Image-guided surgery is a key positioning technique in cranial neurosurgery, which is beneficial to reduce the volume of lesion and improve the positioning accuracy of the lesion. At present, most of the research on image guided surgery focuses on a particular part of calibration. This paper proposes a brain puncture surgery method based on stereo vision. Through the calibration of surgical instrument and head model, the instrument tip and head lesion point are unified into the global frame to realize the real-time navigation of brain puncture surgery. Finally, the feasibility and accuracy of the method are verified by experiments.
