Description

Technical Field

[0001] This invention relates to the technical field of head-up display devices for vehicles, and in particular to a detection device for a head-up display device in a vehicle, a detection method for a head-up display device in a vehicle, a detection apparatus for a head-up display device in a vehicle, and a computer-readable storage medium. Background Technology

[0002] HUD (Head-Up Display) uses projection technology to display information (such as vehicle speed, navigation, warnings, etc.) on a transparent screen or windshield, ensuring that drivers can obtain information without looking down.

[0003] When testing HUDs during the production verification phase, the relevant technology can use the seat mounting point as a fixed position for the HUD testing equipment; however, this method requires removing the driver's seat, which will disrupt the installation status of vehicles that have already rolled off the production line and increase the installation recovery time.

[0004] In addition, such as Figure 1 As shown, related technologies can also utilize the steering wheel as a fixed position for the HUD testing device (the HUD testing device includes a fixing plate 1, a C-shaped fixing clamp 2, a gear dial 3, a connecting rod 4, and an image acquisition unit 5; the C-shaped fixing clamp 2 is used to connect the HUD testing device to the steering wheel 6; the fixing plate 1 can be connected to the C-shaped fixing clamp 2 and the gear dial 3, the gear dial 3 can be connected to the image acquisition unit 5 through the connecting rod 4, the gear dial 3 can be used to adjust the position of the image acquisition unit 5, and the image acquisition unit 5 can be used to acquire the image displayed in the HUD); however, this method only uses the shape of the steering wheel for positioning, and due to the rotational nature of the steering wheel, the positioning accuracy is low. At the same time, the testing device needs to consider center of gravity balancing, and this solution is only suitable for steering wheels with non-adjustable height. For steering wheels with adjustable height and depth, additional positioning and calibration equipment is required to meet the HUD testing requirements, resulting in higher costs.

Detailed Implementation

[0037] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0038] To test HUDs during production verification without disrupting the installation state of vehicles already off-line, and to reduce testing costs and improve positioning accuracy, this invention provides a testing device for HUDs in vehicles. This testing device uses the vehicle door as a fixed position, employing a door frame fixing module to secure the testing device to the door before testing. This eliminates the need to disrupt the installation state of the off-line vehicle. Furthermore, since the door's position is fixed, installing the testing device based on the door eliminates the need for additional positioning equipment, further reducing testing costs. The fixed door position also provides a stable base for the testing device, improving its positioning accuracy.

[0039] For specific details, please refer to Figure 2 The diagram shows a structural schematic of a detection device for a head-up display device in a vehicle according to an embodiment of the present invention.

[0040] like Figure 2 As shown, the detection equipment for the head-up display device in the vehicle may include: a door frame fixing module 8, a data acquisition module 9, and a control module 10; wherein:

[0041] The acquisition module 9 is connected to the door frame fixing module 8; the control module 10 is electrically connected to the acquisition module 9, and the door frame fixing module is used to connect the detection equipment to the door.

[0042] In this embodiment of the invention, the detection device may include a door frame fixing module 8, a data acquisition module 9, and a control module 10; wherein, the door frame fixing module 8 can be used to fix the detection device to the door 7; for example, since different doors 7 have different sizes and shapes, different door frame fixing modules 8 can be customized for different doors 7; when detecting the HUD of vehicles corresponding to different doors, different door frame fixing modules 8 and data acquisition modules 9 can be used to connect and use.

[0043] In some feasible embodiments, the door frame fixing module 8 can be a snap-on structure to connect with the door; the door frame fixing module 8 can also be a pin-type structure, or a magnetic fixing structure, a friction fixing structure, an elastic clamp, etc., and the embodiments of the present invention do not limit this.

[0044] The acquisition module 9 can be used to acquire the image displayed by the head-up display device and output the acquired image to the control module 10 to detect the imaging quality of the head-up display device.

[0045] For example, the door frame fixing module 8 can be connected to the acquisition module 9. The acquisition module 9 can be placed in the vehicle cabin and connected to the door frame fixing module 8. The door frame fixing module 8 can fix the acquisition module 9 to the vehicle door 7, thereby providing a stable base for the acquisition module 9.

[0046] The control module 10 may be equipped with camera positioning and control software to control the acquisition module 9 and detect the HUD.

[0047] In practical applications, the control module 10 can be electrically connected to the acquisition module 9 to move the acquisition area of ​​the acquisition module 9. Additionally, the control module 10 can receive the image output by the acquisition module 9 based on the image displayed on the head-up display (HUD), and then use this image to detect the imaging quality of the HUD. Through this embodiment of the invention, during the production verification stage, the HUD can be directly fixed to the door 7 via the door frame fixing module 8, eliminating the need to remove the vehicle seat and thus avoiding damage to the installation state of the off-line vehicle. Furthermore, compared to using the steering wheel as a fixed position, no additional positioning and calibration equipment is required, reducing testing costs. Moreover, compared to using the steering wheel as a fixed position, the position of the door 7 is fixed when closed, improving the positioning accuracy of the testing equipment.

[0048] In one embodiment of the present invention, such as Figure 3 As shown, the acquisition module 9 includes: an acquisition unit 11 and a support unit 12, wherein:

[0049] The bracket unit 12 is fixedly connected to the vehicle door 7 via the door frame fixing module 8; the acquisition unit 11 is mounted on the bracket unit 12; and the control module 10 is connected to the acquisition unit 11.

[0050] In some feasible embodiments, the acquisition module 9 may consist of an acquisition unit 11 and a support unit 12; wherein, the acquisition unit 11 may be used to acquire the image displayed by the head-up display device and transmit the image output after acquiring the image displayed by the head-up display device to the control module 10; the control module 10 may detect the imaging quality of the head-up display device based on the image.

[0051] The bracket unit 12 can serve as a base to support the acquisition unit 11. Specifically, the bracket unit 12 can be connected to the door frame fixing module 8 so as to be fixedly connected to the vehicle door 7 through the door frame fixing module 8.

[0052] The acquisition unit 11 can be mounted on the support unit 12; the control module 10 can be used to move the acquisition area of ​​the acquisition unit 11. For example, the control module 10 can control the acquisition unit 11 to move on the support unit 12 in order to control the movement of the acquisition area of ​​the acquisition unit 11. Of course, if the acquisition unit 11 can be internally adjusted, the control module 10 can also directly control the internal structure adjustment of the acquisition unit 11 to control the movement of the acquisition area of ​​the acquisition unit 11. This embodiment of the invention does not limit this.

[0053] In one embodiment of the present invention, such as Figure 3 As shown, the door frame fixing module 8 includes a first door frame fixing unit 13 and a second door frame fixing unit 14; the bracket unit includes a first bracket sub-unit 22 extending along the Y direction, the first door frame fixing unit 13 is connected to one end of the first bracket sub-unit 22 in the Y direction, and the second door frame fixing unit 14 is connected to the other end of the first bracket sub-unit 22 in the Y direction, the Y direction being parallel to the line connecting the same row of doors 7 of the vehicle.

[0054] In some feasible embodiments, the door frame fixing module 8 may include a first door frame fixing unit 13 fixedly connected to one side door 7 of the vehicle, and a second door frame fixing unit 14 fixedly connected to the other side door 7 of the vehicle; the bracket unit may include a first bracket sub-unit 22 extending along the Y direction, wherein the Y direction may be parallel to the line connecting the doors 7 of the same row of the vehicle; for example, the Y direction may be parallel to the line connecting the front left door and the front right door, and the embodiments of the present invention do not limit this.

[0055] One end of the first bracket subunit 22 in the Y direction can be connected to the first door frame fixing unit 13, and the other end of the first bracket subunit 22 in the Y direction can be connected to the second door frame fixing unit 14.

[0056] Taking a four-door vehicle as an example, the vehicle includes a left front door, a right front door, a left rear door, and a right rear door; then the first door frame fixing unit 13 can be fixedly connected to the left front door, the second door frame fixing unit 14 can be fixedly connected to the right front door, and the first door frame fixing unit 13 can be connected to one side of the first bracket sub-unit 22, and the second door frame fixing unit 14 can be connected to the other side of the first bracket sub-unit 22, so that the first bracket sub-unit 22 can be fixedly connected to the left front door and the right front door respectively through the first door frame fixing unit 13 and the second door frame fixing unit 14.

[0057] The first bracket subunit 22, which is fixedly connected to the left front door and the right front door, can serve as a stable base for the acquisition unit 11. Since the position of the door 7 is fixed, by designing the dimensions of the first bracket subunit 22, the first door frame fixing unit 13 and the second door frame fixing unit 14, and the fixed positions of the first door frame fixing unit 13 and the second door frame fixing unit 14 with the door 7, the positioning accuracy of the acquisition unit 11 can be guaranteed without the need for additional equipment for positioning and calibration.

[0058] In one embodiment of the present invention, the acquisition unit 11 includes a camera subunit and a motion subunit; the camera subunit and the motion subunit are drivenly connected, and the motion subunit is disposed on the support unit 12; wherein:

[0059] The control module 10 is used to control the motion subunit so that the camera subunit moves.

[0060] In some feasible embodiments, the acquisition unit 11 may include a camera subunit for acquiring the image displayed on the head-up display device, and a motion subunit for moving the camera subunit; wherein the camera subunit may be movably connected to the motion subunit, and the motion subunit may be mounted on the support unit 12; the control module 10 may control the movement of the camera subunit by controlling the motion subunit; and control the movement of the acquisition area of ​​the camera subunit by controlling the movement of the camera subunit.

[0061] For example, the motion subunit can control the movement of the camera subunit via a lead screw or a conveyor belt, and this embodiment of the invention does not impose any limitations on this. The motion subunit allows the camera subunit to acquire images from different positions, thereby improving the coverage of HUD image quality detection and enhancing the analytical capabilities of the detection.

[0062] In one embodiment of the present invention, the motion subunit includes a first direction motion subunit and a second direction motion subunit; the camera subunit is connected to the first direction motion subunit, and the first direction motion subunit is movably connected to the second direction motion subunit;

[0063] The control module 10 is used to control the first direction motion subunit to drive the camera subunit to move along the first direction; and to control the second direction motion subunit to drive the camera subunit to move along the second direction.

[0064] In some feasible embodiments, the motion subunit may include a first-direction running subunit that moves the camera subunit in a first direction, and a second-direction running subunit that moves the camera subunit in a second direction; wherein, the first direction may be the Y direction, and the second direction may be the Z direction; for example, the Y direction may be the lateral direction of the vehicle, i.e., the direction of the line connecting one side door and the other side door; the Z direction may be the vertical direction, i.e., the direction from the bottom of the vehicle to the top of the vehicle; and the X direction may be the vertical direction of the vehicle, i.e., the direction of the line connecting the door and the front of the vehicle, such as... Figure 4 As shown. The camera subunit can remain fixed in the X direction.

[0065] In practical applications, the camera subunit can be connected to the first direction motion subunit, and the first direction motion subunit can be connected to the second direction motion subunit; wherein, the first direction motion subunit can be controlled by the control module 10 to make the camera subunit move along the first direction.

[0066] In addition, the second direction motion subunit can also be controlled by the control module 10 to make the first direction motion subunit move along the second direction, thereby making the camera subunit move along the second direction.

[0067] In one embodiment of the present invention, such as Figure 5 As shown, the first direction motion subunit includes a first lead screw 17, a first optical axis 18, and a first motor 23; the second direction motion subunit includes a second lead screw 19, a base 20, and a second motor 24; the camera subunit is connected to the first lead screw 17 and the first optical axis 18; the first motor 23 is connected to the first lead screw 17, and the first optical axis 18 is parallel to the first direction.

[0068] The second motor 24 is connected to the second lead screw 19, the second lead screw 19 is connected to the base 20, and the base 20 is connected to the first lead screw 17 and the first optical axis 18; the second lead screw 19 is parallel to the second direction.

[0069] The control module 10 is used to control the operation of the first motor so that the first lead screw 17 drives the camera subunit to move along the first optical axis 18 in the first direction; and to control the operation of the second motor so that the second lead screw 19 drives the camera subunit to move in the second direction.

[0070] In some feasible embodiments, the first direction motion subunit may include a first motor 23 for providing power, a first lead screw 17 for moving the camera subunit, and a first optical axis 18 for providing guidance. The control module 10 controls the movement of the first motor 23, which rotates the first lead screw 17, thereby driving the camera subunit, which is movably connected to the first lead screw 17, to move in the first direction along the first optical axis 18, which serves as a guide. The camera subunit and the first lead screw 17 can be threaded together, and the camera subunit and the first optical axis 18 can be slidably connected; the first lead screw 17 and the first optical axis 18 can be arranged parallel to each other.

[0071] In some feasible embodiments, the first optical axis 18 can also restrict the rotation of the camera subunit to avoid the camera subunit from rotating due to the rotation of the first lead screw, which would affect the camera subunit's image acquisition.

[0072] Additionally, the second-direction motion subunit may include a base 20, a second motor 24 for providing power, and a second lead screw 19 for moving the camera subunit. The second lead screw 19 can be threadedly connected to the base 20 where the first motor 23 is located. When the control module 10 drives the second motor 24, it can rotate the second lead screw 19, thereby moving the base 20 threadedly connected to the second lead screw 19. Since the first motor 23 is actually connected to the camera subunit via the first lead screw 17, by setting the relative position of the first motor and the second lead screw 19, the first motor 23 can move the camera subunit along the second direction when it moves due to the rotation of the first lead screw 17.

[0073] In some feasible embodiments, such as Figure 5 As shown, the second lead screw 19 may include at least two, and the two second lead screws 19 may be parallel to each other to limit the rotation of the base 20, thereby preventing the camera subunit from rotating due to the rotation of the second lead screw 19.

[0074] Since the base 20 is threadedly connected to the second lead screw 19, and the base 20 is restricted from rotating by the second lead screw 19, the base 20 will move along the direction of the second lead screw 19, thereby driving the camera sub-unit to move.

[0075] For example, the line connecting the first lead screw 17 and the first motor 23 can be parallel to the first direction, and the line connecting the second lead screw 19 and the base 20 where the first motor 23 is located can be parallel to the second direction.

[0076] like Figure 5As shown, the camera subunit may include a camera 15 and a gimbal 16. The camera 15 can be connected to the first lead screw 17 and the first optical axis 18 via the gimbal 16. The gimbal 16 is fixedly connected to the camera 15. When the gimbal 16 moves under the drive of the first lead screw 17, it can move the camera 15.

[0077] The support unit 12 may also include a fixed support 21 parallel to the second direction to keep the second lead screw 19 always parallel to the second direction. For example, the fixed support 21 may be used to limit the position of the second lead screw 19 to serve as a guide.

[0078] For example, such as Figure 5 As shown, the first support subunit 22 of the support unit may include multiple subunits, and the first support subunits 22 can be connected to each other through the second support subunit 25 to improve the stability of the support unit.

[0079] In one embodiment of the present invention, the motion subunit includes a third-direction motion subunit and a fourth-direction motion subunit; the camera subunit is connected to the third-direction motion subunit and the camera subunit is connected to the fourth-direction motion subunit;

[0080] The control module 10 is used to control the third-direction motion subunit to drive the camera subunit to move along the first direction; and to control the fourth-direction motion subunit to drive the camera subunit to move along the second direction.

[0081] In some feasible embodiments, the motion subunit may include a third motion direction subunit movably connected to the camera subunit, and a fourth motion direction subunit movably connected to the camera subunit.

[0082] The third motion direction subunit can be controlled by the control module 10 to move the camera subunit along the first direction. The fourth motion direction subunit can be controlled by the control module 10 to move the camera subunit along the second direction.

[0083] For example, the third motion direction subunit may include a third moving rod and a third motor. The third moving rod is parallel to the first direction, the third motor is connected to the third moving rod, and the third moving rod is connected to the camera subunit. The third motor can drive the third moving rod to drive the camera subunit to move on the third moving rod.

[0084] The fourth motion direction subunit may include a fourth moving rod and a fourth motor. The fourth moving rod is parallel to the second direction, the fourth motor is connected to the fourth moving rod, and the fourth moving rod is connected to the camera subunit. The fourth motor can drive the fourth moving rod to drive the camera subunit to move on the fourth moving rod.

[0085] For example, the third moving rod can be a third lead screw, the fourth moving rod can be a fourth lead screw, and the third motor drives the camera subunit to move on the third lead screw by rotating the third lead screw.

[0086] When the third motor is running, the locking mechanism on the third motor can lock the third lead screw, so that the rotation of the third motor can drive the third lead screw; at this time, the locking mechanism on the fourth motor can not lock the fourth lead screw, so that the camera subunit is not restricted by the fourth lead screw when it moves in the direction corresponding to the third lead screw.

[0087] When the fourth motor is running, the locking mechanism on the fourth motor can lock the fourth lead screw, so that the rotation of the fourth motor can drive the fourth lead screw; at this time, the locking mechanism on the third motor can not lock the third lead screw, so that the camera subunit is not restricted by the third lead screw when it moves in the direction corresponding to the fourth lead screw.

[0088] In another example, the third motion direction subunit may include a third conveyor belt and a third motor. The conveying direction of the third conveyor belt is parallel to the first direction, and the camera subunit is connected to the third conveyor belt. The third motor can drive the third conveyor belt to drive the camera subunit to move in the first direction. The fourth motion direction subunit is similar to the third motion direction subunit and will not be described in detail here.

[0089] In one embodiment of the present invention, the detection device further includes:

[0090] The limit module is used to restrict the movement of the acquisition module 9 within the target area.

[0091] In some feasible embodiments, a limit module can be set to indicate the movement of the acquisition module 9 within the target area, so as to prevent the acquisition module 9 from moving out of the set area. For example, the limit module can be a limit switch. When the limit module moves to the position of the limit switch, the control module 10 can receive the signal output by the limit module, thereby determining the position of the acquisition module 9 and controlling the movement of the acquisition module 9.

[0092] Based on the above-described detection device, this embodiment of the invention also provides a method for detecting a head-up display device in a vehicle; specifically, refer to... Figure 6 The diagram illustrates a step flowchart of a method for detecting a head-up display device in a vehicle according to an embodiment of the present invention.

[0093] like Figure 6 As shown, the detection method for the head-up display device in the vehicle may include the following steps:

[0094] Step 601: Control the movement of the acquisition module of the detection equipment and control the acquisition module to acquire calibration images.

[0095] In this embodiment of the invention, the control module in the detection device can first control the acquisition module to move, and then control the acquisition module to acquire the image displayed by the head-up display device to obtain a calibration image.

[0096] Step 602: Detect the imaging quality of the head-up display device based on the calibration image.

[0097] Then, based on the calibration image, the offset of the calibration image relative to the center point of the preset grid in the first and second directions can be calculated, thereby detecting the imaging quality of the head-up display device.

[0098] For example, the detection equipment can be first assembled onto the vehicle door, and the initial position of the limit module can be recorded. The control module can control the camera subunit of the acquisition module, setting the orientation of the camera subunit to the standard viewing angle. The control module controls the motion subunit, moving the camera subunit to the origin of the eye-box coordinate system. The eye-box coordinate system represents the position of the driver's eyes in the overall vehicle design. The X-direction position is ensured by the initial door frame fixing module design.

[0099] Based on the calibration image acquired by the camera subunit, the control module can manipulate the motion subunit to move the position of the camera subunit so that the center point of the calibration image coincides with the center point of the preset built-in grid. The current position of the camera subunit is recorded as the origin position of the camera subunit, and the registration is completed.

[0100] Measurement data acquisition phase:

[0101] Step 1. Adjust the HUD setting (the setting of the display content height, which can be set to 0, 1, 2, etc.; where 0 means no height increase of the display content, and 1 means raising the display content by a preset unit height (e.g., 5cm, the unit height is not limited in this embodiment of the invention)) to 0. The control module controls the motion subunit to move at equal intervals along the first direction (as the Y direction) and the second direction (as the Z direction) from left to right and from top to bottom (or from right to left and from bottom to top), and captures calibration images of each position on the YZ plane corresponding to the setting.

[0102] Step 2. Calculate the offset of the Y and Z directions relative to the center point of the built-in grid based on the calibration image, and use it as a reference value for judging the imaging quality.

[0103] Repeat steps 1 and 2 to acquire calibration images corresponding to different gear positions, and comprehensively judge the HUD imaging quality.

[0104] In this embodiment of the invention, the acquisition module of the testing equipment is moved and a calibration image is acquired. Based on the calibration image, the imaging quality of the head-up display (HUD) is tested. Through this embodiment, during the production verification stage, the HUD can be directly fixed to the vehicle door using a door frame fixing module, eliminating the need to remove the vehicle seat and thus preserving the installation state of the off-line vehicle. Furthermore, compared to using the steering wheel as a fixed position, no additional positioning and calibration equipment is required, reducing testing costs. Additionally, the door's position is fixed when closed, improving the positioning accuracy of the testing equipment.
