THE APPLICATION OF MULTIPLE-CCD DISPLACEMENT TRANSDUCERS IN THE ROAD PROFILING MEASUREMENT
多路CCD位移传感器用于路面纵断面检测研究

A road profilometer system using multiple-CCD displacement transducers is proposed in this paper.The principle of measurement is described.The data processing method and test results are given.The measurement speed is up to 60km/h with a resolution of 0.5mm and a maximum working range of ?120mm.It is proved that using this system to measure the road profiling is practically feasible.
