VEHICLE IMAGE DISPLAY SYSTEM AND CORRECTION METHOD THEREOF
First Claim
1. A vehicle image display system, installed in a vehicle, comprising:
- at least a first image fetching unit, used to fetch at least a front road image;
an image processing unit, connected electrically to said first image fetching unit, used to obtain positions of a lane marking and an obstacle in front based on said front road image, and after correction, it calculates display information of said positions of said lane marking and said obstacle in front, to be overlapped on an image of an actual traffic lane, and generate a control signal and an alarm signal;
a projector unit, connected electrically to said image processing unit, used to project said display information onto at least a viewable panel or a windshield of said vehicle; and
a motor control unit, connected electrically to said image processing unit, said projector unit, and said viewable panel, said motor control unit adjusts focal length or inclination angle of said projector unit, or inclination angle of said viewable panel based on said control signal of said image processing unit, to generate an overlap error correction value to correct said display information.

Abstract
A vehicle image display system and correction method thereof, applicable to a vehicle to perform vehicle information display, comprising following steps, fetch a front road image; obtain positions of a lane marking and an obstacle in front based on said front road image; after correction, calculate display information of said positions of said lane markings and said obstacles in front, to be overlapped with images of an actual traffic lane; utilize a motor control unit to adjust focal length or inclination angle of a projector unit, or inclination angle of a viewable panel, to produce overlap error correction values to correct said display information. Said projector unit projects large area display information overlapped entirely with images of said actual traffic lane onto said viewable panel or windshield, so that a driver can obtain vehicle driving information, to raise vehicle driving safety.

7. A vehicle image display system correction method, applicable to a vehicle to perform vehicle information display and issue vehicle safety alarm, comprising following steps:
-
fetch at least a front road image; obtain positions of a lane marking and an obstacle in front based on said front road image; convert said positions of said lane marking and said obstacle in front into display information; adjust display conditions of said display information, to produce an overlap error correction value; correct said display information based on said overlap error correction value; and project said display information onto said viewable panel. - View Dependent Claims (8, 9, 10)
