Fast calibration for augmented reality

Fast calibration for augmented reality
Augmented Reality overlays computer generated images over the real world. To correctly depict spatial relations between real and virtual objects, these images have to be generated using transformations which correctly project a point in virtual space onto its corresponding point in the real world. This requires precise knowledge of the viewing projection of the head-mounted display (HMD) and its position. Methods to calibrate the projection parameters of the virtual cameras to that of the HMD have been presented in previous work. Most of these methods are complicated or use special equipment for the calibration process. We present a simple and fast calibration scheme, which does not require additional instrumentation or complicated procedures. This allows us to calibrate HMDs for specific users. The calibration process is presented to the user as interactively guided initialization step, which enables even inexperienced users to adapt the calibration to their eye distance and head geo...
