具体实施方式
体现本公开特征与优点的典型实施例将在以下的说明中详细叙述。应理解的是本公开能够在不同的实施例上具有各种的变化，其皆不脱离本公开的范围，且其中的说明及附图在本质上是作说明之用，而非用以限制本公开。
在对本公开的不同示例性实施方式的下面描述中，参照附图进行，附图形成本公开的一部分，并且其中以示例方式显示了可实现本公开的多个方面的不同示例性结构.系统和步骤。应理解的是，可以使用部件、结构、示例性装置、系统和步骤的其他特定方案，并且可在不偏离本公开范围的情况下进行结构和功能性修改。而且，虽然本说明书中可使用术语“之上”、“之间”、“之内”等来描述本公开的不同示例性特征和元件，但是这些术语用于本文中仅出于方便，例如根据附图中的示例的方向。本说明书中的任何内容都不应理解为需要结构的特定三维方向才落入本公开的范围内。
制造行业中，质量检查是产品质量保证的关键步骤。而纺织品主要作为成衣生产的来料，它的质量直接关系到后续裁剪流程和成衣质量。如果纺织品作为来料在生产之前被发现出现质量问题，其价格会随之降低45％-65％。因此，如何减少纺织品在生产和运输过程的质量损害成为纺织企业时刻关注的问题。然而目前在我国大部分纺织厂依旧依赖于工作人员裸眼检验来完成来料布匹织物瑕疵检测工序。这个检测过程一般是由质检人员观察经由特定光线照射在验布机上以特定速度传送的布料，通过人眼观察来发现布料上瑕疵的出现以及瑕疵的位置，大小等信息。当发现疵点后，质检人员需要停止验布机送布，然后在有观测到的瑕疵点上做标记，并根据纺织品质量评价标准对该疵点进行判定评级，同时做好纸质记录。传统的人工核验方法需要耗费大量劳动力来完成，不但检测速度慢，劳动强度大，并且受主观因素的影响，缺乏一致性和可靠性。
所以，结合新一代信息技术，设计用于智能化纺织物瑕疵检测技术对纺织行业质量检测技术的发展具有重大的意义，不仅可以推动国内纺织品行业的智能化技术的发展，还可以进一步提高了纺织品生产效率。为此，我国纺织行业已经对此进行初步的探索和尝试，如引进国外纺织品产业中已经使用先进的检测系统。但是国外检验系统一般价格昂贵，大量国内纺织企业无法承担。同时国外引进的系统与国内纺织品产业环境也不相适应，需要对系统进一步的本地化处理，无疑也提高了验布成本。因此，设计和实现一套适合本土化纺织行业使用且成本较低的纺织品瑕疵检测设备和系统成为当前纺织行业智能制造技术发展的重中之重。
图1示出了本公开的一个实施例的纺织物瑕疵检测系统的示意框图。
根据本公开的一个方面，提供一种纺织物瑕疵检测系统，包括：传动组件10、图像采集组件20、验视组件30、控制装置40和打标装置50。
其中，传动组件10，适于传输纺织物，传动组件10包括第一传动段102和第二传动段104；图像采集组件20，包括第一框架202以及设置在第一框架202内的相机阵列204，相机阵列204适于采集经过第一传动段102的纺织物图像；验视组件30，与第二传动段104相对设置；控制装置40，与相机阵列204电连接，适于接收相机阵列204采集的纺织物图像，检测到纺织物图像上具有瑕疵则生成打标指令；打标装置50，设置在传动组件10的输出端，并与控制装置40电连接，适于接收控制装置40输出的打标指令，并基于打标指令对纺织物上的瑕疵进行打标。
在该实施例中，在纺织物瑕疵检测系统上通过分别设置图像采集组件和验视组件，能够基于图像采集组件对经过第一传动段的纺织物进行图像采集，以进一步采用控制装置对纺织物图像进行检测，在检测到纺织物图像中具有瑕疵时，在纺织物的瑕疵位置进行打标，另外，在需要进行人工验视时，通过验视组件对经过第二传动段的纺织物进行人工验视，在保证放置物瑕疵检测的检测效率的同时，有利于提升纺织物瑕疵检测的可靠性。
如图2所示，在一个实施例中，传动组件10还包括：送布机构106，包括送布支座1062，第一卷辊1064、送布传动段、第一电机1066、第一传动轴1068和第二传动轴1070，送布传动段设置在送布支座1062上，并经过第一传动轴1068和第二传动轴1070，如图3所示，第一卷辊1064设置在送布传动段上，并与第一电机1066配合连接，以由第一电机1066带动第一卷辊1064转动，送布传动段和第一传动段102连接。
在该实施例中，通过设置送布机构，由第一电机驱动第一卷辊转动，结合第一传动轴和第二传动轴，由第一卷辊带动轴卷状的纺织物展开，以将待检测的纺织物由送布传动段传送到第一传动段，以由与第一传动段配合设置的图像采集组件和打标装置进行图像采集和瑕疵的打标，以保证纺织物传输和自动检测的流畅性。
在一个实施例中，第一传动段102和第二传动段104连接，传动组件10还包括：收布机构108，包括收布支座1082、第二卷辊1084、收布传动段、第三传动轴1086、第四传动轴1088和第二电机1090，收布传动段设置在收布支座1082上，第二卷辊1084设置在收布传动段上，并与第二电机1090配合连接，以由第二电机1090带动第二卷辊1084转动，收布传动段与第二传动段104连接，其中，第三传动轴1086和第四传动轴1088并排设置在收布支座1082的底部，并且第三传动轴1086设置在收布传动段和第二传动段104的连接处。
在该实施例中，通过设置收布机构，将依次经过第一传动段和第二传动段的纺织物传输大宋收布传动段时，由设置在收布传动段的第二电机带动第二卷辊转动，结合第三传动轴和第四传动轴，由第二卷辊带动将展开的纺织物恢复至初始的卷起状态，实现纺织物初始状态的自动恢复。
在一个实施例中，如图1所示，还包括：纺织物张力调节机构60，如图2所示，包括设置在第一传动轴1068与第二传动轴1070之间，并沿纵向设置的高位传感器和低位传感器602，控制装置40还用于调节第一电机1066的第一电机转速和第二电机1090的第二电机转速，其中，纺织物传动至高于高位传感器的区域，控制装置40调节第一电机转速低于第二电机转速，以减小纺织物下降过程的张力，纺织物传动至低于低位传感器的区域，控制装置40调节第一电机转速高于第二电机转速，以减小纺织物下降过程的张力，纺织物传动至低于高位传感器并高于低位传感器的区域，控制装置40调节至第一电机转速与第二电机转速相同。
在该实施例中，通过设置纺织物张力调节机构，实现对纺织物张紧度的调节，在第一传动轴和第二传动轴之间沿纵向设置两个位置传感器，即高位传感器和低位传感器，以基于纺织物进入的区域与高位传感器以及低位传感器之间的相对高度关系，确定纺织物处于下降传送区域、水平传送区域还是上升传送区域，以基于不同的区域分别调节用于送布的第一电机转速和用于收布的第二电机转速，具体地，当纺织物位置高于高位传感器，即处于下降传送，调整第一电机转速略低于第二电机转速，使放布速度低于收布速度，纺织物位置下降张力降低，当纺织物位置低于低位传感器时，调整第一电机转速略高于第二电机转速，使放布速度高于收布速度，纺织物位置上升，张力增加，当纺织物位置低于高位传感器且高于低位传感器时，第一电机保持转速与第二电机一致，纺织物位置不变，张力不变，基于上述的控制方式，即能够使纺织物能够持续处于比较张紧的状态。
在一个实施例中，控制装置40具体用于；检测到纺织物图像上具有瑕疵，提取纺织物图像上的瑕疵区域，并计算瑕疵区域的像素数量，以基于像素数量对瑕疵进行分级。
在该实施例中，通过统计瑕疵像素的数量，确定瑕疵的严重程度，具体地，可以按照像素个数的不同将瑕疵划分为四个等级，其中，第一等级瑕疵包含像素最少，为轻微瑕疵，第四等级瑕疵包含像素较多，为严重瑕疵，基于上述的分级方式，则可以进一步针对不同等级的瑕疵执行相应的处理方案，从而保证瑕疵监测和处理的可靠性。
另外，还可以通过瑕疵区域的区域边框的不同粗细确定不同等级的疵点分类等级，边框越粗表示疵点分类等级越高，从而能够便于在人工查验时了解疵点的等级。
进一步地，纺织物瑕疵检测系统还可以包括瑕疵记录模块，用于在检测到瑕疵点时，记录疵点的等级、位置和疵点区域图像，以及可以进一步包括瑕疵点信息的检索功能。
在一个实施例中，控制装置40还用于：检测到纺织物图像上具有瑕疵，计算瑕疵与纺织物的边缘之间的距离，将距离作为第一坐标；打标装置50设置在第一传动段102的末端，打标装置50包括喷印机构，喷印机构具体用于在纺织物上的瑕疵处喷涂瑕疵标识。
如图3所示，打标装置50还包括安装在第一框架202上的滑动导轨504，喷印机构502固定在滑动导轨504上，其中，瑕疵标识的颜色基于分级结果确定，瑕疵标识包括第一坐标。
在一个实施例中，控制装置40还用于：基于第一电机转速确定瑕疵的第二坐标；或纺织物瑕疵检测系统还包括：码长编码器70，与控制装置40电连接，设置在传动组件10的输出端，码长编码器70用于基于转动圈数确定瑕疵的第二坐标并发送至控制装置40；打标装置50具体还用于：接收控制装置40传输的第一坐标和第二坐标，以基于第一坐标和第二坐标确定打标位置。
在该实施例中，为了确定瑕疵的具体位置，需要确定瑕疵的横坐标和纵坐标，其中，横坐标为沿纺织物传输方向的坐标，即第二坐标，纵坐标为纺织物宽度方向的坐标，即第一坐标，第一坐标通过计算瑕疵与纺织物的边缘之间的距离确定，第二坐标可以通过第一电机转速或第二电机转速确定，也可以通过设置码长编码器确定。
具体地，通过设置码长编码器，根据码长编码器的旋转圈数换算出织物的码长信息，获取疵点在织物上的纵坐标，并在疵点所在位置的旁边或者疵点所在位置对应的织物边缘上控制喷印机构沿纵向在滑动导轨上滑动至对应的瑕疵点位置，对瑕疵点位置进行准确喷印标记。

另外，通过在第一传动段上设置水平的布料托面90，并且布料的上表面涂覆有防静电涂层，一方面，防止纺织物通过托面时产生静电，另一方面，纺织物在经过第一传动段时能够保证表面平滑。
