This video shows ArUco library in action detecting AR Boards
Benefits of using AR Boards
Detecting a single marker might fail for different reasons such as poor lightning conditions, fast camera movement, occlusions, etc. To overcome that problem, ArUco allows the use of boards. An Augmented Reality board is a marker composed by several markers arranged in a grid. Boards present two main advantages. First, since there have more than one markers, it is less likely to lose them all at the same time. Second, the more markers are detected, the more points are available for computing the camera extrinsics. As a consecuence, the accuracy obtained increases.
