A signal light image processing method and device thereof

Abstract

The present invention provides a signal light image processing method and device thereof, the method comprising: S1, detecting the edge information of the signal light in a frame of image collected by a camera; S2, segmenting the signal light from the image according to the edge information of the signal light Exit the signal light area; S3, perform color enhancement on the signal light area in the image. The device includes: an edge detection module, configured to detect edge information of a signal light in a frame of image captured by a camera; an area segmentation module, configured to segment a signal light area from the image according to the edge information of the signal light; color The enhancement module is configured to enhance the color of the signal light area in the image. The invention can solve the distortion of the signal light color in the image collected when the ambient light intensity of the camera is too high or too low.

Description

technical field [0001] The invention relates to the technical field of video surveillance, in particular to a signal lamp image processing method and device thereof. Background technique [0002] In order to monitor violations at traffic intersections with signal lights, traffic management departments will install cameras at traffic intersections with signal lights. The camera usually adopts a fixed installation method, that is, the installation height, position, direction, and angle of the camera are all fixed, so the scene in the image collected by the camera is also determined. However, as the light intensity of the environment where the camera is located is different, the color of the brightness center of the signal light in the image collected by the camera will show different performances. When the light intensity of the environment where the camera is located is too low, the signal light will appear very bright, and the camera will adjust the exposure gain of the sig...

AI Technical Summary

Problems solved by technology

[0004] However, since the existing technology does not enhance the color of the signal light on the image captured by the camera according to the actual pixels of the signal light on the image captured by the camera, it is not suitable for the processing of all signal light images with color distortion

Moreover, the pre-stored template used in the prior art covers the image of the signal light, which will further cause the color of the signal light in the processed image to be distorted.
