于不规范使用远光灯而引起对向驾驶员眩目导致交通事故的问题,设计了一种基于人眼视觉暂留原理的夜间会车防眩目系统。该系统基于所有车辆的前挡风玻璃和前照灯灯罩玻璃均采用调光玻璃,夜间会车时,系统的电控模块根据车载传感装置接收的相关信息,控制调光玻璃交替透明,并使同一辆车的前挡风玻璃和前照灯灯罩玻璃透明状态相同,而与对向来车相应玻璃透明状态刚好相反且周期性变化,避免了车辆前照灯灯光射入驾驶员眼睛。又由于人眼的视觉暂留原理,玻璃交替透明的频率只要大于24Hz,人眼就察觉不到这一交替过程,从而保证驾驶员视觉的连续性。这样该系统既巧妙地解决了夜间会车眩目问题,又保证了行车安全。

Against the problem of the traffic accident caused by the dazzling which is due to unreasonable using the high beam light when automobiles meeting at night,designed the anti-dazzling system for automobile night meeting based on persistence of vision. The system is based on the condition which the front windshield and lampshade glass of headlamps in all automobiles were made of tunable glass. When meeting at night,used the sensors equipped in automobile to collect information,and controlled tunable glass turn transparent alternately. Then the front windshield and lampshade glass of headlamps in one automobile had the same transparent condition,but contrary to the coming automobile. And the transparent condition change in turn. It avoided the headlamps light hitting the two drivers＇ eyes. For the persistence of vision,people couldn＇t detect the processes as long as the twinkle rate is more than 24 Hz. Thus the dazzling problem when automobile meeting at night is solved as well as the driving safety is ensured.
