Metro construction rail car signal lamp and environment brightness detection device

Abstract

The invention discloses a metro construction rail car signal lamp and environment brightness detection device, wherein the metro construction rail car signal lamp and environment brightness detectiondevice comprises a rail car head end, a high-definition camera is mounted at the top of an external side of the rail car head end, and an image processor, a display screen, a first attention device and a second attention device are mounted at the inside of the rail car head end. According to the metro construction rail car signal lamp and environment brightness detection device provided by the invention, by starting from the point of view of intelligent video monitoring, and taking machine vision as a basis, and based on video image processing related technologies and algorithms, aiming at specific structure characteristics of the rail car and analysis on operating and working characteristics of the rail car, a state of a signal lamp in front of an operation direction of the rail car and sudden change of lighting intensity of the inside of a tunnel are acquired in real time through the camera mounted at the top of an engine, images acquired are processed and analyzed automatically, a corresponding safety detection model is built, consequently, the rail car can detect the state of the signal lamp in front of the rail car and the sudden change conditions of the lighting intensity inan operating process, and intelligent pre-warning can be executed for a result of detection, thus, safety of the rail car in a traveling process is guaranteed.

Description

technical field [0001] The invention relates to a detection device, in particular to a detection device for a subway construction track car signal lamp and ambient brightness. Background technique [0002] Urban rail transit signal is a technology applied in the rail transit system to realize traffic command and rail car operation safety interval control, which is used to ensure traffic safety and improve transportation efficiency. [0003] First of all, signal lights are the most common identification objects. Traditional signal light identification methods include the identification of signal lights in gray space and the identification of signal lights in RGB space. Since the grayscale image only uses 256 levels of grayscale to describe the color information, it is inevitable that the color information will be lost during the conversion process from color to grayscale. If a signal light can display two colors, and the gray values ​​of these two colors are similar, the ide...
