Virtual camera for the sampling of an increased reality system on the semi-transparent display

Abstract : We present a novel extrinsic calibration method for optical see-through systems. It is primarily aimed at tablet-like systems with a semi-transparent screen, a user-tracking device and a device dedicated to the localization of the system in the environment but easily generalizable to any optical see-through setup. The proposed algorithm estimates the relative poses of those three component based on the user indicating the projections onto the screen of several reference points chosen on a known object. A convex estimation is computed through the resectioning of virtual cameras and used to initialize a global bundle adjustment. Both synthetic and real experiments show the viability of our approach.
