摘要在国内制材行业中，制材厂对原木形状的检测以及材积的测量计算一直采用人工检尺的方法：由人工目测每根原木的外部形状，进行分类加工；人工用卷尺或卡尺量取原木的长度和检尺直径，然后，再通过查找《材积手册》得到单根原木的材积，经过逐根检尺测量和累加计算才能得到整堆原木的材积；逐堆测量之后才能得到原木的进货量，检尺的工作量是非常大的。本课题针对我国原木检测技术的发展现状，提出采用8点检测，4点组合回归描述的方法，运用自动检测技术及计算机模拟技术，对原木输送机上运行的原木进行快速在线测量，可以提高设备的检测效率。从原木外形轮廓与制材生产之间的关联性出发，探讨和研究了原木检测机设计的原理及设计的方法，为原木检测机的设计和制造提供了理论依据，原木检测技术越来越为世界各国制材企业所重视。本论文所设计的原木检测机作为一种试验阶段的设备，在整体性能上还存在许多有待解决和改进的方面，这些将会对今后的研究工作起到促进作用。关键词：光环投影测量机；识别；自动测量；定心；回归描述ABSTRACTInourcountry,thewoodmanufactureindustryinspecttheshapeandthevolumeofthelogbymanualwork.Estimatelog’soutershapewitheyes,andthenlabelthembeforethrowingintoprocessing.Peopleusestapeandcalipertoconfirmalog’slengthanddiameterofthesection,andlookforitinthemanualtoobtainonelog’svolume.Byaccumulatingallthevolumeofthelog,thenumberofthestockcanbegottenTheworkofinspectingthelogbymanualisveryheavy.Inthispaper,thetheoryoftheeightpointinspectionandthefourpointcompoundingsimulationarepresented.Sowecanquicklymeasureandgetthelog’sexternalshapeparameteraccuratelyon-linewiththeautomaticinspectingtechniqueandcomputerstimulatingtechnique.Theequipmentcanenhanceworkefficiency.Basedontherelativityoflogshapeandproduction,thedesigntheoryandmethodoflog’sshapeinspectingequipmentarediscussed.Atthesametime,thetheoreticalbasisfordesignandmanufacturyisprovidedinthispaper.Loginspectiontechniqueisrecognizedincreasinglybylumbering.Theequipmentdesignedinthispaperisasortofexperimentfacilityandalsotherearemanyquestionandjuvenility.Allthesewillaccelerateresearchingworkforthefuture.Keywords:LogShape；Identify；AutomaticInspection；ShapeIdentify；RegressionI目录摘要.........................................................................................................................................IAbstract................................................................................................................................II第1章绪论.........................................................................................................................11.1概述............................................................................................................................11.2国内和国外原木检测机设备的发展分析................................................................11.3本课题研究的目的和意义........................................................................................41.4选题的研究内容和设计设想....................................................................................5第2章原木检测机总体设计........................................................................................62.1原木检测机总体原理介绍........................................................................................62.1.1原木检测机设计原理.....................................................................................62.1.2原木形状识别机设计方案.............................................................................62.2结...
