Abstract

The present disclosure provides a vehicle display device, configured to be mounted on a sun visor frame, including: a controller for receiving surrounding images, labeling a reference object in the surrounding images, and determining a first image to be displayed from the surrounding images according to a comparison of the reference object and a real object corresponding to the reference object; a non-transparent display screen for displaying the first image in a driver'"'"'s sightline, wherein the non-transparent display screen is connected to the controller; and a plurality of image acquisition modules including a front camera, two side view cameras, and a rear view camera for capturing front images, left-side images, right-side images, and rear images of a vehicle.

Claims

1. A vehicle display device, configured to be mounted on a sun visor frame, comprising:

a controller for receiving surrounding images, labeling a reference object in the surrounding images, and determining a first image to be displayed from the surrounding images according to a comparison of the reference object and a real object corresponding to the reference object;

a non-transparent display screen for displaying the first image in a driver'"'"'s sightline, wherein the non-transparent display screen is connected to the controller;

an enhancement module connected to the controller, wherein the enhancement module is configured to adjust the surrounding images based on an enhancement algorithm to obtain adjusted surrounding images;

wherein the controller comprises;

an image selection unit configured to obtain a second image containing the reference object from the surrounding images;

an image comparison unit configured to compare the physical spaces between the reference object and a real object corresponding to the reference object;

an image determination unit configured to identify the second image as the first image to be displayed when the physical spaces between the reference object and the real object corresponding to the reference object are compatible; and

a photo-sensitive sensor connected to the controller, wherein the photo-sensitive sensor is configured to detect an ambient light intensity, and the controller adjusts a display brightness of the non-transparent display screen based on the ambient light intensity.

2. The vehicle display device according to claim 1, further comprising:

an image acquisition module connected to the controller, wherein the image acquisition module is configured to acquire the surrounding images of the vehicle.

3. The vehicle display device according to claim 2, further comprising:

a holder installed inside a vehicle cabin, wherein the non-transparent display screen is supported by the holder.

4. The vehicle display device according to claim 3, wherein the image acquisition module includes one or a plurality of cameras, and the camera or the plurality of cameras are installed outside the vehicle.

5. The vehicle display device according to claim 3, wherein the image acquisition module includes one or a plurality of cameras, and the camera or the plurality of cameras are installed on the holder.

6. The vehicle display device according to claim 3, wherein a shooting direction of one of the plurality of cameras is the same as a driving direction of the vehicle.

7. The vehicle display device according to claim 1, wherein the controller is connected to an electric control unit (ECU).

8. The vehicle display device according to claim 1, wherein the controller is connected to a vehicle entertainment unit.

9. The vehicle display device according to claim 1, further comprising:

a solar charging module connected to the controller.

10. The vehicle display device according to claim 1, wherein the non-transparent display screen is frameless.

17. A vehicle sun visor, comprising a sun visor frame, a vehicle display device according to claim 1, the non-transparent display screen of the vehicle display device being installed on the sun visor.

18. A vehicle, comprising one or more of the vehicle display devices according to claim 1.

19. A vehicle, comprising the vehicle sun visor according to claim 17.

11. An image display method for displaying an image of a surrounding environment of a vehicle, comprising:

acquiring surrounding images of a vehicle;

labeling a reference object in the surrounding images;

determining a first image to be displayed based on the surrounding images according to a comparison of the labeled reference object and a corresponding real object;

displaying the first image in real-time on a non-transparent display screen in a driver'"'"'s sightline;

adjusting the surrounding images based on an enhancement algorithm; and

obtaining adjusted surrounding images;

acquiring a second image containing the reference object from the surrounding images;

comparing physical spaces of the reference object in the second image and the corresponding real object in the second image;

defining the second image as the first image to be displayed when the physical spaces of the reference object and the real object corresponding to the reference object are compatible;

detecting an ambient light intensity; and

adjusting a display brightness of the non-transparent display screen according to the ambient light intensity.

12. The method according to claim 11, further comprising:

acquiring the surrounding images of the vehicle; and

labeling the reference object in the surrounding images based on a driving direction of the vehicle.

13. The method according to claim 12, further comprising:

acquiring the surrounding images of the vehicle via one or a plurality of cameras, wherein the camera or the plurality of cameras are installed inside the vehicle cabin, or the camera or the plurality of cameras are installed outside the vehicle body.

14. The method according to claim 13, further comprising:

displaying the first image and other surrounding images in real-time in the non-transparent display screen in a driver'"'"'s sightline.

15. The method according to claim 11, further comprising:

receiving and displaying a warning message on the non-transparent display screen together with the first image.

16. The method according to claim 11, further comprising:

acquiring and displaying a surrounding image reflecting a right-side view from the vehicle on the non-transparent display screen together with the first image;

a surrounding image reflecting a left-side view from the vehicle on the non-transparent display screen together with the first image; and

a surrounding image reflecting a rear view from the vehicle on the non-transparent display screen together with the first image.
