Abstract: This paper put forward an inverse perspective mapping method for general road. By modeling the vertical profile of a road using stereo vision, and substituting the modeled height into the process of road image formation, an inverse perspective mapping of a general road can be achieved. The experiment validates that the method is capable to deal with the situations of inverse perspective mapping such as downhill, uphill or uneven road image.  

Key words: inverse perspective mapping, bird’seye view, road modeling, stereo vision
