This dataset is composed of photos obtained by attaching multiple ArUco markers to the walls in the corner of a darkened room, projecting a video containing moving shadows and lighting patterns over the corner, and then recording the resulting scene from 6 different points of view, for a total of 8652 frames with a resolution of 800 x 600. For each image, the ground-truth labels of the markers are provided, tagged with a method based on the classic ArUco technique, and manually adding the positions and IDs of undetected markers.
