本发明涉及一种射频识别终端及其使用方法，尤指一种通过图像识别技术进行信息筛选的射频识别终端及其使用方法。
背景技术
射频识别技术(Radio Frequency Identification，RFID)，是自动识别技术的一种，其通过无线射频方式进行非接触双向数据通信，利用无线射频方式对记录媒体(电子标签或射频卡等)进行读写，从而达到识别目标和数据交换的目的。一套完整的RFID系统，由读写器(Reader)、电子标签(Tag)和数据管理系统三部分组成，其工作原理是读写器(Reader)发射一特定频率的无线电波能量，用以驱动电路将内部的数据送出，此时Reader便依序接收解读数据，送给数据管理系统做相应的处理。RFID技术依靠电磁波，并不需要连接双方的物理接触，甚至高频段的RFID读写器可以同时识别、读取多个标签的内容，使得射频识别技术得到了越来越广泛的应用。
然而，由于用于射频识别的电磁波为不可视的，导致读写器在识读标签时具有盲目性，用户根本不知道读取到了哪个位置的标签。在实际使用过程中，如盘点货物时，由于不同货物有不同分区，且这些不同分区通常相隔较近，就经常会出现不小心盘点到了隔壁区位的货品，导致用户错误地认为有货物错区放置，需要清点，长此以往也导致用户无法快速确认是否有货物确实错区放置，浪费时间、效率低下。
本发明针对以上问题，提供一种新的射频识别终端及其使用方法，采用新的方法和技术手段以解决这些问题。

射频识别终端100、定向天线1、最大辐射方向X、接收范围A(A’)、触发按键3、控制单元4、显示屏5、显示区域51、摄像头6、光轴L、瞄准图案P(P’)、按钮7、待识别物品8、电子标签81。
具体实施方式
为便于更好的理解本发明的目的、结构、特征以及功效等，现结合附图和具体实施方式对本发明作进一步说明。
如图1和图2所示，为本发明一种实施例的射频识别终端100，所述射频识别终端100主要包括定向天线模块1、摄像头2、显示屏5和控制单元4。
如图3所示，所述定向天线模块1设计成可通过多种不同的接收范围A(A’)来接收信号，且不同的接收范围A(A’)均通过精确测定为已知形状，且可根据需求而通过一定的技术手段将该形状调节为规则形状，如圆形或椭圆形等。所述定向天线模块1可为阵列天线或组合天线等辐射角度或最大辐射方向X可调节的天线，使得所述定向天线模块1的接收范围A(A’)可根据需要来调节，所述定向天线模块1优选为相控阵列天线，以达到对所述定向天线模块1的辐射角度和最大辐射方向X的精确控制，从而实现对所述定向天线模块1的接收范围A(A’)的精确控制。本实施例中，所述定向天线模块1既为发射天线也为接收天线，根据天线的互易定理，所述定向天线模块1作为发射天线时的辐射范围与作为接收天线时的接收范围A(A’)相同；其它实施例中，所述定向天线模块1可仅为接收天线，从而可另外设置发射天线。
如图3和图4所示，所述摄像头2用以采集待读取区域P的图像，所述摄像头2的光轴L与所述定向天线模块1的最大辐射方向X(或最大接收方向)同轴设置或平行设置，所述定向天线模块1的接收范围A(A’)位于所述摄像头2的视场FOV内，使得所述定向天线模块1可读取的物品8均位于所述摄像头2的视场FOV内。其它实施例中(未图示，下同)，所述摄像头2的光轴L可与所述定向天线模块1的最大辐射方向X呈一定夹角。
如图1和图5所示，所述显示屏5为触摸屏，所述显示屏5上设有一个显示区域51，所述显示区域51通过线条在所述显示屏5上示出，从而形成一个显示框，所述摄像头2采集的待读取区域P的图像显示于所述显示屏5上，且所述显示区域51的形状经人为设定，使得所述显示区域51显示的范围与所述定向天线模块1的所述接收范围A(A’)大致重合，且由于所述接收范围A(A’)可调节，所述显示区域51设置成根据所述接收范围A(A’)的变化而变化，使得所述显示区域51与所述接收范围A(A’)始终保持大致重合，通过所述显示区域51可视化显示不可视的所述接收范围A(A’)，使用户明确所述射频识别终端100的识读范围。所述显示屏5用以供用户操作，以选择图像中的目标物品8。
具体来说，所述射频识别终端100可通过深度学习神经网络建立多种待识别物品8的图像库，并将图像库存储于存储单元6中以供所述控制单元4调用。当所述摄像头2采集到待读取区域P的图像并显示于所述显示屏5上，当用户选择图像中的物品8时，如点选或框选图像中的某一物品8，所述控制单元4即通过深度学习神经网络将用户选择的物品8的图像与存储单元6中的图像库进行比对，以识别用户选择的物品8。之后，所述控制单元4将所述定向天线模块1接收的信号中，用户选择的物品8的所有同类物品8的信息显示于所述显示屏5上。本实施例中，对于图像中的物品8，可通过图像识别算法，自动勾勒出物品8的轮廓，这一过程类似智能手机拍照时的人脸识别过程，即相机甄别到人脸时，即自动产生一个方框，对人脸进行追踪；同样的，本实施例中，所述摄像头2采集到物品8的图像后，控制单元4根据图像识别算法自动勾勒出物品8的轮廓，用户可便捷地点击(或框选等，下同)对应物品8的轮廓区域，即可选择物品8； 或者，用户点击其中一件物品8，算法即自动识别用户点击的物品8，并自动选择图像中用户点击的物品8的所有同类物品8，更加智能化。
请再次参照图2所示，所述控制单元4经由一触发按键3和/或按钮7的触发，来控制控制所述摄像头2采集图像，以及所述定向天线模块1发射或接收信号。
一种实施例中(未图示，下同)，用户可在所述显示屏5上手动操作，以框选一个区域内物品8的图像，其对应待读取区域P内相应区域的物品8，进而，所述控制单元4根据用户选择的物品8的范围来调整所述定向天线模块1的接收范围A(A’)，使二者相匹配，使得所述定向天线模块1仅读取用户选择的物品8，或使得所述定向天线模块1仅读取所述显示屏5上用户选择的物品8之外的其它物品8。之后，所述显示屏5进一步显示用户选择的物品8的信息，或显示排除掉用户选择的物品8后其它物品8的信息。
另一种实施例中(未图示，下同)，所述显示屏5用以供用户操作，以分别选择图像中的第一区域和第二区域，所述射频识别终端100进一步根据预设读取第一区域和第二区域的交集区域或并集区域或余集区域的物品8信息。其中，交集区域即指所述所述第一区域与所述第二区域相交(重叠)的区域，并集区域即指所述所述第一区域与所述第二区域合并在一起的区域，余集区域即指第一区域中除去第二区域后的区域或第二区域中除去第一区域后的区域。具体读取交集区域或并集区域或余集区域中的哪一区域，均可通过需要来预设。当然，也可通过预设来读取交集区域、并集区域和余集区域之外的其它区域。所述控制单元4进一步调整所述定向天线模块1的接收范围A(A’)，以读取对应区域中的物品8信息。之后，所述显示屏5显示读取的物品8的信息。
在又一种实施例中(未图示，下同)，所述定向天线模块1预先读取了所述显示屏5上显示的所有物品8的信息，当用户通过前几种实施例中的方式选定了目标物品8后，所述控制单元4即根据用户选择的目标物品8筛选出所述定向天线模块1接收到的对应的物品8的信息，并进一步显示于所述显示屏5上。或者，所述定向天线模块1预先读取了所述显示屏5上显示的所有物品8的信息，所述控制单元4进一步将所有物品8的信息分类显示于所述显示屏5上，供用户选择，当用户点选某一类或几类物品8之后， 所述控制单元4进一步将用户选择的物品8的信息显示于所述显示屏5上。
在其它实施例中(未图示，下同)，用户无需手动选择目标物品8，即当所述摄像头2采集到待读取区域P的图像之后，所述射频识别终端100自动甄别图像中可识别的物品8，而剔除不可识别的物品8，并进一步筛选出可识别物品8的信息。本实施例的射频识别终端100适用于清点种类繁多的物品8中，某一类或某几类特定的物品8，而剔除掉其它物品8。由于无需用户在显示屏5上操作来选择物品8，更加快捷；甚至所述射频识别终端100可以不设置显示屏5，而将识别的物品8的信息传输至上位机(未图示，下同)来显示。
如图7所示，为本发明一种实施例的射频识别终端100的使用方法的流程图，包括以下步骤：
S1：通过摄像头2采集待读取区域P的图像，并通过显示屏5显示待读取区域P的图像。
所述显示屏5上设有一个显示区域51，所述显示区域51通过线条在所述显示屏5上示出，从而形成一个显示框，所述摄像头2采集的待读取区域P的图像显示于所述显示屏5上，且所述显示区域51的形状经人为设定，使得所述显示区域51显示的范围与定向天线模块1的接收范围A(A’)大致重合。
S2：通过定向天线模块1接收待读取区域P中的电子标签81发射的信号。
S3：在所述显示屏5上手动选择图像中的物品8。

其它手动选择物品8的方法，也可参照前述其它实施例中用户选择物品8的方法。
S4：筛选出选择的物品8的信息。
筛选出选择的物品8的信息可包括：控制单元4首先通过深度学习神经网络将用户选择的物品8的图像与存储单元6中的图像库进行比对，以识别用户选择的物品8。具体来说，所述射频识别终端100可通过深度学习神经网络建立多种待识别物品8的图像库，并将图像库存储于存储单元6中以供所述控制单元4调用。
之后，所述控制单元4根据不同物品8上的电子标签81的信息的区别特征，在所述定向天线模块1接收到的所有电子标签81的信息中，筛选出用户选择的物品8的所有同类物品8的信息。
在S4之后，所述控制单元4进一步将用户选择的物品8的信息显示于所述显示屏5上。

S20:通过定向天线模块1接收待读取区域P中的电子标签81发射的信号。
S30:通过控制单元4经由深度学习神经网络，将所述摄像头2采集的图像与存储单元6中的图像库进行比对，以识别目标物品8，并进一步筛选出所述定向天线模块1接收的信号中目标物品8的信息。

如图8所示，为本发明射频识别终端100的使用方法的流程图，包括以下步骤：
S100：通过摄像头2采集待读取区域P的图像，并通过显示屏5显示待读取区域P的图像。
所述显示区域51显示的范围与所述定向天线模块1的接收范围A(A’)大致重合。

在所述显示屏5上手动选择图像中的物品8包括：分别选择图像中的第一区域和第二区域，且根据预设读取第一区域和第二区域的交集区域或并集区域或余集区域的物品8信息；详细操作方法可参照前述实施例中的描述。其它手动选择物品8的方法，也可参照前述其它实施例中用户选择物品8的方法。
S300：调整定向天线模块1的接收范围A(A’)至选择的物品8所在的范围，并接收选择的物品8上的电子标签81发射的信号。
在S300之后，所述控制单元4处理接收到的电子标签81的信息并进一步显示于所述显示屏5上。
