LANE RECOGNITION METHOD AND SYSTEM
First Claim
1. A lane recognition method of recognizing a lane in which a vehicle is traveling, comprising:
- detecting, by an object detector, a plurality of locations of a plurality of fixed objects at a left side and a right side of a traveling directional road;
capturing, by an imaging device, a photograph of a road surface ahead;
calculating, by a controller, the entire width of the traveling directional road based on the locations of the fixed objects at the left side and the right side;
calculating, by the controller, the width of a traveling lane from the photograph of the road surface; and
calculating, by the controller, the lane in which the vehicle is traveling based on the calculated width of the traveling lane and the entire width of the traveling directional road.

Abstract
Disclosed herein is a method of recognizing the location of a current lane in which a vehicle is traveling, using a radar and an imaging device. The method includes: detecting the locations of the fixed objects using an object detector; capturing a photograph of the road surface ahead using an imaging device; calculating, by a controller, the entire width of a traveling road based on the locations of the fixed objects at the left side and the right side; calculating, by the controller the width of a traveling lane from the photograph of the road surface; and calculating, by the controller, the lane in which the vehicle is traveling based on the calculated width of the traveling lane and the entire width of the traveling road.

8. A lane recognition method of recognizing a lane in which a vehicle is traveling, comprising:
-
detecting, by an object detector, the location of a central reservation on a traveling directional road; capturing, by an imaging device, a photograph of a road surface ahead; calculating, by a controller, a width of a traveling lane from the photograph of the road surface; and calculating, by the controller, the lane in which the vehicle is traveling based on the calculated width of the traveling lane and the location of the central reservation.

9. A system for recognizing a lane, comprising:
-
an object detector mounted on a vehicle, wherein the object detector is configured to detect a plurality of locations of a plurality of fixed objects at a left side and a right side of a road; an imaging device mounted on the vehicle, wherein the imaging device is configured to capture a photograph of a road surface of the road; and a controller configured to; recognize a lane in which the vehicle is traveling, using signals from the object detector and the imaging device; calculate the entire width of the traveling directional road based on the locations of the fixed objects at the left side and the right side; calculate the width of a traveling lane from the photograph of the road surface; and calculate the lane in which the vehicle is traveling based on the calculated width of the traveling lane and the entire width of the traveling directional road. - View Dependent Claims (10, 11, 12, 13)
