多波长红外激光道路积水结冰厚度测量方法研究
Journal: Building Technology Research DOI: 10.12238/btr.v7i2.4234
Abstract
车辆制动能力是影响行驶安全的关键变量,随着道路积水、结冰厚度增加,制动距离将大幅上升,极易引发交通事故。因此,准确测量路面冰水厚度,进而估计路面湿滑系数,是实现道路安全预警的重要手段。本文针对以往激光路面气象测量技术中存在的参数标定次数多、冰厚测量困难、精度偏低等问题,以朗伯比尔定律为基础,通过分析水、冰的光谱特征,建立路面冰水厚度测量模型,引入多波长激光差分测量法降低冰面反射光干扰,实现了积水厚度和结冰厚度的可靠解算。
