Abstract

A lane display device using an outside mirror is disclosed. The lane display device includes a lane detection unit detecting a lane from a side view image of a vehicle; a control unit determining a position of the lane on an outside mirror corresponding to a position of the lane detected by the lane detection unit, and controlling the outside mirror to display the lane in the determined position; and the outside mirror including a display unit and a half mirror and displaying the lane.

First claim

What is claimed is:

1. A lane display device using an outside mirror of a vehicle, the lane display device comprising:
an outside mirror comprising a half mirror and a display placed behind the half mirror for displaying images through the half mirror;
a lane detection unit configured for detecting a lane from a side view image captured by a camera mounted on the vehicle; and
a control unit configured for determining a position of the lane reflected on a surface of the half mirror and further configured for controlling the display for displaying a lane mark such that the lane reflected on the surface of the half mirror coincides the lane mark displayed on the display from a driver's view,
wherein the control unit stores an algorithm for matching the position of the lane detected by the lane detection unit with the position of the lane reflected on the outside mirror.

2. The lane display device according to claim 1 , wherein the lane detection unit is configured to perform inverse perspective mapping (IPM) in order to remove an effect of perspective from the image.

3. The lane display device according to claim 1 , wherein when the lane detection unit comprises:
a right lane detector detecting a lane from a right side view image of the vehicle; and
a left lane detector detecting a lane from a left side view image of the vehicle.

4. A lane display method using an outside mirror of a vehicle, the lane display method comprising:
detecting, by a lane detection unit, a lane from a side view image captured by a camera mounted on the vehicle;
determining, by a control unit, a position of the lane reflected on a half mirror of the outside mirror; and
displaying, on a display placed behind the half mirror, a lane mark such that the lane reflected on the half mirror coincides the lane mark displayed on the display from a driver's view,
wherein the control unit stores an algorithm for matching the position of the lane detected by the lane detection unit with the position of the lane reflected on the outside mirror.

5. The lane display method according to claim 4 , wherein the detecting of the lane comprises performing inverse perspective mapping (IPM) in order to remove an effect of perspective from the side view image.

6. The lane display method according to claim 4 , wherein the detecting of the lane comprises:
detecting a lane from a right side view image of the vehicle; and
detecting a lane from a left side view image of the vehicle.
