摘　　要：随着基于位置感知技术的实时定位系统深入发展和应用,其对可视化技术的要求越来越高。如何在主流架构模式下实现复杂室内外静、动态场景目标的二三维实时可视化是其首要任务之一。分析了实时定位可视化技术的特点,结合Web GIS和Web3D技术,设计并实现了一种基于B/S架构的实时定位二三维可视化框架。按照该框架构建了体育馆人员定位系统,结合定位实验中场景渲染和目标运动轨迹效果,对该框架进行了验证。实验结果表明,该框架具有良好的实时性、双向交互性和可扩展性。With in-depth development and application of location-aware technology based real-time locating system, its requirement on visualisation technology is getting growingly higher. It is one of its primary tasks that how to realise the 2D/3D real-time visualisation of complicated indoor and outdoor, static and dynamic scenes objects in mainstream architecture mode. In the paper we analyse the features about RTLS visualisation technology, and design and implement a B/S structure-based 2D/3D real-time locating visualisation system framework in combination with WebGIS and Web3D technology. According to the frame, a stadium personnel positioning system is built, the framework is validated in conjunction with the scene rendering system and target moving trajectory effects in locating experiment. Experimental results show that the framework has good real-time property, two-way interaction and scalability.
