摘　　要：由于智慧高速上交通事件检测设施的布设较传统做法更密集,其布设需考虑高速公路的平纵线形、公路沿线布设的交通标志牌、上跨桥等对检测摄像机监控范围的影响。通过建立反映高速公路设计和其沿线设施布置的三维模型和摄像机在三维空间中的有效监控范围模型,在三维场景下分析交通事件视频检测摄像机的布设问题,以期为设计提供指导。Traffic incident detection,as an important item of all-factor perception on smart highways,has been widely used in recent years.Since the placement of traffic incident detection facilities on smart highways is denser than that on traditional highways,their placement needs to consider the impact that the highway's alignment and profile,traffic signs along the highway and overpass bridges have on the monitoring range of inspection cameras.This paper adopted the method of 3D modeling to establish a federated model that reflects the highway's design,the layout of various kinds of facilities along it,and the camera's effective monitoring range model in 3D space.Then the placement of video traffic incident detectors on highways in 3D scenes was discussed.The guidance for designing the layout of video traffic incident detectors on highways is given.
