In this article authors present a new calibration method to increase the precision of the position for a Hololens. Using external system combined with embedded SLAM and a “hand‐eye” based approach, it could be possible to lowered uncertainty on Virtual/Real position close to 3 mm.
Augmented reality (AR) allows the surgeon to represent holographic patient‐specific anatomical information and surgical instruments on the physical world. To correctly superimpose virtual and physical objects, a hand‐eye calibration method for mapping the virtual and physical spaces was proposed.
