Detailed Description

Referring to FIG. 1, a schematic diagram of an imaging system comprising a HUD100 and a windshield 102 of a vehicle is shown. Light rays emitted by the HUD100 are incident on the windshield 102 and are reflected on the windshield 102, and the reflected light rays converge on the observation area of the observer, so that the observer can observe a virtual image outside the windshield in the observation area.

Referring to the schematic structural diagram of the HUD shown in fig. 2, the HUD100 includes: image source 200, planar mirror 202, and curved mirror 204. The image source 200, the planar mirror 202 and the curved mirror 204 are fixed in the HUD by a mount, respectively. The light emitted from the image source 200 is reflected by the plane mirror 202 and then enters the curved mirror 204, and is reflected by the curved mirror 204 and then exits from the light exit of the HUD, and the exiting light enters the windshield of the vehicle.

The image source 200 may be an active light-emitting image source or a passive light-emitting image source.

In one embodiment, active light-emitting image sources, include, but are not limited to: light Emitting Diode (LED) displays and Organic Light-Emitting Diode (OLED) displays.

The passive light-emitting image sources include, but are not limited to: liquid Crystal Displays (LCDs), DLP projection (DLP), and projectors.

The plane mirror 202 can make light go through the primary reflection back incidence curved mirror in the HUD, increases the optical path of light in the HUD, reduces the volume of HUD.

The curved mirror 204 can be matched with the shape of a windshield to eliminate the distortion of images presented by light; and the image is amplified, and the size of the image displayed by the light is increased.

The exit surface of the plane mirror is arranged opposite to the exit surface of the curved mirror and the image source light-emitting surface at the same time; the emergent surface of the plane mirror is the surface of the plane mirror for reflecting light; specifically, light from the image source may be reflected by a flat mirror and then reflected by a curved mirror.

Or the emergent surface of the curved mirror is arranged opposite to the emergent surface of the plane mirror and the emergent surface of the image source; the emergent surface of the plane mirror is the surface of the plane mirror for reflecting light; specifically, light emitted from the image source may be reflected by the curved mirror and then reflected by the flat mirror.

At present, the HUD technique can avoid the driver to look at the distraction that the panel board leads to driving the in-process head-lowering, improves driving safety factor, also can bring better driving experience simultaneously. Therefore, a large screen full-size HUD that uses an automobile windshield for imaging is receiving increasing attention.

The AR-HUD reasonably and vividly displays some driving information in a sight line area of a driver through an internal specially designed optical system so as to enhance the perception of the driver to the actual driving environment. For example, when the driver drives the vehicle to deviate from a given lane, the AR-HUD may mark a red line at the edge of the lane line of the normal driving lane of the vehicle to remind the driver that the vehicle has deviated from the lane; and a bright band of a mark can be seen at the rear of the front vehicle when driving. Therefore, the rise of AR-HUD puts higher technical requirements on the HUD industry.

Based on the principle of AR-HUD, images projected by the AR-HUD need to be perfectly fused with objects in a real environment, such as direction indication arrows need to be precisely fused with roads, and good visual perception can be provided for observers.

In the process of observing the image presented by the AR-HUD, the situation that the image presented by the AR-HUD and the real environment which are seen by the observer have vertical parallax can occur, the vertical parallax can cause that the image seen by the observer and the real environment cannot be completely fused together in the vertical direction, and the use experience of the observer on the AR-HUD is reduced.

The vertical direction refers to a direction perpendicular to a plane on which a road surface on which the vehicle runs is located.

The vertical parallax is a case where an image presented by the HUD viewed by the observer is vertically displaced.

Further, when the image is an AR-HUD rendered image, the vertical parallax refers to a situation where the image and the real environment cannot be completely fused together in the vertical direction.

Referring to the schematic diagram of fig. 3a showing the HUD forming a vertical parallax, the light emitted from the HUD100, through the light-emitting position a, is reflected on the windshield 102, and the reverse extension line of the reflected light passes through the virtual image position a' of the light-emitting position a relative to the windshield.

Normally, observation area one 1 is set as the default observation area of the HUD, but since there are differences in height between different observers, the sitting posture is different even if they are sitting at the same position. Therefore, in the vertical direction, two different observation regions, observation region two 2 and observation region three 3, appear also for different observers.

When the two eyes of the observer are vertically higher, that is, in the observation area two 2 in the figure, it can be seen from the above description that the reverse extension lines of the reflected light rays must pass through a', and it can be seen that the image at the virtual image position two 5 seen by the observer at this time is located lower than the image position at the virtual image position one 4. Similarly, when the positions of both eyes of the observer are lower in the vertical direction, that is, in the observation region three 3 in fig. 3, the image position of the virtual image position three 6 seen by the observer in the observation region three 3 at this time is located higher than the image position of the virtual image position one 1.

That is, when both eyes of the observer are positioned in observation region two 2, since the downward viewing angle is larger than when both eyes of the observer are positioned in observation region one 1, vertical parallax occurs in which the image position is shifted downward when the observer observes the image at virtual image position two 5. When both eyes of the observer are positioned in the observation area three 3, since the downward viewing angle is smaller than when both eyes of the observer are positioned in the observation area one 1, a vertical parallax in which the image position is shifted upward occurs when the observer observes the image at the virtual image position three 6.

Further, referring to fig. 3B, when the AR-HUD rendering image is fused with the real scene in the real environment, the image and the real scene cannot be fused, and a schematic diagram of vertical parallax is formed, where an observation area one 1 is set as a default observation area of the AR-HUD, and then the observer sees that the image at a virtual image position one 4 in the observation area one 1 is perfectly fused with the real scene B in the real environment. Therefore, the observer can see an image perfectly blended with the real scene B in the real environment at the virtual image position one 4 with both eyes within the observation area one 1 of the AR-HUD.

However, when both eyes of the observer are positioned in the observation region two 2, since the downward viewing angle is larger than when both eyes of the observer are positioned in the observation region one 1, vertical parallax occurs due to a case where the image is positioned below the real scene B in the real environment when the observer observes the image at the virtual image position two 5. When the two eyes of the observer are located in the observation area three 3, since the downward viewing angle is smaller than when the two eyes of the observer are located in the observation area one 1, vertical parallax occurs due to a case where the image is located above the real scene B in the real environment when the observer observes the image at the virtual image position three 6.

The lower visual angle is an included angle between a connecting line between eyes of an observer and the center of the HUD image and a plane where the vehicle driving direction is located.

Based on this, this application embodiment provides a new line display device, imaging system and vehicle, through control curved mirror moving mechanism removal curved mirror to control level crossing moving mechanism removes the level crossing, changes incident position and/or incident angle when HUD sends the windshield of light incident vehicle, with adjust in the vertical direction HUD's formation of image position compares with the condition that the observer has vertical parallax when watching the image that HUD presented in the correlation technique, adjusts HUD's formation of image position in the vertical direction, thereby has eliminated the vertical parallax that the observer exists when watching the image that HUD presented, avoids influencing observer's sight angle at the vertical direction, has improved HUD's use experience.

In order to make the aforementioned objects, features and advantages of the present application more comprehensible, the present application is described in further detail with reference to the accompanying drawings and the detailed description.

In the following embodiments, the term "HUD" may refer to a head-up display device that emits an image with an augmented reality effect, and may also refer to a general HUD.

The term "visually fused with the real environment" means that the image of the HUD presentation seen by the two eyes of the viewer is completely fused with the real environment.

The eye box refers to the area where the viewer can see the complete image of the HUD. For AR-HUD, an image that blends well with the real environment can be observed in the eye box.

The center position of the eye box refers to the position of the geometric center of the eye box.

The eye ellipses are a statistical representation method for describing the positions of the eyes of drivers with different statures relative to reference points in the vehicle in space, and are divided into 90 percent, 95 percent, 99 percent and other eye ellipses according to the distribution condition of the eyes.

Generally, the eye box coincides with or partially overlaps with the eye ellipse region, and when the two eyes of the observer are within the eye ellipse region, the image of the HUD can be observed; when the two eyes of the observer are in the eye box, the complete image of the HUD can be observed; for AR-HUD, an image with better fusion effect with the real scene can be observed; when the two eyes of the observer are positioned at the center of the eye box, the image perfectly fused with the real scene can be observed.

In addition to the above-mentioned rotating device, referring to the schematic diagram of the internal structure of the HUD shown in fig. 4b when the curved mirror moving mechanism and the plane mirror moving mechanism both adopt the translating device, in order to translate the curved mirror and the image source, the curved mirror moving mechanism and the plane mirror moving mechanism include: and a translation device.

The translation device comprises: a driving unit 502, a first transmission member 500 and a second transmission member 504.

The driving unit 502 is connected to the first transmission member 500, the first transmission member 500 is disposed on the driving unit 502 and is in transmission connection with the meshing teeth of the second transmission member 504, and the second transmission member 504 is connected to the curved mirror or the flat mirror.

The driving unit drives the first transmission piece to rotate; when the first transmission piece rotates, the second transmission piece is driven to translate; the curved mirror or the plane mirror is in the second driving medium drives down along the extending direction translation of the meshing tooth of second driving medium, makes in the HUD curved mirror or the image source is close to or keeps away from windshield, thereby changes incident angle and/or incident position when the HUD sends light and incides the windshield of vehicle.

The extending direction of the engaging teeth of the second transmission member may include, but is not limited to: horizontal direction, vertical direction, and oblique direction. Therefore, the curved mirror or the plane mirror can be driven by the second transmission piece to move along: the horizontal direction, the vertical direction, or the oblique direction approaches or moves away from the windshield, thereby changing the angle of incidence at which the light emitted from the HUD is incident on the windshield of the vehicle.

The curved mirror or the image source is close to the windshield, and the vertical distance from any point on the curved mirror or any point on the image source to the plane of the windshield is shortened. The curved mirror or the image source is far away from the windshield, and the vertical distance from any point on the curved mirror or any point on the image source to the plane of the windshield is increased.

The vertical distance specifically refers to a vertical distance between any one point and a plane where the windshield is located. HUD's inner structure except curved mirror moving mechanism with level crossing moving mechanism all adopts rotary device and curved mirror moving mechanism with level crossing moving mechanism all adopts the translation device outside, can also have as shown in fig. 4c curved mirror moving mechanism adopts rotary device just HUD's inner structure schematic when level crossing moving mechanism adopts the translation device and as shown in fig. 4d curved mirror moving mechanism adopts the translation device just HUD's inner structure schematic when level crossing moving mechanism adopts rotary device.

HUD's inner structure except curved mirror moving mechanism with level crossing moving mechanism all adopts rotary device and curved mirror moving mechanism with level crossing moving mechanism all adopts the translation device outside, can also have as shown in fig. 4c curved mirror moving mechanism adopts rotary device just HUD's inner structure schematic when level crossing moving mechanism adopts the translation device and as shown in fig. 4d curved mirror moving mechanism adopts the translation device just HUD's inner structure schematic when level crossing moving mechanism adopts rotary device.

Alternatively, in another embodiment, refer to fig. 5a, fig. 5b, fig. 5c, fig. 5d, fig. 5c, fig. 5d, fig. 5a, fig. 5b, fig. 5c, fig. 5d, fig. 5c, fig. 5d, fig. 5c, fig. 5d, fig. 4, fig. 1, fig. 2, fig. 4, fig.; can only set up in HUD curved mirror moving mechanism or level crossing moving mechanism, through setting up curved mirror moving mechanism rotates or the translation to the curved mirror, perhaps through setting up level crossing moving mechanism rotates or the translation to the level crossing, in order to reach the messenger in the HUD curved mirror or the purpose that the image source is close or keeps away from windshield, thereby changes incident position and/or incident angle when HUD sends light and incides the windshield of vehicle.

In addition to using the above-mentioned rotating device and the above-mentioned translating device, the side length (i.e. the side length on the horizontal section) width of the light outlet of the HUD along the traveling direction of the vehicle in the section in the traveling direction of the vehicle can be increased, see the internal structure diagram of the HUD in which the curved mirror moving mechanism and the plane mirror moving mechanism both use rotating mechanisms, as shown in fig. 4a, and the range of the side length L of the HUD along the traveling direction of the vehicle is expanded to 180 mm to 260 mm, or adjusted to be smaller or larger according to the actual vehicle condition, so as to increase the coverage of the eye box in the vertical direction and reduce the probability of the occurrence of vertical parallax.

The eye box refers to a region where a viewer can observe the complete image of the HUD. For AR-HUD, an image that blends well with the real environment can be observed in the eye box.

When the HUD is an AR-HUD, in addition to the problem of vertical parallax occurring in the vertical direction, there is also a problem that horizontal parallax exists between the observed image and the real environment due to horizontal shift of the left and right eyes and both eyes in the horizontal direction of the observer in the process of viewing the AR-HUD display image by the observer in the vehicle.

In order to solve the above problem, the image source 200 in the HUD may be disposed at a position close to the focal plane of the curved mirror 204 or at a position where the focal plane of the curved mirror 204 is located, so that the light reflected out of the HUD can form a remote virtual image.

The remote virtual image is used for eliminating horizontal parallax when an observer watches the image.

The imaging position of the remote virtual image may be a position that is ten meters, several tens of meters, or infinity from the observer.

The imaging position of the remote virtual image is related to the real environment, so that the remote virtual image is visually fused with the real environment as much as possible, and the horizontal parallax generated when a driver observes AR-HUD imaging is avoided as much as possible.

In summary, the head-up display device proposed in this embodiment moves the curved mirror by controlling the curved mirror moving mechanism, and controls the plane mirror moving mechanism to move the plane mirror, so as to change the incident position and/or incident angle when the HUD emits light to enter the windshield of the vehicle, and adjust the imaging position of the HUD in the vertical direction. Especially when applied to AR-HUD, the observer can see the image presented by the HUD in the adjusted imaging position to be visually fused with the real environment, so that the excellent visual experience is brought.

The image capturing apparatus 600 and the HUD100 are connected to the ECU, respectively.

The image capture apparatus 600 is mounted on a windshield of a vehicle, and is configured to capture an image of an observer in the vehicle and transmit the captured image to the ECU.

And the ECU is used for sending a control command to the HUD to enable the curved mirror and the plane mirror in the HUD to move, and the imaging position of the HUD is adjusted in the vertical direction.

When the HUD adopts AR-HUD, the image which is seen by the observer and presented at the adjusted imaging position is visually fused with the real environment, and the vertical parallax when the observer watches the image is eliminated.

The ECU can adopt any instruction that can control mechanical equipment in the prior art, and send to the HUD to control curved mirror and plane mirror in the HUD move, and specific process here is no longer repeated.

In the head-up display imaging system shown in fig. 6, the HUD using the rotating device for the curved mirror moving mechanism and the plane mirror moving mechanism is only illustrated, and the head-up display imaging system may also use any HUD structure given in embodiment 1, which is not repeated in this embodiment.

The embodiment also provides a vehicle comprising the head-up display imaging system.

Especially when applied to AR-HUD, the observer can see the image presented by the HUD in the adjusted imaging position to be visually fused with the real environment, so that the excellent visual experience is brought.
