如何开始增强现实？ [英] How to begin with augmented reality?

问题描述

我现在是计算机科学的本科生，我将进入明年的最后一年。增强现实是我觉得是一个非常有趣的话题，但我不知道从哪里开始学习它。

I'm currently an undergrad in computer science and I'll be entering my final year next year. Augmented reality is something I find to be a really interesting topic, but I have no idea where to start learning about it.

您从哪里开始了解这个主题和可用的图书馆？

Where do you start learning about this topic and what libraries are available?

推荐答案

作为一个相当受欢迎的流行语，增强现实可以用一些不同的算法构建，可以单独学习。通常它包括：

Being a quite popular buzz word, augmented reality can be build with some distinct algorithms which can be learnt separately. Usually it covers:

• 平面对象检测（可以是标记或以前训练的对象）。
  SURF / SIFT / FAST描述符，RANSAC用于单应性矩阵计算


• 将训练的对象存储在DB（KD-树）中


• 估计


• 使用自定义对象（OpenGL）增强3D模型

• planar object detection (can be a marker or previously trained object). SURF/SIFT/FAST descriptors, RANSAC for homography matrix calculation
• store trained objects in DB (KD-trees)
• camera position estimation
• augmenting 3D model with custom objects (OpenGL)

要深入了解此主题将推荐此步骤：

To dive into this subject I would recommend this steps:

• 所有这些都已在OpevCV中实现，您可以开始使用其示例。


• 要了解引擎盖下发生的情况，可能是关于此主题的最好的书：
  计算机视觉中的多视图几何 http://www.robots.ox.ac.uk/~vgg/hzbook/ 。


• 如果您要在手机上玩AR，请查看科学实验室的作品
  ，比如 http://mi.eng.cam.ac.uk/~sjt59/hips.html （FAST）和 http://www.robots.ox.ac.uk/~gk/PTAM/ （PTAM）。

• All of this is already implemented in OpevCV, you can start playing with its examples.
• To understand what's happening under the hood, take probably the best book on this topic: "Multiple View Geometry in Computer Vision" http://www.robots.ox.ac.uk/~vgg/hzbook/ .
• If you are going to play with AR on mobile phones take a look on works of scientific labs like http://mi.eng.cam.ac.uk/~sjt59/hips.html (FAST) and http://www.robots.ox.ac.uk/~gk/PTAM/ (PTAM).
