android - 关于室内定位的问题

Question

室内定位是否需要专业测绘人员采集室内数据上传到SDK服务商（比如高德地图，百度地图）的服务器后才能进行室内定位？比如我要定位到哪一层楼的哪一个房间

Answer 1

There are methods for locating people, including mobile phone base station positioning, satellite positioning and other methods. However, most of these positioning are based on plane longitude and latitude positioning. At most, the approximate altitude can be known, but the accurate height cannot be known.

Floor indoor positioning systems are currently being developed and applied. This kind of positioning is decimeter-level positioning. It can accurately know which floor a person is on and where in the room it is. However, it is not mature enough, has a relatively high cost, and is rarely used.

Answer 2

I did indoor positioning two years ago. The mainstream technologies available at that time were Wifi hotspots and Bluetooth. The principles of outdoor positioning are completely different, and there are currently no mature products. It is also very troublesome to use. First, the area to be located must have enough hot spots. Secondly, before use, the area must be scanned to obtain fingerprint data before use.
