  • Patent number: 8463039
    Abstract: A barrier partitioning method and device are used for partitioning a barrier area from an image. The method includes: performing edge detecting and partitioning blocks to the image to obtain multiple edge image blocks; performing beeline detection to each edge image block to obtain beelines respectively; for each beeline, determining the line direction of the beeline corresponding to a standard road plane, and determining the edge image block to be a barrier block according to the line direction; forming all the determined barrier blocks to be a barrier area according to a connection principle.
    Type: Grant

  • Patent number: 8406474
    Abstract: A method for identifying barriers in images is disclosed. In the method, images of a current frame and N frame which is nearest to the current frame are obtained, the obtained images of the frames are divided in the same way, and the image of each frame obtains a plurality of divided block regions; the motion barrier confidence of each block region corresponding to the current frame and the N frame which is nearest to the current frame is calculated; whether each block region in the image of the current frame is decided successively according to the motion barrier confidence of each block region corresponding to the current frame and the N frame which is nearest to the current frame; the barriers in the images are determined according to each block region.
