摘　　要：标线对于车辆行驶具有重要的指引意义,道路标线在使用中会不断磨损,需要及时检测、修补,人工检测效率低下,本文以M A T L A B为仿真平台,设计了基于图像处理的道路标线破损自动检测系统。研究数字图像处理技术对标线的破损检测,通过搜索标线最大外边界,确定原始标线区域和破损区域,采用像素比率方法对标线的破损程度进行检测与评估,通过对多张道路图像测试,证明了该方法快速、简单、准确。The automatic detection and marking of damage has important guiding significance for vehicle driving.The road marking will be constantly worn in use,and needs to be detected and repaired in time.Manual detection efficiency is low.In this paper,taking MATLAB as the simulation platform,a road marking damage automatic detection system based on image processing is designed.This paper studies the digital image processing technology to detect the damage of the marking line.By searching the maximum outer boundary of the marking line,the original marking area and the damaged area are determined.The pixel ratio method is used to detect and evaluate the damage degree of the marking.The method is proved to be fast,simple and accurate by testing several road images.
