Abstract

A coordinate matching apparatus for HUD (Head-Up Display) may include: an HUD configured to display an image on the windshield of a vehicle; a surrounding information measuring unit installed on the vehicle and configured to sense an object in front of the vehicle; and a control unit configured to match a coordinate of the surrounding information measuring unit corresponding to an installation position with a coordinate of the HUD, and display the image by matching the position of the object sensed by the surrounding information measuring unit with the coordinate of the HUD.

First claim

What is claimed is:

1. A coordinate matching apparatus for Head-Up Display (HUD), comprising:
an HUD configured to display an image on the windshield of a vehicle;
at least one of a camera, radar and LiDAR (Light Detection And Ranging) installed on the vehicle and configured to sense an object in front of the vehicle; and
a control unit configured to match a coordinate of the at least one of a camera, radar and LiDAR corresponding to an installation position with a coordinate of the HUD based on a viewpoint conversion matrix which is defined depending on a view angle measured by the at least one of a camera, radar and LiDAR and a view angle of the HUD, and display the image by matching a position of the object sensed by the at least one of a camera, radar and LiDAR with the coordinate of the HUD.

2. The coordinate matching apparatus of claim 1 , further comprising at least one of a vibration sensor, acceleration sensor and gyro sensor configured to measure vibration and posture of the vehicle,
wherein the control unit corrects the coordinate of the HUD for a coordinate change based on the posture of the vehicle.

3. The coordinate matching apparatus of claim 1 , wherein the control unit converts the position of the object sensed by the least one of a camera, radar and LiDAR such that the view angle measured by the at least one of a camera, radar and LiDAR coincides with the view angle of the HUD.

4. A coordinate matching method for a Head-Up Display (HUD), comprising:
receiving, by a control unit, an image of an object sensed by at least one of a camera, radar and LiDAR;
matching, by the control unit, a coordinate of the at least one of a camera, radar and LiDAR corresponding to an installation position with a coordinate of the HUD based on a viewpoint conversion matrix which is defined depending on a view angle measured by the at least one of a camera, radar and LiDAR and a view angle of the HUD, and
displaying a HUD image by matching a position of the object with the coordinate of the HUD.

5. The coordinate matching method of claim 4 , wherein the matching of the coordinate of the at least one of a camera, radar and LiDAR with the coordinate of the HUD comprises correcting the coordinate of the HUD when a coordinate change corresponding to a vehicle posture is received from at least one of a vibration sensor, acceleration sensor and gyro sensor.

6. The coordinate matching method of claim 4 , further comprising converting the position of the object sensed by the at least one of a camera, radar and LiDAR such that the view angle measured by the at least one of a camera, radar and LiDAR coincides with the view angle of the HUD.
