Abstract

A method for detecting an optical structure from image sequences of an image recording system. An optical flow field is derived from the image sequences of the image recording system. The vectors of the optical flow field are broken down into components by projection onto a coordinate system of the image recorded by the image recording system. At least one component of the flow vectors is analyzed for a change of direction. The image elements containing a change of direction of a vector component are connected to form a curve.
