Problems solved by technology

[0003] At present, in order to prevent large distortions in the captured road conditions images, a camera with a smaller field of view is usually selected as the reversing camera, resulting in a large blind spot in the actual use of the reversing image, that is, the field of view shown to the driver is relatively limited

Embodiment Construction

[0062] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention, but not to limit the present invention.

[0063] In order to show the driver a wider field of vision and minimize the blind spot for reversing, a camera with a large field of view can be used as a reversing camera. However, due to the large depth of field of the image, the captured image may be seriously distorted, which brings great inconvenience to the driver and reduces the user experience. Based on this, the present invention provides a reversing image display solution, which can not only increase the visual field of the reversing image display, but also effectively solve the image distortion of road conditions.

[0064] The solution of the present invention will be explained below with reference to specifi...

Abstract

The invention discloses a reversing video display method and a device. The method comprises the following steps: acquiring an original road image taken by a wide-angle reversing camera; acquiring a pixel location mapping table, wherein the mapping table stores the corresponding relationship between the coordinates of the pixels in a display road image and the coordinates of the pixels in the original road image; and mapping the pixels of the original road image according to the corresponding relationship to get the display road image, and showing the display road image through vehicle multimedia. Thus, the field range of reversing video display is increased, and road image distortion is well solved.

Description

technical field [0001] The present invention relates to the field of image processing, in particular to a method and device for displaying a reversing image. Background technique [0002] The reversing image is a visual aid system that assists the driver in reversing. When reversing, the reversing camera at the rear of the vehicle can capture images of the road conditions behind the vehicle, and transmit the captured images of road conditions to the center console, and display them to the driver through the on-board multimedia. In this way, the driver can sit in the cab and observe the road conditions behind the vehicle, which is convenient for reversing. [0003] At present, in order to prevent large distortions in the captured road conditions images, a camera with a smaller field of view is usually selected as the reversing camera, resulting in a large blind spot in the actual use of the reversing image, that is, the field of view shown to the driver is relatively limited...
