AR-Tag-Detection

The objective is to detect a custom AR tag that can be used to obtain a point of reference in the real world for augemented reality applications

Overview

• The project is divided into 3 parts
• In First part, the AR Tag is detected and it tag orientation and ID is decoded
• In the second part, a reference image is placed on the Tag such that it superimposes the tag in the whole video
• In the third part, a virtual cube is placed on top of the Tag in the whole video
• OpenCV methods such as find-contours, hough-transform, find-homography and warp-perspective have not been used, these methods have been implemented from scratch

Results

• AR Tag Corners Detected and ID Decoded: 0111 or 7

• Testudo Image superimposed on the detected AR Tag

• Virtual Cube placed on the detected AR Tag

Build dependencies
