如何跟踪一个Android设备的建筑物的位置？ [英] How to track position of an Android device in a building?

问题描述

我想开发中，我需要知道我的设备的建筑物（的房间，里面的设备是目前）内的位置的应用程序。 GPS不能正常使用的建筑。有什么办法可以找到设备的建设持何立场？如果是的话怎么样？我可以使用位置或运动传感器的这些或组合用于此目的？

I want to develop an application in which I need to know the position of my device within a building (the room in which the device currently is). GPS is not working in the building. Is there any way to find the position of the device in building? If yes how? Can i use position or motion sensors or combination of these for this purpose?

推荐答案

有没有通用的解决方案。如果你可以（pferably $ P $的每间客房）将WiFi热点/中继器的建设中，你可以从三角WiFi信号强度的位置。但是，这是因为通过墙壁和地板不同的信号损失也并不简单。你需要调查建筑物，使信号强度地图提前，然后根据收到的信号，看看你的位置在地图上。

There is no general solution. In case you can place WiFi hotspots/repeaters in the building (preferably in every room), you can triangulate the position from the WiFi signal strengths. But that's also not straightforward, because of different signal losses through the walls and floors. You'll need to survey the building and make a signal strength map in advance and then, based on the signals you receive, look up your location on the map.

运动传感器也没有precise不够，指南针，如果你是一个钢结构建筑内，是不准确的，太。

Motion sensors are also not precise enough and compass, if you are inside a steel construction, is inaccurate, too.
