Problems solved by technology

[0003] When the driver observes the image presented by the image source, due to the relatively short distance between the driver's eyes and the image presented by the image source, the driver finds the image seen by the left eye or the image seen by the right eye when observing the image. There is a horizontal parallax between the real environment and the image source that the driver sees deviates from the real environment, reducing the driver's experience with AR-HUD

Embodiment 1

[0042] see Figure 1a A schematic structural diagram of a head-up display device is shown. This embodiment proposes a head-up display device, including: an image source 100 and a curved mirror 102 .

[0043]The image source 100 is set at a position close to the focal plane of the curved mirror 100 or at a position where the focal plane of the curved mirror 102 is located.

[0044] The image source 100 can emit light.

[0045] Further, the image source 100 can emit light to present an image.

[0046] The curved mirror 102 reflects the incident light out of the head-up display device, so that the light reflected out of the head-up display device can form a long-distance virtual image.

[0047] The curved mirror 102 may be, but not limited to: a spherical mirror, a hyperbolic mirror, a parabolic mirror, and a free-form mirror.

[0048] The distant virtual image is used to eliminate the horizontal parallax when the observer watches the image.

[0049] Here, the principle of the...

Embodiment 2

[0116] see image 3 Shown is a schematic structural diagram of a vehicle cockpit installed with a head-up display device. This embodiment proposes a head-up display device, including: an image source 100 .

[0117] The image source 100 is installed in a vehicle; at least one surface of the dashboard 4700 of the vehicle has a curved reflective structure 4702 .

[0118] The image source 100 is set in the vehicle near the focal plane of the curved reflective structure 4702 or at the position of the focal plane of the curved reflective structure 4702 .

[0119] The image source 100 can emit light.

[0120] Further, the image source 100 can emit light to present an image.

[0121] The curved surface reflection structure 4702 reflects the light emitted by the image source 100 to the vehicle windshield 2500 , so that the light reflected to the vehicle windshield 2500 can form a long-distance virtual image.

[0122] The distant virtual image is used to eliminate the horizontal para...

Embodiment 3

[0147] see Figure 4 with Figure 5 As shown in the structural diagrams of different vehicle cockpits, this embodiment proposes an imaging system, including: a vehicle windshield 2500 and the HUD 2502 described in Embodiment 1.

[0148] in, Figure 4 The HUD2502 shown in the Figure 5 The HUD2502 shown in is has a flat mirror.

[0149] The vehicle windshield 2500 reflects the light received from the head-up display device 2502 to the observer's eye box area, so that the observer can observe that the vehicle windshield is moving away from the head-up display device A distant virtual image of one side of 2502.

[0150] The vehicle windshield 2500 may be, but not limited to, transparent or non-transparent media with a certain inclination angle, such as a vehicle windshield, a plane mirror coated with an opaque reflective layer, or a transparent resin plate.

[0151] This embodiment also proposes a vehicle, which may include the above-mentioned imaging system.

Abstract

The invention provides head-up display equipment, an imaging system and a vehicle. The head-up display equipment comprises an image source and a free-form surface mirror, wherein the image source is arranged at a position close to the focal plane of the curved mirror or at a position where the focal plane of the curved mirror is located; the image source can emit light; the curved mirror reflectsthe incident light out of the head-up display equipment, so that the light reflected out of the head-up display equipment can form a long-distance virtual image; and the long-distance virtual image isused for eliminating horizontal parallax when an observer watches the image. According to the head-up display equipment, the imaging system and the vehicle provided by the embodiment of the invention, the long-distance virtual image projected by the image source can be visually and perfectly fused with the real environment, so that the horizontal parallax generated when a driver observes AR-HUD imaging is eliminated.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular, to a head-up display device, an imaging system and a vehicle. Background technique [0002] Currently, an augmented reality head-up display (Augmented Reality Head Up Display, AR-HUD) is one of many head-up display devices (Head Up Display, HUD), which can achieve a good visual experience. Based on the imaging principle of AR-HUD, the image projected by the image source needs to be integrated with the real environment. For example, the direction arrow needs to be accurately integrated with the road to achieve a good visual effect. [0003] When the driver observes the image presented by the image source, due to the relatively short distance between the driver's eyes and the image presented by the image source, the driver finds the image seen by the left eye or the image seen by the right eye when observing the image. There is a horizontal parallax between the real enviro...
