Abstract

The invention is suitable for the technical field of computer application, and provides an image enhancement method and device. The method comprises the following steps: obtaining a to-be-processed image photographed by a preset camera on a vehicle under a first illumination value; inputting the to-be-processed image into a pre-trained image enhancement model for processing to obtain a target image corresponding to a second illumination value; and displaying the target image on a preset display on the vehicle. An image enhancement model is obtained according to pre-training; carrying out imageenhancement on the to-be-processed image obtained in the low-illumination environment; according to the image enhancement method and device, the target image with high contrast and brightness is obtained and displayed on the display, so that a driver of the vehicle is assisted in checking the road surface state corresponding to the to-be-processed image, the image enhancement effect and accuracyare improved, and it is guaranteed that the driver can drive safely during night driving.

Description

technical field [0001] The present application belongs to the field of computer application technology, and in particular relates to an image enhancement method and device. Background technique [0002] In recent years, with the rapid development of deep learning methods, computer vision has been increasingly used in the design of advanced driver assistance systems and connected autonomous vehicles. These applications mainly focus on object detection and classification, semantic segmentation, instance segmentation, motion Estimation and monitoring system. However, most of the existing computer vision applications are camera-based and thus can only be used under normal light and clear weather conditions, which makes most state-of-the-art models unsuitable for nighttime images. [0003] In the prior art, the brightness is better distributed on the histogram through the image enhancement method, and the local contrast can be enhanced without affecting the overall contrast, or ...
