利用车载LiDAR的城市道路地理实体构建与应用
Construction and Application of Urban Road Geographical Entity Based on Vehicle-borne LiDAR
摘要
Abstract
In this paper,we designed a technology route of urban road basic geographical entity construction based on vehicle-borne LiDAR.Based on the point cloud and image data obtained by the mobile measuring vehicle,we obtained the basic geographical entity data of urban roads with high accuracy through the steps of metadata collection,attribute information collection,road entity construction and semantic processing on the basis of source data processing,which could provide a new technical path for the collection and update of basic geo-entity data in the new ba-sic surveying and mapping construction.Compared with the method of converting basic geographical entities by topographic map elements,this method can not only obtain road basic geographical entity in both 2D and 3D expression forms,but also improve the spatial accuracy and preci-sion of road basic geographical entity data.Through the production practice of road geographical entities in an experimental area of Wuhan,we found that the method proposed in this paper was feasible and effective,and the constructed road geographical entities had been gradually applied in the fields of new basic surveying and mapping,municipal road survey,road traffic simulation and so on.关键词
