1. A method comprising:

  • capturing multiple images of a planar object;

    selecting a new image as a new keyframe;

    calculating homographies between the new keyframe and each of a plurality of previous keyframes for the planar object that are spatially distributed;

    generating a graph structure using the new keyframe and each of the plurality of previous keyframes and the homographies between the new keyframe and each of the plurality of previous keyframes;

    using the graph structure to create a map of the planar object; and

    tracking the planar object based on the map and subsequently captured images.
