[0002] With the improvement of automobile safety and driving convenience, the head-up display system (HUD) has gradually become an important configuration in modern cars. HUD projects key driving information onto the windshield in front of the driver, allowing the driver to obtain information such as speed, navigation, and warning signals without taking his eyes off the road, thereby improving driving safety and comfort.

[0003] However, the accuracy of the HUD system and the user experience largely depend on the alignment of the HUD image with the driver's eye point. Eye point position determination is a key step in the design and debugging of the HUD system. In existing technologies, eye point position determination usually relies on complex measurement equipment and cumbersome debugging processes. These methods are not only time-consuming and costly, but also particularly difficult for non-production line environments, such as outdoor environments of real vehicles or non-production line environments. Summary of the invention

[0007] The disclosed embodiments provide an eyepoint position determination device and system; through the coordinated work of the calibration unit and the leveling unit, the eyepoint position is accurately located in three dimensions (length, width and height), thereby improving the accuracy and reliability of the HUD system. The design of the device allows for quick setup and adjustment inside the vehicle without the need for complex measuring tools or disassembly of vehicle components, thus simplifying the process of determining the eyepoint position.

It should be noted that Figure 1 Only a portion of the in-vehicle system 100 is shown, not all of the components of the in-vehicle system 100 .

[0025] exist Figure 1In the navigation subsystem 110, a positioning component 111 and a map information storage device 112 are included.

These devices that can communicate with the vehicle-mounted communication device 121 can be other vehicles, roadside machines or roadside stations, or mobile terminal devices used by people in the vehicle. In some examples, the vehicle-mounted communication device 121 can use 3G cellular communication, such as code division multiple access (code division multiple access, CDMA), EVDO, global system for mobile communications (global system for mobile communications, GSM) / general packet radio service technology (general packet radio service, GPRS), or 4G cellular communication, such as long term evolution (long term evolution, LTE), or 5G cellular communication.

[0028] The radar 122 is used to sense objects in the surrounding environment of the vehicle, and can also be used to sense the speed and / or direction of these objects. In some examples, the radar 122 can use electromagnetic waves or lasers as a medium to detect objects based on a time of flight (TOF) method or a phase-shift method, and detect the position of the detected object, the distance to the detected object, and the relative speed. In some examples, in order to be able to detect objects located in front of, behind, or to the side of the vehicle, the radar 122 can be configured at an appropriate position outside the vehicle.

[0029] The laser rangefinder 123 may utilize laser light to sense objects in the environment in which the host vehicle is located. In some embodiments, the laser rangefinder 123 may include one or more laser sources, a laser scanner, and one or more detectors, among other system components.

[0030] The camera 124 can be used to capture multiple images of the surrounding environment of the vehicle. The camera 124 can be a static camera or a video camera. In some examples, in order to obtain the external image of the vehicle, the camera 124 can be located at an appropriate position outside the vehicle. For example, in order to obtain the image in front of the vehicle, the camera 124 can be configured in the interior of the vehicle close to the front windshield. Alternatively, the camera 124 can be configured around the front bumper or radiator grille. In some examples, in order to obtain the image behind the vehicle, the camera 124 can be configured in the interior of the vehicle close to the rear window glass. Alternatively, the camera 124 can be configured around the rear bumper, trunk or tailgate. In some examples, in order to obtain the image of the side of the vehicle, the camera 124 can be configured in the interior of the vehicle close to at least one of the side windows. Alternatively, the camera 124 can be configured around the side mirrors, fenders or doors.

[0031] exist Figure 1 In the embodiment, the vehicle driving state detection device group 130 may include: a steering angle sensor 131 for detecting the steering angle of the vehicle, a vehicle speed sensor 132 for detecting the driving speed of the vehicle, and an acceleration sensor 133 for detecting the acceleration applied to the vehicle. In some examples, as shown in the dotted box, an inertial sensor 134 for detecting the position and orientation change of the vehicle based on inertial acceleration may also be included. The inertial sensor 134 may be a combination of the acceleration sensor 133 and a gyroscope in a specific implementation process.

[0032] exist Figure 1In the embodiment, the data processing unit 140 can be implemented as a computing system having a memory, a processor, an input / output interface, and a bus connected to these. In some examples, the data processing unit 140 causes the processor to execute multiple commands through program instructions stored in the memory to process the data obtained by the navigation subsystem 110, the environment detection device group 120, and the vehicle driving state detection device group 130. In some examples, the data processing unit 140 can also partially or completely control the driving of the vehicle based on the processed data.

[0033] exist Figure 1 The display control unit 150 is used to control multiple display units 160. The display control unit 150 can be used to transmit images to the display unit for display. The display unit 160 can be a display screen, projection equipment, etc. inside the vehicle, or it can be a display screen of a HUD display device in the vehicle, such as a windshield.

[0034] exist Figure 1 In the embodiment, the data processing unit 140, the display control unit 150 and the display unit 160 can be used as the main body of the head-up display (HUD) device. The display control unit 150 can process the received data processed by the data processing unit 140, or after receiving the data obtained by the navigation subsystem 110, the environment detection device group 120 and the vehicle driving state detection device group 130, to obtain the display information to be displayed, and project the display information onto the windshield of the vehicle through the display unit 160 for display.

[0035] The Head Up Display (HUD) device projects the light of the display image output by the image source onto an imaging window (e.g., an imaging board, a windshield, etc.) through, for example, a reflective optical design, so as to display vehicle status information such as vehicle speed and fuel level, as well as indication information such as navigation and hazard warnings, at an appropriate position in front of the driver. This allows the driver to obtain relevant information such as vehicle speed and fuel level without shifting his line of sight away from the road ahead, thereby improving the driving safety factor and driving experience.

[0036] Specifically, refer to Figure 2 and Figure 3 The head-up display device can be arranged on a vehicle, and the vehicle includes a windshield 204 located at the front of the vehicle. The driver and passengers in the vehicle cabin 208 can see the front of the vehicle through the windshield 204.

[0037] exist Figure 3In the embodiment of the present invention, the windshield 204 is visually located above the vehicle dashboard 206. The driver can turn the steering wheel 210 in the passenger cabin 208 to steer the vehicle, such as changing lanes, merging and parking the vehicle. In some embodiments, the steering wheel 210 can be retracted or omitted.

[0038] The HUD system is designed to provide a way to view critical driving information without having to lower the head. To achieve this, the HUD image needs to be projected precisely at the driver's eye point, which is the spatial location where the driver's eyes are located.

[0039] The accuracy of the point position directly affects the viewing effect of the HUD image. If the eye point position is inaccurate, it may cause image ghosting, deformation, and even affect the driver's vision and driving safety.

[0040] Traditional HUD eye point positioning methods rely on complex measurement equipment and tedious debugging processes. These methods are not only time-consuming and costly, but also difficult to confirm HUD eye points in non-production line environments, such as outdoor environments of real cars or non-production line environments.

[0041] In an actual vehicle environment, the HUD image may be distorted due to installation tolerances and differences in components such as windshields. Without a specific production line, it is difficult to process and collect HUD images, and subsequent data processing and image analysis are impossible. Existing methods usually require removing the driver's seat, using a tape measure or other measuring tools for simple measurements, and then fixing the captured image with a camera at the theoretical eye point. Due to the error of the measuring tool and the manual search for the measurement reference, this method has a large deviation in the positioning of the theoretical eye point, resulting in a large deviation between the collected data and the theoretical data, affecting the acquisition accuracy.

[0042] Based on this, the present disclosure first provides an eye point position determination device, Figure 4 It is shown that the eye point position determination device may include a calibration unit 1 and a leveling unit 2, wherein the calibration unit 1 is arranged at a first set height relative to the vehicle floor inside the above-mentioned vehicle, and the leveling unit 2 is arranged at a second set height relative to the vehicle floor inside the vehicle. The first set height and the second set height are equal within a threshold range, wherein the above threshold range may be 2 cm, 5 cm, etc., or the ratio of the difference between the first set height and the second set height may be less than 10%, 5%, etc., and may also be customized according to user needs, which will not be described in detail in this example implementation.

[0043] The calibration part 1 is provided with a positioning mark, and the positioning mark can be used by the positioning component 11 to determine the position of the eye point in the length and / or width direction of the vehicle according to the positioning mark.

[0044] In some examples, the above-mentioned calibration unit 1 can be located on the optical path between the position of the HUD imaging and the approximate position of the eye point, that is, the above-mentioned calibration unit 1 can be arranged between the headrest of the driver's seat and the HUD imaging position. Specifically, the calibration unit 1 can be arranged at a set position. The set position is at a first set height from the vehicle floor, and the positions from the driver's side window glass and from the vehicle windshield can be set according to different vehicles. Specific data are not elaborated in this example. The setting of the specific position can make the calibration unit 1 located between the set position of the eye point and the HUD display area.

[0045] Optionally, the above-mentioned calibration unit 1 can be a calibration plate. Refer to Figure 5 , the calibration plate can include a positioning image. The positioning image can be composed of multiple straight lines, or in the shape of a "field" character, or can be customized according to user needs, which is not elaborated in the implementation manner of this example.

[0046] Optionally, the above-mentioned positioning mark can also be a circle, a square or other shapes, which are not specifically limited in this example.

[0047] In some examples, when the positioning mark on the above-mentioned calibration unit 1 is a positioning image, the above-mentioned positioning component 11 can be an imaging device. The imaging device captures the acquisition image of the above-mentioned positioning image, and determines the position of the eye point in the width direction of the vehicle by comparing the acquisition image with the positioning image. Further, the pitch angle of the above-mentioned imaging device can also be determined according to the comparison between the acquisition image and the positioning image, that is, the observation pitch angle at the position of the eye point.

[0048] For example, refer to Figure 6 , if the acquisition image is shifted to the left compared with the positioning image, the position of the eye point is in the azimuth on the right side of the above-mentioned positioning component 11. Refer to Figure 7 , if the acquisition image is shifted to the right compared with the positioning image, the position of the eye point is in the position on the left side of the above-mentioned positioning component 11. Adjust the position of the above-mentioned positioning component 11 until the acquisition image obtained by the above-mentioned positioning component 11 is aligned with the above-mentioned positioning image, then define the position of the positioning component 11 in the width direction as the position of the eye point in the vehicle width direction.

[0049] Continue to refer to Figure 7 , the position of the eye point will also shift upward. After determining the position in the height direction according to the above-mentioned leveling unit 2, the upward shift of the position of the eye point is determined by the pitch angle of the imaging device. Therefore, the pitch angle of the above-mentioned imaging device can be adjusted to determine the optical path direction of the position of the eye point.

[0050] It should be noted that, refer to Figure 8, the width direction is the direction of the Y axis of the vehicle in the vehicle coordinate system, the length direction is the direction of the X axis in the vehicle coordinate system, and the height direction is the direction of the Z axis of the vehicle in the vehicle coordinate system.

[0051] In some examples, the positioning component 11 may also include a laser emitter and an angle measuring device (not shown). In this case, the positioning mark may be a circle or a black dot, etc. The laser emitter may be used to emit a laser to illuminate the positioning mark. When irradiating the positioning mark, the angle between the laser and the width direction of the vehicle may be measured by an angle measuring device. Then, the position of the vehicle in the width direction may be determined based on the angle. Specifically, when the angle is within a preset range of 90 degrees, the position of the positioning component 11 in the width direction of the vehicle is determined as the position of the eye point in the width direction.

[0052] In some examples, reference Fig. 9 The eye point position determination device may further include a mounting plate 3 and a fixing portion 4. The mounting plate 3 may be a rectangular plate structure including a first end and a second end. The first end and the second end are respectively ends where the short sides of the rectangle are located. The mounting portion is used to fix the calibration portion 1 and the leveling portion 2.

[0053] In some examples, the number of the calibration unit 1 may be one, see Fig.10 When there is only one calibration part 1, the calibration part 1 is fixed to the first end of the mounting plate 3, and the leveling part 2 is mounted to the second end, which can improve the stability of the eye point position determination device.

[0054] The number of the calibration parts 1 can also be two, see Fig.11 , respectively arranged at the first end and the second end of the above-mentioned mounting plate 3, and the above-mentioned leveling portion 2 is installed in the middle position of the above-mentioned mounting plate 3, which can improve the stability of the eye point position determination device, and at the same time, enable the above-mentioned eye point position determination device to adapt to different vehicles, left-hand drive or right-hand drive.

[0055] The fixing part 4 is connected to the mounting plate 3 and is used to fix the mounting plate 3 in the vehicle. When the fixing part 4 fixes the mounting plate 3 in the vehicle, the calibration part 1 can be fixed above the main driving position of the vehicle and at a first set height position from the bottom plate of the vehicle.

[0056] In some examples, the fixing portion 4 may be a clamping mechanism, which is disposed on both sides of the mounting plate 3, and the mounting plate 3 is fixed to a sun visor of the vehicle by the clamping mechanism. When the eye point position determination device is clamped on the sun visor, the sun visor is in a position perpendicular to the vehicle floor.

[0057] In some examples, the leveling unit 2 is used to emit light for the positioning component 11 to perform optical path alignment to determine the position of the eye point in the length and height directions of the vehicle. Specifically, the light emitted by the leveling unit 2 is irradiated to the set position, the position of the positioning component 11 is moved, and when the positioning component 11 is irradiated by the light emitted by the leveling unit 2, the position of the positioning component 11 in the height and length directions of the vehicle is determined as the position of the eye point in the height and length directions.

[0058] Optionally, the light emitted by the leveling part 2 may be a laser, which can perform better positioning.

[0059] In some examples, reference Fig.11 The leveling part 2 may include a light-emitting structure 22 and a leveling structure 21, wherein the leveling structure 21 may include at least two leveling mechanisms, and the leveling mechanism may include a fixing plate and a leveling plate, wherein the fixing plate may be fixed to the above-mentioned mounting plate 3 by bolts, the fixing plate is arranged parallel to the mounting plate 3, the leveling plate is vertically connected to the fixing plate, and the fixing plates of two adjacent leveling mechanisms are respectively arranged on both sides of the mounting plate 3, and the above-mentioned leveling part 2 is installed between the two leveling plates, and the two leveling plates cooperate with each other so that the light emitted by the above-mentioned light-emitting structure 22 can be in a direction parallel to the base plate.

[0060] In some examples, the leveling part 2 may also be a leveling device such as a spirit level, which will not be described in detail in this example implementation.

[0061] In some examples, reference Fig.12 The mounting plate 3 may also be provided with a reinforcing structure 5 for increasing the strength of the mounting plate 3. The reinforcing structure 5 can reduce the thickness and mass of the mounting plate 3 while ensuring the strength of the mounting plate 3, thereby reducing the difficulty of fixing the mounting plate 3 in the vehicle.

[0062] It should be noted that the calibration part 1, the leveling part 2 and the mounting plate 3 can be connected by bolts, or by methods such as strong glue, magnetic attraction, etc., which will not be described in detail in this example implementation.

[0063] The eye point position determination device provided in the embodiment of the present disclosure quickly and accurately determines the eye point position of the HUD system inside the vehicle through the coordinated work of the calibration part 1 and the leveling part 2. The calibration part 1 is arranged at a first set height relative to the vehicle floor in the vehicle and is equipped with a positioning mark, while the leveling part 2 is arranged at a second set height and is used to emit light for the positioning component 11 to align the optical path. This design allows the eye point position to be accurately located in three dimensions (length, width and height), thereby improving the accuracy and reliability of the HUD system.

[0064] The design of the device allows for quick setup and adjustment inside the vehicle without the need for complex measuring tools or disassembly of vehicle components. By using positioning markers and light alignment, the reliance on specialized equipment is reduced, the efficiency of eyepoint position determination is improved, the debugging time is shortened, and the cost is also reduced.

[0065] In addition, the device is designed to be adaptable to different vehicle models. By setting different heights and using positioning markers, the device can be adapted to a variety of vehicle configurations. The threshold range, shape and style of the positioning markers can also be customized according to user needs, increasing the flexibility of the device.

[0066] The stability of the device is enhanced by the symmetrically arranged fixing part 4 and the calibration part 1, and the leveling part 2 located between the two calibration parts 1. The design of the fixing part 4, such as the clamping mechanism, makes the device easy to install in the vehicle, such as clamping on the sun visor of the vehicle.

[0067] The leveling part 2 includes a light emitting structure 22 and a leveling structure 21, which ensures that the emitted light is parallel to the vehicle floor, and helps to accurately determine the position of the eye point in the height and length directions. The reinforcing structure 5 on the mounting plate 3 is used to increase the strength of the mounting plate 3, while reducing the thickness and mass of the mounting plate 3, thereby reducing the difficulty of installation.

[0068] Further, see Fig.13 The present disclosure also provides an eye point position determination system, comprising a calibration unit 1, a positioning component 11 and a leveling unit 2, wherein the calibration unit 1 is arranged at a first set height relative to the vehicle floor in the vehicle; the positioning component 11 is used to determine the position of the eye point in the width direction of the vehicle according to the positioning mark on the calibration unit 1; the leveling unit 2 is arranged at a second set height relative to the vehicle floor in the vehicle, and is used to emit light for the positioning component 11 to perform optical path alignment to determine the position of the eye point in the height direction of the vehicle; wherein the first set height and the second set height are equal within a threshold range.

[0069] It should be noted that the specific details of the calibration unit 1, the positioning assembly 11 and the leveling unit 2 can be referred to the description of the eye point position determination device, which will not be elaborated here.

[0070] When determining the above-mentioned eye point position, the above-mentioned leveling part 2 can first determine the position of the above-mentioned positioning component 11 in the Z-axis direction and the X-axis direction, that is, the position in the length direction and the height direction, and then the positioning component 11 determines the position of the positioning component 11 in the vehicle width direction according to the positioning mark. After the position determination of the positioning component 11 is completed, the position of the positioning component 11 can be determined as the eye point position.
