Lane boundary marking line detection device and electronic control device

摘要

A lane boundary marking line detection device includes an imaging device, a lane boundary detection unit, a lane boundary marking line search unit. The lane boundary detection unit detects first and second lane boundaries based on image information in an imaging area. The lane boundary marking line search unit searches for a lane boundary marking line on a road surface on a second lane boundary's side based on a position of the first lane boundary, sets search lines on the road surface on the second lane boundary's side based on shape information on the first lane boundary, and acquires search line brightness information based on the image information. When not determining that there is the search line that is most probable as the lane boundary marking line, the lane boundary marking line search unit does not select any of the search lines as the lane boundary marking line candidate line.
