Problems solved by technology

However, the current HUD products on the market have the disadvantage of small depth of field. The distance from the driver's eyes to the actual displayed screen can only reach 2-3 meters. Therefore, the traditional HUD can only simply present the information in the driving 2-3 meters in front of the driver, the augmented reality effect cannot be achieved, that is, the effect of combining projected information with the actual road surface

Embodiment Construction

[0035] Such as Figure 1-3 As shown, an augmented reality head-up display system includes a projection module 11 , an imaging element 12 , an optical flat mirror 13 , a concave mirror 14 and a holographic optical film 15 .

[0036] The projection module 11 is used to project light, which is arranged obliquely upward, and the projecting direction is obliquely upward. The source image is projected onto the imaging element 12 through the projection module 11 .

[0037] In this embodiment, the projection module 11 adopts a laser projection module, which can provide higher brightness than LED, and has the advantages of good monochromaticity and coherence, and the surface brightness loss is relatively small when the picture is enlarged.

[0038] The imaging element 12 and the flat optical mirror 13 are sequentially arranged on the projection path of the projection module 11 .

[0039] The imaging element 12 is used to allow the light to pass through to form a real image and form a ...

Abstract

The invention discloses an augmented reality head-up display system, which comprises a projection module, an imaging element, an optical plane mirror, a concave mirror and a holographic optical film,wherein the projection module is used for projecting light rays; the imaging element is used for forming a real image of the light rays and then forming a mirror image on the optical plane mirror; theoptical plane mirror is used for reflecting the mirror image onto the concave mirror, and the imaging element and the optical plane mirror are arranged on a projection path of the projection module;the concave mirror is used for magnifying the mirror image reflected by means of the optical plane mirror and projecting the mirror image onto the holographic optical film; and the holographic opticalfilm is fixed on a windshield of a vehicle. The augmented reality head-up display system and an augmented reality head-up display method increase an upper limit of a depth-of-field distance, can realize the effect of combining virtual indication information with an actual road, and improve the viewing angle of the driver.

Description

technical field [0001] The invention belongs to the technical field of automotive electronics, in particular to an augmented reality head-up display system and method. Background technique [0002] With the popularity of automobile consumption, people have higher and higher requirements for intelligence and safety when driving automobile products. As a display technology that can project driving information on the driving direction, head-up display (HUD) can facilitate driving. The driver observes the car information during driving, and the eyes do not need to leave the driving direction, which improves the driving safety. However, the current HUD products on the market have the disadvantage of a small depth of field. The distance from the driver's eyes to the actual displayed screen can only reach 2-3 meters. Therefore, the traditional HUD can only simply present the information on the driving screen. 2-3 meters in front of the driver, the augmented reality effect cannot b...
