Aruco tutorial

Setup instructions:

1. Create a new conda environment w/ python 3.8 (optional but highly recommended)

conda create -n aruco_tutorial python=3.8
conda activate aruco_tutorial

2. Install requirements pip install -r requirements.txt
3. Run camera_calibration.py. This will calibrate your camera with the images in the images/ folder. Those images are obviously going to be wrong, since I took them using my webcam and not whatever camera you're using, so your pose estimation will probably be off unless take your own pictures.
4. Run aruco_pose_estimation.py. This will display the pose of the aruco marker if it is within the camera frame, and will also display the orientation axes.
