推荐答案

冒着明显的危险:

1)列出您要达到的目标，例如(在著名建筑物上显示标签)
2)分解实现目标所需的步骤(例如，存储要显示的位置和信息，提供从数据库获取信息的服务，编写应用程序以通过实时摄像机图像显示信息).


您一直重复执行第2步，直到您有足够小的单位可以进行Google/入门操作为止.
就个人而言，我将从应用程序端开始:只需尝试获取一个硬编码标签即可在硬编码位置上显示.这可能是最困难的任务，因为您要根据与您要标记的对象不同的位置将空间坐标投影到二维图像(相机图像)上.以硬编码方式完成此操作后，您可能会看到需要什么数据来更清楚地存储位置，因为您可能需要的数据比物理坐标还要多.

At the risk of stating the obvious:

1) Write a list of aims you want to achieve, e.g. (display tags on famous buildings)
2) Break down the steps needed to fullfill your aims (e.g. Store location and information to display, provide a service to get the information from the DB, write an application to display the information over a live camera image).


You keep repeating step 2 until you have small enough units to work on to be able to google/get started.

Personally, I''d start at the application end: just try and get a hard coded label to display on a hard-coded position. This is likely to be the hardest task to sort as you are projecting a spacial co-ordinate onto a 2-D image (the camera image) based on a location which isn''t the same as the one you are projecting you tag onto. When you have done this in a hard-coded way, you can see what data you need to store a position more clearly as you might need more than the physical co-ordinates.
