Problems solved by technology

In the process of reversing, the field of view displayed on the central control screen through the electronic rearview mirror is small, and there are many blind spots in the process of reversing, which is difficult to meet the needs of most drivers.
[0003] It can be seen that the technical problems existing in the prior art are: the current electronic rearview mirror still has the problems of small field of view and many blind spots during the reversing process

[0034] See figure 1 , shows a flow chart of an electronic rearview mirror image processing method provided by the first embodiment of the present invention, the method can be applied to the processor of the electronic rearview mirror, and can also be applied to other vehicle-mounted devices with processing capabilities middle. The method includes:

[0035] Step S10: When a reversing signal is detected, the original image frame of the original reversing image of the electronic rearview mirror camera is obtained.

[0036] In step S10, when the gear position of the vehicle is in the reverse gear, a reverse signal may be triggered. When a triggering reversing signal is detected, the original reversing image of the electronic rearview mirror can be acquired. Decoding the original reversing image can obtain the video frames constituting the reversing image, that is, the original image frame; further, for the convenience of processing, the format of the video frame can be transcod...

Abstract

The invention discloses an electronic rearview mirror image processing method and device; the method comprises the steps: obtaining an original image frame of an original reversing image of an electronic rearview mirror camera when a reversing signal is monitored; obtaining a first image and a second image based on the original image frame, wherein the first image is an image corresponding to the middle upper part of an original image frame, and the second image is an image corresponding to the middle lower part of the original image frame; reducing the second image according to a preset reduction scale to obtain a third image; and finally, splicing the first image and the third image to obtain a new image frame; and outputting the new image frame to a corresponding vehicle-mounted display, so that the vehicle-mounted display displays the newly added image range. According to the invention, the reversing safety is improved; meanwhile, during normal driving, normal display of the image range of the electronic rearview mirror is not affected.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to an image processing method and device for an electronic rearview mirror. Background technique [0002] With the development of science and technology, vehicles are becoming more and more intelligent and electronic. In order to assist driving, more and more family cars are equipped with reversing sensors, reversing images, 360-degree full-vehicle images, etc. Not only that, but the traditional rearview mirrors in family cars also tend to be gradually replaced by electronic rearview mirrors. However, there are still many defects to be solved in the current use of electronic rear view. For example, in the process of reversing the traditional electronic rearview mirror, if you want to see more range of vision, you can only achieve it by adjusting the line of sight of the human eye. In the process of reversing, the field of view displayed on the central control screen thro...
