Abstract
The present invention relates to a method for acquiring the position of points for navigated surgery, the method being constituted to be executed by a computer and comprising the following steps:—acquiring, on the basis of detecting a first tracked device, first point position data for each of at least two points, wherein the first point position data comprise point position information describing the three-dimensional position of the point within a first co-ordinate system assigned to the first tracked device;—acquiring first co-ordinate transformation data for each of at least two points, wherein the first co-ordinate transformation data comprise co-ordinate transformation information describing a transformation of the three-dimensional position of the point from the first co-ordinate system to a second co-ordinate system;—acquiring second co-ordinate transformation data for each of at least two points, wherein the second co-ordinate transformation data comprise co-ordinate transformation information describing a transformation of the three-dimensional position of the point from the second co-ordinate system to a third co-ordinate system assigned to a second tracked device;—determining, on the basis of the first and second co-ordinate transformation data, second point position data for each of at least two points, wherein the second point position data comprise point position information describing the three-dimensional position of the point within the third co-ordinate system; wherein the second point position data of at least one of the at least two points are determined on the basis of the second co-ordinate transformation data of at least one other of the at least two points.
