Panoramic monitoring image device and working method thereof

Abstract

The present invention relates to a panoramic monitoring image device, comprising: a plurality of cameras, which are arranged on a vehicle; an image synthesis unit, which respectively receives a plurality of images from the plurality of cameras, and synthesizes the plurality of images to generate a panoramic monitoring image; A brightness correction unit, which receives the panoramic monitoring image, corrects and outputs the brightness of the panoramic monitoring image based on the brightness mean value and brightness variance of each area in the panoramic monitoring image; and an image display unit, which displays the brightness of the panoramic monitoring image. The corrected panoramic surveillance image. The present invention has the following effects: first, based on the brightness correction of the panoramic monitoring image, the problem of brightness inconsistency can be quickly dealt with. Second, in the case of shadows or obstacles in the panoramic surveillance image, the problem of brightness incongruity can be minimized. Third, there is no need to adjust the common shooting range when the installation and use of the camera is changed. Fourth, minimizing the brightness incongruity of the synthesized image can improve the perceptual quality.

Description

technical field [0001] The invention relates to a vehicle peripheral monitoring device and a method thereof for displaying a peripheral image of a vehicle, in particular to a panoramic monitoring image device and a method for correcting the brightness of a panoramic monitoring image. Background technique [0002] Currently, with the high-end and multi-functionalization of vehicles, vehicles are generally equipped with an Around View Monitoring (AVM) system. [0003] The Around View Monitor (AVM) system obtains images around the vehicle through cameras installed around the vehicle. When parking, the driver does not have to look hard at the rear or the surrounding area. The display device installed in the car can Check the systems around the vehicle. In addition, the panoramic monitoring video system also provides a panoramic (Around View) video as viewed from above the vehicle by synthesizing the above-mentioned peripheral video. Using this panoramic monitoring image system...

AI Technical Summary

Problems solved by technology

[0004] However, the existing panoramic monitoring image system synthesizes multiple images received from multiple cameras to display the panoramic monitoring image, so the difference in brightness of each image will cause a sense of incongruity.
