Paper Abstract

Pavement roughness is an important index to reflect the quality of pavement. To improve the efficiency of pavement roughness measurement, a novel pavement roughness measurement system based on structured light vision inspection is proposed in this paper. By describing the principle of structured light inspection and measurement system design, it is stressed that the proposed system can be used to acquire a continuous longitudinal profile of pavement and International Roughness Index by using the structured light illumination and CCD. Some experiments are performed to test orientation precision and performance of the system. The experimental results show that the system has some pros such as high orientation precision, good stability and low cost.
