Research on the measurement of Road Icing Thickness by Infrared laser detection technology

The research of road icing thickness can provide a strong guarantee for vehicle driving safety in ice and snow days. The thicker the ice layer, the lower the wheel friction, the greater the probability of traffic accidents. In this paper, based on the spectral characteristics of ice, an ice thickness measurement algorithm based on differential method is derived. The detection angle is determined by the phase transition process of ice. The laser reflection detection method is used for experimental verification. The experimental results show that the method of dual wavelength cooperative detection of ice thickness can effectively measure the ice thickness, with the characteristics of low cost and low power consumption.
