车载移动测量系统在路面平整度评价中的应用
|
摘要
路面平整度关系到车辆行车的安全性、舒适度以及道路的使用寿命,是评定道路路面质量的主要技术指标之一。传统的分析方法大多数都是利用道路纵断面上离散点的高程信息来分析评价道路平整度,不过却存在着人力、物力消耗大,分析结果精度达不到标准的缺点。车载移动测量设备外业采集的激光点云数据包含了丰富的路面高程信息,完全符合路面平整度分析对于数据的要求。本文从激光点云数据中提取出道路纵断面上最大深度信息,进行路面平整度分析,取得了满意的效果。
Road roughness is related to the safety, comfort and service life of the vehicle. And it is one of the main technical indexes to evaluate the road surface quality.Most of the traditional analysis methods use the elevation information of the discrete points on the road section to analyze the road roughness, but there is a large consumption of human and material resources, and the accuracy of the analysis results can not reach the standard.The laser point cloud data collected from the vehicle mobile measurement equipment contains rich pavement elevation information, which is fully in line with the requirements of pavement roughness analysis for data.In this paper, the maximum depth information of road profile is extracted from the laser point cloud data, and the pavement roughness is analyzed.Satisfactory results have been achieved.
