Problems solved by technology

However, with the difference in light intensity, under the low-light environment of the traffic light, the color center of the traffic light will be overexposed, which will cause the red light to be yellowish and the green light to be white in the brightness center, which will lead to the feedback of illegal information. Problems with Unreliable Evidence Graphs

Abstract

The invention provides a color reduction method and device, and the method comprises the steps: collecting N video images in a monitoring frame; selecting the video image with a signal lamp being in a specific state from the N video images, wherein the specific state is a state that the color of the signal lamp meets the display requirements in a signal lamp switching process; and carrying out the signal lamp color reduction of a specific video image through the video image in the specified state. According to the technical scheme of the invention, the method can correct a specific video image (a video image with the overexposure phenomenon of the signal lamp), achieves the reasonable reduction of an overexposure region of the signal lamp, effectively solves an overexposure problem of the signal lamp, enables the color of the signal lamp to accord with the actual demands in a better way, solves a problem that the overexposure causes the color distortion of the signal lamp and the distortion of contour, inhibits the distortion of the signal lamp and the diffusion of halo, can improve the authenticity and reliability of an evidence violation map, and meets the demands of an evidence map of an intelligent traffic solution.

Description

technical field [0001] The present application relates to the technical field of video surveillance, in particular to a color restoration method and device. Background technique [0002] In recent years, with the rapid development of computers, networks, image processing, and transmission technologies, the trend of popularization of video surveillance systems has become more and more obvious. Video surveillance systems are gradually becoming high-definition and intelligent. Video surveillance systems can be applied to many Fields, such as intelligent transportation, smart parks, safe cities, etc. [0003] In the video surveillance system, the front-end equipment (such as network camera, analog camera, etc.) is an important part, and the video surveillance system includes a large number of front-end equipment, and these front-end equipment collect video images in various environments. If the front-end equipment collects video images in a low-light environment, the quality of...
