Method and device for processing signal lamp image

Abstract

The invention provides a method and device for processing a signal lamp image. The method includes the steps that S1, signal lamp marginal information in one frame of image collected through a camera is detected; S2, according to the signal lamp marginal information, a signal lamp area is segmented from the image; S3, color strengthening is performed on the signal lamp area in the image. The device comprises a marginal detecting module, an area segmenting module and a color strengthening module, wherein the marginal detecting module is used for detecting the signal lamp marginal information in one frame of image collected through the camera, the area segmenting module is used for segmenting the signal lamp area according to the signal lamp marginal information, and the color strengthening module is used for performing color strengthening on the signal lamp area in the image. The method and device for processing the signal lamp image can solve the problem that the color of a signal lamp in the collected image is distorted when illumination intensity of the environment where the camera is located 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...

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.
