摘　　要：为了减少超高车辆所造成的交通事故,本文基于相位式激光测距原理,设计了单机可探测多条车道的激光车辆限高仪。实验表明此系统能够准确判断高度,分辨车道精度达到±5cm,已经高于实际使用的要求。In order to reduce the traffic accident caused by over high vehicles, a new design of laser height-limiting instrument based on laser phase-shift rang finding is introduced in the paper. The main feature of the design is that one instrument can detect several roadways. The experiment shows that the system could judge height precisely, which achieves ±5cm precision in detecting roadway, and exceeds the practical application requirement.
