摘要随着城市化水平的快速发展,城市路网不断延伸,道路检测需求急增,传统的道路检测方式存在着人工成本高、效率低、检测结果不够准确等缺点,现代化道路检测方式正在逐渐取代传统的检测方式。为评价路面使用性能,维护道路安全,提高道路检测效率,本文提出使用车载激光雷达系统进行路面检测,车载激光雷达系统可以快速获取高精度路面点云,将车载路面点云数据进行去噪、处理,分别从路面平整度、裂缝、车辙及构造深度检测方面,提出不同检测方法。依据检测结果,车载激光雷达系统检测路面具有一定的可行性,对于提高驾驶安全、保障公共交通运输、节约维护成本等方面具有重要意义。 With the rapid development of urbanization level,the urban road network continues to extend,the demand for road inspection is increasing rapidly,the traditional road inspection method has the shortcomings of high labor cost,low efficiency,and less accurate test results,modern road inspection methods are gradually replacing the traditional inspection methods.In order to evaluate the pavement performance,maintain road safety and improve the efficiency of road inspection,this paper proposes the use of vehicle-mounted light detection and ranging(LiDAR)system for pavement inspection.The vehicle-mounted LiDAR system can quickly obtain high-precision pavement point clouds,denoise and process the vehicle-mounted pavement point cloud data,and propose different inspection methods in terms of pavement flatness,cracks,rutting and structural depth detection,respectively.Based on the test results,the vehicle-mounted LiDAR system has certain feasibility in detecting pavements,which is important for improving driving safety,protecting public transportation and saving maintenance costs.
