复杂交通枢纽实景三维一张图可视化智能管理关键技术

Key Technology of Intelligent Management of Complex Transportation Hubs with Realistic 3D One-map Visualization

针对现代化交通枢纽存在空间复杂、功能多样,人流物流密集等复杂性特点导致的局域出行和安全管理困难等问题,综合分析场景数据、区域信息流、警务专题数据、政务管理数据及各业务需求单位的关系特点,研究了视觉语义增强的全域实景三维建模技术、语义对象级融合的混合定位技术以及多终端协同警民联动应用技术的关键技术,设计开发了复杂交通枢纽实景三维一张图可视化智能管理系统,包括大屏端实景漫游、一主六辅全景资源可视化、警力在线、警情联动、商户一户一码、小程序全景增强室内导航,警务通/执法仪在线示警等功能模块,整合区域重点公共管理数据及横向部门数据,打通警务、政务以及民众等一体化联动应用,支持警务全局综合指挥与局部精准决策和民众快进快出需求,以代表性复杂交通枢纽杭州东站和萧山机场为例进行了应用验证,结果表明技术平台能有效支撑路地警务融合样板,也丰富了城市大脑中的智慧安保与民众出行服务等应用。

Aiming at the problems of local travel and safety management caused by the complex characteristics of modern transportation hubs,such as spatial complexity,functional diversity and dense human and logistic flows,this paper comprehensively analyzes the scene data,regional information flow,police thematic data,government management data and the relationship characteristics of each business demand unit,and researches the visual semantic enhancement of the whole area realistic 3D modeling technology,semantic object-level fusion of hybrid positioning technology,and the key technologies of multi-terminal collaborative police and public linkage application technology,designed and developed a complex traffic hub realistic 3D one map visualization intelligent management system,including realistic roaming,online navigation,information query,resource visualization and other functional modules,integration of regional key public management data and horizontal departmental data,through the police,government and the public and other integrated linkage applications,to support the police overall comprehensive command and local.The application verification was carried out with the representative complex transportation hub Hangzhoudong railway station and Hangzhou international airport as examples,and the results show that the technology platform can effectively support the integration of road and land police prototypes,and also enrich the applications of smart security and public travel services in the city brain.
