Abstract

The invention discloses a signal lamp image processing method, device and equipment and a storage medium, and belongs to the technical field of image processing. The method comprises the following steps: acquiring a long exposure image and a short exposure image obtained by shooting a signal lamp; carrying out halo suppression processing on the long exposure image, carrying out format conversion,and obtaining a first image, wherein the first image is a red, green and blue RGB image; carrying out format conversion on the short exposure image, carrying out color adjustment processing, and obtaining a second image, wherein the second image is an RGB image; and carrying out fusion processing on the first image and the second image, and carrying out format conversion to obtain a signal lamp image after correction processing. By fusing the first image and the second image, the corrected signal lamp image is obtained, the contour and color of the signal lamp can be accurately recovered, thesignal lamp of any color is corrected, the correction effect of the signal lamp image is improved, the universality is improved, the calculated amount is small, and the processing efficiency is high.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a signal light image processing method, device, equipment and storage medium. Background technique [0002] With the rapid development of image processing technology, the application scope of video surveillance is becoming wider and wider, and it is often used in urban traffic monitoring, such as traffic monitoring, vehicle violation records, road traffic analysis, etc. When carrying out video surveillance on urban traffic, it is necessary to comprehensively consider the signal light display and vehicle traffic conditions of the traffic section. Therefore, shooting equipment is usually used to shoot key traffic sections to obtain images including vehicle areas and signal light areas. Vehicles passing under certain display conditions. [0003] However, when the light is dark under certain environmental conditions, in order to capture a clear vehicle, it is often ...
