Application of laser sensor in urban vehicle type detection

Abstract

With the development of urban transportation, more and more traffic accidents happened, most of which were caused by ultra-high vehicles, which not only damaged the road facilities, but also endangered the safety of the masses. In this study, a vehicle height detection system was designed and applied to urban transportation to prevent such accidents. The system utilized the laser light curtain principle of the laser sensor to accurately detect the height of vehicles, equipped with an optical signal anti - interference system and an anti - collision alarm system. The experimental results showed that the system could effectively detect the unqualified vehicles and give alarms, which provided a reference for the application of laser sensor in urban road traffic detection.
