Lane correction system, lane correction apparatus and method of correcting lane
First Claim
Patent Images
1. A lane correction system comprising:
- an image acquisition apparatus for acquiring a forward image in front of a vehicle;
a lane detection apparatus for receiving the forward image from the image acquisition apparatus to detect lane information based on the forward image; and
a lane correction apparatus for receiving first lane information detected at a present time from the lane detection apparatus and for sensing whether a fault detection of the first lane information exists by comparing the first lane information with a second lane information which is previously stored,wherein the lane correction apparatus corrects the first lane information when the fault detection is sensed in the first lane information and transfers the corrected first lane information to the lane detection apparatus;
wherein the lane correction apparatus detects a feature of the first lane information by using the received first and second lane information, and senses whether the fault detection of the first lane information exists by using the detected feature; and
wherein the feature includes a degree of variation of a lane information as a function of time.

Abstract
The embodiment provides a method of correcting a lane. The method includes receiving first lane information detected by a lane departure warning system; comparing the received first lane information with previously stored second lane information to identify a degree of variation of a lane as a function for time; sensing whether a fault detection of the received first lane information exists according to the identified degree of variation of the lane; correcting the received first lane information when the fault detection of the first lane information is sensed; and transmitting the corrected lane information to the lane departure warning system.

6. A lane correction apparatus comprising:
-
a lane information transceiving unit connected to a lane departure warning system for receiving first lane information detected by the lane departure warning system; a lane feature generating unit for comparing the first lane information received at a present time point through the lane information transceiving unit with second lane information previously stored in order to generate a feature of the first lane information according to a comparison result; a lane fault detection sensing unit for identifying a degree of variation of a lane varying as a function for time based on the feature of the first lane information generated through the lane feature generating unit, and for sensing whether a fault detection of the first lane information exists based on the identified degree of variation; and a lane information correcting unit for correcting a fault-detected first lane information when the fault detection of the first lane information is sensed through the lane fault detection sensing unit, and for transferring the corrected first lane information to the lane departure warning system. - View Dependent Claims (7, 8, 9, 10, 11, 12)
