摘要
道路能见度检测是智能交通的一个重要的组成部分。在比较系统地阐述了可用于道路能见度监测的方法及特点的基础上,提出了一种改进的散射光测量方法,实验表明:该方法具有前向散射法优点,同时,可大大减少环境灰尘、激光器老化引起功率下降等因素对系统的影响,可提高系统测量的可靠性。
Visibility monitoring on road is an important part of intelligent transportation system. The method and characteristic of visibility monitoring on road are introduced systematically.An improved measurement method of scattered light is presented.The experiment expresses that the new method has the forward-scattering method advantage,and can reduce the influence of the environment dust,and the power descent etc caused by the laser machine ageing on the system. It also can increase the system measuring reliability.
