An embedded system for vehicle surrounding monitoring

In this paper, we present a low-cost driving assistant system which can provide the surrounding image of a vehicle in a bird´s-eye view. By implementing a fast image stitching algorithm on an embedded platform, this system can generate the around-vehicle view in real time from four fisheye cameras mounted around the vehicle. Moreover, we also propose a dynamic boundary determination method to allow the automatic switch among image sources and to reduce the chance of missing obstacles in the overlapping area. With this bird´s-eye view surrounding monitoring system, drivers can visually perceive the condition of the surrounding environment. Driving and parking can then become more easily and safely.
