An image optimization enhancement method and system for a driving recorder

Abstract

The application relates to the field of image enhancement, in particular to an image optimization and enhancement method and system for a driving recorder, which comprises the following steps: acquiring multiple frames of road images collected during the working process of the driving recorder and an enhancement parameter vector thereof; constructing a historical enhancement benchmark of a current frame of road images; calculating the parameter deviation degree between the enhancement parameter vector of the current frame of road images and the historical enhancement benchmark and the image content change amount relative to the previous frame of road images, so as to judge whether the enhancement parameter of the current frame of road images is subjected to continuity constraint and determine the enhancement parameter vector finally used by the current frame of road images; and performing image enhancement on the current frame of road images by using the enhancement parameter vector finally used by the current frame of road images. The application aims to increase the consideration of the enhancement trajectory of the historical multiple frames of images and improve the continuity and stability of road image enhancement.
