Problems solved by technology

[0003] When using traditional mirror rearview mirrors, drivers need to adjust the angle of mirror rearview mirrors to control the reflection content to suit their own conditions due to different heights, front and rear positions, or different line of sight angles of drivers. However, electronic rearview mirrors The display content of the mirror cannot be adjusted due to the fixed shooting angle of the rear camera, which brings inconvenience to the driver
[0004] In addition, the FOV of the rear camera is generally larger than the FOV of the display screen in the electronic rearview mirror. When using it, the excess rearview image is often cut off, wasting the content of this part of the rearview image.

Embodiment 1

[0034] Such as Figure 1-3 As shown, a vehicle rear view system includes a rear camera 1, an electronic rear view mirror 2, an angle sensor 4 and a controller 3, and the controller 3 is electrically connected to the rear camera 1, the electronic rear view mirror respectively 2 and an angle sensor 4; the controller 3 is used to intercept a partial image B in the rear view image A obtained by the rear camera 1, and then display the partial image B on the electronic rearview mirror 2 , and according to the rotation angle of the electronic rearview mirror 2 acquired by the angle sensor 4, the interception position of the partial image B in the rearview image A is controlled to move accordingly.

[0035] The number of the rear camera 1 is at least one, preferably arranged directly behind the vehicle, such as the rear bumper, the rear door or the rear windshield, depending on the specific circumstances, it can also be arranged on the rear door or the roof On the other hand, as long...

Embodiment 2

[0059] A vehicle rear view method, not limited to the vehicle rear view system described in Embodiment 1, comprising:

[0060] Use the rear camera 1 to obtain the rear view image A of the rear of the vehicle;

[0061] Intercepting a partial image B from the acquired rear view image A;

[0062] Using the electronic rearview mirror 2 to display the intercepted partial image B;

[0063] Adopt angle sensor 4 to obtain the rotation angle of electronic rearview mirror 2;

[0064] According to the obtained rotation angle, the interception position of the partial image B in the back view image A is controlled to move accordingly.

[0065] Wherein, the angle sensor 4 can acquire the rotation angle of the electronic rearview mirror 2 in at least one direction, which corresponds to the movement of the interception position of the partial image B in the rearview image A in at least one direction.

[0066] The vehicle rear view method also includes:

[0067] Use a button element or a k...

Abstract

The invention discloses a vehicle rear viewing system and method. The vehicle rear viewing system comprises a back camera, an electronic rearview mirror, an angle sensor and a controller, and the controller is separately connected with the back camera, the electronic rearview mirror and the angle sensor electrically; the controller is used for capturing a local image of a rear view image obtainedby the back camera, then the local image is displayed on the electronic rearview mirror, and the capturing position of the local image in the rear view image is controlled to be moved correspondinglyaccording to the rotating angle, obtained by the angle sensor, of the electronic rearview mirror. The vehicle rear viewing system can adjust the rotating angle of the electronic rearview mirror to control displayed content.

Description

technical field [0001] The invention relates to rearview mirror technology, in particular to a vehicle rearview system and method. Background technique [0002] With the development of electronic technology, more and more vehicles begin to use electronic rearview mirrors to provide drivers with rearview images. Electronic rearview mirrors need to install a rear camera at the rear of the vehicle to capture images for display purposes. For the rear view image, the shooting angle of the rear camera is generally fixed. [0003] When using traditional mirror rearview mirrors, drivers need to adjust the angle of mirror rearview mirrors to control the reflection content to suit their own conditions due to different heights, front and rear positions, or different line of sight angles of drivers. However, electronic rearview mirrors The display content of the mirror cannot be adjusted due to the fixed shooting angle of the rear camera, which brings inconvenience to the driver. [0...
