Precision Landing a Drone on an Aruco Array

Precision landing a drone via openCV and a camera on a single aruco marker can work, but it does not provide a robust range of altitudes the marker can be detected from. A huge aruco that is visible from 20 yards in the air will not be able to be tracked from 3 feet. Conversely, a small marker that is great for tracking at 3 feet will not be easily found from 20 yards. Aruco arrays combine the best features from large and small arucos, without any of the cons. Simply use a larger marker to unlock higher altitudes of detection, and a smaller marker for tracking once the drone gets closer to the ground. -------------------------------------------------------------------------------------------------------------- Link to the drone delivery course that not one... not two... but THREE drone delivery companies have taken! -- ------- ------------ https://dojofordrones.com/drone-deliv... ------------ ------- --
