I货运车辆车道偏离预警系统研究摘要车道偏离预警系统(LDWS)是智能汽车与安全驾驶系统的重要组成部分,当驾驶员所所驾驶的车辆发生了一定程度上的偏离或者车辆行驶的路径发生了一定程度上的偏离时,车辆的车道偏离预警系统可以通过发出信号的方式来及时的提示并警告货运车辆驾驶员,减少或者有效避免因为一定的车道偏离而可能引发的交通事故。文章通过对货运车辆道路安全现状的分析阐述了货运车辆车道偏离预警系统研究的意义，介绍了货运车辆车道偏离预警技术国内外现状以及货运车辆车道偏离预警系统的组成、结构和工作流程。对车道偏离预警系统的图像处理和各种算法进行了进一步的研究。关键字：货运车辆，车道偏离预警系统，图像处理，车道线检测，偏离预警算法IIAbstractTheLaneDepartureWarningSystem(LDWS)isanimportantpartofthesmartcarandsafedrivingsystem.Whenthevehicledrivenbythedriverdeviatestoacertainextentorthepathofthevehicledeviatestoacertainextent,thevehicle'sThelanedeparturewarningsystemcanpromptandwarndriversoffreightvehiclesintimebysendingsignals,reducingoreffectivelyavoidingtrafficaccidentsthatmaybecausedbyacertainlanedeparture.Thearticleexplainsthesignificanceoftheresearchonthelanedepartureearlywarningsystemoffreightvehiclesthroughtheanalysisofthecurrentsituationoftheroadsafetyoffreightvehicles,introducesthecurrentsituationofthelanedepartureearlywarningtechnologyoffreightvehiclesathomeandabroad,andthecomposition,structureandworkprocessofthelanedepartureearlywarningsystemoffreightvehicles.Theimageprocessingandvariousalgorithmsofthelanedeparturewarningsystemarefurtherstudied.Keywords:Freightvehicle,Lanedeparturewarningsystem,ImageProcessing,Lanedetection,DeparturewarningalgorithmIII目录1前言.....................................................................11.1课题研究的背景与意义...............................................11.2国内外研究现状.....................................................21.2.1国外研究现状.................................................21.2.2国内研究现状.................................................31.3研究内容...........................................................42货运车辆运输安全现状及车道偏离预警系统组成...............................52.1货运车辆运输安全现状...............................................52.1.1公路货运现状.................................................52.1.2货运车辆安全现状.............................................62.1.3影响货运车辆道路运输安全的原因...............................62.2车道偏离预警系统组成...............................................72.2.1信息采集模块.................................................82.2.2偏离决策算法模块.............................................92.2.3人机交互模块.................................................93道路图像的预处理........................................................103.1感兴趣区域选取....................................................103.2彩色图像灰度化....................................................113.3道路图像增强......................................................133.4图像边缘检测......................................................153.5图像二值化处理....................................................164车道线检测与车道偏离预警算法............................................174.1车道线检测........................................................174.1.1确定车道线模型..............................................174.1.2Hough变换检测..............................................184.2车道偏离预警...
