Three-dimensional real-time positioning compensation method for surgery

Abstract

A three-dimensional real-time positioning compensation method for surgery includes: obtaining an initial posture of each of a plurality of marking devices in a surgical image in a world coordinate system; performing brightness normalization on the surgical image to generate a normalized image; respectively generating a plurality of texture images with different resolutions for all marks of the plurality of marking devices, and using the texture image having the closest resolution as a standard image; selecting at least N additional sampling points from the standard image, and obtaining a corresponding reference point in the normalized image; and obtaining an optimization point with a minimum brightness error from each reference point, respectively performing a calculation to obtain an error; and correcting the initial posture according to the errors to generate a compensation posture.
