AR-Homography

AR Tag Detection, Decoding, Tracking, and Superimposing image and cube on the tag

Description

This project inolves detection of AR TAG, decoding, tracking and placing an image over the top of the tag.

Folder contents:

1) myUtils.py: file having all major functionlity - warping, tag decoding, homography, calculating projection matrix and drawing cube
2) part1a.py: For detecting AR Tag using FFT and IFFT
3) part1b.py: For decoding the AR Tag
4) part2a.py: For superimposing turtle on top of AR Tag
5) part2b.py: For placing a 3D cube on top of AR Tag
6) Four video files
7) test.png: Turtle image
8) AR_REF.png: Reference tag to be used in 1b
9) frame.jpg: One frame from Tag1.mp4 to be used in 1a
10) Readme.md: this file
11) ENPM673_Project1_Report.pdf: Project report

Steps to run:

1) Please make sure all the above video and image files are in the same location as python files
2) Run as:
	python3 part1a.py
	python3 part1b.py
	python3 part2a.py -> Tag video to be selected during runtime
	python3 part2b.py -> Tag video to be selected during runtime

Outputs from run:
