Vehicle image display system and correction method thereof

Abstract

The invention provides a vehicle image display system and a correction method thereof. The automobile image display system is arranged on a vehicle to display images, can read at least one image of a road ahead, can obtain the positions of lane lines and obstacles ahead according to the image of the road ahead, and can work out display projection information which can be superposed with the positions of lane lines and obstacles ahead on an actual lane after correction is conducted. The focal distance conversion or the dip angle of a projection unit or the dip angle of a visual flat panel can be adjusted by using a motor control unit, so as to generate a superposition error correction value to correct the display projection information. In combination with hardware adjustment and software correction, large-area display projection information which is fully superposed with actual road images can be projected onto the visual flat panel or a windscreen of the vehicle by using the projection unit, a driver is enabled to obtain intuitive information of road conditions and the driving safety is further improved.

Description

technical field [0001] The present invention relates to a vehicle image display system and its correction method, in particular to a vehicle image display system capable of projecting large-area display projection information completely superimposed with actual road images and its correction method. Background technique [0002] With the development of science and technology, life is rich, motor vehicles are becoming more and more popular in every family, and the convenience of transportation is continuously improved due to the advancement of vehicle technology. However, with the frequent use of vehicles, the number of traffic accidents increases, and most of the accidents are caused by collision cases. In order to improve the driving safety of vehicles, the head-up display device has become the basic equipment of many vehicles. It can project driving information, such as the information displayed on the general instrument panel, on the front windshield of the vehicle, so th...

Problems solved by technology

[0004] However, the head-up display must be installed in the limited space in the car, most of which are miniaturized, and relatively limited to a small area for projection display

Therefore, the displayed information and the actual road image cannot intuitively judge the actual road conditions. In addition, the depth of field will also be caused by the driver's driving habits, such as height, distance from the front windshield, or driving trajectory. The angle of view changes, so it is impossible for the driver to accurately grasp the relative distance relationship with the vehicle in front, the width and the path that can be driven
