基于车载激光扫描系统的道路平整度研究

Research on Road Roughness Based on Vehicle Laser Scanning System

摘要: 传统测量公路路面平整度的方法是三米直尺法，但此方法测量效率低、误差大、受人为干扰因素大，越来越不能够满足现代社会对于公路质量检测和公路养护的需求。随着激光雷达的快速发展，非接触式检测采集路面、建筑等目标物体的表面信息的仪器也成为了当前社会研究的热点，车载激光雷达扫描系统基于其非接触性、高效率、高精度、的特点，成为了快速测量路面平整度的新方法。

Abstract: The traditional method of measuring road surface roughness is the three-meter ruler method, but this method has low measurement efficiency, large error and large human interference factors, which is increasingly unable to meet the needs of modern society for road quality inspection and road maintenance. With the rapid development of laser radar, the instrument of non-contact de-tection and acquisition of surface information of target objects such as pavement and building has become a hot topic in current social research. Based on its non-contact, high efficiency, high preci-sion and other characteristics, the vehicle-borne laser radar scanning system has become a new method for rapid measurement of pavement flatness.
