Abstract
The invention provides a method for determining an orientation of a tool for performing a medical intervention on a subject. The method includes obtaining image data for an image of a surface of, or over, a subject, a tool adjacent the surface and a tool shadow on the surface, the tool shadow resulting from light incident on the tool generated by way of at least one light source positioned at a predetermined position relative to the image sensor. A representation of the surface is obtained and representations of the tool and the tool shadow are segmented from the image data and used to determine an elevation angle of the tool. The orientation of the tool is determined based on the segmented representation of the tool, the segmented representation of the tool shadow and the elevation angle.
