[0028] The serial numbers assigned to the components in this article, such as "first", "second", etc., are only used to distinguish the described objects and do not have any sequential or technical meanings. And the "connection" and "coupling" mentioned in this application, unless otherwise specified, both include direct and indirect connections (couplings).
[0029] Please refer to Figures 1-3, In one embodiment, a vehicle body environment display system includes an acquisition component 8, a head-mounted display device 10, and a data transmission module 9. The acquisition component 8 includes a speed measurement unit and multiple cameras. The cameras are used to be arranged on the vehicle body 7 to acquire environmental images around the vehicle body 7, and the speed measurement unit is used to be arranged on the vehicle body 7 to detect the real-time speed of the vehicle body 7 moving.
[0030] The cameras can be installed in the blind spots of the vehicle's line of sight. For example, due to the occlusion of the engine hood, there is a certain blind spot in the front directly ahead of the vehicle. The cameras can be arranged at the middle position of the air intake grille of the vehicle body 7, or at the vehicle logo of the vehicle body 7, etc., and then the field of view of the cameras is adjusted to include the blind spot in the front directly ahead.
[0031] The speed measurement unit can be a wheel speed sensor configured at the wheel position. The wheel speed sensor can detect the rotational speed of the wheel and convert the rotational speed value into an electrical signal. The data transmission module 9 is used to connect the acquisition component 8 and the head-mounted display device 10. The electrical signal reaches the head-mounted display device 10 through the data transmission module 9, and the real-time vehicle speed is displayed through the display unit.
[0032] The head-mounted display device 10 includes a display unit and a sensor. The sensor is used to detect the direction that the head-mounted display device 10 is facing. The display unit is used to display the real-time speed and the environmental images acquired by the cameras arranged in the above-mentioned direction. The head-mounted display device 10 can be an AR (Augmented Reality) glasses. The driver can not only see the real road conditions in the field of view of the AR glasses, but also see the environmental images around the vehicle body 7 superimposed on the AR glasses.
[0033] In the AR glasses, the sensor can be a gyroscope. The gyroscope can know the direction that the AR glasses are facing by measuring the angular velocity and direction. The data transmission module 9 transmits the environmental images acquired by the cameras to the head-mounted display device 10, and then the display unit displays the environmental images acquired by the cameras arranged in this direction for the driver to view.
[0034] Through the above vehicle body environment display system, the driver can intuitively see the environmental images in the blind spots of the vehicle's line of sight through the display unit, achieving the effect of a "transparent vehicle body", and this process does not require the driver to lower their head, avoiding the safety risks brought by the line of sight leaving the road surface completely. In addition, when the "transparent vehicle body" mode is not used, the AR glasses can also be connected to the navigation system to display the navigation information and vehicle speed information in real time.
[0035] For the convenience of describing the position of the cameras, "front, rear, left, right" in the following text are all referenced with the driver's seat as the reference.
[0036] In some embodiments, please refer to Figures 1-3, the acquisition component 8 includes a first camera 1. The first camera 1 is used to be arranged on the front side of the vehicle body 7 to acquire the environmental image of the front blind area of the vehicle body 7. Specifically, the first camera 1 can be arranged at the middle position of the intake grille of the vehicle, or at the vehicle logo, etc., and then the field of view of the first camera 1 is adjusted to include the line of sight blind area in the front. When the driver wears the head-mounted display device 10 and faces directly forward, the driver can see the environmental image acquired by the first camera 1 through the display unit.
[0037] In some embodiments, please refer to Figures 1-3 , the acquisition component 8 includes a second camera 2 and a third camera 3. The second camera 2 is used to be arranged on the left front side of the vehicle body 7 to acquire the environmental image of the left front blind area of the vehicle body 7, and the third camera 3 is used to be arranged on the right front side of the vehicle body 7 to acquire the environmental image of the right front blind area of the vehicle body 7.
[0038] For example, the second camera 2 can be arranged below the left rearview mirror on the vehicle body 7, and the third camera 3 can be arranged below the right rearview mirror on the vehicle body 7. Adjust the second camera 2 and the third camera 3 so that their field of view ranges cover the left A-pillar blind area and the right A-pillar blind area of the vehicle. When the driver wears the head-mounted display device 10 and the head deflects by a certain angle, the gyroscope detects the change in the forward direction of the head-mounted display device 10, and then the display unit displays the environmental image acquired by the camera in that direction.
[0039] In some embodiments, please refer to Figures 1-3 , the acquisition component 8 includes a fourth camera 4. The fourth camera 4 is used to be arranged on the rear side of the vehicle body 7 to acquire the environmental image of the rear blind area of the vehicle body 7. Specifically, the fourth camera 4 can be arranged on the trunk lid of the vehicle body 7, and the field of view of the fourth camera 4 is adjusted to include the blind area at the rear of the vehicle body 7.
[0040] In some embodiments, the acquisition component 8 includes a fifth camera 5 and a sixth camera 6. The fifth camera 5 is used to be arranged on the left rear side of the vehicle body 7 to acquire the environmental image of the left rear blind area of the vehicle body 7, and the sixth camera 6 is used to be arranged on the right rear side of the vehicle body 7 to acquire the environmental image of the right rear blind area of the vehicle body 7. For example, the fifth camera 5 can be arranged at the upper part of the left rear wheel of the vehicle body 7, and the sixth camera 6 can be arranged at the upper part of the right rear wheel of the vehicle body 7. Adjust the fifth camera 5 and the sixth camera 6 respectively so that their field of view ranges cover the left C-pillar blind area and the right C-pillar blind area of the vehicle body 7.
[0041] In some embodiments, the head-mounted display device 10 is an AR glasses, and the display unit includes a lens and a projection device. The projection device is configured to project an environmental image and real-time speed onto the lens. The lens can be made of a transparent material, allowing the driver to observe the real road conditions through the lens. Meanwhile, the lens can clearly present the image generated by the projection device in the user's field of view.
[0042] The projection device is disposed in the internal structure of the AR glasses and can project the environmental image and real-time speed information onto the lens, so that the user can see the environmental image and real-time speed around the vehicle body 7 superimposed thereon while observing the real world. The optical path between the projection device and the lens may include other optical elements, such as mirrors, lenses or waveguides, etc., to optimize the clarity and brightness of the image and ensure that the user can clearly see the projection information without disturbing their observation of the real environment.
[0043] In some embodiments, the sensor is a gyroscope, and the gyroscope is used to detect the steering angle of the AR glasses to determine the facing direction of the AR glasses. The AR glasses may be provided with a processor, and the gyroscope is connected to the processor of the AR glasses. The processor calculates the attitude information of the glasses, such as the pitch angle, roll angle and heading angle of the glasses, that is, the rotation angles of the glasses in three-dimensional space, according to the electrical signal output by the gyroscope. Through the above attitude information, the facing direction of the glasses can be determined in real time, so that the display unit of the AR glasses can dynamically adjust the displayed content according to the head movement of the user.
[0044] In some embodiments, the data transmission module 9 includes a transmitter and a receiver. The transmitter is configured to collect and transmit the environmental image of the camera, and the receiver is configured to receive the environmental image. The transmitter is disposed on the vehicle body 7, and the receiver is disposed on the AR glasses. Specifically, the transmitter can collect the environmental image of the camera, then encode it into a format suitable for wireless transmission and transmit it. The receiver receives the image data transmitted from the transmitter and decodes it into a format that can be processed by the display unit of the AR glasses.
