增强现实浏览器如何跟踪您准确的位置以覆盖相关信息？(How do Augmented reality browsers track you accurate location to overlay relevant information?)

AR浏览器包括可用于Iphone和Android智能手机的wikitude，Layar等。

当您将相机指向地标时，它们会自动覆盖之前可用信息（例如，门上的餐馆名称）

如果某些GPS的状态精度为~10 m，那么如何才能准确完成？

我的意思是，如果他们跟踪手机的位置以显示地理上准确的信息，甚至2-3米的差异可能会造成严重破坏。

AR browsers include those like wikitude, Layar etc that are available for Iphone and Android smartphones .

When you point your camera to a landmark they automatically overlay previously available information for a location over it (e.g. name of a restaurant over its door)

If the accuracy of GPS as states by some is ~ 10 m , how can this be done accurately ?

I mean if they track the location of your phone to display geographically accurate information , a difference of even 2-3 m can cause havoc.

您可以自行查看mixare的代码，这是一个在自由软件许可证（GPLv3）下发布的增强现实浏览器。 对于Android和iPhone，源代码在github上都可用。

回答你的问题：有错误，主要是因为罗盘读数（数字罗盘是不可靠的，因为它们拾取各种噪音）。 有用的是你通常会寻找相当大的物体（建筑物等），因此错误不是最终用户可见的，但它仍然在那里，相信我:)

you can check by yourself in the code of mixare, which is an augmented reality browser released under a free software license (GPLv3). The source code is available on github both for android and iPhone.

To answer your question: there are errors, mostly because of the compass readings (digital compasses are unreliable because they pick up every kind of noise). What helps is that you are usually looking to objects that are quite big (buildings etc.) hence the error is not THAT visible to the end user, but it's still there, trust me :)
