The invention discloses an intelligent road surface detection system and method based on three-dimensional laser scanning, and relates to the technical field of road surface detection, and three groups of algorithm units are matched with one another to jointly form a core architecture of the intelligent road surface detection system based on three-dimensional laser scanning. According to three-dimensional data of a to-be-detected road surface provided by a three-dimensional laser scanning technology, the flatness of the to-be-detected road surface and the speed degree of gradient change of the road surface are comprehensively considered, a comprehensive quality index PQi of the detected road surface is obtained through calculation, the comprehensive quality index PQi is compared with a warning threshold Y1 and a danger threshold Y2, and the warning threshold Y1 and the danger threshold Y2 are compared. According to the method, the transportation market management department can be reminded to take corresponding maintenance measures at the first time when the problems of large deformation, cracks or pits and the like in the road are detected, and personnel of the road transportation management department can quickly know the quality condition of the road surface through a real-time feedback mechanism, so that timely repair or maintenance decisions are made, and the maintenance efficiency is improved. And a scientific basis is provided for detection, repair and maintenance of the pavement.

    本发明公开了一种基于三维激光扫描的路面智能检测系统及方法,涉及路面检测技术领域,通过三组算法单元的相互配合,共同构成了基于三维激光扫描的路面智能检测系统的核心架构,通过三维激光扫描技术提供的待检测路面的三维数据,综合考虑待检测路面的平整度以及路面坡度变化的快慢程度,并计算得到的检测路面的综合质量指数PQi,将综合质量指数PQi与警戒阈值Y1和危险阈值Y2相比较,能够在检测出道路中出现了较大的变形、裂缝或坑洼等问题时,第一时间提醒运输市场管理部门采取相应的维护措施,实时的反馈机制使得道路运输管理部门的人员能够迅速了解路面的质量状况,从而做出及时的维修或保养决策,为路面的检测、维修和保养提供了科学依据。
