Red light color strengthening method and system of traffic lights

Abstract

A red light color strengthening method of traffic lights includes the steps that a red light image is continuously collected through imaging equipment, and a rough area containing the red light area is marked in the red light image; a historical red light area is initialized, and the historical red light area is as big as the rough area; a time model is provided, a red light presentation color model is built through a red light presentation color module building step, and the duration time is t color; within each t static and t color time, color strengthening is carried out on the rough area through the red light presentation color model and a red light color strengthening step, and the t color and the t static represents the on-line study time of the red light presentation color model and the time that the red light presentation color model can keep respectively; after each time of on-line study, the red light presentation color model is updated. When a rod for supporting the imaging equipment vibrates or shakes, the actual red light area can still be detected under the influence of natural factors, and therefore the color can be strengthened no matter how the representation color of the red light is.

Description

technical field [0001] The invention belongs to the technical field of intelligent transportation, and in particular relates to a method for enhancing the color of a traffic light and an enhancement system thereof. Background technique [0002] In the field of intelligent transportation, whether the vehicle violates the regulations depends largely on the traffic lights in the video captured by the imaging device. In actual traffic imaging, there is a certain distance between the placement of traffic lights and the imaging equipment. As the distance increases, the scattering of traffic lights by atmospheric particles becomes more serious. At the same time, natural light will also enter the imaging equipment due to scattering, resulting in the acquisition In the obtained image, the red light is yellowish and the green light is white. [0003] In the process of intelligent traffic analysis relying on video, the red light turns yellow or turns yellow will have a great impact on...

AI Technical Summary

Problems solved by technology

[0004] The current color enhancement of the red light is to draw a rectangular frame circumscribed by the red light at the corresponding position of the red light in the image, and then enhance the color of the inner area, which faces two problems: 1. The imaging equipment is generally placed on the shelf, due to wind or The ground vibration makes the shelf shake, causing the red light area reserved in the imaging device to shift, and the red light area cannot be detected well; 2. The actual color of the red light will change, such as rainy days or morning, evening and night air Humidity is high, and a large number of tiny water droplets suspended in it cause serious light scattering, and the red light is seriously yellowish, while the red light is slightly yellowish or even no color cast at noon on sunny days
