Among these advancements, Head-Up Display (HUD) technology, due to its unique display mode, is widely used in the automotive industry. HUDs typically project driving information (such as speed, mileage, navigation routes, and road information) from the instrument panel or center console screen onto the windshield in front of the driver, allowing the driver to focus on the road ahead without looking down at the instrument panel or center console screen, thus improving driving safety. Ensuring the display quality of the HUD is therefore crucial. Summary of the Invention

[0021] Embodiments of this disclosure will now be described in more detail with reference to the accompanying drawings. While some embodiments of this disclosure are shown in the drawings, it should be understood that this disclosure can be implemented in various forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of this disclosure. It should be understood that the accompanying drawings and embodiments of this disclosure are for illustrative purposes only and are not intended to limit the scope of protection of this disclosure.

[0022] In the description of embodiments of this disclosure, the term "comprising" and similar terms should be understood as open-ended inclusion, i.e., "including but not limited to". The term "based on" should be understood as "at least partially based on". The term "one embodiment" or "the embodiment" should be understood as "at least one embodiment". The terms "first", "second", etc., may refer to different or the same objects. Other explicit and implicit definitions may also be included below.

[0023] As mentioned above, a HUD projects driving information (such as speed, mileage, navigation route, road information, etc.) from the vehicle's instrument panel or center console screen onto the windshield in front of the driver, allowing the driver to focus on the road ahead without looking down at the instrument panel or center console screen, thereby improving driving safety. Therefore, the display quality of the HUD is crucial to the driver's experience and safety. Before the vehicle leaves the factory, the position and structure of the HUD need to be designed to provide a comfortable display for the driver. However, traditional HUD design and installation methods are often based on fixed parameters, ignoring differences in the viewing angles of different drivers and vehicle models, leading to problems such as poor display quality or installation difficulties in situations where the overall vehicle space is limited.

[0024] Therefore, embodiments of this disclosure propose a scheme for determining display information. In embodiments of this disclosure, the imaging range of the display is determined based on the user's field of view in a vehicle, wherein the imaging range is determined according to at least one of the user's eye position and virtual image position. The method further includes determining at least one of the display's mounting position and mechanical structure based on the imaging range and the imaging optical path.

[0025] This approach allows for personalized customization and flexible installation of the display, taking into account the user's field of view and the vehicle's mechanical structure. This improves display quality and installation convenience while saving development time and efficiently managing components. Furthermore, by considering the field of view of users such as drivers and passengers, it provides a comfortable viewing experience, further enhancing vehicle driving safety.

[0026] Figure 1 A schematic diagram of an example environment 100 in which various embodiments of this disclosure may be implemented is shown. For example... Figure 1 As shown, the example environment 100 includes a vehicle 110 and a cloud server 112 coupled to each other (e.g., via a network). A windshield 102 and a display 108 are deployed in the vehicle 110. The windshield 102 may be mounted at the front of the vehicle 110, and the display 108 may be located on the center console of the vehicle 110. According to embodiments of this disclosure, the vehicle 110 refers to any type of motorized or non-motorized vehicle capable of carrying people and / or goods and being movable. Figure 1 As shown, vehicle 110 is illustrated as a car. It should be understood that although vehicle 110 is... Figure 1 The image depicts a car, but this is merely exemplary and far from limited to such vehicles; examples could also include trucks, buses, motorcycles, and electric vehicles. According to embodiments of this disclosure, cloud server 112 can be any cloud server with computing power and the ability to store data.

[0027] In example environment 100, display 108 can be a head-up display (HUD) or other types of displays such as liquid crystal displays (LCDs), plasma displays, etc. The HUD can be used to project relevant information about vehicle 110 onto the windshield 102 of vehicle 110. In other embodiments, the relevant information can also be projected to other locations on the vehicle. These other locations can be within the line of sight of the driver or passenger (e.g., front passenger or rear passenger), and these locations need to include a display medium (e.g., a transparent display medium) for image display. In some embodiments, the relevant vehicle information may include, but is not limited to, status information, road information ahead, surrounding object information, navigation information, etc. The status information of vehicle 110 includes, but is not limited to, vehicle speed, mileage, remaining fuel, or battery power.

[0028] It is understandable that, in order for users such as the driver and rear passengers to be able to smoothly observe the virtual image 106 displayed on the head-up display, the cloud server 112 can receive the user's field of view sent by the vehicle 110 and determine the installation position (mounting hole position) of the head-up display based on the user's field of view. Whether the user's field of view is the driver's or the rear passenger's field of view can be determined based on the set area of ​​the head-up display. For example, if the set area of ​​the head-up display is the windshield corresponding to the driver's seat, then the user's field of view can be the driver's field of view. The vehicle 110 can determine the driver's field of view based on the position of the driver's eyes 104 in the driver's seat and the direction of the driver's gaze in a normal driving posture. For example, the vehicle 110 can use optical devices or other gaze-capturing devices to capture the driver's gaze. In some embodiments, the installation position and mechanical structure of the head-up display can also be determined by combining the internal mechanical structure of the vehicle 110 (e.g., the layout and size of components such as the dashboard and windshield) and a preset optical path design.

[0029] It should be noted that after determining the installation location and mechanical structure of the head-up display, the head-up display can be installed according to the installation location, and then debugged and verified to ensure that the virtual image displayed by the head-up display can be accurately aligned with the user's line of sight, such as the driver's, and that the image quality is clear and easy to read.

[0030] In some embodiments, the windshield 102 can reflect the imaging light received from the head-up display to the driver's eye 104. Thus, the driver's eye 104 can receive the imaging light transmitted through the windshield 102, thereby observing a magnified virtual image 106. It should be understood that the virtual image 106 is the image formed by the intersection of the backward extensions of the reflected imaging light. There is no actual object at the location of the virtual image, nor is it a convergence point of actual light rays.

[0031] The above combination Figure 1 A schematic diagram of an example environment 100 in which embodiments of the present disclosure can be implemented is described. It should be understood that environment 100 is merely illustrative and not intended to limit the scope of the present disclosure. Environment 100 may include environments not described in the diagram. Figure 1 More components are shown, and the various components in environment 100 can also be implemented in different ways.

[0032] Figure 2 A flowchart of a method 200 for determining head-up display information according to some embodiments of the present disclosure is shown. Method 200 can be... Figure 1 The vehicle 110 shown is performing the operation. Figure 2As shown in block 202, method 200 may include determining the imaging range of the display based on the user's field of view in the vehicle. The imaging range is determined according to at least one of the user's eye position and virtual image position. The user may be a vehicle occupant, such as the driver and passengers (front passenger and rear passenger). In some embodiments, the display may be a display for showing vehicle information, such as the vehicle's speed, acceleration, or battery level and fuel level. The type of display can be various, such as a head-up display or a liquid crystal display (LCD).

[0033] In some embodiments, the user's field of view can be the range that the user can see. The user's field of view is typically related to the field of view (FOV), virtual image distance (VID), and look-down angle (LDA). In some embodiments, the field of view can be the range of vision that the user can observe through the display, for example, it can be the angle between the lines connecting the two edges of the field of vision and the center of the eye. Different field of view sizes result in different amounts of information that the driver can acquire in a single viewing.

[0034] In some embodiments, the downward viewing angle refers to the angle between the user's (e.g., the driver's) line of sight when viewing the virtual image and the horizontal direction; that is, the angle between the projection light from the head-up display and the normal to the vehicle's windshield or other display medium. This angle determines the degree of tilt of the virtual image relative to the driver's line of sight and can be used to determine the height at which the image information from the head-up display should appear on the display medium, such as the windshield. The virtual image distance refers to the position of the virtual image projected by the head-up display relative to the user's eyes. The distance between the virtual image and the user can affect the user's perception and viewing comfort.

[0035] In some embodiments, the eye-point position can be the position of the user's eyes. Taking the user as a driver as an example, the eye-point position can be the coordinates of the driver's eyes, such as two-dimensional or three-dimensional coordinates. In one example, these coordinates can be (x, y, z), and the eye-point coordinates are used to characterize the starting point of the user's, such as the driver's, line of sight. Based on this, the driver's eye-point coordinates, downward viewing angle, and field of view can, to some extent, characterize the corresponding imaging range of the head-up display. That is, the imaging range is the image area displayed by the display medium corresponding to the head-up display. For example, it can be a rectangular area of ​​size m*n. The virtual image position is the position of the virtual image projected by the head-up display, which can be a point or a region. For example, the virtual image position can be the center of the virtual image or the region represented by the length and width of the virtual image.

[0036] In block 204, method 200 may include determining at least one of the following: the installation position of the display and the mechanical structure, based on the imaging range and the imaging optical path. It is understood that after determining the starting point of the user's line of sight, the tilt angle of the display, such as a head-up display, relative to the windshield (or other display medium) and the position of the light source can be determined based on geometrical optics principles (e.g., the reversibility of light, the straight-line propagation of light in a uniform medium). For example, the virtual image coordinates can be determined based on the eye-point coordinates and the lower viewing angle range, and the installation position of the head-up display can be determined based on the virtual image coordinates. The virtual image coordinates are the position coordinates of the virtual image. The virtual image coordinate system typically includes horizontal, vertical, and depth directions. By calculating the coordinate values ​​of each point on the virtual image, the shape, size, and position of the virtual image can be described. In some embodiments, the tilt angle or the position of the light source can, to some extent, characterize the position information of the head-up display (such as the position coordinates corresponding to the installation position). That is, the transmission path of the light source of the head-up display is from the light source to the user's line of sight, ensuring that the user can smoothly observe the vehicle-related information displayed on the head-up display. This process may involve multiple optical components to transmit or magnify and focus the light source.

[0037] Based on this, the imaging optical path deployed in a head-up display (HUD) can utilize several optical components to form a virtual image for projection through the propagation of light. For example, the imaging optical path can be based on optical design, with the propagation path of light pre-set so that the light can propagate along the preset path to form a clear and accurate image. In other words, the imaging optical path can be a pre-set path by the user according to actual needs. For example, the user can set a preset imaging optical path according to actual needs, including setting a suitable light source, determining the type and number of optical components, etc. The selection of the light source can consider factors such as the light intensity, emission angle, and light distribution; for example, the light source can be LED, LCD, infrared, ultraviolet, or laser. The types of optical components can include, but are not limited to, mirrors, lenses, and refractors. For example, light source parameters and optical component parameters can be input into optical design software to simulate the light path and thus simulate the preset imaging optical path. Based on this, the installation position or mechanical structure of the HUD can be determined according to the simulated preset imaging optical path and the user's input viewing angle range.

[0038] It is understandable that the mechanical structure of a head-up display (HUD) can be determined based on the imaging optical path. This mechanical structure can include the HUD's size, shape, material, and so on. Of course, the mechanical structure of the HUD can also include the structure and dimensions of components such as the HUD's mounting bracket and connecting holes. For example, the mechanical structure of the HUD can be determined based on the positions and angles of multiple optical elements included in the preset imaging optical path.

[0039] This approach allows for personalized customization and flexible installation of head-up displays (HUDs) by combining the user's field of view with the vehicle's mechanical structure. This improves display quality and installation convenience while saving development time and efficiently managing components. Furthermore, by considering the user's field of view, it provides a comfortable viewing experience for the driver, further enhancing driving safety.

[0040] In some embodiments, the imaging range of the head-up display (HUD) can be determined based on eye-point coordinates, field of view (FOV), and left-hand field of view (LDA). For example, based on the line of sight corresponding to the eye-point coordinates, a field of view extending to both sides centered on the line of sight can be determined according to the size of the FOV. This range is the imaging range of the HUD. The imaging range can be defined as the size and position of the virtual image area that the HUD system can form in the driver's field of vision. In some embodiments, based on the driver's eye-point coordinates or virtual image coordinates, it can be determined whether the virtual image projection corresponds to the real world, thereby ensuring that the information projected by the HUD accurately falls within the driver's line of sight to guarantee the display effect.

[0041] In some embodiments, the head-up display (HUD) can project vehicle-related information onto the windshield, allowing the user to observe a virtual image on the windshield and thus understand the vehicle's current status, such as current speed or battery level. It can be understood that, using the vehicle body as a coordinate system and the center of the front of the vehicle as the origin, the driver's eye-point coordinates dynamically adjust relative to the vehicle coordinate system based on the driver's height, posture, and head position. Based on this, the driver's corresponding eye-point coordinates can be determined according to the driver's physiological characteristics. For example, image detection can be performed on an image containing the driver to determine the driver's physiological characteristics. These physiological characteristics may include, but are not limited to, height, weight, age, and gender. In other embodiments, the driver's eye-point coordinates can also be determined based on the seat height, the distance between the seat and the windshield, or the seat's tilt angle.

[0042] It's understandable that head-up displays (HUDs) come in different modalities, and the imaging modes or displayed content can be different or the same for different modalities. For example, HUD types include, but are not limited to, Augmented Reality Head-up Displays (AR-HUDs), Windshield-type Head-up Displays (W-HUDs), and Combiner HUDs (C-HUDs). Different types of HUDs have different display areas or projection distances; for example, AR-HUDs have a larger imaging area and a greater projection distance. The projection distance can refer to the distance between the HUD's projection unit and the driver's eyes.

[0043] It is understandable that different projection distances can have varying impacts on the imaging effect of head-up displays and the driver's viewing experience. For example, if the projection distance is too close (e.g., less than a preset projection distance threshold), the driver needs to frequently adjust their gaze, which can easily lead to visual fatigue; if the projection distance is too far (e.g., greater than the preset projection distance threshold), it may exceed the driver's field of vision, affecting the observation effect.

[0044] In some embodiments, the HUD may include a preset imaging optical path composed of multiple optical elements. These optical elements may include, but are not limited to, mirrors, transmissive mirrors, and refractive mirrors. The relative positions of the optical elements within the preset imaging optical path can be pre-set by the user according to actual needs or application scenarios. For example, light can be reflected from optical element 1 to optical element 2, then refracted from optical element 2 to optical element 3, and finally incident on the driver's eye, allowing the driver to observe relevant vehicle information. It should be noted that the absolute position and rotation angle of the optical elements themselves are uncertain. For example, the rotation angle of the mirrors within the optical elements needs to be calculated based on the viewing angle range (FOV, VID, LDA, eye-point coordinates, virtual image coordinates, etc.) (e.g., using 3D modeling, simulation software, etc.).

[0045] Figure 3 A schematic diagram of the internal structure of a head-up display according to some embodiments of the present disclosure is shown. For example... Figure 3As shown, the head-up display 302 includes an optical engine 304 and optical components (such as mirrors A and B). The optical engine 304 and optical components can be deployed inside the head-up display 302. The optical engine 304 can be a component that generates image information related to vehicle driving information. For example, the optical engine can be an image source capable of receiving relevant vehicle signals and converting them into a visualized image. The optical components can include at least one optical element, and the type and number of optical elements are not limited herein. For example, the optical element can be a mirror, a transmission mirror, or a refraction mirror. It is understood that the optical elements can perform optical processing on the image information generated by the optical engine, such as magnification, focusing, or adjusting the projection direction, to ensure that the image is clearly projected onto the HUD display area for the driver to view. Furthermore, different optical elements have different functions.

[0046] In some embodiments, the mounting position of the head-up display (HUD) on the vehicle bracket can be determined based on the HUD's imaging range. The imaging range can be determined based on the user's viewing angle. In one example, driver A, sitting in the driver's seat, has a relatively comfortable viewing area of ​​m*n rectangular region on the windshield or other display medium. This area can, to some extent, reflect the size and position of the HUD's virtual image area. Figure 3 As shown, after determining the imaging range (virtual image area) and eye-point coordinates, the installation position of the head-up display (HUD) can be determined. For example, the upper limit height of the virtual image can be determined based on the driver's line of sight. The upper limit height can refer to the highest point the driver's line of sight can reach when viewing the virtual image. Based on this upper limit height and the tilt angle of the windshield, the tilt angle between the reflector 2 and the windshield can be determined. The installation position of the HUD can then be determined based on the tilt angle between the reflector 2 and the windshield.

[0047] In practical applications, different modal heads-up displays (HUDs) employ different imaging modes and form virtual images in different ways. For example, AR-HUDs typically have a horizontal field of view (FOV) greater than 10 degrees and a vertical FOV greater than 3 degrees, meeting the needs of augmented reality displays. W-HUDs, on the other hand, generally only consider the horizontal FOV, which is usually smaller, around 5 degrees. AR-HUDs typically have a VID (visible area index) of over 10 meters, while W-HUDs typically have a VID of around 2.5 meters. Therefore, different imaging modalities of HUDs correspond to different imaging ranges, which also implies differences in installation location and mechanical mechanisms. Based on this, different modal heads-up displays correspond to different virtual image modes (e.g., virtual image mode 1, virtual image mode 2), and the upper limit height of the virtual image corresponding to different virtual image modes is also different. Therefore, the installation location of different modal heads-up displays can be determined based on the upper limit height of the virtual image corresponding to each modal. For example, as... Figure 3As shown, the installation position for W-HUD is installation position 1, and the installation position for AR-HUD is installation position 2.

[0048] In this way, for HUDs with multiple imaging modes, the corresponding upper limit position of the imaging can be determined according to the specific imaging mode, thereby determining the installation position of the HUD.

[0049] like Figure 3 As shown, the preset imaging optical path can be the optical engine - reflector B - reflector A - windshield - virtual image - human eye. To allow the driver to observe the vehicle's current status through the windshield, the rotation angle of reflector A or reflector B can be adjusted so that the light from the optical engine can reach the human eye smoothly through reflections from reflectors A and B and the windshield. In some embodiments, the rotation angle of reflector A or reflector B can be determined using an optical simulation algorithm. Alternatively, the rotation angle of reflector A or reflector B can be adjusted using a stepper motor. For example, based on the driver's field of view, a stepper motor or other driving device can be used to drive reflector A or reflector B to adjust its rotation angle. For instance, software can be used to fine-tune the rotation angle of the reflection module using a stepper motor, thereby changing the reflection position of the external optical path of the head-up display on the windshield until the reflection position of the external optical path of the head-up display on the windshield is within the driver's field of view.

[0050] like Figure 3 As shown, after determining the mounting positions of the optical components and the optical engine 304, the shape of the head-up display (HUD) can be determined based on their positions. For example, the shape of the HUD can be determined by drawing a bounding box. The bounding box can be a regular shape such as a rectangle, trapezoid, or circle, or it can be an irregular shape. For example, the shape 302 of the HUD can be drawn based on the actual mounting positions of the optical components and the optical engine 304. As described above, the bounding box used to surround the reflection module and the optical engine can be determined using 3D modeling or simulation software to ensure that the size of the HUD can accommodate the layout and installation requirements of its internal components.

[0051] Further reference Figure 3 The optical engine 304 can project imaging light related to driving information, then reflect the imaging light through mirror B to mirror A, and finally mirror A emits the received imaging light into the windshield to form a virtual image within the driver's field of vision, so that the driver can observe the display effect of the head-up display.

[0052] In this way, the optical display effect design of head-up displays with different imaging modalities can be met, the size requirement of the head-up display is small, thus enabling one device to serve multiple purposes and providing more layout possibilities in the vehicle space.

[0053] Figure 4 This diagram illustrates the mounting positions of different modal heads-up displays (HUDs) according to some embodiments of the present disclosure. As described above, HUDs are divided into different modalities, and the imaging modes or display content corresponding to different modal HUDs can be different or the same. Therefore, based on the imaging range of different modal HUDs, the mounting position of the HUD on the vehicle bracket, i.e., the mounting hole position, can be determined. For example, the mounting hole positions corresponding to W-HUD and AR-HUD. Figure 4 As shown, both W and AR modes of display can be achieved. That is, before the vehicle leaves the factory, different mounting hole positions can be pre-set for different modes of head-up displays according to their modes, so that users can choose the appropriate head-up display to install in the corresponding hole position according to their actual needs.

[0054] In practical applications, strong sunlight or other light sources can cause glare, interfering with the driver's vision and increasing driving risks. Therefore, to ensure the display effect of the head-up display (HUD) and prevent ambient light from reflecting into the eyes, thus meeting the glare-free requirement, the shape or structure of the HUD can be specially designed. For example, the top cover of the HUD can be made curved.

[0055] Figure 5 A schematic diagram showing the shape of a head-up display according to some embodiments of the present disclosure is illustrated. Figure 5 As shown, the top cover of the head-up display can be made into a curved shape to ensure that ambient light does not reflect into the driver's eyes. In other embodiments, glare problems can also be avoided by adjusting the materials and finishes of the head-up display. For example, the housing of the head-up display can be made of special optical materials or coatings to further reduce the impact of glare on the driver.

[0056] In this way, the anti-glare design ensures clear display of driving information, improving driving safety.

[0057] Furthermore, based on the interface or communication protocol between the head-up display (HUD) and the vehicle, the vehicle's status and driving information (such as speed, mileage, navigation route, road information, etc.) can be obtained and displayed on the windshield using the HUD. This step can be accomplished through underlying software configuration, improving the practicality and convenience of the HUD.

[0058] It should be noted that the methods for determining head-up display information provided in some embodiments of this specification are applicable not only to vehicle driving scenarios, but also to interactive game scenarios, office scenarios, virtual reality scenarios, augmented reality scenarios, etc.

[0059] Figure 6 A schematic diagram of another internal structure of a head-up display according to some embodiments of the present disclosure is shown. For example... Figure 6 As shown, the head-up display 600 includes a bounding frame 602, an optical engine 604, and optical components. The optical engine 604 and optical components are located inside the bounding frame 602. The optical components may include a reflection module and diaphragms. The reflection module may include mirror A, mirror B, or multiple mirrors, and the diaphragms may include diaphragm a, diaphragm b, or multiple diaphragms. Mirrors A and B can be curved mirrors or flat mirrors. Diaphragm a is mounted in front of mirror A, and diaphragm b is mounted in front of mirror B. Adding diaphragms in front of the reflection module can correct chromatic aberration and improve imaging resolution. In this way, aberrations can be corrected, thereby further improving image quality.

[0060] Figure 7 A schematic diagram of another internal structure of a head-up display according to some embodiments of the present disclosure is shown. For example... Figure 7 As shown, the head-up display 700 includes a bezel 702, an optical engine 704, and optical components. The optical engine 704 and optical components are located inside the bezel 702. The optical components may include a reflection module. Alternatively, if the mounting position and mechanical structure of the head-up display are fixed, a larger projection light path can be constructed to achieve different modal optical display effects using the same head-up display structure.
