本科毕业设计（论文）基于人脸识别的疲劳驾车检测系统的研究本科毕业设计（论文）基于人脸识别的疲劳驾车检测系统的研究学院（系）：电气工程学院专业：测控技术与仪器学生姓名：学号：指导教师：答辩日期：摘要I摘要近些年由于人们的生活节奏快，工作压力大，因疲劳问题而引起的事故时有发生，疲劳驾驶而酿成的惨剧更是使我们警钟长鸣。为了解决这个问题，本次毕业设计着重讨论一种基于ASM模型的人脸识别算法和一种疲劳驾驶的面部特征判定标准。本文的主要内容是：首先，简要介绍此次研究的课题意义，再介绍人脸识别和疲劳检测的一些相关的背景知识，由于此次课题是疲劳驾驶的检测，所以介绍的重点是关于疲劳驾驶的检测研究。其次，讨论疲劳的判定方法，这一部分主要是对疲劳特征的选择研究，涉及到人眼睛和嘴的形状的疲劳特征分析，然后进行疲劳分析的综合。然后，详细介绍ASM模型的定义，在这一部分中还介绍了ASM的算法、区域收敛方法以及判定收敛的依据，另外，在这部分中将给出算法实现步骤的流程图。再后，主要内容是图像处理与识别，其中包括图像的预处理和手工描点方法所需要确定的参量，以及如何用matlab程序得到这些参量。程序的流程图也在这一章展示。关键词人脸识别；疲劳检测；疲劳特征；动态形状模型摘要IIAbstractRecentlyasthefastpaceoflifeandheavyworkpressure,accidentscausedbyfatiguehappenedfrequently.Trafficaccidentdisasteriscausingthebellstoring.Tosolvethisproblem,thegraduationprojectfocusedonafacerecognitionalgorithmbasedonASMmodelandafacialfeaturesdeterminationstandardsoffatiguedriving.Themaincontentsare:First,thereisabriefintroductionoftheresearch,therelevantbackgroundknowledgeoffacerecognitionandfatiguetestingwillbegivenlater.asitisthedetectionoffatiguedrivingthatwearetakingcareof,wewillmainlyfocusontheit.Secondly,wewilllearnthejudgingmethodsoffatigue,thepartchoiceofthefatiguecharacteristicsisstudiedhere,thefatiguecharacteristicsofeyesandmouthisanalyzed,thenwewillcomprehensivelyanalysisthem.Then,theprincipleandmethodofASMpersonfacerecognitiontechnologyisstudied.Inthissection,wewilldescribetheASMalgorithm,thecovergencemethodandthebasisofdeterminingconvergence.Theflowchartofalgorithmwillalsobegivenflowchartinthispart.Finally,wewillshowpicturepre-treatmentmethodsandpicturerecognition,thispartincludestheimagepre-processing,theneededparametersandhowtousethematlabprogramtogettheparameters.Theideaandflowchartofthemainprogramwillbegiven.KeywordsFaceRecognition;FatigueDetection;FatigueCharacteristics;ActiveShapemodelsIII目录摘要.......................................................................................................................IAbstract................................................................................................................II第1章绪论......................................................................................................11.1课题背景和意义..................................................................................11.2研究现状..............................................................................................31.3本文主要研究内容..............................................................................6第2章疲劳分析和疲劳检测..........................................................................82.1疲劳驾驶特征综述..............................................................................82.2具体特征分析......................................................................................92.2.1疲劳驾驶眼部特征分析..............................................................92.2.2疲劳驾驶嘴的特征分析............................................................102.2.3原始数据的获取........................................................................122.3眼睛和嘴特征的综合分析................................................................132.4本章小结............................................................................................14第3章ASM人脸识别算法..........................................................................153.1ASM模型的定义..............................................................................153.2ASM人脸识别的优势......................................................................153.2.1ASM搜索算法的特点..............................................................153.2.2几种识别方式对比分析............................................................163.3ASM的模型建立..............................................................................173.4ASM模型的搜索算法......................................................................193.5流程设计思路....................................................................................223.6本章小结............................................................................................23第4章图像处理和识别................................................................................244.1图像预处理的必要性........................................................................244.2常用光照预处理技术........................................................................244.2.1基于直方图的预处理方法........................................................254.2.2线性变换....................................................................................254.2.3对数变换....................................................................................26IV4.2.4指数变换....................................................................................274.2.5光照预处理方法选择................................................................274.3图片选取策略....................................................................................284.4图像手工描点的实现........................................................................284.4.1要确定的要素分析....................................................................284.4.2要素值的确定方法....................................................................294.5选点策略................................................
