Abstract
A computer-implemented method for calculating information relative to a relative speed between an object and a camera, based on two images of the object acquired by the camera. The method comprises: determining a value of an optical flow between the two images; and, altogether with or after the determination of the value the optical flow, determining at least one parameter of the transformation, using the optical flow; and calculating information relative to a relative speed between the object and the camera, based on said at least one parameter of the transformation.
