在该实施例中，目标对象为需要进行定位的对象，比如，该目标对象为车辆。预设区域与目标对象具有对应关系，可以为目标对象停靠的区域，比如，为停车库中的停车位。通过信息采集装置102获取目标对象的第一标签信息及预设区域的第二标签信息，该第一标签信息包括第一标签码和第一信号强度，该第二标签信息包括第二标签码和第二信号强度，其中，第一标签码和第二标签码可以为无线射频识别中的身份标识号(ID)，分别具有对应的第一信号强度和第二信号强度，第一信号强度和第二信号强度可以为无线射频识别信号的强度。
在信息采集装置102获取目标对象的第一标签信息及预设区域的第二标签信息之后，可以判断第一信号强度和第二信号强度是否满足预设条件，该预设条件为用于触发根据预设区域的第二标签码获取预设区域的位置信息的条件。比如，判断第一信号强度 和第二信号强度是否相近，可以判断第一信号强度和第二信号强度之间的差值是否小于预设阈值。如果判断出第一信号强度和第二信号强度之间的差值小于预设阈值，确定第一信号强度和第二信号强度满足预设条件，可以根据预设区域的第二标签码获取预设区域的位置信息。该预设区域的位置信息用于指示预设区域的位置，可以为预设区域的坐标，该第二标签码和预设区域的位置信息也具有一一对应的关系。
控制器104，与信息采集装置102相连接，用于根据预设区域的位置信息，确定目标对象的位置。
该实施例的控制器104可以为控制台，可以是个人计算机(Personal Computer，PC)机上的一套控制软件，用于展示目标对象的位置状况，比如，用于展示车辆的位置状。该实施例可以通过分析预设区域上的第二标签信息和目标对象上的第一标签信息来实现预设区域与目标对象之间的对应关系。可选地，该控制器104与信息采集装置102相连接，用于获取信息采集装置102上传的预设区域的位置信息和第一标签码，可以根据预设区域的位置信息及第一标签码，确定目标对象的位置，比如，根据第一标签码，将预设区域的位置信息所指示的位置确定为目标对象的位置，从而实现了对目标对象的定位。
该实施例的定位系统通过预设区域上的标签信息实现预设区域的位置信息的导入，实现了使用标签信息同步目标对象和预设的位置信息，方便实用，从而实现了提高对目标对象进行定位的效率的技术效果，进而解决了由于定位复杂造成的对目标对象进行定位的效率低的技术问题。
可选地，信息采集装置102包括：接收模块，用于接收第一信息采集装置发送的第一标签信息及第二标签信息，其中，第一信息采集装置从设置在目标对象上的第一标签采集第一标签信息，以及从设置在预设区域内的第二标签采集第二标签信息。
在该实施例中，第一信息采集装置可以为RFID读写器，可以为手持式的RFI读写器，通讯距离大概10-20米，可以通过调节功率天线等控制在0.1-20米的范围，用于采集周边RFID标签的位置。在该实施例中，第一信息采集装置可以采集目标对象的第一标签信息和预设区域的第二标签信息，并将第一标签信息和第二标签信息向信息采集装置102的接收模块发送，可以通过通用串行总线(Universal Serial Bus，简称为USB)等通讯方式向接收模块发送，该接收模块用于接收第一标签信息和第二标签信息，进而通过USB等通讯方式导入到控制器104上。
该实施例的目标对象上设置有第一标签，该第一标签可以贴在目标对象上，可以为RFID标签，也即，电子标签，可以通过无线电讯号识别特定目标并读写相关数据，而无 需识别系统与特定目标之间建立机械或者光学接触。该实施例的预设区域内设置有第二标签，该第二标签可以为RFID标签，比如，预设区域为停车位，每个停车位上布置一个RFID标签。由于RFID标签只需要贴在相应位置就可以了，从而不需要电源，不需要布线，简单且实用。
该实施例的第一信息采集装置可以从第一标签采集第一标签信息，比如，从设置在目标对象上的RFID标签采集ID信息，从设置在预设区域内的第二标签采集第二标签信息，可以从设置在预设区域上的RFID标签采集ID信息，该ID信息可以反映出预设区域的具体位置。
可选地，第一信号强度与第二信号强度满足预设条件包括：计算第一信号强度与第二信号强度的差值；若差值小于等于预设阈值，第一信号强度与第二信号强度满足预设条件；若差值大于预设阈值，第一信号强度与第二信号强度不满足预设条件。
该实施例的目标对象的第一标签信息包括第一标签码和第一信号强度，预设区域的第二标签信息包括第二标签码和第二信号强度，在确认第一信号强度和第二信号强度是否满足预设条件时，可以获取第一信号强度和第二信号强度之间的差值，比如，计算第一信号强度和第二信号强度的差值，判断差值是否小于预设阈值，该预设阈值为用于确定第一信号强度和第二信号强度是否满足预设条件的临界值。在第一信号强度与第二信号强度之间的差值小于等于预设阈值的情况下，则可以确定第一信号强度与第二信号强度满足预设条件，当预设阈值很小的情况下，可以认为第一信号强度和第二信号强度相近，进而根据第二标签码获取预设区域的位置信息，根据预设区域的位置信息，确定目标对象的位置；在第一信号强度与第二信号强度之间的差值大于预设阈值的情况下，则可以确定第一信号强度与第二信号强度不满足预设条件，则此时不能根据第二标签码获取预设区域的位置信息。
可选地，信息采集装置102包括：读取模块，用于从预先存储的对应关系库中，读取第二标签码对应的预设区域的位置信息，其中，第二标签码与预设区域为一一对应的关系，预设区域的位置信息包括预设区域的坐标。
在该实施例中，对应关系库用于预先存储预设区域的第二标签码与预设区域的位置信息之间的对应关系，该第二标签码与预设区域之间具有一一对应的关系，从而使得第二标签码与预设区域的位置信息之间具有一一对应的关系。可选地，当预设区域为停车位时，对应关系库用于预先存储停车位上的标签信息中的第二标签码和停车位的位置信息之间的对应关系。这样该实施例的信息采集装置102中的读取模块可以从预先存储的 对应关系库中，读取第二标签码对应的预设区域的位置信息，该预设区域的位置信息包括预设区域的坐标，可以通过预设区域的坐标来指示预设区域的位置，进而根据预设区域的位置信息，确定目标对象的位置。
可选地，定位系统中的控制器104根据预设区域的位置信息，确定目标对象的位置包括：根据第一标签码，确定第一标签的位置为预设区域的坐标，其中，第一标签设置在目标对象上，第一标签与目标对象为一一对应的关系；基于第一标签的位置，将目标对象的位置确定为预设区域的坐标。
在该实施例中，目标对象上设置有第一标签，该第一标签可以用于唯一标识目标对象。定位系统在根据预设区域的位置信息，确定目标对象的位置时，可以根据第一标签信息中的第一标签码，将预设区域的位置信息确定为第一标签的位置信息，可以将预设区域的坐标确定为第一标签的位置，比如，根据设置在目标对象设置的RFID标签中的ID，将预设区域的坐标确定为目标对象设置的RFID标签的位置。由于第一标签与目标对象具有一一对应的关系，在将预设区域的坐标确定为第一标签的位置之后，基于第一标签的位置信息，将目标对象的位置信息确定为预设区域的位置信息，可以基于第一标签的位置，将目标对象的位置确定为预设区域的坐标，从而实现了根据预设区域的位置信息，确定目标对象的位置的目的，实现了对目标对象进行定位，提高了对目标对象进行定位的效率。
可选地，在目标对象出库时，接收第二信息采集装置发送的目标对象的第一标签码；从预先接收到的出库记录中，查找是否包含有第一标签码，出库记录用于指示允许出库的对象；若包含，则删除第一标签码与目标对象的对应关系；若不包含，则输出报警信息，报警信息用于指示不允许目标对象出库。
在该实施例中，目标对象具有入库和出库的过程，比如，目标对象为车辆。该实施例的定位系统在目标对象入库时，会在目标对象上贴一个第一标签，并且记录该第一标签与目标对象的对应关系，比如，在车辆入库时会在车上贴一个RFID标签，并且记录该RFID标签与车辆的ID号码(车架号或者发动机号等)之间的对应关系。
该实施例的定位系统在目标对象出库时，接收第二信息采集装置发送的目标对象的第一标签信息中的第一标签码，该第二信息采集装置可以为RFID读写器，比如，为停车库的出口处设置的RFID读写器，可以用于发送目标对象的第一标签信息中的ID。目标对象在出库时在定位系统中具有出库记录，出库记录用于指示允许出库的对象，可以包括允许出库的对象的标签信息中的标签码。该实施例的定位系统预先接收出库记录， 这样在接收第二信息采集装置发送的目标对象的第一标签码之后，从预先接收到的出库记录中，查找出库记录中是否包含有第一标签码。在查找出库记录中是否包含有第一标签码之后，如果查找到出库记录中包含有第一标签码，则允许目标对象出库，同时删除第一标签码与目标对象的对应关系，如果查找到出库记录中不包含有第一标签码，也即，第一标签码未在定位系统中有记录，则输出报警信息，报警信息用于指示不允许目标对象出库，从而提醒相关人员采取措施以不允许目标对象出库。
该实施例的定位系统通过信息采集装置102获取目标对象的第一标签信息及预设区域的第二标签信息，其中，第一标签信息包括第一标签码和第一信号强度，第二标签信息包括第二标签码和第二信号强度；在第一信号强度与第二信号强度满足预设条件的情况下，根据第二标签码获取预设区域的位置信息，通过控制器104根据预设区域的位置信息，确定目标对象的位置，达到了对目标对象进行定位的目的，适用于室内定位。并且通过上述定位系统避免了直接使用GPS，或者使用率高北斗定位芯片进行定位，而不适合室内定位的局限性，避免了在目标对象上安装有蓝牙或WIFI的接收器，而需要室内布置信标系统，比较复杂的问题，避免了目标对象还需要放置蓝牙接收器实现低功耗困难的问题，避免了通过布置地磁传感器的方式来检测目标对象，所导致的成本高昂，改造复杂等问题，避免了通过在车库内布置摄像头的方式进行视频识别，识别困难的问题，从而实现了提高对目标对象进行定位的效率的技术效果，进而解决了由于定位复杂造成的对目标对象进行定位的效率低的技术问题。
下面结合优选的实施例对本发明的技术方案进行举例说明。具体以目标对象为车辆，预设区域为停车库的停车位进行举例说明。
很多进口车在保税区会停放在停车库，该停车库可能是室内的，也可能是露天的；车库口有门禁装置会检测到该车辆有没有被允许出库；车辆在车库中可能会有移动；一般车辆在停车库内可能停放半年到一年以上的时间。
图2A是根据本发明实施例的一种停车库的示意图。如图2A所示，停车库的停车位通过数字编号进行标识，一个数字编号用于代表一个停止位，数字编号的数量也即停车位的数量，车辆停放在与数字编号对应的停车位上。
可选地，本发明实施例的定位系统可以应用在图2A所示的停车库中。
图2B是根据本发明实施例的另一种定位系统的示意图。如图2B所示，该实施例的定位系统包括RFID位置标签1、RFID车辆标签2、手持式RFID读写器3、控制台4和闸机RFID读写器5。该实施例在每个停车位上布置一个RFID位置标签1，该RFID位 置标签1的ID可以反映出停车位的具体位置。
在车辆入库时，会在车辆上贴一个RFID车辆标签2，并且记录该RFID车辆标签2与车辆的ID号码(车架号或者发动机号等)之间的对应关系。车辆停放在车库的某一个停车位上。
在停车库中，通过一个手持式RFID读写器3可以读取周边设置的RFID标签的位置，该手持式RFID读写器3采集到停车位上的标签信息和车上的标签信息可以通过USB等通讯方式导入到控制台4上，该控制台4可以是PC机上的一套控制软件，可以用于展示每台车辆的位置状况。
可选地，每隔一段时间车库管理员会拿着手持式RFID读写器3在车库内走一圈(也可以采用助动车等手段)，比如，1天，每隔一天，车库管理员会拿着手持式RFID读写器3在车库内走一圈，通过手持式RFID读写器3采集到停车位上的标签信息和车上的标签信息，并通过USB等通讯方式传到控制台4上。可以在控制台4中分析停车位上的标签信息和车上的标签信息来实现车位与车辆的对应关系。
需要补充说明书的是，本实施例包括但不限于由车库管理员手持RFID读写器的方式进行标签信息采集，也可以通过自动寻路的机器人或者无人机等设备巡视车库以实现标签信息的采集，均应在本实施例的保护范围内。
该实施例的车辆的标签信息包括第一标签码和第一信号强度，停车位的标签信息包括第二标签码和第二信号强度，可以计算第一信号强度和第二信号强度的差值，判断差值是否小于预设阈值。在第一信号强度与第二信号强度之间的差值小于等于预设阈值的情况下，则可以确定第一信号强度与第二信号强度满足预设条件，当预设阈值很小的情况下，可以认为第一信号强度和第二信号强度相近，进而根据停车位的第二标签码获取停车位的位置信息，根据停车位的位置信息和第一标签码确定车辆的位置；在第一信号强度与第二信号强度之间的差值大于预设阈值的情况下，则可以确定第一信号强度与第二信号强度不满足预设条件，则此时不能根据第二标签码获取预设区域的位置信息。
当车辆出库时，应当在控制系统中记录出允许出库的对象的标签码。该实施例在停车库的出口处(闸机)放置一个闸机RFID读写器5，如果通过闸机RFID读写器5检测出库记录中不包含有待驶出车库的车辆的标签码，则需要报警提示，从而提醒相关人员采取措施以不允许目标对象出库。
该实施例采用的一个RFID标签大约0.5元人民币，RFID读写器的通讯距离大概10至20米，可以通过调节功率天线等控制在0.1至20米的范围。采用在停车位上贴RFID 标签的方式来实现车库位置信息的导入，实现了使用RFID标签同步车辆和车位的位置信息，方便实用。超高频RFID标签当前价格在0.3至0.5元人民币左右，价格便宜，降低了定位系统的成本，车库改造成本低；并且易布置，RFID标签只需要贴在相应位置就可以了，不需要电源，不需要布线；简单且使用。对于定位系统在停车库的场景下，精度大约1至5米，对于停车库的定位已经足够。
需要说明的是，该实施例中以超高频RFID电子标签技术为例进行了说明，在某些场合也可以采用低功耗蓝牙(BLE)Beacon的方案以达到同样的效果，只是蓝牙上需要一个电池，成本比较高，20元左右，本实施例的定位方法还可以采用高频RFID电子标签技术进行定位，均应在本实施例的保护范围之内。

作为一种可选的实施方式，步骤S402，获取目标对象的第一标签信息及预设区域的第二标签信息包括：接收第一信息采集装置发送的第一标签信息及第二标签信息，其中，第一信息采集装置从设置在目标对象上的第一标签采集第一标签信息，以及从设置在预设区域内的第二标签采集第二标签信息。

作为一种可选的实施方式，步骤S406，根据预设区域的位置信息，确定目标对象的位置包括：根据第一标签码，确定第一标签的位置为预设区域的坐标，其中，第一标签设置在目标对象上，第一标签与目标对象为一一对应的关系；基于第一标签的位置，将目标对象的位置确定为预设区域的坐标。
在该实施例中，目标对象上设置有第一标签，该第一标签可以用于唯一标识目标对象。在根据预设区域的位置信息，确定目标对象的位置时，可以根据第一标签信息中的第一标签码，将预设区域的位置信息确定为第一标签的位置信息，可以将预设区域的坐标确定为第一标签的位置，比如，根据设置在目标对象设置的RFID标签中的ID，将预设区域的坐标确定为目标对象设置的RFID标签的位置。由于第一标签与目标对象具有 一一对应的关系，在将预设区域的坐标确定为第一标签的位置之后，基于第一标签的位置信息，将目标对象的位置信息确定为预设区域的位置信息，可以基于第一标签的位置，将目标对象的位置确定为预设区域的坐标，从而实现了根据预设区域的位置信息，确定目标对象的位置的目的，实现了对目标对象进行定位，提高了对目标对象进行定位的效率。
作为一种可选的实施方式，在目标对象出库时，接收第二信息采集装置发送的目标对象的第一标签码；从预先接收到的出库记录中，查找是否包含有第一标签码，出库记录用于指示允许出库的对象；若包含，则删除第一标签码与目标对象的对应关系；若不包含，则输出报警信息，报警信息用于指示不允许目标对象出库。
在该实施例中，目标对象具有入库和出库的过程，比如，目标对象为车辆。在目标对象入库时，会在目标对象上贴一个第一标签，并且记录该第一标签与目标对象的对应关系，比如，在车辆入库时会在车上贴一个RFID标签，并且记录该RFID标签与车辆的ID号码(车架号或者发动机号等)之间的对应关系。
在目标对象出库时，接收第二信息采集装置发送的目标对象的第一标签信息中的第一标签码，该第二信息采集装置可以为RFID读写器，比如，为停车库的出口处设置的RFID读写器，可以用于发送目标对象的第一标签信息中的ID。目标对象在出库时具有出库记录，出库记录用于指示允许出库的对象，可以包括允许出库的对象的标签信息中的标签码。该实施例的定位系统预先接收出库记录，这样在接收第二信息采集装置发送的目标对象的第一标签码之后，从预先接收到的出库记录中，查找出库记录中是否包含有第一标签码。在查找出库记录中是否包含有第一标签码之后，如果查找到出库记录中包含有第一标签码，则允许目标对象出库，同时删除第一标签码与目标对象的对应关系，如果查找到出库记录中不包含有第一标签码，也即，第一标签码未在定位系统中有记录，则输出报警信息，报警信息用于指示不允许目标对象出库，从而提醒相关人员采取措施以不允许目标对象出库。
该实施例的定位方法通过获取目标对象的第一标签信息及预设区域的第二标签信息，其中，第一标签信息包括第一标签码和第一信号强度，第二标签信息包括第二标签码和第二信号强度；在第一信号强度与第二信号强度满足预设条件的情况下，根据第二标签码获取预设区域的位置信息，通过根据预设区域的位置信息，确定目标对象的位置，达到了对目标对象进行定位的目的，并且通过上述定位系统避免了直接使用GPS，或者使用率高北斗定位芯片进行定位，而不适合室内定位的局限性，避免了在目标对象上安 装有蓝牙或WIFI的接收器，而需要室内布置信标系统，比较复杂的问题，避免了目标对象还需要放置蓝牙接收器实现低功耗困难的问题，避免了通过布置地磁传感器的方式来检测目标对象，所导致的成本高昂，改造复杂等问题，避免了通过在车库内布置摄像头的方式进行视频识别，识别困难的问题，从而实现了提高对目标对象进行定位的效率的技术效果，进而解决了由于定位复杂造成的对目标对象进行定位的效率低的技术问题。
需要说明的是，对于前述的各方法实施例，为了简单描述，故将其都表述为一系列的动作组合，但是本领域技术人员应该知悉，本发明并不受所描述的动作顺序的限制，因为依据本发明，某些步骤可以采用其他顺序或者同时进行。其次，本领域技术人员也应该知悉，说明书中所描述的实施例均属于优选实施例，所涉及的动作和模块并不一定是本发明所必须的。
