Abstract

A method and system for correcting misrecognized information of a lane are provided. The method includes extracting lane information of a vehicle information and guard rail information and extracting reference points from each of the lane information and the guard rail information. The reference points are then connected to extract linear lanes and a guard rail and areas and tilts of the lanes and the guard rail are compared to correct the lanes and the guard rail.

Claims

1. A method for correcting misrecognized information of a lane, comprising:

extracting, by a processor, lane information of a vehicle information and guard rail information;

extracting, by the processor, reference points from each of the lane information and the guard rail information;

connecting, by the processor, the reference points to extract linear lanes and a guard rail;

comparing, by the processor, areas and tilts of the lanes and the guard rail;

correcting, by the processor, the lanes and the guard rail; and

transmitting, by the processor, the corrected lanes and guard rail to a lane departure warning system.

2. The method according to claim 1, wherein the comparing of the areas and tilts of the lanes and the guard rail includes:

determining, by the processor, whether the areas and tilts of the lanes and the guard rail are within a set parameter value.

3. The method according to claim 1, wherein the comparing of the areas and tilts of the lanes and the guard rail includes:

comparing, by the processor, the areas between the lanes and the area between the lane and the guard rail; and

comparing, by the processor, the tilt between the lanes and the tilt between the lane and the guard rail.

4. The method according to claim 1, wherein the linear line is formed by connecting a plurality of linear lines.

5. The method according to claim 1, wherein, in the extracting of the linear lanes and the guard rail, at least two reference points are required to form the lane or the guard rail, a difference value in position between remaining reference points and the linear line is determined using a linear line passing through one reference point, and when the difference value is less than a set parameter value, one linear line is extracted, and when the difference value is greater than the set parameter value, a plurality of linear lines are extracted.

6. A system for correcting misrecognized information of a lane, comprising:

a memory configured to store program instructions; and

a processor configured to execute the program instructions, the program instructions when executed configured to;

extract lane information of a vehicle information and guard rail information;

extract reference points from each of the lane information and the guard rail information;

connect the reference points to extract linear lanes and a guard rail;

compare areas and tilts of the lanes and the guard rail;

correct the lanes and the guard rail; and

transmit the corrected lanes and guard rail to a lane departure warning system.

7. The system according to claim 6, wherein the program instructions when executed to compare of the areas and tilts of the lanes and the guard rail include program instructed when executed configured to:

determine whether the areas and tilts of the lanes and the guard rail are within a set parameter value.

8. The system according to claim 6, wherein the program instructions when executed that compare of the areas and tilts of the lanes and the guard rail include program instruction when executed configured to:

compare the areas between the lanes and the area between the lane and the guard rail; and

compare the tilt between the lanes and the tilt between the lane and the guard rail.

9. The system according to claim 6, wherein the linear line is formed by connecting a plurality of linear lines.

10. A non-transitory computer readable medium containing program instructions executed by a processor, the computer readable medium comprising:

program instructions that extract lane information of a vehicle information and guard rail information;

program instructions that extract reference points from each of the lane information and the guard rail information;

program instructions that connect the reference points to extract linear lanes and a guard rail;

program instructions that compare areas and tilts of the lanes and the guard rail;

program instructions that correct the lanes and the guard rail; and

program instructions that transmit the corrected lanes and guard rail to a lane departure warning system.

11. The non-transitory computer readable medium of claim 10, further comprising:

program instructions that determine whether the areas and tilts of the lanes and the guard rail are within a set parameter value.

12. The non-transitory computer readable medium of claim 10, further comprising:

program instructions that compare the areas between the lanes and the area between the lane and the guard rail; and

program instructions that compare the tilt between the lanes and the tilt between the lane and the guard rail.
