In this paper, a measurement system for rapid detection of longitudinal section of road surface by using multi-way charge-coupled device (CCD) displacement sensor is presented. The measurement principle is introduced and the data processing method and experimental results are given. The designed system speed is up to 60 km / h , The pavement height resolution is 0.5mm and the detection range is ± 120mm.The experiment proves that this system is feasible for the rapid detection of pavement profile.
