In this work we present a new distributed technique to geometrically calibrate multiple projectors on a fiducial free arbitrary surface using multiple casually aligned cameras where every point of the surface is seen by at least one camera. Using a multi-step method that uses binary blob patterns, we estimate robustly the display’s 3D surface geometry, the cameras’ extrinsic parameters, and the intrinsic and extrinsic parameters of the multiple projectors.
