摘 要:为解决铁路安全运输问题,对基于机器视觉的铁路信号灯检测方法进行仿真图像和视频检测实验研究。阐述了铁路信号灯图像在不同颜色空间下的特性及其对铁路信号灯识别的影响,将其由RGB颜色空间转换为HSV颜色空间。通过Canny算子、腐蚀膨胀以及开闭运算等技术提取铁路信号灯图像的几何特征,通过Hough检测,对图像中铁路信号灯进行定位。对定位的信号灯进行颜色提取,从而识别出信号灯的类别。根据多种天气情况下的铁路信号灯图像进行仿真实验分析,进一步对采集的列车行驶视频进行实验分析,优化检测方法。研究结果表明,提出的铁路信号灯检测模型,能够支持复杂背景下的铁路信号灯类别的有效识别。通过机器视觉技术实现铁路信号灯的检测和识别,是提高铁路运输安全性的一种有效方法。In order to solve the problem of railway safe transportation,the detection experiment is carried out on simulation pictures and real videos of railway signal lamps based on machine vision.The characteristics of the image of railway signal lamps in different color spaces and its influence on the recognition of railway signal lamp are discussed.The RGB color space of railway signal image is converted to HSV color space.The geometric features of railway signal lamp images are analyzed by Canny operator,corrosion expansion and open-close operation,then the railway signal lamp is located in the image by Hough detection.The color of the positioned signal lamp is extracted,so that the type of the signal lamp can be identified.According to the simulation analysis of the images of railway signal lamps under various weather conditions,the simulation experiment is carried out to optimize the detection method by analyzing the collected train driving video.The experiment result shows the detection model of railway signal lamps can support the effective recognition of railway signal lamps under complex background.It realizes the detection and recognition of railway signal lamps based on machine vision,which provides an effective method for railway safe transportation.
