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 second lane information that is previously stored;
wherein the lane information includes information about at least one of a lane type, a lane color, and a lane departure situation; and
wherein the fault detection is caused by a faded lane or a noise environment.

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.

7. A lane correction apparatus comprising:
-
a lane information transceiver connected to a lane departure warning system for receiving first lane information detected by the lane departure warning system; a lane feature generator for comparing the first lane information received at a present time point through the lane information transceiver with second lane information previously stored in order to generate a feature of the first lane information according to a comparison result; and a lane fault detection sensor for identifying a degree of variation of a lane varying as a function of time based on the feature of the first lane information generated through the lane feature generator, and for sensing whether a fault detection of the first lane information exists based on the identified degree of variation; wherein the fault detection is caused by a faded lane or a noise environment. - View Dependent Claims (8, 9, 10, 11, 12)
