position sensor

For augmented reality (AR)-guided endoscopic surgery, patient–image registration and hand–eye calibration are essential steps and they have been separately performed so far with accumulating errors. In the proposed method, the two separate steps are integrated in a single step with minimized errors under the on-site AR condition. The AR superimposing accuracy can increase due to the reduced computational complexity of transformation processes and the compensated tracking errors of the position sensor… read more
