问题描述

我有一个建筑图，它有这么多的房间。

i have one building map and it have so many rooms on it.

现在我想要 / strong>在该建筑图中，用户正在该建筑物中，如果用户想要导航到其他房间，我也想绘制方向。

如果有人知道请指导我正确的方式。

if anyone knows please guide me in right way.

推荐答案

室内导航（或者如果没有GPS信号可用，则导航）通常使用WLAN三角测量来完成。您需要扫描建筑物中的WLAN，以便为特定位置构建各种WLAN信号的场强图。在导航期间，地图用于确定给定读取WLAN信号的最可能位置。

Inhouse navigation (or navigation if no GPS signal is available) is often done using WLAN triangulation. You need to scan the WLANs in the building to build a map of field strength of the various WLAN signals for specific locations. During navigation the map is used to determine the most likely position for a given reading of WLAN signals.

例如。 Google正在开展内部导航服务，还有一些公司提供室内导航解决方案。

E.g. Google is working on an inhouse navigation service and there are some companies offering inhouse navigation solutions.
