Java中的Trilateration示例 [英] Trilateration example in java

问题描述

我目前正在开发一个利用RSSI根据信号强度确定位置的程序.有人知道三边测量的Java示例在哪里吗?我在网上找不到任何东西.

I am currently working on a program that utilizes RSSI to determine location based on signal strength. Does anybody know where a working java example is of trilateration? I couldn't find any online.

程序基本上需要输入3个距离，这是从RSSI得出的距离，然后是这三个点的纬度和经度，然后使用二维三边测量确定用户的位置(我忽略了每个信标).

The program will basically need to take in 3 distances, which are the distances derived from the RSSI's and then the latitude and longitude of the three points and then determine the user's location using 2 dimensional trilateration (I'm ignoring the height of each beacon for now).

我在这里看到了一个Python，但是我对Python的了解并不足够.

I saw a Python one on here, but I don't know Python well enough to understand it.

For future reference for anybody with the same problem.

我只是使用了Girish提供的链接. http://code.google.com/p/talking-points-3/source/browse/trunk/WifiPosition/src/TalkingPoint/thejoo/Trilateration.java?r=109

但是请注意，您必须考虑何时坐标是共面的，因为代码中没有考虑这一点.

but be aware you have to account for when coordinates are coplanar as this isn't accounted for in the code.
