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 HUD (Head-Up Display), comprising:
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.

2 . The coordinate matching apparatus of claim 1 , further comprising a vehicle posture measuring unit 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 2 , wherein the vehicle posture measuring unit comprises one or more of a vibration sensor, acceleration sensor and gyro sensor.

4 . The coordinate matching apparatus of claim 1 , wherein the surrounding information measuring unit comprises one or more of a camera, radar and LiDAR (Light Detection And Ranging).

5 . The coordinate matching apparatus of claim 1 , wherein the control unit converts the position of the object sensed by the surrounding information measuring unit such that a view angle measured by the surrounding information measuring unit coincides with a view angle of the image displayed through the HUD.

6 . The coordinate matching apparatus of claim 1 , wherein the control unit matches the position of the object sensed through the surrounding information measuring unit with the coordinate of the HUD through a viewpoint conversion matrix for matching the coordinate of the surrounding information measuring unit corresponding to the installation position with the coordinate of the HUD.

7 . A coordinate matching method for HUD, comprising:
receiving, by a control unit, an image of an object sensed by a surrounding information measuring unit; matching a coordinate of the surrounding information measuring unit corresponding to an installation position with a coordinate of the HUD, and displaying a HUD image by matching the position of the object with the coordinate of the HUD.

8 . The coordinate matching method of claim 7 , wherein the matching of the coordinate of the surrounding information measuring unit 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 a vehicle posture measuring unit.

9 . The coordinate matching method of claim 8 , wherein the vehicle posture measuring unit comprises one or more of a vibration sensor, acceleration sensor and gyro sensor.

10 . The coordinate matching method of claim 7 , further comprising converting the position of the object sensed by the surrounding information measuring unit such that a view angle measured by the surrounding information measuring unit coincides with a view angle of the image displayed through the HUD.

11 . The coordinate matching method of claim 7 , wherein the displaying of the HUD image comprises matching the position of the object sensed through the surrounding information measuring unit with the coordinate of the HUD through a viewpoint conversion matrix for matching the coordinate of the surrounding information measuring unit corresponding to the installation position with the coordinate of the HUD.

12 . The coordinate matching method of claim 7 , wherein the surrounding information measuring unit comprises one or more of a camera, radar and LiDAR.
