Description
Technical Field
The application relates to the field of intelligent automobiles, in particular to an augmented reality display device.
Background
Head-up displays (HUDs) were originally introduced on airplanes to reduce the frequency of the pilot looking up the disk and to avoid pilot distractions. Subsequently, the car also starts to follow the installation slowly due to the advantages of the HUD device. The HUD equipment can enable a user to observe information such as speed limit indication, route maps and the like without lowering head or turning head as much as possible. In contrast to the HUD, the augmented reality head-up display (AR-HUD) not only displays information, but also changes the way in which the driver observes the information.
In combination with Advanced Driving Assistance System (ADAS), lane departure warning system, and Auto Cruise Control (ACC), the AR-HUD unlocks more poses. For example, once the user's vehicle deviates from the lane, the AR-HUD system draws a red line at the edge of the lane line to alert the user. When the ACC system works, the driver can see a bright band of a mark at the rear part of the front vehicle. Namely, the AR-HUD not only displays information, but also simulates and observes the information. This is mainly due to the fact that AR-HUD technology uses an increased projection surface and digital micromirror elements to generate the image elements, while the image mirrors on the image screen are ultimately directed towards the windshield. And the display information after the AR-HUD technology is directly projected on a road at the angle of the user and is fused with the traffic condition. Therefore, with the aid of the AR-HUD, the driver does not need to directly raise the head to observe the information during driving, and the information and the lane line are fused.
Although the AR HUD is strongly demanded, the AR HUD needs to display road surface level information, and therefore, a screen size is demanded to be larger and an imaging distance is longer. This results in the AR HUD being relatively bulky, but for most current vehicle models, the front instrument panel is limited by air conditioning ducts, vehicle body structures, etc., and it is difficult to provide sufficient space, thus limiting the wide use of the AR HUD.

Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the embodiments of the present application are described below with reference to the accompanying drawings, and it is obvious that the described embodiments are only some embodiments of the present application, but not all embodiments. As can be known to those skilled in the art, with the advent of new application scenarios, the technical solution provided in the embodiments of the present application is also applicable to similar technical problems.
The HUD is used for reducing the frequency of raising heads of pilots to look at the disk and avoiding the unconcentration of pilot force. Subsequently, the car also starts to follow the installation slowly due to the advantages of the HUD device. The HUD equipment can enable a user to observe information such as speed limit indication, route maps and the like without lowering head or turning head as much as possible. And compared with the HUD, the augmented reality head-up display not only displays information, but also changes the way in which the driver observes the information. Fig. 1 shows a schematic structural diagram of the augmented reality head-up display optical system, which specifically includes an automobile windshield 2, an augmented reality head-up display device 1, and human eyes 3. Wherein, this augmented reality new line display device 1 includes speculum 12, catadioptric mirror 13 and looks like source 11, and the light that is sent by looking like source 11 is incited to speculum 12 through catadioptric mirror 13, and on the car windscreen 2 of reprojection, human eye 3 can see the virtual image of formation of image in the car place ahead through car windscreen 2. In this configuration, in order to obtain a virtual image projected at a long distance in the augmented reality head-up display device 1, first, the magnification of the magnifying/folding mirror 13 is considered. However, the magnification cannot be increased infinitely, which is generally considered to be less than 7, otherwise the binocular disparity can be difficult to control, causing the driver to produce a feeling of vertigo. Moreover, the image distortion is serious, and the image distortion correction at the later stage is difficult to restore. Therefore, when the magnification reaches the limit, the increase of the object distance must be considered. The augmented reality head-up display device 1 is installed inside an instrument panel in a vehicle, and is generally provided with various parts such as a wind pipe, a vehicle-mounted data line, a steering column support, an instrument and the like at a corresponding position. The space that can be given to the augmented reality heads-up display device 1 is extremely limited, and the models are completely different. It follows that the object distance between the folding mirror 13 and the image source 11 is also substantially limited to a certain range. Even if a polygon mirror is used, the object distance is not increased much, and the optical path and the structure are complicated.
In order to solve this problem, an embodiment of the present application provides an augmented reality display device 100, which is specifically configured as shown in fig. 2, and includes: an imaging device 101, an image processing device 102, and a diffusion screen 103; the imaging device 101 and the image processing device 102 are disposed in an instrument panel 1 in a vehicle; the diffusion screen 103 is placed in the upper portion of the vehicle interior; the imaging light generated by the imaging device 101 generates a real image on the diffusion screen 103, and the real image displayed on the diffusion screen 103 is reflected to the windshield 2 by the image processing device 102. In the technical scheme that this embodiment provided, this imaging device and this image processing device are integrated in this augmented reality display device to a diffusion screen is provided, make the real image that imaging device produced map to exterior space, greatly increase and improve optics object distance, can easily obtain under the condition of the projection virtual image of long distance, big picture, reduce augmented reality display device's inside light path transmission, thereby reduce this augmented reality display device's volume.

in one possible implementation, the diffuser screen 103 is mounted in the upper middle portion of the side of the windscreen 2 in the vehicle, as shown in fig. 3. At this time, the augmented reality display device 100 provided in the embodiment of the present application includes an imaging device 101, an image processing device 102, and a diffusion screen 103, where the imaging device 101 and the image processing device 102 are disposed at the instrument desk 1 in the vehicle, and imaging light generated by the imaging device 101 is mapped on the diffusion screen 103 to generate a real image; the real image displayed on the diffusion screen 103 is then reflected by the image processing device 102 to the windshield 2 of the vehicle and into the driver's eye 3. The diffuser screen 103 is located on the incident side of the image processing device 102, and the windshield 2 is located on the reflection side of the image processing device 102, so that the real image displayed by the diffuser screen 103 is reflected to the windshield 2 through the image processing device 102, and then enters the eyeball 3 of the driver. In the present embodiment, the arrow direction in the drawing is used to indicate the path of the imaging light of the imaging device 101.
In another possible implementation, as shown in fig. 4, the diffuser screen is mounted to the upper middle portion of the vehicle exterior side of windshield 2. At this time, the augmented reality display device 100 provided in the embodiment of the present application includes an imaging device 101, an image processing device 102, and a diffusion screen 103, where the imaging device 101 and the image processing device 102 are disposed at the instrument desk 1 in the vehicle, and imaging light generated by the imaging device 101 is reflected by the windshield 2 and then is mapped on the diffusion screen 103 to generate a real image; then, the real image displayed on the diffusion screen 103 is reflected by the image processing device 102 to the windshield 2 of the vehicle after being refracted by the windshield 2, and is reflected to the driver's eye 3. The diffuser screen 103 is located on the incident side of the image processing device 102, and the windshield 2 is located on the reflection side of the image processing device 102, so that the real image displayed by the diffuser screen 103 is reflected to the windshield 2 through the image processing device 102, and then enters the eyeball 3 of the driver. In the present embodiment, the arrow direction in the drawing is used to indicate the path of the imaging light of the imaging device 101. Thus, the installation volume in the vehicle can be reduced by installing the diffusion screen on the surface outside the windshield.
In another possible implementation, the diffusion barrier is mounted to the roof 4 in the vehicle, as shown in fig. 5. At this time, the augmented reality display device 100 provided in the embodiment of the present application includes an imaging device 101, an image processing device 102, and a diffusion screen 103, where the imaging device 101 and the image processing device 102 are disposed at the instrument desk 1 in the vehicle, and imaging light generated by the imaging device 101 is mapped on the diffusion screen 103 to generate a real image; the real image displayed on the diffusion screen 103 is then reflected by the image processing device 102 to the windshield 2 of the vehicle and into the driver's eye 3. The diffuser screen 103 is located on the incident side of the image processing device 102, and the windshield 2 is located on the reflection side of the image processing device 102, so that the real image displayed by the diffuser screen 103 is reflected to the windshield 2 through the image processing device 102, and then enters the eyeball 3 of the driver. In the present embodiment, the arrow direction in the drawing is used to indicate the path of the imaging light of the imaging device 101. Therefore, the distance between the diffusion screen and the image processing device can be further increased, so that the object distance is increased, and an enlarged image is obtained. And meanwhile, no additional device is added on the windshield glass, so that the visual line influence on a driver is reduced.
In another possible implementation, as shown in fig. 6, the diffusion shield is mounted behind (i.e., on the side opposite to the mirror surface) the interior mirror 5. At this time, the augmented reality display device 100 provided in the embodiment of the present application includes an imaging device 101, an image processing device 102, and a diffusion screen 103, where the imaging device 101 and the image processing device 102 are disposed at the instrument desk 1 in the vehicle, and imaging light generated by the imaging device 101 is mapped on the diffusion screen 103 to generate a real image; the real image displayed on the diffusion screen 103 is then reflected by the image processing device 102 to the windshield 2 of the vehicle and into the driver's eye 3. The diffuser screen 103 is located on the incident side of the image processing device 102, and the windshield 2 is located on the reflection side of the image processing device 102, so that the real image displayed by the diffuser screen 103 is reflected to the windshield 2 through the image processing device 102, and then enters the eyeball 3 of the driver. In the present embodiment, the arrow direction in the drawing is used to indicate the path of the imaging light of the imaging device 101. This can reduce the line-of-sight impact on the driver.
In this embodiment, the diffuser screen 103 may be a holographic diffuser or a lens array.
Optionally, the imaging device 101 is located below the image processing device 102. The imaging light generated by the imaging device 101 is transmitted to the diffusion screen 103 through an optical element (reflection, refraction, or transmission) to generate the real image, that is, the imaging light generated by the imaging device 101 needs to pass through the optical element to convert the optical path, and the imaging light bypasses the image processing device 102, that is, the specific light is: the imaging device 101 generates imaging light and transmits the imaging light to the diffusion screen 103 through the optical element to generate the real image; then, the real image displayed on the diffusion screen 103 is reflected by the image processing device 102 to the windshield 2 and finally to the eyeball 3 of the driver. It is understood that there is a corresponding relationship between the positional relationship between the diffuser screen 103 and the image processing apparatus 102. That is, according to the position of the diffuser screen 103, the rotation angle of the image processing apparatus 102 needs to be adjusted accordingly, so that the image processing apparatus 102 can realize that the virtual image can accurately enter the human eyes 3 of the driver. Meanwhile, the turning angle of the image processing device 102 may also need to be adjusted according to the height, sitting posture and other conditions of different drivers. In one possible implementation, the rotation angle of the image processing apparatus 102 can be adjusted by having a lead screw nut adjustment mechanism. The screw rod nut adjusting mechanism is provided with a driving motor, a fixed screw rod and a movable nut on the fixed screw rod. The driving motor adopts a stepping motor, and can complete forward and backward rotation actions according to control keys on the vehicle. The image processing apparatus 102 has a rotation axis. The movable nut is connected with the image processing device 102 through a connecting rod. The driving motor works, the movable nut is driven to move through the fixed screw rod, the image processing device 102 is pushed or pulled by the connecting rod to change the rotating angle of the image processing device, and therefore the virtual image can accurately fall on the positions of the eyeballs 3 of the drivers at different heights.
Optionally, the image processing apparatus 102 and the windshield 2 can form an equivalent lens assembly, wherein a distance between a position of a real image displayed on the diffusion screen 103 and a center of the equivalent lens assembly is an object distance, and a distance between a position of a virtual image generated by the real image through the equivalent lens assembly and the center of the equivalent lens assembly is an image distance; in this embodiment, the virtual image size is equal to the product of the ratio of the image distance to the object distance and the real image size. That is, based on the above conditions, if the user needs to adjust the size of the image formed by the AR-HUD, the size can be obtained by adjusting the distance between the diffusion screen 103 and the equivalent lens set. In this embodiment, the size of the virtual image and the size of the real image are both used to indicate the image size. For example, as shown in fig. 7, the height of the table lamp displayed in the real image is 20 cm; if an enlarged virtual image is generated by the equivalent mirror group at this time, the height of the desk lamp displayed in the virtual image may be enlarged to 25 cm in an exemplary scheme. It is understood that other sizes of the desk lamp are enlarged in proportion to the same height, and detailed description is omitted here.
Optionally, in this embodiment, the image processing apparatus 102 may be a free-form surface mirror, an aspheric mirror, or a fresnel mirror, which can change the image display size and the imaging position. The characteristics of the image processing apparatus 102 can be obtained by optical simulation analysis according to the image source size, the virtual image imaging distance, the FOV (field angle), and the like of the diffuser screen 103. For example, when the image processing apparatus 102 is a free-form surface mirror, the surface shape, position, and rotation direction of the free-form surface mirror are obtained by optical simulation analysis based on the image source size, virtual image formation distance, FOV (field angle), and the like of the diffusion screen 103.
Alternatively, the imaging device 101 may be a Digital Light Processing (DLP) projection module or a Liquid crystal on silicon (LCoS) projection module. This DLP adopts the application of reflective digital micro mirror device, makes imaging device's total optical efficiency improve greatly, and contrast luminance homogeneity is all very outstanding to have high optical efficiency, reduce the light filling device. The LCoS has the characteristics of high light utilization efficiency, small volume, high aperture ratio and the like, and can easily realize high resolution and full color expression. Meanwhile, the size of the LCoS is generally 0.7 inch, so that the size of a related optical instrument is greatly reduced, and the volume of the imaging device is greatly reduced.
In the embodiments provided in the present application, it should be understood that the disclosed apparatus may be implemented in other manners. The above embodiments are only used for illustrating the technical solutions of the present application, and not for limiting the same; although the present application has been described in detail with reference to the foregoing embodiments, it should be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions in the embodiments of the present application.
