增强现实运动
大家好，我遇到了与增强现实相关的问题，请帮助
问题
我需要在相机覆盖层上显示任何运动物体的标签，例如
我有 4 个物体，比如四个方向的四个房子，即南北东西向，当我向北看时，我应该能够看到该房子的唯一一个标签，
该标签上会有一些信息，比如房子名称，所以
- 当我向南方向移动时该怎么做，北标签应该开始移到一边，南标签应该开始出现在屏幕上
我仍然完成的解决方案
当我看到北时，我能够显示所有四个带有信息的标签（但我只能显示一个）
Hey guys i am in a problem related to augmented reality please help
PROBLEM
I need to show the label on camera overlay for any object with movement for example
i have 4 object say four house in four direction i.e. south north east west and when i see to north i should be able to see the only single label for that house
on that label there will be some information say house name so how to do it

要移动对象，您需要将屏幕的像素数除以视野角度之间的像素数，以获得每度的像素数，并将其乘以对象距航向的偏移量。
这是很简单的事情，所以我编写了一个示例项目。它不是一个图书馆，重点是告诉你从哪里开始。从那里你应该检查 github 上的现有库（基本上是arkit）并提出更具体的问题。
To move the object around you need to divide the number of pixels of the screen between the degrees of the field view to get pixels per degree, and multiply that by the offset of the object from your heading.
This is easy stuff so I wrote an example project. It is not a library, the point is to show you where to start. From there you should check existing libraries on github (arkit basically) and make more specific questions.

我发现它非常有用。我试图实现一个演示，有点像这个 iPhone 应用程序： http://www.acrossair.com/ acrossair_app_augmented_reality_browser_for_iPhone_3GS.htm
这是您需要的吗？

I found it very useful. I was trying to implement a demo, sort of like this iPhone app: http://www.acrossair.com/acrossair_app_augmented_reality_browser_for_iPhone_3GS.htm
Is it what you need?
