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.
