METHOD FOR DETECTING AN OPTICAL STRUCTURE

摘要

The invention concerns a method for detecting an optical structure in image sequences of a picture recording system (3). An optical flow field is derived from the image sequences of the picture recording system (3). The vectors of the optical flow field are resolved into components by being projected onto a system of coordinates of the image captured by the picture recording system (3). At least one component of the vectors of the flow is examined in the search for a change of orientation. The image points comprising a change of orientation of a vector component are connected to obtain a curve.
