Abstract

The invention discloses a low-illumination enhancement processing method and device and a computer readable storage medium. The method comprises the steps of obtaining source image data subjected to low-illumination enhancement processing in real time; Obtaining a local area description value corresponding to each pixel from the source image data; Taking each pixel and the corresponding local areadescription value as an entry address of a built-in color value lookup table, and looking up a color value used during pixel display in real time; And updating corresponding pixels in the source image data in real time by using the color values, and changing the source image data in real time to obtain enhanced image data. A color value mapped by each pixel and a local area description value corresponding to the pixel is obtained; While the controllability is ensured, the source image data is more carefully processed, so that the image enhancement effect is improved, however, due to the factthat the algorithm is simple and the color value lookup table is built in the algorithm, the real-time performance can be improved, the support of high hardware configuration is not needed, and the method can be applied to common hardware equipment.

Description

[0001] technology neighborhood [0002] The invention relates to the field of computer vision application technology, in particular to a low-illuminance enhancement processing method, device and computer-readable storage medium. Background technique [0003] Video technology and computer vision technology have a wide range of applications in various neighborhoods, such as traffic safety monitoring, automatic assisted driving, remote video chat and video entertainment. Various image data are obtained in these applications, and the obtained image data will finally realize the output display of corresponding images. [0004] Images contain the most complete and abundant information, and people often rely on images to obtain more complete and abundant information. Usually, the image quality will be affected by the ambient light. In the case of sufficient light during the day, the image quality of the output display can still meet the application requirements, but at night or in o...
