Embodiment Construction

[0024] The present invention will be further described below with reference to the drawings and specific embodiments.

[0025] This solution takes the red light in the signal light as an example. According to the characteristics of the red signal light in different states, the color distribution of the signal light in each state is analyzed and summarized, and further dimming processing is performed according to this rule. This method can handle The problem of red signal halo in most scenes.

[0026] Such as figure 1 As shown, a traffic signal red light halo reduction system based on an embedded system includes a high-definition digital camera, an embedded system image processing unit, and a computer. The high-definition digital camera and traffic signal lights are respectively arranged at both ends of a traffic road junction The high-definition digital camera is connected to the computer, the embedded system image processing unit is connected to the computer, and the embedded syst...

Abstract

The invention discloses a system and method for halo weakening of a traffic signal red light based on an embedded system. The system comprises a high-definition digital camera, an embedded system image processing unit and a computer, wherein the high-definition digital camera is connected to the computer; the embedded system image processing unit is connected to the computer; and the embedded system image processing unit processes a halo around the red light in an acquired image. The scheme can carry out regional detection and the effective weakening or even filtering of the red halo generated by the traffic red light in an acquired video or the acquired image, so that image quality in a monitoring field is improved, and image pre-processing is completed for methods such as subsequent signal light state judgment.

Description

Technical field [0001] The invention relates to image recognition and image processing technology in the field of intelligent traffic video monitoring, in particular to a traffic signal red light halo reduction system and method based on an embedded system. Background technique [0002] In the field of video surveillance, high-definition digital cameras are more and more widely used, and the image quality of high-definition digital cameras has become more and more important. Due to the influence of the sensor, lens, etc., when the signal light in the monitoring scene is on, a circle of light similar to the color of the signal light will be scattered around the light, and the image will form a halo in the image, such as when the red light in the signal light is on At the beginning, a circle of red pixels will appear around the red light. These halos will conceal the information around the signal light. In worse cases, the shape of the signal light will become blurred. If the halo...
