货品信息采集装置 技术领域
本发明涉及一种用于零售业的技术领域，具体地说，涉及一种货品信息采集装置。
背景技术
在无人超市项目中，计算机视觉技术可以根据货品外部的视觉效果识别出货品种类。计算机视觉技术的应用中，计算机需要预先采集每一种类货品的大量照片，以大量照片为样本建立货品识别模型，获取每一货品的外观信息，如形状、图案、色彩、尺寸等。在理论上，在建模时录入数据库的照片数量越多，在建模后货品识别的准确性越高，一般来说，每一货品在进入无人超市销售前都需要数千张甚至数万张不同角度不同方向的照片，如果用传统的相机或摄像头进行照片采集，费时费力，速度很慢，每件货品的拍照过程一般要持续30-60分钟，而且错误率很高。
货品在进入无人超市销售前，除了影像数据(照片)，计算机还要采集货品的重量、型号、产品号等信息，需要采集的数据类别较多，采集工序繁杂，效率低下，工作量较大。
发明内容
本发明的目的在于，提供一种货品信息采集装置，可以解决现有技术存在的人工采集货品信息耗时较多、速度较慢、人力成本高、错误率较高的技术问题。

进一步地，所述影像采集单元包括第一摄像单元和/或第二摄像单元；所述第一摄像单元包括第一镜头，朝向所述载物板上的货品；所述第一摄像单元设于所述箱体的内侧壁上；和/或，所述第二摄像单元包括第二镜头，朝向所述载物板上的货品；所述第二摄像单元设于所述箱体内侧的顶面；其中，所述第一摄像单元和/或所述第二摄像单元电性连接至所述数据处理单元。
本发明的有益效果在于，提供一种货品信息采集装置，其摄像头与货品可以在拍摄过程中自动调整相对视角和相对方向，可以在短时间内拍摄到同一货品在不同角度、不同方向的大量照片，大幅提升拍摄效率，有效节省了人力成本和时间成本。

实施例1
如图1所示，本实施例提供一种货品信息采集装置，包括箱体1，为六个箱板101围成的封闭式长方体箱体。其中，任一箱板101可拆卸式连接至其他四块箱板。在其他实施例中，箱体1也可以为正方体或圆柱体。
如图2所示，箱板101包括板体1011，在板体1011边缘处设有突出卡扣1012及卡口1013，卡口1013贯穿于板体1011的边缘处。任一所述箱板的卡扣可拆卸式卡入至另一所述箱板的卡口，使得箱体拆卸简单、携带或运输方便。
箱体1还可以包括茶色的透明窗102，嵌入至箱体1的一箱板101内，以便用户可以从箱体外面观察箱体内的工作状态。
在其他实施例中，箱体1的某一箱板上还可以包括一箱门(图未示)，用户可以在不拆除箱板的情况下，通过箱门将货品放入箱体1或从箱体1内取出。
如图3～4所示，本实施例中，位于长方体箱体1底面的箱板为箱体底板103，在箱体1内侧底面，即箱体底板103上表面，设置第一旋转装置21，包括第一转动轮211、第一电机212以及第一环形传动带213，第一转动轮211通过一第一轴承214可转动式安装至所述 箱体内侧底面；第一电机212固定至所述箱体内侧底面；第一电机212包括第一转子(图未示)，所述第一转子的中心轴线与第一转动轮211的中心轴线平行；第一环形传动带213紧绷式套设于第一转动轮211及所述转子的外侧壁，第一环形传动带213内侧壁与第一转动轮211的外侧壁及所述转子的外侧壁相切。
如图3～5所示，本实施例还包括一载物板2，水平设于第一旋转装置21的顶部，用以放置货品。当第一电机212启动时，第一电机212的转子带动第一环形传动带213顺时针转动，在第一环形传动带213的牵引下，第一转动轮211也顺时针转动。此时，第一转动轮211的第一轴承214带动第一载物板2转动，进而使得被放置于第一载物板2上的货品旋转。
在箱体1内侧顶面上设有一光源3，参见图3，用以照亮箱体1内部。光源3可以是LED灯、走珠灯、白炽灯等，使得箱体的光线均匀。
影像采集单元设于箱体1内，参见图3，用以采集所述货品的至少一影像。所述影像既可以是图片或照片，也可以是视频。所述影像采集单元包括至少一个摄像单元，在本实施例中，所述影像采集单元包括第一摄像单元301和第二摄像单元302。
第一摄像单元301设于箱体1的内侧壁上，第一摄像单元301包括第一镜头与成像板(图未示)，所述第一镜头朝向载物板2上的货品，所述第一镜头的中轴线垂直于所述成像板，收到指令后对所述货品进行拍摄处理。优选地，所述第一镜头的高度与被放置于载物板2的货品的中部的高度相同，所述第一镜头的中轴线与载物板2的中轴线之间的夹角为90度，当载物板2带动货品发生转动时，第一摄像单元301可以在水平方向上采集所述货品各个角度、多个侧面的影像数据，包括图片和/或视频。
第二摄像单元302被固定至箱体1内侧的顶面，参见图4，靠近于箱体1内侧的顶面与两个侧面处的一个角落内。第二摄像单元302包括第二镜头，所述第二镜头朝向载物板2上的货品。所述第二镜头的中轴线与载物板2的中轴线之间的夹角为20～70度，所述第二镜头可以被设置为角度可调节的，使得所述第二镜头在拍摄过程中始终对准载物板2上的货品，接收指令后对货品进行拍摄处理，当载物板2带动货品发生转动时，第二摄像单元302可以向下俯拍所述货品，采集所述货品多个角度、多个侧面的影像数据，包括图片和/或视频。
如图3、4所示，在箱体1底部设有盖板401，平行于箱体底板103，且与箱体底板103围成一电气仓4，用以放置第一旋转装置21印刷电路板402和电源装置(图未示)。电气仓4的内部高度与载物板2的高度相同或者相近，不会影响第一摄像单元301对载物板2上货品的拍摄过程。为了安装方便，优选地，盖板401、箱体底板103可以被分成两个部分，电气仓4也可以被分成两个部分，分别为第一仓41和第二仓42，第一仓41用以放置第一旋转装置21，第二仓42用以放置印刷电路板402和电源装置(图未示)。印刷电路板402通过至少 一数据线连接至一数据处理单元，所述电源装置可以为连接至外部交流电的电源适配器，也可以为电池组，为数据处理单元及印刷电路板(PCB)提供电源。
本实施例在使用过程中，用户将所述箱板安装形成箱体，将需要被拍摄的货品放置于载物板2上，开始对所述货品进行拍摄处理。所述影像采集装置具有自对准功能，当所述影像采集装置接收到拍照指令时，所述第一镜头、所述第二镜头分别朝向载物板2，同时第一旋转装置21的电机212启动，载物板2带动货品缓慢转动，第一摄像单元301、第二摄像单元302以每秒10～60帧(优选20、24、25、30帧)的速度获取货品的图片或视频，获取数千或数万张所述货品侧面或顶面在不同角度的照片，以便作为构建计算机视觉模型的样本。
适用于本实施例的货品一般为标准货品，同一种类货品的外观、尺寸都是相同或者相近似的，在同一类货品中只需对一个产品进行拍摄处理即可完成该种类货品的图片采样。第一旋转装置21至少要带动货品旋转一周，第一摄像单元301、第二摄像单元302才能获取所述货品各个角度、各个方向的影像，第一旋转装置21匀速地旋转一周需要3～90秒。若第一旋转装置21匀速地旋转一周需要60秒，第一摄像单元301、第二摄像单元302以每秒30帧的速度获取货品的图片，货品信息采集装置每分钟可以采集1800张货品图片。
所述货品信息采集装置还包括存储单元5和数据处理单元6，本实施例优选一树莓派12，其存储单元5为SD卡或MicroSD卡，其数据处理单元6为ARM处理器。如图3所示，本实施例中，树莓派12被固定安装至箱体1的侧壁上，与第一摄像单元301安装在同一壳体内，树莓派12的各种接口(如网线接口、USB接口)设于箱体1的侧壁处，且暴露在箱体外部。在其他实施例中，树莓派12也可以被设置于电气仓4内，第一摄像单元301固定式或可移动式安装于箱体1的侧壁上。
第一摄像单元301、第二摄像单元302电性连接至数据处理单元6，拍摄到的照片被实时传送到树莓派12，并存储于存储单元5中，必要时数据处理单元6可以对照片进行初步筛选，删除清晰度较低的照片。
树莓派12的存储单元5，其中存储有大量计算机可执行指令，用于执行一种货品尺寸判断方法，可以根据所述货品的影像的尺寸计算所述货品的尺寸。所述货品尺寸判断方法包括如下步骤：步骤S1距离参数录入步骤，用以录入第一镜头与所述货品前端的水平距离以及所述第一镜头与所述成像板的距离；步骤S2货品影像获取步骤，用以获取所述货品在所述成像板上形成的货品影像；步骤S3影像尺寸获取步骤，用以获取所述货品影像的尺寸；步骤S4货品尺寸计算步骤，用以根据货品影像的尺寸、所述第一镜头与所述货品前端的距离以及所述第一镜头与所述成像板的距离计算所述货品的尺寸。
树莓派12的数据处理单元6包括多个执行单元，分别用以执行每一个计算机可执行 指令，每一指令执行所述货品尺寸判断方法的一个步骤。
如图6所示，数据处理单元6的执行单元包括执行单元距离参数录入单元601、货品影像获取单元602、影像尺寸获取单元603以及货品尺寸计算单元604。数据处理单元6可以根据所述货品的影像的尺寸计算所述货品的尺寸，获取货品的长、宽、高等尺寸信息。
距离参数录入单元601用以录入第一镜头与所述货品前端的水平距离以及所述第一镜头与所述成像板的距离。货品影像获取单元602用以获取所述货品在所述成像板上形成的货品影像。影像尺寸获取单元603用以获取所述货品影像的尺寸。货品尺寸计算单元604用以根据货品影像的尺寸、所述第一镜头与所述货品前端的距离以及所述第一镜头与所述成像板的距离计算所述货品的尺寸。
载物板2设有一标识，用户在摆放货品时，可以将货品放在载物板2的标识处，使得货品前端与标识相对应，该标识中心点与第一镜头的中心点在同一水平面的投影位置的距离，即可认为是第一镜头与所述货品前端的水平距离，这是可预先测量的或者预设的。所述第一镜头与所述成像板的距离为第一摄像单元301的摄像头参数，这是已知的。所述第一镜头与所述货品前端的水平距离、所述第一镜头与所述成像板的距离都可以在设备调试过程中完成设置，并将其录入至树莓派。
当货品被水平旋转一定角度后，第一摄像单元301可以拍到不同角度的货品图片，货品尺寸计算单元604可以根据光学成像原理计算货品的尺寸，包括货品的长度、宽度和高度。如图7所示，本实施例中，若所述第一镜头到所述货品的前端距离为D，所述第一镜头焦距为f，所述货品的成像高度为h，根据光学成像原理，所述货品的真实高度为H＝h*D/f。由于货品是可以被旋转的，货品尺寸计算单元604还可以进一步地计算出货品的长度和宽度。如图7所示，本实施例还包括服务器7、扫描装置8、显示装置9、报警装置10及控制面板13，分别连接至数据处理单元6。
服务器7设于所述货品信息采集装置外部，有线式或无线式连接至数据处理单元6，由于树莓派12的存储空间有限，也可以将所述货品的影像和/或其尺寸发送至服务器7，在服务器内生成及更新货品数据库，记录货品的影像、尺寸等货品信息。货品或其包装的表面设有可识别码，如条形码、二维码等，可识别码中存储有货品信息，包括货品种类、型号、产品号、系列号、价格、产地等。
扫描装置8设于所述货品信息采集装置外部，有线式或无线式连接至数据处理单元6，用以对所述货品进行扫码处理，进而识别所述货品信息，如货品种类、型号、价格等。上述货品信息可以被传送至服务器7内，进一步完善货品数据库中的货品信息。
显示装置9设于所述货品信息采集装置外部，优选设于箱体1的外侧壁，用以显示所 述货品的信息和/或拍照进度、拍照时间等工作信息。报警装置10为一扬声器，设于箱体1的外侧壁或树莓派12的电路板上。在所述货品的影像信息采集完毕后，电机212自动关闭，第一摄像单元301、第二摄像单元302自动停止拍照。所述报警装置发出警报声，提示用户该货品的信息采集完成，提示用户可以将货品取出或者对下一个货品进行信息采集。
控制面板13设于箱体1的外侧壁，用以输入用户的控制指令，显示装置9和报警装置10都可以设于控制面板13上。所述货品信息采集装置获取用户输入的控制指令，可以控制电源为各个电气组件供电或断电，控制第一旋转装置21的电机212、第一摄像单元301、第二摄像单元302开始或停止作业。
在本实施例的使用过程中，用户先组装箱体，利用扫描装置8获取所述货品的条码信息，记录货品信息，然后将货品从箱门送入箱体，放置于载物板2上，关闭箱门，设置拍摄时间(如两分钟)，启动第一旋转装置21带动载物板2发生转动，第一摄像单元301、第二摄像单元302高速采集所述货品的影像信息，并将其传送至服务器7内。
本实施例的有益效果在于，提供一种货品信息采集装置，可以在货品自动旋转时快速拍照，在短时间内获取同一货品不同角度的大量照片，以便为构建计算机视觉模型提供足够多的图片样本，有效节省了人力物力，提高了货品招片的拍摄效率。同时，货品信息采集装置还可以用于采集货品的种类、型号、价格等其他货品信息。

称重板1101为盖板401的一部分，与载物板2在同一平面上，称重板1101平行于箱体1内侧底面，设于载物板2旁边，用以放置货品。重量传感器1102一端的下表面连接至箱体1的内侧底面，即箱体底板103，其另一端的上表面连接至称重板1101的下表面。重量传感器1102连接至数据处理单元6，重量传感器1102测量所述货品的重量数据，并将该重量数据传递至数据处理单元6。
实施例2与实施例1的另一区别特征在于，在实施例2中，树莓派12也被设置于电气仓4内，第一摄像单元301固定式安装于箱体1的侧壁上。
在本实施例的使用过程中，用户先组装箱体，利用扫描装置8获取所述货品的条码信息，记录货品信息，然后将货品从箱门送入箱体，放置于所述称重板上，重量传感器采集所述货品的重量数据，数据处理单元6可以据此记录每一货品的重量值，并将其发送至服务器7，存储于货品数据库中。
然后，用户将货品转移到载物板2上，关闭箱门，设置拍摄时间(如两分钟)，启动第一旋转装置21带动载物板2发生转动，第一摄像单元301、第二摄像单元302高速采集所述货品的影像信息，并将其传送至服务器7内。

升降装置15包括第二滑轨151、第二滑块152及第二伸缩杆153。第二滑轨151竖直式设于箱体1的内侧壁上部，第二滑块152可滑动式安装至所述第二滑轨151，第二滑块152连接至第二摄像单元302。第二伸缩杆153一端连接至第二滑块152，另一端固定连接至升降装置15的一端。第二伸缩杆153长度发生改变时，第二滑块152沿着第二滑轨151上下移动，带动第二摄像单元302升降移动，可以从多个角度采集所述货品的影像，获取更多的影像数据。
第一伸缩杆143、第二伸缩杆153可以分别电性连接至数据处理单元6，用户可以根据实际需要控制第一伸缩杆143、第二伸缩杆153的伸缩量，进而调整第一摄像单元301、第二摄像单元302的镜头角度和位置，这些调整可以发生在拍照过程之前，也可以发生在拍照过程中。
在另一实施例中，所述货品信息采集装置还可以包括一第二升降装置(图未示)，设于箱体1的内侧壁上，平移装置14被可升降式安装至所述第二升降装置，第一摄像单元301被可平移式安装至平移装置14的第一滑块142，第一摄像单元301可以被安装至平移装置14，使得第一摄像单元301可以发生水平移动和/或升降移动，可以从更多角度、更多方向拍摄货 品照片，采集更多的货品影像数据。
在其他实施例中，所述货品信息采集装置，除了包括实施例1的所有技术特征，还可以包括前文所述的平移装置14或升降装置15，平移装置14或升降装置15可以设于箱体1的内侧壁上。
本实施例的有益效果在于，提供一种货品信息采集装置，第一摄像单元、第二摄像单元可以在拍摄过程中可以水平移动和/或上下移动，在短时间内获取同一货品更多角度的大量照片。
实施例4
如图16～19所示，本实施例提供一种货品信息采集装置，包括实施例1的大部分技术特征，实施例4与实施例1的区别特征在于，实施例4并未包括第一旋转装置21，而是包括第二旋转装置22，设于箱体1内侧顶面上，第二摄像单元302被安装至一第二旋转装置22，而不是被安装至箱体1的内侧壁。
第二旋转装置22的结构与第一旋转装置21的结构类似，第二旋转装置22包括第二转动轮221、第二电机222以及第二环形传动带223。第二转动轮221通过一第二轴承224可转动式安装至箱体1内侧顶面；第二电机222固定至箱体1内侧顶面，第二电机222包括第二转子(图未示)，所述第二转子的中心轴线与所述第二转动轮221的中心轴线平行；第二环形传动带223紧绷式套设于第二转动轮221及所述第二转子的外侧壁，第二环形传动带223内侧壁与第二转动轮221的外侧壁及所述第二转子的外侧壁相切。
本实施例中，还包括一旋转板225，水平设于第二旋转装置22的顶部，当第二电机222转动时，第二电机222带动第二环形传动带223顺时针转动，在第二环形传动带223的牵引下，第二转动轮221也顺时针转动。此时，第二转动轮221的轴承224带动旋转板225转动，进而使得通过一支架226连接至旋转板225的第二摄像单元302得以旋转。
在本实施例中，载物板2及货品为静止不动的，第二旋转装置22带动第二摄像单元302在水平面上转动，从上至下对位于载物板2上的货品进行拍摄。第二旋转装置22匀速地旋转一周需要3-90秒的时间，其技术效果与实施例1类似，在此不做赘述。
在其他实施例中，所述货品信息采集装置，除了包括实施例1的所有技术特征，还可以包括前文所述的第二旋转装置22，设于箱体1内侧顶面上，第二摄像单元302被安装至一第二旋转装置22，而不是被安装至箱体1的内侧壁。在第一旋转装置21和第二旋转装置22的共同作用下，朝向载物板2上的货品的第一摄像单元301、第二摄像单元302，相对于所述货品旋转，同时进行快速拍摄，在短时间内获取同一货品更多角度的大量照片。
以上实施例中，第一摄像单元301、第二摄像单元302为普通彩色摄像头，其成本较 低，两个摄像单元的拍摄速度为每秒20～30帧。在采集信息的过程中，耗时短、速度快，可节省大量人力物力，可以有效提高货品信息采集的效率。
本发明的有益效果在于，提供一种货品信息采集装置，其影像采集单元与货品可以在拍摄过程中调整相对视角和相对方向，可以在短时间内拍摄到同一货品在不同角度、不同方向的大量照片，大幅提升拍摄效率，有效节省了人力成本和时间成本。
以上所述仅是本发明的优选实施方式，使本领域的技术人员更清楚地理解如何实践本发明，这些实施方案并不是限制本发明的范围。对于本技术领域的普通技术人员，在不脱离本发明原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本发明的保护范围。
