                An aruco marker is a fiducial marker that is placed on the object or scene being imaged. 
                It is a binary square with black background and boundaries and a white generated pattern within it that uniquely identifies it.
                The black boundary helps making their detection easier. They can be generated in a variety of sizes.
                The idea is that you print these markers and put them in the real world.
                You can photograph the real world and detect these markers uniquely.
