| Abstract: | In order to identify road junctions from vector map efficiently and precisely,this paper first proposed an identification method based on perceptual grouping method and structural characteristics of the road junctions.The experiments carried out to validate the algorithm were then introduced,which identified two typical areas of simple and complicated road network respectively.The results showed that the algorithm could identify road junctions efficiently and precisely with stability and speed. |
