A road boundary detection method based on two kinds of boundaries is presented. Firstly, the road boundaries are obtained by a searching method based on local direction, and they are referred to as first category of road boundaries. Secondly, the road areas are obtained by a region growing method based on seed-windows, and they are referred to as second category of road boundaries. Thirdly, the two kinds of boundaries are integrated: According to the close location assumption, the position of the initially real road boundaries are obtained. According to the spatial continuity assumption, the real road boundaries and the false road boundaries are determined. The wrong boundaries are eliminated. Lastly, the final real road boundaries are formed by post processing.
