Abstract
A surgery assistance system including a rigid endoscope having a position-orientation detection marker, 3-dimensional (3D) shape measurement device for obtaining data corresponding to a 3D surface of a patient and data corresponding to a 3D surface of the position-orientation detection marker, and computation unit for aligning pre-stored tomographical data of the patient and the data corresponding to the 3D surface of the patient, computing an optical axis of the rigid endoscope on the basis of the data corresponding to the 3D surface of the position-orientation detection marker and a pre-obtained 3D relative position relationship between an actual optical axis of the rigid endoscope and the position-orientation detection marker, for computing a tissue wall in the patient from the 3D tomographical data, and for computing an intersection of the tissue wall and the computed optical axis of the rigid endoscope.
