Description

一种商品扫码设备 技术领域
本发明涉及计算机技术领域，具体而言，本发明涉及一种商品扫码设备。
背景技术
随着科技的不断发展，无人超市、无人便利店等应用而生。在无人超市中用户可以自主对商品进行选购、结账等，简化了购物流程，提高了用户的购物体验；对于商家，由于无需雇用店员对商品进行管理和收费，节约了大量的人力资源。
虽然无人超市给用户带来了很多便利，但仍存在一些问题。现有的超市中，通常店员会对用户购买的商品进行一一核验，确保顾客对所有选购的商品进行付款；而无人超市中没有店员管理，因此有时无法确保用户对所有选购的商品都进行付款，从而给商家带来损失。
因此，目前需要一种商品扫码设备，使得在无人超市中实现对用户购买的商品进行智能核验的效果，从而减少商家的损失。
发明内容
鉴于上述缺点，本发明提供了一种商品扫码设备，使得在无人超市中实现对用户购买的商品进行智能核验的效果，从而减少商家的损失。

下面结合附图具体介绍本发明各实施例的技术方案。
实施例1
基于相同的发明构思，本发明实施例提供了一种商品核验方法，该方法的流程示意图如图1所示，具体包括以下步骤：
S101：获取各待核验商品对应订单中包含的第一商品信息。
S102：采集任一待核验商品的图像，并依据采集到的该待核验商品的图像确定该待核验商品的第二商品信息。
S103：将该待核验商品的第二商品信息在第一商品信息中进行比对，以对该待核验商品进行核验。
在无人超市中应用本发明实施例，当用户购买商品后，通过采集用户实际购买的各商品的图像，从而获得各商品的商品信息(第二商品信息)，再将该商品信息与该用户订单上的商品信息(第一商品信息)进行比对，从而确定用户拿出的商品是否全部已付款，以确保不会出现未付款的商品或者拿错的商品被带出；实现了对用户购买商品进行智能核验的效果，减少了商家的损失，同时完善了无人超市的体系。
另外，目前在有店员的超市、便利店等购物场所，通常店员会在出口处对顾客所持有的订单进行核验，以避免顾客误拿商品或没有付款等情况发生。
现有技术中核验商品的方法主要依靠人为核对的方式，对顾客的订单进行核查。但通常情况下，一个顾客购买的商品数量很多，工作人员需要通过一一核查顾客实际购买的商品与订单上的商品是否一致，显然工作量较大；而且大大浪费了顾客购买商品的时间，降低了顾客的购物体验。另外，在同一时间段购物的顾客数量也会很多，这时，工作人员通常不会采取一一核查的方式对每个顾客的订单进行核查，只是粗略的估计顾客购买的商品数量与订单上的数量是否一致，这样，核验的误差较大，达不到有效的核验效果。
在上述应用场景下，应用本发明实施例，同样可实现对用户购买商品进行智能核验的效果，减少了店员的核验工作量，且提高了核验的效果。
以下针对上述S101～S103的具体实现做进一步的说明。在具体说明各个步骤之前，需要说明的是：以下对于方案的描述所涉及“无人超市”的应用场景，只是为了方便说明本发明实施例而进行的示例性的说明；在实际应用中，相关的应用场景还可能是“无人便利店”、“无人商场”等等，因此并不能认为是对本发明应用场景的具体限定。
S101：获取各待核验商品对应订单中包含的第一商品信息。
在本步骤中，获取用户购买商品对应订单上的第一商品信息，这里的第一商品信息包括：商品的名称、数量、编号等。
对于无人超市，用户先通过终端设备(例如，手机)上安装的购物APP进行商品选购，选购商品的方法具体可包括：用户通过点击该购物APP中相应商品对应的图标选定要购买的商品；或者用户使用该购物APP的扫码功能，对选购的商品上的图形标识码进行自主扫码，从而选定要购买的商品，这里的图形标识码包括条形码或二维码。当用户选定要购买的商品后，对这些商品进行线上付款；当付款完成后，客户端会自动将该用户选购商品的商品信息(即：第一商品信息)上传至服务器，服务器根据接收到的商品信息生成该用户的订单。对于有店员的超市，店员通过扫码设备(例如：扫描枪)对用户购买的商品上的图形标识码进行扫码操作，识别出用户购买商品的第一商品信息，并将第一商品信息上传至服务器；服务器接收到该第一商品信息后，生成该用户的订单。
S102：采集任一待核验商品的图像，并依据采集到的该待核验商品的图像确定该待核验商品的第二商品信息。
在本步骤中，获取待核验商品的第二商品信息的方式有很多种，例如，在第一种实施方式中，获取第二商品信息的方式为：依据采集到的该待核验商品的图像识别该待核验商品的图形标识码，并依据识别到的图形标识码确定该待核验商品的第二商品信息。在第二种实施方式中，对采集到的该待核验商品的图像进行图像识别，以确定该待核验商品的第二商品信息。
对于上述第一种获取第二商品信息的实施方式，依据待核验商品的图像识别该待核验商品的图形标识码的方式具体包括：将采集到的该待核验商品的图像切分成多个区域；计算各区域图像的图像特征信息，并将计算出的图像特征信息与预置的图形标识码的图像特征信息进行比较，以确定各区域图像是否存在图形标识码；若确定出任一区域图像中存在图形标识码，以该任一区域图像的预设位置为中心在待核验商品的图像中进行扩展识别，得到图形标识码。
在实际应用中，将该待核验商品的图像切分成多个区域，而该待核验商品的图形标识码可能只分布在个别区域中，如果逐个计算各区域图像的图像特征信息，直到确定出图形标识码的位置可能会消耗相对较长的时间。针对该问题，本发明实施例中可以并行计算各区域图像的特征信息，并将计算出的图像特征信息与预置的图形标识码的图像特征信息进行比较，从而迅速地确定各区域图像是否存在图形标识码，进而迅速地确定出图形标识码所在的位置。
优选地，对于上述实施方式，可以先将采集到的该待核验商品的图像进行二值化处理；将二值化后的该待核验商品的图像切分成多个区域。这里对图像进行二值化处理具体是将图像上的像素点的灰度值设置为0和255，使得整个图像呈现黑白的效果，突显出图像的轮廓。应用该实施方式所获得有益效果为：将待核验商品的图像进行二值化处理，减少了图像的数据量，进而减少了处理数据(例如：计算图像的特征信息)的任务量，节约了资源。
上述各区域图像的图像特征信息包括：梯度变化信息和/或敏感流变化信息；具体地，上述确定各区域图像是否存在图形标识码的方法具体为：计算各区域图像的梯度变化信息和/或敏感流变化信息，并将计算出的梯度变化信息和/或敏感流变化信息与预置的图形标识码图像的梯度变化信息和/或敏感流变化信息进行比较，以确定各区域图像是否存在图形标识码。
对于本实施方式，在将待核验图像中各区域图像的图像特征信息与预置的图形标识码的图像特征信息进行比较时，除了可确定出存在图形标识码的区域，还可以确定出该图形标识的类型；接着，根据该图形标识码的类型确定出预设的解码规则；根据该预设解码规则对该图形标识码进行解码处理，以获得待核验商品的第二商品信息。这里的第二商品信息包括：商品的名称、编号等。
对于上述第二种获取第二商品信息的实施方式，对采集到的该待核验商品的图像进行图像识别，以确定该待核验商品的第二商品信息。具体地，可以识别该待核验商品的图像上的字符或商标(logo)等，从而获取该待核验商品的第二商品信息。例如，通过采集待核验商品的图像，识别出该图像中出现字符为“XX饮料”；再根据该字符，确定出该待核验商品的第二商品信息。
以上两种获取待核验商品的第二商品信息的实施方式只是实例性的说明，本发明实施例对此不作具体限定。
S103：将该待核验商品的第二商品信息在第一商品信息中进行比对，以对该待核验商品进行核验。
在本步骤中，当确定出待核验商品的第二商品信息后，将第二商品信息在S101中获取的第一商品信息中进行比较，以对该待核验商品进行核验。
具体地，当该第二商品信息出现在第一商品信息中，说明用户对该核验商品已经付款，即：该待核验商品通过核验；当该第二商品信息没有出现在第一商品信息中，说明用户没有对该核验商品进行付款，即：该核验商品未通过核验。在对第二商品信息进行核验时，还要考虑待验商品的数 量，例如，若第一商品信息中包含有5瓶XX饮料，待核验的商品中有6瓶XX饮料，多余的一瓶XX饮料为未通过核验的商品。
在实际应用中，例如，在无人超市的应用场景下，当确定用户选购的商品均已通过核验后，可以通过控制智能锁为该用户开门，使得该用户完成本次购物；若确定用户选购的商品中存在没有通过核验的商品后，提示用户对该未通过核验的商品进行付款；当用户付款后再对该未通过核验的商品进行核验，直到该用户选购的所有商品均已通过核验后，控制智能锁为用户开门。
这里也只是示例性地说明一种应用场景，本发明实施例对此不作具体限定。
为了更加清楚的说明本发明实施例，下面通过一个完整的实例来进一步说明，该实例的流程图如图2所示，具体包括以下步骤：
S201：获取用户购买商品的订单。
S202：检查订单为空，若是，则核验完成；若否，检查该订单中是否有未核验商品或需要重新核验的商品(S203)，若有，则对该待核验商品进行图像采集，并自动对该图像中的条码进行定位(S204)；识别该条码(S205)，若该条码可以被识别，检测识别出商品信息是否在订单中(S206)，若在，则该待核验商品通过核验，若不在，则该待核验商品核验失败；若该条码无法被识别，则可以对该待核验商品进行重新核验(即：重复执行S204～S206)，或者采用人工扫码的方式对该条形码进行识别，等等，直到确定出核验结果。
实施例2
基于相同的发明构思，本发明实施例提供一种商品核验设备，该设备的结构示意图如图3所示，该装置具体包括以下部件：
传送带301和条码识别箱302；其中，条码识别箱302中设置有第一图像采集设备303和处理器；
传送带301用于将各待核验商品依次传送到条码识别箱302；
第一图像采集设备303用于采集各待核验商品的图像，并将采集到的 图像发送至处理器；
处理器用于执行以下步骤：
获取各待核验商品对应订单中包含的第一商品信息；
接收第一图像采集设备303采集的任一待核验商品的图像，并依据采集到的该待核验商品的图像确定该待核验商品的第二商品信息；
将该待核验商品的第二商品信息在第一商品信息中进行比对，以对该待核验商品进行核验。
在实际应用中，当用户购买商品后，将购买的商品(待核验的商品)依次放在本发明实施例提供的商品核验设备的传送带上；传送带将各核验商品依次传送到条码识别箱中，接着，商品核验设备中的图像采集设备对待核验商品进行图像采集，并将采集到的图像发送至处理器；处理器根据该图像获得第二待核验商品的第二商品信息，并将该第二商品信息与该用户订单上包含的商品信息(第一商品信息)进行比较，从而完成对待核验商品的核验。
在无人超市中应用本发明实施例，在用户购买商品后，通过条码识别箱采集用户实际购买的各商品的图像，从而获得各商品的商品信息，再通过处理器将该商品信息与该用户订单上的商品的信息进行比对，从而确定用户拿出的商品是否全部已付款，以确保不会出现未付款的商品或者拿错的商品被带出；本发明实施例提供的商品核验设备实现了对用户购买商品进行智能核验的效果，减少了商家的损失，同时完善了无人超市的体系。
与应用实施例1所获得有益效果相同，将本发明实施例应用在有店员的超市、便利店等购物场所中，同样可实现对用户购买商品的智能核验，从而减少了店员的核验工作量，且提高了核验的效果。
上述处理器执行商品核验的具体步骤与实施例1中的商品核验步骤一致，为避免重复，这里不再详细说明。
在实际应用中，用户将待核验商品放在商品核验设备中的传送带时，可能该待核验商品的图形标识码位于与传送带接触的位置。针对该情形，本发明实施例中的传送带可以采用两条透明传送带；在一种实施方式中，在这两条透明传送带之间设备第二图像采集设备，该第二图像采集设备用 于采集各待核验商品的图像(即：与传送带接触位置处的图形标识码)，并将采集到的图像发送至所述处理器。
在另一种实施方式中，在该两条透明传送带之间设置有激光扫码设备，该激光扫码设备用于识别各待核验商品的图形标识码以获得第二商品信息，并将该第二商品信息发送至处理器。优选地，为了节省处理器确定待核验商品的图形标识码位置的时间，用户在传送带301上放置待核验商品时，直接将有图形标识码的一面与传送带301接触。这样，无需第一图像采集设备303再对待核验商品其它位置处的图像进行采集，节约了处理器处理图像以及确定图形标识码的时间，进而提高了商品核验的效率。
在一种优选的实施方式中，本发明实施例提供的商品核验设备还包括显示屏304，显示屏304用于显示所述第一商品信息、第二商品信息和/或各待核验商品的核验结果。优选地，显示屏304可以动态地显示各核验商品的核验结果。例如，若识别出来的第二商品信息在订单中第一商品信息中，则从第一商品信息中去掉相应商品信息或扣减相应商品的数量。在商品核验设备中设置显示屏可以使用户随时获知商品的核验情况，提高用户体验。
在另一种优选的实施方式中，本发明实施例提供的商品核验设备还包括核验通过区305和核验未通过区306；核验通过区305用于接收传送带301传送的通过核验的商品；核验未通过区306用于接收传送带301传送的核验失败的商品。在实际应用中，在对商品进行核验后，位于核验通过区305中的商品是用户可以带走的商品，而位于核验未通过区306中的商品是用户不可以带走，或者是需要用户重新核验的商品。
本发明实施例提供的商品核验设备还包括手动扫码区307，动扫码区307用于用户手动对各待核验商品的图形标识码进行扫码，以确定各待核验商品的第二商品信息。在实际应用中，有些商品的图形标识码可能部分损坏或者发生折叠等，导致第一图像采集设备303无法采集到完整的图形标识码的图像，进而导致处理器无法识别该图形标识码得到第二商品信息，即使该待核验商品已经付款仍出现核验失败的情况。这时，用户可以将该待核验商品的图形标识码在手动扫码区307进行重新扫描，从而获取 该待核验商品的第二商品信息。设置手动扫码区的有益效果为：无需用户再通过传送带和条码识别箱对该待核验商品进行重新核验，简化了核验商品的流程。
在实际应用中，用户可以根据需要自行设置传送带301的传送速度、第一图像采集设备303的拍照时间或拍照位置等参数，使得传送带301与第一图像采集设备303和处理器之间协同工作，完成对各待核验商品进行核验的任务。
实施例3
基于相同的发明构思，本发明实施例一种商品扫码设备，该设备的结构示意图如图4所示，该装置具体包括以下部件：
传送带401、传感器402、第一图像采集设备403、光源404和处理器；
传送带401用于将各待扫码商品依次传送到图像采集区域；
传感器402用于当检测到有待扫码商品进入图像采集区域后，向处理器发送电信号；
第一图像采集设备403用于采集各待扫码商品的图像，并将采集到的图像发送至处理器；
光源404用于为第一图像采集设备403在采集图像时提供光源；
处理器用于执行以下步骤：
接收传感器402发送的电信号，并根据该电信号调节光源404，以及控制第一图像采集设备403对该待扫码商品进行图像采集；
接收第一图像采集设备403采集的任一待扫码商品的图像，并依据采集到的该待扫码商品的图像确定该待扫码商品的商品信息。
在实际应用中，用户将购买的商品(待扫码商品)依次放在本发明实施例提供的商品扫码设备的传送带上；传送带将各待扫码商品依次传送到图像采集区域中，当任一待扫码商品进入图像采集区域后，向处理器发送电信号；处理器接到该电信号后，控制商品扫码设备中的图像采集设备对各待扫码商品进行图像采集，并将采集到的图像发送至处理器，以及调节 光源，使得光源配合图像采集设备进行图像采集；处理器接收第一图像采集设备采集的任一待扫码商品的图像，并依据采集到的该待扫码商品的图像确定该待扫码商品的商品信息。本发明实施例中处理器依据采集到的该待扫码商品的图像确定该待扫码商品的商品信息，与实施例1中依据采集到的待核验商品的图像确定该待核验商品的第二商品信息的方法(S102)相同或类似，本发明实施例对此不再赘述。
在实际应用中，用户将待扫码商品放在商品扫码设备中的传送带时，待扫码商品的图形标识码可能位于与传送带接触的位置。针对该情形，本发明实施例中的传送带可以采用两条透明传送带，在这两条透明传送带之间设备第二图像采集设备，该第二图像采集设备用于采集各待扫码商品的图像，并将采集到的图像发送至所述处理器。在另一种实施方式中，在该两条透明传送带之间设置有激光扫码设备，该激光扫码设备用于识别各待扫码商品的图形标识码以获得各待扫码商品的商品信息。
在一种优选的实施方式中，传感器402具体为红外线发射传感器4021和红外线接收传感器4022；红外线发射传感器4021和红外线接收传感器4022用于当检测到有待扫码商品穿过红外线发射器4021发射的红外线后，向处理器发送电信号，使得处理器根据接收到的电信号调节光源404，以及控制第一图像采集设备403对该待扫码商品进行图像采集。
优选地，本发明实施例提供的商品扫码设备包括两组红外线发射传感器4021和红外线接收传感器4022，分别设置在图像采集区域的入口处和出口处。具体地，在一种实施方式中，位于入口处的红外线发射传感器4021和红外线接收传感器4022用于当待扫码商品进入图像采集区域后，向处理器发送电信号；处理器在接收到该电信号后控制第一图像采集设备403对该待扫码商品进行图像采集，以及调节光源404，这里调节光源404可包括：开启光源，或者增大光源404的亮度，配合第一图像采集设备对待扫码商品的图像进行采集。
在另一种实施方式中，位于出口处的红外线发射传感器4021和红外线接收传感器4022用于当待扫码商品离开图像采集区后，向处理器发射电信号；处理器在接收到该电信号后控制第一图像采集设备403停止对该 待扫码商品进行图像采集，以及调节光源404，这里调节光源404可包括：关闭光源，或者减小光源404的亮度。
以上两种实施方式只是示例性的说明，在实际应用中还会有很多种实施方式。例如，在又一种实施方式中，对光源404的调节可以设置预时间，比如，设定相邻两个待扫码商品进入图像采集区的时间，当相邻两个待扫码商品进入图像采集区的时间在预设时间范围之内，光源404可以一直处于开启的状态；当相邻两个待扫码商品进入图像采集区的时间超过预设时间范围，可以关闭光源404，直到有待扫码商品进入图像采集区后重新开启光源404，等等。
优选地，本发明实施例提供的商品扫码设备中的第一图像采集设备403包括至少4个摄像头。光源404包括至少4个条形光源，该至少4个条形光源分别为该至少4个摄像头提供拍照光源。具体如图5所示，若待扫码商品的图形标识码位于除与传送带接触的位置以外，可通过至少4个摄像头(摄像头A、B、C、D)对待扫码商品进行全面的图形采集，从而确定出该待扫码商品的图形标识码位置。在实际应用中，可根据实际情况安置摄像头和光源的位置，只要保证摄像头可以全面地采集到待核验商品的图像，以及光源可以配合摄像头采集到清新的图像即可。
本发明实施例提供的商品扫码设备还包括驱动电机405和底座406，其中，驱动电机405用于为传动带401提供出传送动力，底座406用于承载传送带401、传感器402、第一图像采集设备403、光源404、驱动电机405和处理器等部件。
需要说明的是：本发明实施例中的商品扫码设备可应用在实施例2中的商品核验设备中用于对待核验商品进行核验；或者本发明实施例可单独作为扫码设备，只用于对待扫码商品进行扫码得到商品信息；本发明实施例对商品扫码设备的应用场景不进行具体限定。
