The XO-OLPC laptops measure distance between themselves using sound instead of radio waves.
Assume your 2 routers were 1,000 feet apart and you were standing between them. It only takes 0.0000005 seconds for the radio signal to go 500 feet. I don't think your computer's clock will be accurate enough to measure that.
I don't think ping time would be a reliable indicator of distance. If the routers are wireless there could be other factors that change the latency between them. Maybe during certain times of day there is more electromagnetic interference in the area which would affect the latency.
As for determining distance through the internet, this also would be impossible to determine through latency as you are passing through many routers which are not under your control. Some could have a substantial load on them which would cause more latency and increase the latency (or decrease) skewing the proportions.
I don't think there really is a way to find the position of a router in 3d space.
XO-OLPC 笔记本电脑有一个距离测量应用程序，可以告诉您两台 XO 笔记本电脑之间的距离，但我从未尝试过，所以这当然是可能的。
您还需要（准确地）测量基站之间的距离。
You would probably need access to lower level information from the radio in the WiFi system.
The XO-OLPC laptop had a distance-measuring application which would tell you the distance between two XO laptops, but I never was able to try it, so it's certainly possible.
You would also need to (accurately) measure the distance between your base stations.

XO-OLPC 笔记本电脑使用声音而不是无线电波来测量彼此之间的距离。
假设您的 2 个路由器相距 1,000 英尺，并且您站在它们之间。 无线电信号传播 500 英尺仅需 0.0000005 秒。 我认为你的计算机时钟不足以准确地测量它。

我不认为 ping 时间是距离的可靠指标。 如果路由器是无线的，则可能有其他因素会改变它们之间的延迟。 也许在一天中的某些时间，该区域的电磁干扰较多，这会影响延迟。
至于通过互联网确定距离，这也无法通过延迟来确定，因为您要经过许多不受您控制的路由器。 有些可能会承受很大的负载，这会导致更多的延迟并增加（或减少）延迟，从而扭曲比例。
我认为确实没有办法找到路由器在 3d 空间中的位置。

您可能需要通过 WiFi 系统中的无线电访问较低级别的信息。
