超过 3 个圆的三边测量
我正在尝试进行三个标准点的三材料,我将它们都视为一个圆圈的中心。我完全遵循提供的指令,提供的指令在本教程中a>以及 in Wikipedia in Wikipedia 。我只是想知道,如果有4个圆圈,我是否必须通过4选择3
方法?或者有什么替代方案吗?
任何形式的帮助将不胜感激!
I am trying to do the trilateration where I have exactly 4 beacon points and I considered each of them as the center of a circle. I have entirely followed the instruction provided in this tutorial and also in in wikipedia. I was just wondering, in case of 4 circles do I have to go through 4 Chosen 3
method? Or is there any alternative?
Any sort of help will be appreciated!

您可以按照维基百科文章推导 3 个圆的公式相同的方式推导 4 个圆的公式。
文章中的解释是:通过制定四个球面的方程,然后求解四个未知数 w、x、y 和 z 的四个方程来找到解。
实际上,通过 4 个球体,您可以确定高度以及纬度和经度。
恐怕数学超出了我的能力,但也许其他人可以提供帮助。
You can derive the formulas for 4 circles in the same manner that the Wikipedia article derived the formulas for 3 circles.
From the article, paraphrased: The solution is found by formulating the equations for the four sphere surfaces and then solving the four equations for the four unknowns, w, x, y, and z.
Actually, with 4 spheres, you can determine altitude, as well as latitude and longitude.
I'm afraid that the math is beyond me, but maybe someone else can help.
