Lane boundary detector
First Claim
1. A boundary detector comprising:
- a camera that is mounted on a vehicle and picks up an image of a road surface;
a candidate line detecting unit that detects a candidate line of a lane boundary position drawn on the road surface based on image information of the image supplied from the camera;
a lane boundary position selecting unit that selects the lane boundary position based on the candidate line of the lane boundary position detected by the candidate line detecting unit;
an additional lane boundary position selecting unit that selects a lane boundary position of an additional lane that is added to a main lane based on the candidate line of the lane boundary position detected by the candidate line detecting unit; and
an additional processing unit that stops adopting the lane boundary position selected by one of the lane boundary position selecting unit and the additional lane boundary position selecting unit for a predetermined time period when the additional lane boundary position selecting unit selects a lane boundary position of the additional lane.

Abstract
A boundary detector includes a candidate line detecting unit that detects a candidate line of a lane boundary position drawn on the road surface based on image information from a camera. The detector also includes a lane boundary position selecting unit that selects the lane boundary position based on the candidate line; an additional lane boundary position selecting unit that selects a lane boundary position of an additional lane that is added to a main lane based on the candidate line; and an additional processing unit that stops adopting the lane boundary position for a predetermined time period when the additional lane boundary position selecting unit selects a lane boundary position of the additional lane.

6. A boundary detecting method comprising:
-
detecting a candidate line of a lane boundary position drawn on a road surface based on image information of an image supplied from a camera that is mounted on a vehicle and that picks up the image of the road surface;
selecting the lane boundary position based on the candidate line of the detected lane boundary position;
selecting a lane boundary position of an additional lane that is added to a main lane based on the candidate line of the detected lane boundary position detected; and
stopping adopting one of the lane boundary positions for a predetermined time period when a lane boundary position of the additional lane is selected. - View Dependent Claims (7, 8, 9, 10)
