Abstract

The embodiment of the invention discloses a bone saw calibration method and system in surgical navigation, and the method comprises the steps: fixing the coordinates of a saw blade tip point of a bone saw at a certain point in space, enabling the bone saw to rotate around the saw blade tip point, collecting N frames of surgical instrument calibration images in the process of rotating the bone saw, according to the collected N frames of surgical instrument calibration images, calculating a three-dimensional coordinate PNTip of the saw blade tip point under the bone saw coordinate system by adopting a conjugate gradient algorithm based on a maximum correlation entropy criterion. The conjugate gradient algorithm and the correlation entropy are combined, the conjugate gradient algorithm has the advantage of being high in convergence speed, the correlation entropy can restrain impulse noise, and therefore the calibration method has the advantages of being high in convergence speed and high in calibration precision.
