A method performed by a surgical system. The method includes receiving a first image from an endoscope, the first image having a surgical instrument at a first location within a field of view of the endoscope. The method matches a three-dimensional (3D) model of the surgical instrument to the first image. The method receives a second image receives a second image from the endoscope, the second image having the surgical instrument at a second location within the field of view of the endoscope, and matches the 3D model of the surgical instrument to the second image. The method estimates a distance between the first and second locations based on both matchings and one or more parameters of the endoscope.

Method and system for estimating positional data in images

A data model which is designed for being superposed with an image of a real object in an optical object tracking process is determined by the following steps: providing a three-dimensional CAD model () for representing the real object, and thereafter there are different synthetic two-dimensional views (to) of said CAD model () generated. Each generated view (to) is subjected to edge extraction for determining at least one extracted edge () in the respective view, with the edges () extracted from said respective views (to) being transformed to a three-dimensional contour model () corresponding to said data model to be determined. Permits rapid and efficient generation of a contour model as a data model intended for being superposed with an image of a real object.
