数字模型库

创新中心的数字模型库包含中国道路元素模型、中国典型路口模型、车辆及交通参与者模型以及场景环境模型4大类。① 中国道路元素模型是参考国家标准法规及公开道路图片信息搭建，主要包括车道线、（警告、指示、禁令、指路等）标识牌、路面文字、抄袭车道、公交车道、地方化标识、定制化交通设施、路侧单元等，覆盖了法规中超过90%的道路元素。② 中国典型路口模型是通过百度地图、高德地图等相关公开信息提取路口元素并还原构建，支持中国道路的拓扑结构。目前已覆盖隧道、环岛、T型路口、执行道路、弯道、匝道 、非结构化道路等21类城市道路路口结构，以及10余类乡村道路路口结构模型 。③ 车辆及交通参与者模型：依据公开信息还原路面上的交通车辆。支持车辆本身的动态行为的动画深度开发。车辆类型包括具有中国特色的机动车、非机动车，如商用车、乘用车、工程车、特种车、两轮车、三轮车等，已完成市面常见的交通车辆100余个。④ 场景环境模型： 根据需求定制化开发道路周边环境设施，如封闭园区、高速收费站、停车场、矿区等的建筑设施。支持工程机械类动作的动画深度开发。

The digital model library of the Innovation Center includes four major categories: Chinese road element models, Chinese typical intersection models, vehicle and traffic participant models, and scene environment models. 1. Chinese road element models: Built with reference to national standards, regulations and public road image data, they mainly cover lane lines, traffic signs (warning, indication, prohibition, direction signs, etc.), road surface text, passing lanes, bus lanes, localized signs, customized traffic facilities, roadside units, etc., covering more than 90% of the road elements specified in relevant regulations. 2. Chinese typical intersection models: Developed by extracting and reconstructing intersection elements from public information sources such as Baidu Maps and Amap, these models support the topological structure of Chinese road networks. Currently, they cover 21 types of urban road intersection structures including tunnels, roundabouts, T-junctions, straight roads, curves, ramps, unstructured roads, etc., as well as more than 10 types of rural road intersection models. 3. Vehicle and traffic participant models: These models restore traffic vehicles on roads based on public information, and support in-depth animation development of the dynamic behaviors of the vehicles themselves. The supported vehicle types include Chinese-style motor vehicles and non-motor vehicles, such as commercial vehicles, passenger cars, engineering vehicles, special vehicles, two-wheelers, three-wheelers, etc., with over 100 common traffic vehicle models on the domestic market completed. 4. Scene environment models: These models customize and develop road surrounding environmental facilities as required, including architectural facilities in closed parks, expressway toll stations, parking lots, mining areas, etc., and support in-depth animation development of actions related to construction machinery.
