具体实施方式
相关技术中，货物存储和运输过程中，为了能够实现对货物的跟踪与管理，一般是采用人工扫描货物包装上所设置的标签来获取货物的身份信息。该方法存在效率低、耗时长以及劳动强度大等缺点，基于此，本实施例提供的一种货物身份信息获取装置以及货物身份信息获取方法，可以在不需要人工扫描包装箱上的标签的前提下自动获取货物的身份信息，有效解决相关技术中所存在的效率低、耗时长以及劳动强度大的问题。
为便于对本实施例进行理解，首先对本实施例所公开的一种货物身份信息获取装置进行详细介绍。
图1是一实施例提供的货物身份信息获取装置的模块组成示意图，图2是一实施例提供的货物身份信息获取装置的结构示意图，下面结合图1和图2，对该实施例的货物身份信息获取装置进行说明。
如图1和图2所示，货物身份信息获取装置1包括：工作台31、控制器11、第一驱动器12和身份获取组件13。
工作台31被配置为支撑待识别货物，工作台31包括沿竖直方向延伸的转动轴线；第一驱动器12被配置为在控制器11的控制下，驱动工作台31绕自身转动轴线转动；身份获取组件13被配置为获取放置在工作台31上的货物的设定侧面的图像，其中，该设定侧面设有货物的识别标识；控制器11被配置为控制第一驱动器12驱动工作台31绕转动轴线转动，并在工作台31转动前、转动时或者转动后，控制身份获取组件13获取设定侧面的图像，并从设定侧面的图像中提取识别标识，以获取待识别货物的身份信息。
本实施例所提供的货物身份信息获取装置1，能够在控制工作台31转动前、转动时或者转动后，获取工作台31上放置的待识别货物的设定侧面的图像，并从设定侧面的图像中提取识别标识，以获取待识别货物的身份信息。通过本实施例的货物身份信息获取装置1可以自动获取待识别货物的设定侧面的图像，并根据设定侧面的图像中的识别标识获取待识别货物的身份信息，无需人工操作，即可实现自动获取货物的身份信息，可以有效解决相关技术中通过人工扫描条 码获取货物的身份信息所存在的效率低、耗时长以及劳动强度大等问题相关技术。
下面对待识别货物、工作台31、身份获取组件13和控制器11分别加以说明：
I：待识别货物的设定侧面粘贴或印刷有货物的识别标识，比如，货物的识别标识为一维码或二维码等。当货物放置在包装箱内时，待识别货物是指货物及容纳该货物的包装箱，待识别货物的表面是指容纳货物的包装箱的表面。
在获取待识别货物的身份信息时，待识别货物被放置在工作台31上。由于放置在工作台31上的货物可以是一个，也可以是多个货物堆叠在一起，因此为了让身份获取组件13能够获取所有货物的设定侧面的图像，要求货物在堆叠的时候，货物设置有识别标识的侧面必须暴露在外侧。
II：工作台31被配置为支撑待识别货物，工作台31具有沿竖直方向延伸的转动轴线；工作台31通过第一驱动器12与货物身份信息获取装置1的底座(图中未标识)连接，在第一驱动器12的驱动下，工作台31可绕转动轴线相对于底座转动，工作台31转动时带动该工作台31上放置的待识别货物一起转动。在一实施例中，工作台31的支撑面的面积与待识别货物的底面积相适配，其中，待识别货物可以包括一个包装箱，也可以包括整齐排放的多个包装箱，如图2所示，本实施例中，待识别货物41包括堆垛在托盘(图中未标出)上的八个包装箱411，八个包装箱411呈两层堆垛，每层的四个包装箱呈两行两列排布，从而使每个包装箱411至少有一个侧面被暴露在外，而每个包装箱411的识别标识应当设置在被暴露在外的一个侧面上。货物身份信息获取装置1还包括输送轨道32，工作台31与输送轨道32连通，输送轨道32倾斜连接在地面与工作台31之间，待识别货物可通过输送轨道32容易地送至工作台31。如图2所示，本实施例中，工作台31分别与两条输送轨道32连接，输送轨道32的第一端搭在地面上，输送轨道32的第二端与工作台31等高，工作台31的支撑面为圆形，输送轨道32包括圆弧边缘，输送轨道32的圆弧边缘和工作台31相适配。
III：身份获取组件13包括一个或多个第一成像部件131；当身份获取组件13包括多个第一成像部件131时，多个第一成像部件131呈阵列排布，例如成M行N列排布，其中，M、N均为正整数，第一成像部件131被配置为拍摄待识别货物的设定侧面的图像。
如图2所示，本实施例中，身份获取组件13包括一个第一成像部件131，货物身份信息获取装置1还包括第一支架33，第一支架33竖直设置，位于工作台31 的侧方，且与工作台31间隔设置，第一成像部件131设置在第一支架33上，且第一成像部件131的工作面面向工作台31，当待识别货物位于工作台31的支撑面上时，第一成像部件131拍摄待识别货物的与第一成像部件131的工作面相对的侧面的图像，并将该图像传送至控制器11。
IV：控制器11被配置为控制第一驱动器12及身份获取组件13工作，比如，控制器11控制第一驱动器12驱动工作台31绕该工作台31的转动轴线转动，控制器11控制身份获取组件13获取待识别货物的设定侧面的图像，并对该图像进行分析处理从而获取货物的识别标识，以获取货物的身份信息。
在具体实现的时候，由于待识别货物在堆叠的时候，可能存在多种情况：其一，待识别货物放置在工作台31上后，待识别货物的设定侧面正好面向身份获取组件13的工作面(也即，第一成像部件131的工作面)，此时不需要驱动工作台31转动，因此在工作台31转动前就能够获得设定侧面的图像，进而获取到待识别货物的身份信息；其二，待识别货物放置在工作台31上后，待识别货物的设定侧面并未面向身份获取组件13的工作面，因此需要驱动工作台31转动；工作台31转动停止后，使得待识别货物的设定侧面面向身份获取组件13的工作面，进而获取到设定侧面的图像；其三，在一实施例中，待识别货物放置在工作台31上后，待识别货物的设定侧面并未面向身份获取组件13的工作面，因此需要驱动工作台31转动；在工作台31转动过程中，控制器11控制身份获取组件13获取到待识别货物的设定侧面的图像。
另外，由于待识别货物被放置在工作台31上时，待识别货物的设定侧面的面向是不确定的，因而货物身份信息获取装置1是无法提前预知待识别货物的设定侧面是面向哪个方向的，因此，控制器11还被配置为通过以下过程控制身份获取组件13获取待识别货物的设定侧面的图像：控制身份获取组件13获取待识别货物的待检测侧面的图像，其中，待检测侧面为待识别货物的多个侧面中的一个侧面；检测所获取的待检测侧面的图像中是否包括识别标识；当检测到待检测侧面的图像中不包括识别标识时，控制第一驱动器12驱动工作台31转动设定角度，将待识别货物的另外一个侧面作为待检测侧面，重复上述步骤直至检测到所述待识别货物的待检测侧面的图像中包括所述识别标识；以及将待检测侧面作为设定侧面，将所述待检测侧面的图像作为所述设定侧面的图像。
在具体实现的时候，控制器11首先将待识别货物的任意一个侧面作为待检测侧面，如果此时该待检测侧面恰好面向身份获取组件13的工作面，则直接获 取该待检测侧面的图像；如果此时该待检测侧面未面向身份获取组件13的工作面，控制器11控制第一驱动器12驱动工作台31转动，以使待检测侧面面向身份获取组件13的工作面。在获取到待检测侧面的图像后，对该待检测侧面的图像进行识别标识检测，即检测该待检测侧面的图像中是否包括待识别货物的识别标识；如果待检测侧面的图像中不包括识别标识，则将待识别货物的另一个侧面作为新的待检测侧面，并控制工作台31转动，使得新的待检测侧面面向身份获取组件13的工作面，重复上述识别标识检测的过程；如果待检测侧面的图像中包括识别标识，则将该待检测侧面作为设定侧面，将该待检测侧面的图像作为设定侧面的图像。上述过程在从待检测侧面的图像中检测到识别标识时结束，或者直到货物的所有侧面均被检测过时结束。
在一实施例中，如果待识别货物的所有侧面均被检测后，所有侧面均没有检测到识别标识，则可能存在待识别货物在堆叠的时候，待识别货物的识别标识被遮挡住的情况，进而可以发出错误告警信息。
在一实施例中，为了能够检测到待检测侧面的面向，货物身份信息获取装置1还包括面向确定组件17，该面向确定组件17被配置为获取放置在工作台31上的待识别货物的上表面的图像。控制器11还被配置为根据待识别货物的上表面的图像确定待识别货物的待检测侧面是否面向身份获取组件13的工作面，并在待检测侧面未面向身份获取组件13的工作面时，控制第一驱动器12驱动工作台31转动，以使得该待检测侧面面向身份获取组件13的工作面。
在一实施例中，面向确定组件17包括第二成像部件171，第二成像部件171被配置为拍摄待识别货物的上表面的图像。如图2所示，货物身份信息获取装置1还包括第二支架34，第二支架34的第一端与第一支架33的上端固定连接，第二支架34的第二端向工作台31的上方延伸，并与工作台31间隔设置，第二成像部件171设置在第二支架34的第二端上。当待识别货物被放置到工作台31上时，第二成像部件171的工作面与待识别货物的上表面相对，第二成像部件171可以拍摄待识别货物的上表面的图像，并将该图像传送至控制器11，控制器11对该图像分析处理，判断待识别货物的待检测侧面是否面向身份获取组件13的第一成像部件131的工作面。
在一实施例中，当第一成像部件131有一个时，控制器11能够控制第一成像部件131获取一张待识别货物的设定侧面的图像，该设定侧面的图像包括设定侧面的所有区域。
在一实施例中，当第一成像部件131有一个或多个时，控制器13能够控制第一成像部件131获取多张待识别货物的设定侧面的子图像，并将多张子图像合成为设定侧面的图像，每一张子图像对应设定侧面的不同区域。
在一实施例中，当第一成像部件131有一个时，第一成像部件131具有沿竖直方向间隔排列的多个拍摄位置。在一实施例中，第一成像部件131的多个拍摄位置沿竖直方向等距间隔排列，控制器11控制第一成像部件131移动到不同的拍摄位置，在每一个拍摄位置获取一张与该拍摄位置对应的子图像。在一实施例中，为了能够控制第一成像部件131到达位于不同高度的多个拍摄位置，货物身份信息获取装置1还包括第二驱动器19，第一成像部件131通过第二驱动器19与第一支架33传动连接，第二驱动器19被配置为驱动第一成像部件131沿竖直方向移动，并到达位于不同高度的拍摄位置，以使第一成像部件131对应于设定侧面的不同区域；此时，控制器11还被配置为控制第二驱动器19驱动第一成像部件131沿竖直方向移动，在第一成像部件131对应于每个区域时，控制第一成像部件131获取该区域的图像。
在一实施例中，当第一成像部件131有多个时，控制器11能够控制多个第一成像部件131获取多张待识别货物的设定侧面的子图像，并将多张子图像合成为设定侧面的图像，每一张子图像对应设定侧面的不同区域。
在一实施例中，控制器11分别控制不同的第一成像部件131获取待识别货物的设定侧面的不同区域的子图像；或者，控制器11能够控制第二驱动器19驱动多个第一成像部件131移动至不同高度的拍摄位置，并能够在不同高度的拍摄位置获取设定侧面的不同区域的子图像。
图3至图5分别示出了三种实施例的货物身份信息获取装置1的结构示意图，其中，每种实施例中，货物身份信息获取装置1均包括多个第一成像部件131。
图3是另一实施例提供的货物身份信息获取装置的结构示意图，本实施例中，身份获取组件13包括的多个第一成像部件131沿水平方向间隔排列，每个第一成像部件131具有沿竖直方向间隔排列的多个拍摄位置。如图3所示，本实施例中，身份获取组件13包括三个沿水平方向等距间隔排列的第一成像部件131，也即，M等于1，N等于3，货物身份信息获取装置1还包括第三支架35，第三支架35沿水平方向延伸，三个第一成像部件131固定设置在第三支架35上。为了使第三支架35上的三个第一成像部件131能够到达位于不同高度的多个拍摄位置，第三支架35还通过第二驱动器19与第一支架33传动连接，在第二驱动器19的驱动下，第 三支架35可沿第一支架33移动，从而带动位于第三支架35上的三个第一成像部件131沿竖直方向移动，使每个第一成像部件131到达不同高度的拍摄位置；在每一个拍摄位置，每一个第一成像部件131均能够获取一张子图像。
图4是又一实施例提供的货物身份信息获取装置的结构示意图，本实施例中，身份获取组件13包括多个固定设置的第一成像部件131，多个第一成像部件131沿竖直方向间隔排列，也即，多个第一成像部件131中至少两个第一成像部件131的高度不同。如图4所示，本实施例中，身份获取组件13包括九个沿竖直方向等距间隔排列的第一成像部件131，也即，M等于9，N等于1，九个第一成像部件131固定设置在第一支架33上，每一个第一成像部件131均能够获取一张子图像。
图5是再一实施例提供的货物身份信息获取装置的结构示意图，在本实施例中，身份获取组件13包括多个固定设置的第一成像部件131，多个第一成像部件131呈矩阵式排布，也即，多个第一成像部件131中至少两个第一成像部件131的高度不同。如图5所示，本实施例中，身份获取组件13包括呈九行三列排布的二十七个第一成像部件131，也即，M等于9，N等于3，货物身份信息获取装置1还包括支撑板36，二十七个第一成像部件131固定设置在支撑板36上，支撑板36与第一支架33固定连接，每一个成像部件131均能够获取一张子图像。
另外，由于货物在工作台31上的堆叠高度一般是不确定的，当身份获取组件13包括多个第一成像部件131，多个第一成像部件131具有至少两个不同的高度时，如果采用全部的第一成像部件131获取货物的图像，可能会造成其中部分第一成像部件131所获得的子图像中没有拍摄到货物。这种情况下，如果对所有的子图像进行合成处理，就会造成控制器11计算资源以及子图像合成时间的浪费。类似的，当身份获取组件13包括一个或多个第一成像部件131，每个第一成像部件131能够在第二驱动器19的驱动下到达至少两个不同高度的拍摄位置时，如果控制每个第一成像部件131在位于每个拍摄位置获取货物的子图像，同样可能造成第一成像部件131在位于部分拍摄位置时拍摄到的子图像没有拍摄到货物，因而也存在上述问题。
为了解决上述问题，本实施例所提供的货物身份信息获取装置中，还包括高度测量部件20，高度测量部件20被配置为获取放置在工作台31上的待识别货物的高度。控制器11还被配置为控制高度测量部件20获取待识别货物的高度，并根据待识别货物的高度，控制第二驱动器19驱动身份获取组件13移动到与设定侧面的不同区域对应的位置。
当身份获取组件13包括多个第一成像部件131，多个第一成像部件131具有至少两个不同的高度时，控制器11控制与待识别货物的高度对应的第一成像部件131获取设定侧面的图像；当身份获取组件13包括一个或多个第一成像部件131，每个第一成像部件131具有至少两个不同高度的拍摄位置时，控制器11控制第二驱动器19驱动第一成像部件131移动到与待识别货物的设定侧面的每个区域对应的拍摄位置，并控制第一成像部件131在位于对应的拍摄位置时获取设定侧面的图像。
在一实施例中，在根据待识别货物的高度控制与该高度对应的第一成像部件131获取设定侧面的图像时，控制器11能够根据待识别货物的高度、每一个第一成像部件131的安装位置以及每一个第一成像部件131拍摄到待识别货物的视角范围，判断哪些第一成像部件131可以拍摄到待识别货物，从而确定可以拍摄待识别货物的设定侧面的子图像的第一成像部件131。在获取子图像时，仅仅控制上述确定的第一成像部件131开启，而其它的第一成像部件131不开启，与启动全部第一成像部件131相比，采用上述方法身份获取组件13拍摄到的子图像的数量少，因此将子图像合成图像时所使用的计算资源也少，且所耗时间也少。
同理，在根据待识别货物的高度，控制第二驱动器19驱动第一成像部件131到达与该高度对应的拍摄位置时，要根据每个拍摄位置的高度、待识别货物的高度以及第一成像部件131在每个拍摄位置的视角范围，判断第一成像部件131在哪个拍摄位置可以拍摄到待识别货物的设定侧面的子图像，从而确定可以拍摄到待识别货物的的设定侧面的子图像的拍摄位置。然后控制第二驱动器19驱动第一成像部件131依次到达上述确定的拍摄位置，并在每个拍摄位置获取待识别货物的子图像，从而得到的所有子图像中均包括了待识别货物；与控制第一成像部件131到达所有拍摄位置相比，采用上述方法身份获取组件13拍摄的子图像数量少，因此将子图像合成为图像时所使用的计算资源也少，且所耗时间也少。
另外，参见图1所示，上述实施例所提供的货物身份信息获取装置中，还包括：输入组件14、输出组件15和存储组件16。
输入组件14被配置为接收用户输入的操作信息，输入组件14可以为鼠标、机械按键，也可以为设置于触摸显示屏上的触摸按键。
输出组件15被配置为向用户输出操作信息，输出组件15可以为显示屏、语音装置等，如图2所示，本实施例中，输出组件15为显示屏，输出组件15通过显 示方式向用户输出操作信息，输出组件15与第一支架33活动连接，输出组件15的高度与工作人员的视线范围相匹配，便于工作人员查看输出组件15的显示内容。
存储组件16被配置为存储货物身份信息获取装置1的控制程序，以及存储程序运行过程中生成的数据及变量。
在一实施例中，货物身份信息获取装置1还包括物品检测部件，物品检测部件被配置为检测在工作台31上是否放置有货物。例如，该物品检测部件可以包括传感器18，传感器18检测是否有待识别货物被放置到工作台31上，传感器18可以为机械开关或重量传感器等，其中，当有待识别货物和没有待识别货物被放置到工作台31上时，传感器18输出不同的信号，比如，当有待识别货物被放置到工作台31上时，传感器18输出第一信号，当没有待识别货物被放置到工作台31上时，传感器18输出第二信号，控制器11根据传感器18输出的信号，可以判断是否有待识别货物被放置到工作台31上。本实施例中，传感器18与工作台31固定连接，位于工作台31的下方。
基于同一发明构思，本实施例中还提供了与货物身份信息获取装置1对应的货物身份信息获取方法。
图6是一实施例提供的货物身份信息获取方法的流程图，该方法主要应用于上述实施例所提供的货物身份信息获取装置，如图所示，该方法包括以下步骤：
S610中，在工作台转动前、转动时或者转动后，获取放置在工作台上的待识别货物的设定侧面的图像，其中，设定侧面设有待识别货物的识别标识。
在具体实现的时候，设定侧面为待识别货物上粘贴或印刷有货物的识别标识的侧面，货物的识别标识被配置为标识货物的身份，比如，货物的识别标识为条码。当货物放置在包装箱内时，待识别货物是指货物及容纳该货物的包装箱，待识别货物的表面是指容纳货物的包装箱的表面。待识别货物可以包括一个包装箱，也可以包括整齐排放的多个包装箱，当待识别货物包括一个包装箱时，设定侧面可能为该包装箱的任意一个侧面；当待识别货物包括多个包装箱时，多个包装箱排放在一起，形成包装箱垛，包装箱垛的每一个侧面均包括至少一个包装箱的侧面，设定侧面可能为该包装箱垛的任意一个侧面。
在获取设定侧面的图像时，具体有两种方法，其一：身份获取组件13包括至少一个第一成像部件131，通过一个第一成像部件131获取设定侧面的完整图像。其二，身份获取组件13包括一个或者多个第一成像部件131，通过一个或多 个第一成像部件131获取多张待识别货物的设定侧面的子图像；将多张子图像合成为设定侧面的图像；其中，每一张子图像对应设定侧面的不同区域。
在一实施例中，在获取多张待识别货物的设定侧面的子图像时，具有以下几种方法，其一：通过控制一个第一成像部件131移动到不同的拍摄位置，在每一个拍摄位置都获取一张子图像，并将第一成像部件131在多个拍摄位置分别获取的子图像合成为一张图像。其二，当身份获取组件13包括多个第一成像部件131时，通过多个第一成像部件131一次获取设定侧面的多张子图像，并将所有第一成像部件所获取的子图像合成为一张图像。其三，当身份获取组件13包括多个第一成像部件131时，通过控制身份获取组件13移动到不同的拍摄位置，在每一个拍摄位置，控制身份获取组件13的每个第一成像部件131均获取一张子图像，并将所有第一成像部件131在多个拍摄位置所获得的子图像合成为一张图像。
当身份获取组件13包括一个或多个第一成像部件131，每个第一成像部件131具有不同高度的多个拍摄位置时，获取多张待识别货物的设定侧面的子图像包括：驱动身份获取组件13沿竖直方向移动，以使身份获取组件13对应于设定侧面的不同区域；在身份获取组件13对应于每个区域时，控制身份获取组件13获取区域的图像。
以上述实施例的货物身份信息获取装置1为例，控制器11控制第二驱动器19驱动第三支架35沿竖直方向移动，从而使第三支架35带动身份获取组件13的每个第一成像部件131移动，使每个第一成像部件131到达不同高度的多个拍摄位置，在每个第一成像部件131位于一个拍摄位置时，控制该第一成像部件131拍摄一幅设定侧面的子图像，从而在每个第一成像部件131位于每个拍摄位置时得到一幅设定侧面的子图像，进而得到多幅设定侧面的子图像。
在一实施例中，当身份获取组件13包括多个第一成像部件131，多个第一成像部件131中至少两个第一成像部件131的高度不同时，获取待识别货物的设定侧面的图像包括：获取放置在工作台31上的待识别货物的高度；根据待识别货物的高度，控制身份获取组件13的与该高度对应的第一成像部件131获取设定侧面的图像。
在具体实现的时候，在根据待识别货物的高度控制与该高度对应的第一成像部件131获取设定侧面的图像时，控制器11能够根据待识别货物的高度、每一个第一成像部件131的安装位置以及每一个第一成像部件131拍摄到待识别货物的视角范围，判断哪个第一成像部件131可以拍摄到待识别货物，从而确定可以 拍摄到待识别货物的子图像的第一成像部件131。在控制第一成像部件131获得子图像时，仅仅控制上述可以拍摄到待识别货物的子图像的第一成像部件131开启，而其它的第一成像部件131不开启，从而所得到的所有子图像中均拍摄到待识别货物；与启动全部第一成像部件131相比，采用上述方法身份获取组件13拍摄到的子图像的数量少，因此将子图像合成为图像时所使用的计算资源也少，且所耗时间也少。
在一实施例中，当身份获取组件13包括一个或多个第一成像部件131，每个第一成像部件131具有不同高度的多个拍摄位置时，驱动身份获取组件13沿竖直方向移动，以使身份获取组件13对应于设定侧面的不同区域，其中，驱动身份获取组件13沿竖直方向移动，以使身份获取组件13对应于设定侧面的不同区域包括：获取放置在工作台31上的待识别货物的高度，根据待识别货物的高度，驱动身份获取组件13移动到与设定侧面的不同区域对应的位置。
在具体实现的时候，在根据待识别货物的高度，驱动身份获取组件13移动到与设定侧面的不同区域对应的位置时，要根据每个拍摄位置的高度、待识别货物的高度以及第一成像部件131在到达每个拍摄位置时的拍摄视角范围，判断第一成像部件131在哪个拍摄位置可以拍摄到待识别货物，从而确定可以拍摄到待识别货物的子图像的拍摄位置。然后驱动第二驱动器19驱动第一成像部件131依次到达上述确定的拍摄位置，并在每个拍摄位置获取待识别货物的子图像。从而得到的所有子图像中均包括了待识别货物；与控制第一成像部件131到达所有拍摄位置相比，采用上述方法身份获取组件13拍摄到的子图像的数量少，因此将子图像合成为图像时所使用的计算资源也少，且所耗时间也少。
S620中，从设定侧面的图像中提取识别标识，以获取待识别货物的身份信息。
获取设定侧面包含的待识别货物的识别标识，对该识别标识进行识别以获取货物的身份信息。
在一实施例中，当设定侧面中包含的识别标识不能被识别时，确定该识别标识的位置，并通过输出组件15进行报警提示。图7是根据本实施例的待识别货物的设定侧面及该设定侧面包含的识别标识的示意图，如图所示，该识别标识为条码，待识别货物的设定侧面包括呈三排两列设置的六个条码501-506，当判定条码1不能被识别时，控制器11控制输出组件15输出“第一排第一列条码不能被识别”的提示信息。
以本实施例的货物身份信息获取装置1为例，当控制器11控制第一成像部件131拍摄到待识别货物的设定侧面的图像后，对该图像进行分析处理，提取该图像中包含的货物的识别标识，对该识别标识进行识别，从而获取货物的身份信息。
本实施例所提供的货物身份信息获取装置的控制方法，能够在控制工作台31转动前、转动时或者转动后，获取工作台31上放置的待识别货物的设定侧面的图像，并从设定侧面的图像中提取识别标识，以获取待识别货物的身份信息。通过本实施例的货物身份信息获取装置的控制方法，货物身份信息获取装置可以依次自动获取待识别货物的每个设定侧面的图像，并根据每个设定侧面的图像中的识别标识获取待识别货物的身份信息，无需人工操作，即可实现自动获取货物的身份信息，可以有效解决相关技术中通过人工扫描条码获取货物的身份信息所存在的效率低、耗时长、劳动强度大等问题。
在一实施例中，获取放置在工作台31上的待识别货物的设定侧面的图像之前，货物身份信息获取装置的控制方法还包括：检测工作台31上是否放置有待识别货物。
在一实施例中，检测是否有待识别货物被放置到货物身份信息获取装置1的工作台31上，当检测到有待识别货物被放置到工作台31上时，则控制身份获取组件13获取待识别货物的设定侧面的图像，否则，继续执行该步骤。
以本实施例的货物身份信息获取装置1为例，控制器11检测是否有待识别货物被放置到货物身份信息获取装置1的工作台31上，一实施例中，货物身份信息获取装置1包括输入组件14，控制器11通过检测输入组件14接收的命令判断是否有待识别货物被放置到工作台31上，比如，当用户将待识别货物输送至工作台31上后，通过输入组件14输入货物已放置的命令，控制器11检测输入组件14接收到的命令，当控制器11检测到输入组件14接收到货物已放置的命令时，判定有待识别货物被放置到工作台31上；在一实施例中，货物身份信息获取装置1包括传感器18，控制器11通过检测传感器18输出的信号判断是否有待识别货物被放置到工作台31上，比如，当有待识别货物被放置到工作台31上时，传感器18输出第一信号，当没有待识别货物被放置到工作台31上时，传感器18输出第二信号，控制器11检测传感器18输出的信号，当检测到传感器18输出的信号由第二信号变化为第一信号时，判定有待识别货物被放置到工作台31上。
图8是一实施例提供的一种获取放置在工作台上的待识别货物的设定侧面 的图像的具体方法，如图8所示，该方法包括：
S710中，通过身份获取组件获取待识别货物的待检测侧面的图像，其中，待检测侧面为待识别货物的多个侧面中的一个侧面。
在具体实现的时候，首先将待识别货物的任意一个侧面作为待检测侧面，如果此时该待检测侧面恰好面向身份获取组件13的工作面，则直接获取该待检测侧面的图像；如果此时该待检测侧面并非面向身份获取组件13的工作面，则控制工作台31转动，使得该待检测侧面面向身份获取组件13的工作面。在待检测侧面面向身份获取组件13的工作面后，控制身份获取组件13获取该待检测侧面的图像。
在另一实施例中，参见图9所示，在控制身份获取组件13获取待识别货物的待检测侧面的图像之前，该获取放置在工作台31上的待识别货物的设定侧面的图像的方法包括：
S810中，获取放置在工作台上的待识别货物的上表面的图像。
S820中，根据上表面的图像确定待识别货物的待检测侧面是否面向身份获取组件的工作面。如果待识别货物的待检测侧面面向身份获取组件的工作面，则跳转至S710，如果待识别货物的待检测侧面未面向身份获取组件的工作面，则跳转至S830。
S830中，在待检测侧面未面向身份获取组件的工作面时，驱动工作台转动，以使得该待检测侧面面向身份获取组件的工作面。然后跳转至S710。
在具体实现的时候，以一实施例的货物身份信息获取装置1为例，为了能够检测到待检测侧面的面向，控制器11控制第二成像部件171拍摄待识别货物的上表面，控制器11对上表面的图像进行分析处理，判断待识别货物的待检测侧面是否面向身份获取组件13的工作面。如果待识别货物的待检测侧面未面向身份获取组件13的工作面，那么驱动工作台31转动，使得该待检测侧面面向身份获取组件13的工作面，之后再控制身份获取组件13获取待检测侧面的图像；如果待识别货物的待检测侧面面向身份获取组件13的工作面，则直接控制身份获取组件13获取待检测侧面的图像。
在一实施例中，以一实施例的货物身份信息获取装置1为例说明驱动工作台31转动的具体方法：在驱动工作台31转动的时候，为了能够使得工作台31转动后，待检测侧面面向身份获取组件13的工作面，一实施例中，控制器11驱动工作台31转动预设角度，以使待检测侧面面向身份获取组件13的工作面，其中， 控制器11可根据待检测侧面的当前面向以及身份获取组件13的工作面之间的相对关系，预先计算该预设角度，比如，当待检测侧面的面向与身份获取组件13的工作面的面向相同时，该预设角度为180度；当待检测侧面的当前面向与身份获取组件13的工作面的面向之间的夹角为150度时，则该预设角度为30度。一实施例中，控制器11控制第一驱动器12驱动工作台31转动，工作台31转动过程中，控制器11控制面向确定组件17的第二成像部件171拍摄待识别货物的上表面的图像，并根据所拍摄的图像判断待识别货物的当前待检测侧面是否面向第一成像部件131的工作面，当判定待识别货物的当前待检测侧面面向第一成像部件131的工作面时，控制第一驱动器12停止驱动工作台31转动。当待识别货物的待检测侧面面向第一成像部件131的工作面时，控制器11控制第一成像部件131拍摄待检测侧面的图像，并对该图像进行分析处理，提取该图像中包括的货物的身份标识，对该身份标识进行识别，从而获取货物的身份信息。
在一实施例中，以上述实施例的货物身份信息获取装置1为例，说明根据待检测货物的上表面的图像，检测待识别货物的待检测侧面是否面向第一成像部件131的具体方法：待检测侧面为待识别货物的一个侧面，控制器11控制第二成像部件171拍摄待识别货物的上表面的图像后，能够从上表面的图像中识别出货物的多个侧面，以其中一个侧面为当前待检测侧面，以身份获取组件13的第一成像部件131的主光轴为基准线，此时，如果身份获取组件13包括一个第一成像部件131，则该第一成像部件131的主光轴即为身份获取组件13的主光轴；如果该身份获取组件13包括多个第一成像部件131，多个第一成像部件131的成像中心所在的轴线，为该身份获取组件13的主光轴。根据基准线，判断待识别货物的当前待检测侧面相对于基准线是否发生偏斜，当待识别货物的当前待检测侧面相对于基准线没有发生偏斜时，判定待检测侧面面向第一成像部件131的工作面；当待识别货物的当前待检测侧面相对于基准线发生偏斜时，判定待识别货物的待检测侧面未面向第一成像部件131的工作面。图10示意了待识别货物41被放置到货物身份信息获取装置1的工作台31上时的俯视图。待识别货物41包括第一侧面4101、第二侧面4102、第三侧面4103和第四侧面4104，以及上表面4100，假设当前的待检测侧面为第一侧面4101，由于待识别货物41的第一侧面4101相对于基准线50发生了偏斜，因此，判定待检测侧面不面向第一成像部件131的工作面。
当待检测侧面未面向身份获取组件13的时候，则要根据当前待检测侧面的 面向以及待检测侧面的与基准线之间的角度，驱动工作台31转动，以使得待检测侧面面向身份获取组件13的工作面。
在一实施例中，以上述实施例的货物身份信息获取装置1为例说明控制器11确定待检测侧面的方法：控制器11在获取待检测货物的上表面的图像后，能够识别出待识别货物的每一个侧面，控制器11首先将其中任意一个侧面作为待检测侧面，并判断该待检测侧面是否面向身份获取组件13的工作面；如果该待检测侧面未面向身份获取组件13的工作面，则控制工作台31转动，以使得该待检测侧面面向身份获取组件13的工作面。当检测到当前待检测侧面并非设定侧面后，控制器11将与该当前待检测侧面相邻的另外一个侧面作为新的待检测侧面，并控制工作台31转动，以使得新的待检测侧面面向身份获取组件13的工作面，直至检测到待检测侧面为设定侧面，或者所有的侧面均被检测过为止。在一实施例中，待识别货物的所有侧面中，控制器11将该待识别货物上的与第一成像部件131的工作面所呈夹角最大的一个侧面设定为设定侧面，如图10所示，由待识别货物的上表面图像4100可以识别出待识别货物41包括的4101-4104四个侧面，其中，第一侧面4101与身份获取组件13的工作面之间的夹角最大，因此，控制器11将第一侧面4101设定为待检测侧面。
S720中，检测所获取的待检测侧面的图像中是否包括识别标识。如果待检测侧面的图像中包括识别标识，则跳转至S730，如果待检测侧面的图像中未包括识别标识，则跳转至S740。
在具体实现的时候，要对待检测侧面的图像进行识别标识检测，检测的方法可以采用图形特征对比法及像素特征提取法等多种方法对待检测侧面的图像中是否包括识别标识进行分析。
S730中，将待检测侧面作为设定侧面，该待检测侧面的图像作为设定侧面的图像。
S740中，检测待识别货物的所有侧面是否均被检测过。如果待识别货物的所有侧面未被全部检测，则跳转至S750，如果待识别货物的所有侧面均被检测过，则跳转至S760。
在具体实现的时候，控制器11会预先获知待检测货物的侧面的数量，并在每检测一个侧面时，判断待检测货物的所有侧面是否均被检测过。
S750中，将待识别货物的另外一个侧面作为待检测侧面，跳转至S710。
S760中，生成错误告警信息。
错误告警信息被配置为提示用户并未从当前放置在工作台31上的待识别货物上检测到识别标识，以提示用户调整货物的放置方法。
图10是又一实施例提供的一种获取放置在工作台上的待识别货物的设定侧面的图像的具体方法，如图10所示，该方法包括：
S710′中，通过身份获取组件获取待识别货物的待检测侧面的图像，其中，待检测侧面为待识别货物的多个侧面中的一个侧面。
S720′中，检测所获取的待检测侧面的图像中是否包括识别标识。如果待检测侧面的图像中包括识别标识，则跳转至S730′，如果待检测侧面的图像中未包括识别标识，则跳转至S740′。
S730′中，将待检测侧面作为设定侧面，该待检测侧面的图像作为设定侧面的图像，执行完该步骤后，跳转至S740′。
S740′中，检测待识别货物的所有侧面是否均被检测过。如果待识别货物的所有侧面未被全部检测，则跳转至S750′，如果待识别货物的所有侧面均被检测过，则跳转至S760′。
S750′中，将待识别货物的另外一个侧面作为待检测侧面。跳转至S710′。
S760′中，判断已获取的待检测侧面的图像中是否至少一个待检测侧面的图像包括识别标志，若至少一个待检测侧面的图像包括识别标志，则结束，若所有侧面的图像均未包括识别标志，则跳转S770′。
S770′中，生成错误告警信息。
