I’ve pointed out a few resources to aid in creating augmented reality apps such as the free Vuforia library that provides a nice set of features such as easy marker detection and text recognition.
Here’s an in-depth tutorial from Paul Scholtz that goes through step-by-step the creation of a simple augmented reality game that uses OpenCV for marker tracking.
Some of the topics in the tutorial include:
– How to integrate OpenCV into your project
– Capturing a video stream
– Setting up the basic game controls and effects
– Detecting a marker
– Tweaking the marker tracking
A nice guide for those interest in learning the basics of creating an augmented reality app with OpenCV.
