Looks similar to ARToolKit (Score 1)

The marker looks very similar to those used in the Open Source ARToolKit - http://www.equator.ecs.soton.ac.uk/projects/artool kit/ - it uses known-size 2D barcodes to get the 3D transform of the camera relative to the position of the marker. Would probably be straightforward to extend the ARToolKit to be able to do this.
