Abstract
Embodiments of the present application provide a calibration method and device for dental implant navigation surgery, and a tracking method and device for dental implant navigation surgery. The calibration method comprises: () obtaining a position of a scanning area () relative to a second visual marker () based on a spatial position of a first visual marker () disposed on a scanning device (), a spatial position of the second visual marker () disposed on a surgical area (), and a scanning position of the scanning area () obtained by scanning with the scanning device (); and () registering the position of the scanning area () relative to the second visual marker () with a three-dimensional scene to obtain a transformation matrix, and applying the transformation matrix to the tracking of a surgical instrument. Therefore, the position change of a surgical instrument may be reflected in real time in the three-dimensional scene without implanting a marker point into the body of a patient, even if the patient's head moves during the surgery, thereby accurately tracking the surgical instrument in real time.
