Technical Field

[0001] The present invention relates to the technical field of vehicle lighting lamps, and in particular to a laser coaxial holographic display method based on vehicle lighting lamps. Background Art

[0002] The high beam is an important part of the car lighting system. It has high brightness and long illumination distance, which allows the driver to see the road conditions farther away and make judgments in advance on dimly lit roads, such as in the suburbs or on roads without street lights. However, improper use can easily cause dazzle to the drivers of oncoming vehicles, so it must be used reasonably according to traffic regulations to ensure driving safety.

[0003] Existing automobile high beams can be divided into halogen high beams, xenon high beams, and LED high beams, which provide drivers with a longer visual distance at night, but are prone to cause oncoming vehicles or pedestrians to be unable to see obstacles, roads, and other scenery in the direction of travel, thereby increasing the risk of traffic accidents to a certain extent;

[0004] Therefore, a laser coaxial holographic display method based on vehicle lighting is proposed. Summary of the invention

[0049] The road surface images of the vehicle driving on are a group, and the flatness parameters of the road surface of the vehicle driving on the road surface sensed by the horizontal sensing sensor are a plurality of groups of slope parameters. The estimated interference of the holographic display area relative to the 3D holographic projection is analyzed based on the road surface images and the slope parameters, and the upper and lower limits of the projection size of the 3D holographic projection device are set. The projection scaling ratio of the 3D holographic projection device is set. In combination with the estimated interference analysis result of the holographic display area relative to the 3D holographic projection and the projection scaling ratio, the projection size of the 3D holographic projection device is adjusted.

[0081] Among them, in front of means that the surrounding vehicles are located in front of the current moving vehicle, and after means that the surrounding vehicles are located behind the current moving vehicle.

[0082] In this embodiment, the capture logic of the holographic display area is further limited through the above settings and the limitation of the surrounding vehicle risk area identification logic.

[0083] like Figure 1 As shown, when the projection angle adjustment operation is not performed, the projection position of the 3D holographic projection device is the center of the holographic display area;

[0084] The 3D holographic projection devices are configured in one-to-one correspondence with the high beam lights installed on the vehicle, and the operation target of the projection center of the 3D holographic projection device is determined to be each 3D holographic projection device.
