Document Type and Number:
WIPO Patent Application WO/2010/069168
Kind Code:
A1
Abstract:
A method and apparatus for estimating self-motion parameters of vehicle, the method comprises: choosing an image block area in accordance a predetermined condition from image block areas divided in current frame; under a condition of different motion parameters, calculating a corresponding coordinate in a neighboring frame of a pixel in the image block area chose from current frame according to a previously created pixel motion model; calculating the confidence of different motion parameters based on the characters of pixels in the image block area chose from current frame and the characters of pixels at the corresponding coordinate in the neighboring frame; and determining a motion parameter with the highest confidence as the self-motion parameter of vehicle.
