Marker-based Augmented Reality on iPhone or iPad

In this article by Eugene Khvedchenya, the author of Mastering OpenCV with Practical Computer Vision Projects, introduces us to Augmented reality (AR), which is a live view of a real-world environment whose elements are augmented by computer-generated graphics.

In this article we will create an AR application for iPhone/iPad devices. From this article you'll learn more about markers. The full detection routine is explained. After reading this article you will be able to write your own marker detection algorithm and estimate the marker pose in 3D world with regards to camera pose.

In this article, we will cover the following topics:

• Creating an iOS project that uses OpenCV

• Application architecture

• Marker detection

• Marker identification

• Marker code recognition

• Placing a marker in 3D
