A novel system for road surface monitoring using an inexpensive infrared laser sensor

摘要: In this study, an inexpensive depth sensor is used to identify defects in pavements. This depth sensor consists of an infrared projector and camera. An innovative approach is proposed to interpret the data acquired by this sensor. The proposed system in this study is a breakthrough achievement for autonomous cost-effective condition assessment of roads and transportation systems. Various road conditions including patching, cracks, and potholes can be robustly and autonomously assessed using the proposed approach. Several field experiments have been carried out to evaluate the capabilities of this system. The field tests clearly demonstrate the superior features of the developed system in this study compared to conventional approaches for pavement evaluation.
