激光点云建模在公路资产管理中的应用

Application of Laser Point Cloud Modeling in Road Asset Management

为了有效解决既有高速公路资产管理困难,无法实现构件级别的实时管理养护,现采用激光点云方式对既有运营高速公路进行路面激光扫描,结合点云信息对道路构件进行单体化建模,建立统一标准体系下的资产管理系统。本次试验以都汶高速公路都江堰至映秀段18 km为示范段,叠加实景模型还原道路场景信息,对单体化模型进行规范的分类编码,对多源异构数据进行分级分类统一组织管理,同时利用空间动态渲染机制,构建资产管理信息平台,为四川交通一张图计划进行探索分析。

In order to effectively solve the difficulties of asset management of the existing expressway that cannot realize real-time management and maintenance at component level, laser point cloud method is adopted to carry out laser scanning on the pavement of the existing in-service expressway.The point cloud information is combined to carry out monomer modeling on the road components, and an asset management system under a unified standard system is established.In this test, the 18-kilometer section from Dujiangyan to Yingxiu of the Dujiangyan-Wenchuan Expressway is used as the demonstration section.The road scene information is restored by superimposing the real scene model, standardized classification and coding of singulated models are conducted, and multi-source heterogeneous data are categorized and managed, and at the same time, by means of the spatial dynamic rendering mechanism, an asset management information platform is constructed so as to explore and analyze the One Map Plan of the Sichuan Transportation.
