摘要
为同时提供到校与校外服务,让师生宏观了解校园布局及相关资源分布,设计高校三维定位AR导览系统,系统采用3DsMax软件制作三维模型,用Vuforia SDK识别目标地点平面图像,并通过显示Intent、ListView、百度地图SDK及Shared SDK实现模式切换、区域列表、基本地图定位与分享等交互功能。经测试,系统在功能上基本完成需求,可增强渲染校外与校内场景中的地点目标,达到预期的虚实融合的效果;同时,定位误差全部低于0.6 m,最小误差为0.2 m,所用时间为13 s,性能也可满足师生基本需求,有良好的师生用户体验。
In order to provide campus service and off-campus service simultaneously, and help teachers and students to understand campus layout and resource distribution macroscopically, the paper designs an universities three-dimensional positioning AR navigation system. It uses 3 DsMax, Vuforia SDK, Intent, ListView and other tools to make 3 D model, identify target location’s flat image, switch mode and other functions. The tests show that system can meet function needs, it can enhance the rendering of scene regional goals, and achieves virtual-real fusion effect. At the same time, the system’s position error are all less than 0.6 m, minimum error is 0.2 m, its time is 13 s, the performance can also meet students and teachers’ basic needs, the user experience is good.
