US 2014/0152829 A1 · CRUISING LANE RECOGNITION DEVICE

Abstract

A cruising lane recognition device, which is to be mounted on a vehicle, includes a camera which captures an image of an area of the road ahead of a vehicle, a luminance detection section which detects luminances within the images, and a cruising lane recognizing section which recognizes a cruising lane-marker of the road in the images on the basis of the detected luminances. The device further includes a storing section in which a position of the recognized cruising lane-marker is stored, and a virtual cruising lane-marker setting means which sets a virtual cruising lane-marker, based on of a an archival record of the position of a cruising lane-marker which has been stored in the storing section, in a case where the cruising lane recognizing section cannot recognize the cruising lane-marker.

A cruising lane recognition device to be mounted on a vehicle, comprising:

(a) a camera which captures an image of an area including the road ahead of a vehicle:
(b) a luminance detecting section which detects luminances within the images;
(c) a cruising lane-marker recognizing section which recognizes a cruising lane-marker of the road in the photographic images on the basis of the luminances which are detected by the luminance detection section;
(d) a storing section in which a position of the cruising lane that is recognized by the cruising lane recognizing section is stored;
and
(e) a virtual cruising lane-marker setting section which sets a virtual cruising lane-marker on the basis of an archival record of the position of a cruising lane-marker which has been stored in the storing section in a case where the cruising lane-marker recognizing section cannot recognize the cruising lane-marker:
and
(f) a tunnel detecting section which detects a fact that the vehicle is in a tunnel, wherein the virtual cruising lane-marker setting section sets the virtual cruising lane-marker, provided that the tunnel detecting section has detected that the vehicle exists in a tunnel.
