Abstract
The present invention relates to a computer-implemented medical method of determining a spatial position of a medical optical observation device (1), the method comprising executing, on a processor of a computer (2), the steps of:—acquiring position data describing, for a plurality of points in time, the spatial position of the observation device (1) within a co-ordinate system of a medical tracking system (3);—determining, based on the position data, average position data describing an average value for the position of the observation device (1) within the co-ordinate system of the medical tracking system (2);—acquiring image data describing a plurality of images acquired at the plurality of points in time via a camera (4) assigned to the observation device (1) and detecting the field of view (5) of the observation device (1);—determining, based on the image data, optical flow data describing an optical flow for the plurality of images;—determining, based on the average position data and the optical flow data, focal plane position data describing a spatial position of the focal plane (6) of the observation device (1). The present invention further relates to a corresponding comput…
