Method and device for determining an optical flow from an image sequence taken by a camera of a vehicle

摘要

The invention relates to a method for determining an optical flow on the basis of an image sequence recorded by a camera (104) of a vehicle (100). In this case, at least one input signal (108), which represents a vehicle environment and / or driving situation of the vehicle (100) detected using at least one sensor (110) of the vehicle (100) and / or a result of a previous determination of the optical flow, and receive the image sequence representing image signal (106) received. Using the input signal (108), a time difference value is determined. Using the image signal (106), at least two frames of the image sequence staggered by the time difference value are selected. Finally, matching pixels in the frames are detected to determine the optical flux using the matched pixels.
