基于真三维模型的室内定位系统设计

为了解决全球定位系统在大型室内场合无法给出精确定位的问题,设计了一种安卓平台下基于真三维模型的室内定位系统。基于百度地图SDK(software development kit)开发一款室外定位的电子地图软件,用于获取室内场景所在位置,再结合Unity3D游戏引擎将根据室内场景制作比例为1的模型制成可在安卓设备上运行的软件,通过虚拟现实技术及空间位置服务,实现室内定位功能。结果表明:系统具有的功能基本满足用户室内外定位需求,且系统具有定位方法直观、功能服务全面及系统搭建简单等特点,适用于一些大型的室内外公共场合,如商场、机场、博物馆等。

Indoor Positioning System Design Based on True 3d Model

In order to solve the problem that global positioning system cannot give accurate positioning in large indoor occasions, an indoor positioning system based on true 3d model under android platform was designed. Based on the Baidu map SDK, an outdoor positioning electronic map software was developed to obtain the location of the indoor scene. Combined with the Unity3D software, the model based on the indoor scene was made into a app that can run on the Android device. Through virtual reality technology and spatial location service, indoor positioning function was realized. The results show that the system has the functions to meet the indoor and outdoor positioning requirements of the user, and the system has the characteristics of intuitive positioning method, comprehensive functional service and simple system construction. It is suitable for some large indoor and outdoor public places, such as shopping malls, airports and museums.
