Abstract
A method for compensating a road line includes deriving a length of a left road line and a length of a right road line, recognized by a sensor, and determining a left road line level and a right road line level based on the length of the left road line and the length of the right road line; correcting the left road line level and the right road line level based on a change in the lengths of the left road line and the right road line or a change in curvatures of the left road line and the right road line; calculating a correction coefficient based on the corrected left road line level and the corrected right road line level; and correcting, by the correction coefficient, information about a road line with a lower level of the corrected left road line level and the corrected right road line level.
Claims12
A method for compensating a road line, the method comprising:
- deriving, by a sensor, a length of a left road line and a length of a right road line, which are recognized by the sensor;
- determining, by a controller, a left road line level and a right road line level based on the length of the left road line and the length of the right road line, each road line level ranging from 1 to n, n being greater than 1;
- correcting, by the controller, the left road line level and the right road line level based on a change in the lengths of the left road line and the right road line or a change in curvatures of the left road line and the right road line;
- calculating, by the controller, a correction coefficient based on the corrected left road line level and the corrected right road line level;
- and
- correcting, by the correction coefficient, information about the road line with a lower level of the corrected left road line level and the corrected right road line level to compensate the road line.
A system for compensating a road line, the system comprising:
- a sensor configured to sense and derive a length of a left road line and a length of a right road line;
- and
- a controller configured to:
- determine a left road line level and a right road line level based on the length of the left road line and the length of the right road line, each road line level ranging from 1 to n, n being greater than 1;
- correct the left road line level and the right road line level based on a change in the length of the left road line and the right road line or a change in curvatures of the left road line and the right road line;
- calculate a correction coefficient based on the corrected left road line level and the corrected right road line level;
- and
- correct, by the correction coefficient, information about the road line with a lower level of the left road line level and the right road line level to compensate the road line.
