Abstract

A vehicle auxiliary display device includes: a first camera configured to acquire a first image of a position of a user; a second camera configured to acquire a second image within a first range on an outside of a pillar of a vehicle; and a processor configured to determine a shielding area of the pillar shielding the user's line of sight based on the first image, extract an image of the shielding area from the second image based on the second image, and send the image of the shielding area to the user.

First claim

What is claimed is:

1. A vehicle auxiliary display device, comprising:
a first camera configured to acquire a first image of a position of a user;
a second camera configured to acquire a second image within a first range on an outside of a pillar of a vehicle;
a processor configured to determine a shielding area of the pillar shielding the user's line of sight based on the first image, extract an image of the shielding area from the second image based on the second image, and send the image of the shielding area to the user; and
a display configured to display the image of the shielding area,
wherein the second camera forms a first angle with respect to the direction perpendicular to the plane provided with the vehicle and is configured to acquire the second image,
the display forms a second angle with respect to the direction perpendicular to the plane provided with the vehicle,
the display is disposed on an A pillar of the pillar, so that the image of the shielding area displayed on the display can be inclined relative to an edge of the display but not inclined relative to the direction perpendicular to the plane provided with the vehicle, and
the first angle, the second angle and an angle of the A pillar relative to the direction perpendicular to the plane provided with the vehicle are all equal,
the first camera is configured to acquire the first image according to a first space determined by an area provided with a main driving seat and a height of an A pillar as the pillar in a direction perpendicular to a plane provided with the vehicle, and
the second camera is configured to acquire the second image according to a second space defined by first extension lines of connecting lines of at least part of vertexes of the first space and at least part of vertexes of the A pillar.

2. The device according to claim 1 , wherein the first image acquired by the first camera includes an image of the user's eyes; and
the processor determines a position of the user's eyes based on the first image, determines a coordinate of the user's eyes in the first space based on the position of the user's eye, and determines the shielding area of the A pillar shielding the user's line of sight based on the coordinate.

3. The device according to claim 2 , wherein
the processor determines second extension lines of connecting lines from the coordinate to the vertexes of the A pillar, and determines the shielding area of the A pillar shielding the user's line of sight based on the second extension lines.

4. The device according to claim 3 , wherein the processor determines vertexes of the shielding area in the second image according to the second extension lines, and extracts the image of the shielding area from the second image based on the vertexes of the shielding area.

5. A vehicle, comprising: pillars and the vehicle auxiliary display device according to claim 1 ,
wherein one of the pillars is equipped with a display of the vehicle auxiliary display device.

6. The vehicle according to claim 5 , wherein the pillars include A pillars; and the vehicle auxiliary display device is disposed on at least one A pillar on the front of the vehicle.

7. The vehicle according to claim 6 , wherein the at least one A pillar includes a body; the body includes a barrier part and a safety airbag; and the barrier part is configured to isolate the safety airbag from the display.

8. The vehicle according to claim 7 , wherein the at least one A pillar further includes a shield; and the shield is capable of covering the body of the A pillar and is able to be turned on or off relative to the body of the A pillar.

9. The vehicle according to claim 8 , wherein an opening is disposed at a position of the shield corresponding to the display and configured to expose a display area of the display.

10. The device according to claim 1 , wherein the display is a rectangular display.

11. A display method of a vehicle auxiliary display device, the vehicle auxiliary display device comprising a first camera and a second camera, the display method comprising:
adopting the first camera to acquire a first image of a position of a user;
adopting the second camera to acquire a second image within a first range on an outside of a pillar;
determining a shielding area of the pillar shielding the user's line of sight based on the first image, and extracting an image of the shielding area from the second image based on the second image;
sending the extracted image of the shielding area to the user; and
displaying the image of the shielding area on a display,
wherein the second camera forms a first angle with respect to the direction perpendicular to the plane provided with the vehicle and is configured to acquire the second image,
the display forms a second angle with respect to the direction perpendicular to the plane provided with the vehicle,
the display is disposed on an A pillar of the pillar, so that the image of the shielding area displayed on the display can be inclined relative to an edge of the display but not inclined relative to the direction perpendicular to the plane provided with the vehicle, and
the first angle, the second angle and an angle of the A pillar relative to the direction perpendicular to the plane provided with the vehicle are all equal,
the first camera is adopted to acquire the first image according to a first space determined by an area provided with a main driving seat and a height of an A pillar as the pillar in a direction perpendicular to the plane provided with the vehicle, and
the second camera is adopted to acquire the second image according to a second space formed by first extension lines of connecting lines of at least part of vertexes of the first space and at least part of vertexes of the A pillar.

12. The display method according to claim 11 , wherein the first camera is adopted to acquire the first image including an image of the user's eyes,
determine the position of the user's eyes based on the first image, determine a coordinate of the position of the user's eyes in the first space based on the position of the user's eye, and determine the shielding area of the A pillar shielding the user's line of sight based on the coordinate.

13. The device according to claim 11 , wherein the display is a rectangular display.
