<P>PROBLEM TO BE SOLVED: To provide a running road recognition device capable of correctly recognizing a type of multiplex division line. <P>SOLUTION: The running road recognition device 2 includes a white line detection ECU 6 for detecting a lane boundary (a white line) in a multiplex division line, based on the picked-up image of the multiplex division line in front of a vehicle. The storage part 16 of the white line detection ECU 6 previously stores a plurality of patterns for collation including: a template being information of the combination (the number and thickness of the lines) of respective marking lines which constitute the multiplex division line; and lane type information being information of the lane types (a solid line and a dashed line) of the respective marking lines. The white line detection ECU 6 extracts the multiplex division line from the picked-up image of the multiplex division line, determines the line type of each marking line constituting the multiplex division line, based on the extraction, determines whether a section is the section of the multiplex division line or not, collates the results with the patterns for collation, and then, identifies the type of multiplex division line. <P>COPYRIGHT: (C)2007,JPO&INPIT |
