基于AR的三维城市信息系统设计与实现

Design and Implementation of 3D Urban Information System Based on AR

针对目前的三维城市信息系统(3DUIS)是以2D的屏幕为载体,使得现有的城市空间信息得不到充分地表达和可视化的问题,提出了将增强现实技术应用于3DUIS的方案,改变3DUIS的载体,从2D屏幕视角载体转向3D视角载体,并提供了基于规则的快速三维城市场景建模和人机交互的设计思路,基于旧金山的基础二维地理数据以及微软增强现实设备Microsoft Holo Lens实现了AR-3DUIS应用程序。结果表明AR-3DUIS提供给用户更强、更真实的三维城市信息体验,以及更自然的UIS交互方式。

In view of the situation, 3 D UIS（Urban Information System） perspective carriers refer to mainly 2 D, the existing urban spatial information is not fully expressed and visualized. This paper proposed an approach of applying augmented reality technology to 3 D UIS. It changed the carrier of 3 D UIS, from the 2 D screen perspective carrier to 3 D perspective carrier, and provided a method of fast 3 D urban scene modeling based on rules and human computer interaction. Then, the AR-3 DUIS application was implemented based on the basic 2 D geographic data of San Francisco and the Microsoft augmented reality device Microsoft Holo Lens. It was demonstrated that AR-3 DUIS could provide users with a stronger and more realistic experience of 3 D urban information, and a more natural UIS interaction.
