Description

一种定位方法和装置
本申请要求于2021年04月28日提交国家知识产权局、申请号为202110466932.5、申请名称为“一种定位方法和装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请实施例涉及电子设备领域，尤其涉及一种定位方法和装置。
背景技术
在很多电子设备的使用场景下，都需要对电子设备进行定位。示例性的，电子设备通过对自身进行定位，能够提供导航、寻物等功能。
目前，常用的电子设备定位方法可以包括通过全球定位系统(Global Positioning System,GPS)进行定位。示例性的，在进行定位时，电子设备可以进行搜星，即搜索能够与电子设备进行通信的定位卫星。在搜索到至少3个定位卫星后，电子设备可以与定位卫星进行通信，获取至少3个定位卫星与电子设备的相对位置信息，由此确定电子设备的位置信息。比如电子设备的位置信息可以为经纬度等。可以理解的是，电子设备搜星时搜索到的定位卫星的数量越大，则可以获取更多数量的定位卫星与电子设备的相对位置信息，由此即可获取更加准确的电子设备的位置信息。
然而，在一些场景下，电子设备无法进行准确的GPS定位。示例性的，在一些场景下，当电子设备搜星时，无法搜索到3个或更多定位卫星，那么就无法获取足够数量的定位卫星之间的相对位置信息，也就无法据此确定电子设备的位置信息。在另一些场景下，当电子设备处于复杂环境中(如周边环境密集的城市环境中，又如室内环境中)时，则会由于获取的定位卫星与电子设备的相对位置信息不准确，导致获取的定位信息准确度下降甚至无法进行定位。
发明内容
本申请实施例提供一种定位方法和装置，能够对待定位设备进行准确的定位，避免由于周边环境较为复杂导致的定位不准确或者无法定位的问题。同时也不要求电子设备具备定位能力，因此能够适用于各种电子设备的定位场景中。另外，由于在不同的定位场景中，不存在多种定位策略的切换，也就避免了碎片化的定位方案导致的定位受阻。
为了达到上述目的，本申请实施例采用如下技术方案：
第一方面，提供一种定位方法，该方法用于对待定位设备进行定位。该方法包括：在对该待定位设备进行定位时，确定待定位设备的一个或多个关联设备。其中，在该待定位设备执行应用时，该关联设备与该待定位设备发生应用关联关系。该应用关联关系包括：该关联设备在该待定位设备执行应用时，因直接或间接地配合该待定位设备实现该应用的功能，而与该待定位设备发生的关联关系。获取一个或多个该关联设备的定位参考信息。根据该一个或多个该关联设备的定位参考信息，确定该待定位设备的位置信息。
基于该方案，提供了一种对待定位设备进行定位的方法示例。在该示例中，可以根据待定位设备的关联设备实现对待定位设备的定位。其中，关联设备可以是与待定位设备具有应用层关联的设备。可以理解的是，以待定位设备为手机为例，手机可以通过与其他的设备进行交互，实现各种功能。比如，手机可以通过与POS机的交互，实现支付功能。又如，手机可以通过扫描二维码，由此获取二维码对应的信息。由此，在待定位设备不同的应用场景下，一般都会存在至少一个待定位设备的关联设备。需要说明的是，在本示例中，关联设备可以包括能够直接与待定位设备进行交互由此提供对应服务的设备。关联设备还可以包括间接配合待定位设备实现相应的功能。例如，与直接配合该待定位设备实现具体功能的关联设备发生关联关系，以达成间接地配合实现该具体功能的设备。在对待定位设备进行定位的过程中，可以根据手机对应的关联设备的定位参考信息，实现对待定位设备的定位。由于关联设备可以具有定位功能，也就是说，关联设备的位置可以是直接或间接确定的，而关联设备由于是当前场景下与待定位设备具有应用关联关系的设备，则待定位设备通常会在关联设备所在位置的一定范围内，因此能够根据关联设备的定位参考信息对待定位设备进行准确地定位。同时，由于关联设备的定位参考信息不受当前场景的变化的影响，因此不会出现类似与GPS定位过程中，由于场景中物体的干扰导致的定位不准确的问题。另外，本方案也不需区分不同的定位场景，因此能够适用于大多数的定位场景中。
在一种可能的设计中，与该待定位设备具有应用关联关系的关联设备包括第一关联设备。该获取一个或多个该关联设备的定位参考信息，包括：获取该第一关联设备的第一定位参考信息。该根据该一个或多个该关联设备的定位参考信息，确定该待定位设备的位置信息，包括：确定该待定位设备的位置在该第一定位参考信息所指示的位置的一定范围内。基于该方案，提供了一种具体的对待定位设备进行定位的方案示例。在本示例中，以关联设备至少包括1个设备(如第一关联设备)为例。那么，可以通过该第一关联设备的位置，确定待定位设备位于第一关联设备的附近。比如，以室内定位场景为例。GPS定位需要获取待定位设备与至少3个定位卫星之间的精确距离。但是由于待定位设备位于室内环境，因此无法对上述距离进行精确测量，其误差往往大于1km，甚至无法测量。而基于本方案，由于第一关联设备位于待定位设备附近，只要能够确定第一关联设备的位置即可对待定位设备进行定位。比如，以第一关联设备为POS机为例，为了能够与POS机进行交互，实现支付功能，待定位设备与POS机的距离不会超过POS机的工作距离(如小于5cm)。由此根据本申请提供的方案，能够提升待定位设备的定位准确度。
在一种可能的设计中，该第一定位参考信息包括第一位置信息。确定该待定位设备的位置在该第一定位参考信息所指示的位置的一定范围内，包括：确定该待定位设备的位置为该第一位置信息指示的位置。基于该方案，提供了一种具体的根据关联设备对待定位设备进行定位的方案示例。在该示例中，第一定位参考信息中，具体可以包括第一关联设备的位置(如第一位置信息指示的位置)。结合前述方案中的说明，由于第一关联设备与待定位设备的位置上的关联性，因此根据第一关联设备的位置就可以实现对待定位设备的准确定位。
在一种可能的设计中，该第一定位参考信息还包括：第一定位精度。确定该待定 位设备的位置在该第一定位参考信息所指示的位置的一定范围内，包括：确定该待定位设备的位置在该第一位置信息指示的位置的第一精度范围内，其中，该第一精度范围由该第一定位精度指示。基于该方案，提供了又一种具体的根据关联设备对待定位设备进行定位的方案示例。在该示例中，在根据关联设备的位置，对待定位设备进行定位的基础上，还可以参考关联设备的定位精度，进一步明确待定位设备的位置。作为确定设备定位精度的一种可能方式，不同的设备均具有对应的有效覆盖区域，在该有效覆盖区域内，就可以与待定位设备进行应用关联，实现向待定位设提供服务的效果，因而可以将该有效覆盖区域作为设备的定位精度。或者，也可以根据需要设置其他参数指标作为定位精度。也就是说，根据该定位精度，可以圈定待定位设备的位置范围。因此，根据第一位置信息以及第一定位精度能够对待定位设备进行更加准确地定位。
在一种可能的设计中，在该获取该第一关联设备的第一定位参考信息之前，该方法还包括：确定该第一关联设备是否具有定位能力。该获取该第一关联设备的第一定位参考信息，包括：在该第一关联设备具有定位能力的情况下，获取该第一定位参考信息。基于该方案，提供了一种根据第一关联设备对待定位设备进行定位的触发机制。在通过第一关联设备对待定位设备进行定位的情况下，需要能够知晓第一关联设备的位置信息。也就是说，需要第一关联设备具有定位能力。通过本方案，能够在获取第一关联设备的定位参考信息之前，确定第一关联设备具有定位能力，由此避免由于第一关联设备不具备定位能力而导致的定位参考信息获取失败的情况发生。
在一种可能的设计中，与该待定位设备具有应用关联关系的关联设备包括第二关联设备，该第二关联设备为直接配合该待定位设备实现该应用的功能的设备，在该第二关联设备不具有定位能力的情况下，该方法还包括：获取第三关联设备的第二定位参考信息，该第三关联设备是该第二关联设备的关联设备。该根据该一个或多个该关联设备的定位参考信息，确定该待定位设备的位置信息，包括：根据该第二定位参考信息确定该待定位设备的位置。基于该方案，提供了一种待定位设备的关联设备不具备定位能力的情况下，对待定位设备进行定位的方案示例。在本示例中，可以通过与第二关联设备具有应用关联关系的第三关联设备，对待定位设备进行定位。可以理解的是，与通过第二关联设备对待定位设备进行定位的思路类似，在第二关联设备不具备定位能力的情况下，可以通过第三关联设备确定第二关联设备的位置。比如，根据第三关联设备的定位参考信息对确定第二关联设备的位置。进而据此确定待定位设备的位置。可见，通过本方案，即使作为待定位设备的关联设备的第二关联设备不具备定位能力，也可以通过第三关联设备对待定位设备进行定位。在本示例及以下相关示例的说明中，第二关联设备由于可以直接与待定位设备进行应用关联，因此可以称为1级关联设备。对应的，第三关联设备可以称为待定位设备的2级关联设备。
在一种可能的设计中，该获取一个或多个该关联设备的定位参考信息，包括：获取该第二关联设备的第二定位精度。根据该定位参考信息，确定该待定位设备的位置信息，包括：根据该第二定位参考信息，和该第二定位精度，确定该待定位设备的位置。基于该方案，提供了一种具体的根据1级关联设备以及2级关联设备对待定位设备进行定位的方案示例。在本示例中，可以根据2级关联设备的定位参考信息，确定 1级关联设备的位置，进而根据确定的1级关联设备的位置以及1级关联设备的定位精度，对待定位设备进行定位。
在一种可能的设计中，该第二定位参考信息包括：第二位置信息和第三定位精度。该待定位设备的位置包括：在该第二位置信息指示的位置的第二精度范围内，其中，该第二精度范围由该第二定位精度和该第三定位精度共同指示。基于该方案，提供了一种具体的对待定位设备进行定位的方案示例。在该示例中，明确了根据2级关联设备以及1级关联设备对待定位设备进行定位的情况下，待定位设备的位置为：2级关联设备所在位置附近一定范围内。该一定范围可以是2级关联设备的定位精度以及1级关联设备的定位精度所覆盖区域之和。可以理解的是，2级关联设备的定位精度以及2级关联设备位置，可以指示1级关联设备的位置。在此基础上再参考1级关联设备的定位精度，即可对待定位设备进行准确地定位。
在一种可能的设计中，该待定位设备在当前场景下的关联设备还包括第四关联设备。该第四关联设备具有定位能力。该方法还包括：获取该第四关联设备的第三定位参考信息。该根据该一个或多个该关联设备的定位参考信息，确定该待定位设备的位置信息，包括：根据该第一定位参考信息和该第三定位参考信息，确定该待定位设备的位置信息。基于该方案，提供了又一种根据多个关联设备进行定位的方案示例。结合本示例的方案，在一些场景下，待定位设备对应的关联设备可以为多个。这样，根据本示例的方案，可以结合多个关联设备的定位参考信息，对待定位设备进行定位。可以理解的是，通过多个关联设备对待定位设备进行定位的情况下，能够进一步缩小待定位设备可能的位置区域，因此能够进一步提升待定位设备的定位准确度。
在一种可能的设计中，该第一定位参考信息包括第一位置信息和第一定位精度，该第三定位参考信息包括第三位置信息和第四定位精度。该待定位设备的位置信息包括：该待定位设备位于定位区域内，该定位区域包括第一区域和第二区域的重叠部分，该第一区域为该第一位置信息指示的位置的第一精度范围内的区域，该第一精度范围由该第一定位精度指示。该第二区域为该第三位置信息指示的位置的第三精度范围内的区域，该第三精度范围由该第四定位精度指示。基于该方案，提供了一种基于多个关联设备进行定位的具体方案示例。在本示例中，根据第一关联设备可以圈定一个待定位设备所在位置的范围(如称为范围1)。类似的，根据第二关联设备的定位参考信息，也可以确定一个待定位设备所在位置的范围(如称为范围2)。由于待定位设备在当前场景下可以同时与两个关联设备建立应用关联关系，因此待定位设备的实际位置可以位于范围1和范围2的重叠区域中。由此相较于单独根据第一关联设备或者第二关联设备对待定位设备进行定位的方案，能够有效地缩小待定位设备所在区域的范围，因此能够提升准确度。
在一种可能的设计中，该确定待定位设备的一个或多个关联设备，包括：接收定位请求，该定位请求包括该待定位设备的设备标识。根据该设备标识，确定一个或多个该关联设备。或者，接收定位请求，该定位请求中包括该待定位设备的一个或多个该关联设备标识。根据关联设备标识，确定该关联设备。基于该方案，提供了一种关联设备的确定方案。在本示例中，待定位设备可以向执行本方案的设备(比如设备云等)发送定位请求，以便于设备云明确待定位设备具有定位的需求。设备云可以根据 定位请求中携带的信息，确定待定位设备的关联设备。可以理解的是，设备云可以用于对包括待定位设备在内的一系列设备的设备管理。这样，设备云就能够知晓在不同场景下，各个设备之间所产生的应用关联关系。在本示例的一些实现中，设备云可以根据定位请求中的待定位设备的标识，确定当前需要定位的设备。进而根据对各个设备的管理情况，确定当前该待定位设备对应的关联设备。需要说明的是，在一些实现中，该定位请求中也可以不携带待定位设备的标识，设备云依然可以根据接收到定位请求的接口或者传输资源确定发送定位请求的设备。不同与上述场景的示例，在一些实现中，待定位设备还可以根据当前所处场景中与其他设备的交互情况，自主确定关联设备。待定位设备可以在定位请求中，将确定的关联设备(或者关联设备的标识)发送给设备云，以便于设备云可以确定待定位设备以及关联设备。
在一种可能的设计中，在根据接收的该定位请求无法确定该待定位设备的关联设备的情况下，该方法还包括：确定该待定位设备的一个或多个历史关联设备，该历史关联设备是根据历史已发生的该待定位设备和关联设备之间的应用关联关系确定的关联设备。获取该一个或多个历史关联设备的历史定位参考信息，根据该历史定位参考信息，确定该待定位设备的位置信息。基于该方案，提供了又一种对待定位设备进行定位的方案实现。可以理解的是，如果待定位设备在需要进行定位时，如果存在关联设备，那么就可以按照上述示例中的方案对待定位设备进行定位。而在一些场景下，在待定位设备需要进行定位时，可能并未与其他设备具有应用关联关系。或者，在待定位设备需要进行定位时，无法确定当前场景下的关联设备。那么，基于本示例中的方案，可以通过待定位设备在需要进行定位之前，与其他具有应用关联关系的设备(如历史关联设备)，对当前待定位设备的位置进行判断。比如，可以根据历史关联设备的定位参考信息，对待定位设备进行定位。
在一种可能的设计中，该历史定位参考信息包括该一个或多个历史关联设备的位置信息，以及以下中的至少一个：该一个或多个历史关联设备的定位精度或者该待定位设备与该一个或多个历史关联设备保持关联关系的时间信息。基于该方案，在一些实现中，在通过历史关联设备进行定位的过程中，可以根据历史关联设备的位置，对待定位设备进行定位。比如，待定位设备可以位于历史关联设备的位置附近。在另一些实现中，还可以结合历史关联设备的定位精度，明确待定位设备的位置范围。和/或，结合历史关联设备的关联时间，确定待定位设备在与历史关联设备进行交互时的位置，由此结合当前需要定位的时间，对定位结果进行适当的调整(如根据待定位设备的移动属性等进行调整)，由此提升定位准确度。
在一种可能的设计中，在该历史定位参考信息至少包括该一个或多个历史关联设备的位置信息以及该时间信息的情况下，该根据该历史定位参考信息，确定该待定位设备的位置信息，包括：从该一个或多个历史关联设备中，选取时间信息与该定位请求指示的定位时间接近的一个或多个设备作为有效关联设备，根据该一个或多个有效关联设备的位置信息，确定该待定位设备的位置信息。基于该方案，提供了又一种基于历史关联设备进行定位的方案示例。在本示例中，可以从多个历史关联设备中，选取与当前定位时间接近的一个或多个关联设备，对待定位设备进行定位。可以理解的是，与当前定位时间越是接近，那么定位结果就越接近当前待定位设备的位置。因此 通过该方案，能够进一步提升定位的准确度。
在一种可能的设计中，该方法还包括：获取该待定位设备的移动属性，该移动属性用于指示该待定位设备的移动状态。该根据该历史定位参考信息，确定该待定位设备的位置信息，包括：根据该历史定位参考信息以及该移动属性，确定该待定位设备的位置信息。基于该方案，提供了又一种基于历史关联设备进行定位的方案示例。在本示例中，执行本方案的设备(如设备云)还可以从待定位设备获取移动的情况。比如，通过移动属性标识待定位设备的移动情况。可以理解的是，根据历史关联设备确定的位置，更接近在与历史关联设备保持应用关联关系的时间内，待定位设备的位置。结合本方案中的移动属性，就可以对根据历史关联设备确定的位置进行调整，由此获取更加接近当前位置的定位结果。比如，当定位属性指示待定位设备在与历史关联设备交互断开应用关联关系之后，向某个方向移动了一段距离，那么，就可以在根据该历史关联设备确定的定位结果的基础上，向对应方向偏移对应距离，这样就可以获取更加接近当前实际位置的定位结果。

具体实施方式
在电子设备需要定位时，GPS定位是一种常用的方式。示例性的，结合图1。以待定位的电子设备为如图1所示的手机为例。
在进行GPS定位时，手机可以进行搜星，确定能够用于进行定位的卫星(如称为定位卫星)。比如，如图1所示，手机搜星搜索到的定位卫星可以包括卫星1，卫星2以及卫星3。手机可以与各个定位卫星进行通信，以获取与各个定位卫星之间的相对位置信息。示例性的，以相对位置信息包括定位卫星与手机的距离信息为例。手机可以与卫星1进行通信，由此获取与卫星1之间的距离信息1。类似的，手机可以与卫星2进行通信，获取与卫星2之间的距离信息2。手机可以与卫星3进行通信，获取与卫星3之间的距离信息3。根据空间中三个定位卫星各自的经纬度信息，以及手机与各个卫星之间的距离信息(比如距离信息1，距离信息2以及距离信息3)，手机即可计算获取当前所处的位置信息，比如，位置信息可以通过经纬度信息标识。
可以理解的是，在获取电子设备与各个定位卫星之间的相对位置信息之后，电子设备可以根据三角定位法，确定自身的位置信息。根据三角定位法，电子设备需要能够获取至少3个定位卫星对应的相对位置信息。同时，电子设备确定的与各个定位卫星之间的相对位置信息也需要足够准确。
也就是说，在电子设备无法搜索到足够数量的定位卫星时，就会使得电子设备无法获取足够数量的相对位置信息，由此就无法进行定位。另外，在电子设备周边环境较为复杂时，比如电子设备位于环境复杂的城市中，由于楼宇、树木等环境中物体的阻碍，相对位置信息的准确度会大幅下降。这样电子设备也就无法据此进行准确的定位。
为了解决在上述环境中，电子设备无法准确定位的问题，目前，电子设备可以通过与信号源进行通信，由此确定与其他信号源之间的距离，进而结合信号源的位置，确定电子设备的位置信息。其中，信号源可以为与需要进行定位的电子设备进行通信的网络设备，如基站等。示例性的，电子设备可以通过如下3种方案确定与各个信号源之间的距离。
方案1：根据接收信号强度(Received Signal Strength Indication，RSSI)确定。在该方案中，电子设备可以接收来自信号源的信号。电子设备可以根据接收到的不同信 号的信号强度，确定到信号源的大致距离。
方案2：根据飞行时间(Time of Fly，ToF)确定。在该方案中，电子设备可以与各个信号源进行通信，比如发送测量信号。电子设备可以获取测量信号从发出到被各个信号源接收到为止的传播时间。电子设备可以根据各个测量信号的传播时间，以及传播速度(比如传播速度可以约等于光速)，确定电子设备到各个信号源的距离。
方案3：根据飞行时间差(Time Difference of Fly，TDoF)确定。在该方案中，电子设备可以向各个信号源发送测量信号，并通过与各个信号源进行通信，获取测量信号达到各个信号源的时间信息，由此确定测量信号到达各个信号源的时间差。电子设备可以根据该时间差，以及各个信号源中的一个或多个信号源的位置，确定电子设备与各个信号源之间的距离。
在上述示例中涉及的信号源，可以包括能够与电子设备进行通信交互的设备。比如，信号源可以通过无线通信(Wireless Fidelity，Wi-Fi)，蓝牙(Bluetooth)，近距离通信(Near Field Communication，NFC)，蜂窝(Cellular)，红外(InfraRed)，发光二极管(Light Emitting Diode，LED)可见光，超声波，惯导，地磁计算机视觉，超宽带(Ultra-Wide Band，UWB)等机制，建立与电子设备之间的通信。
可以理解的是，通过上述3个方案，电子设备可以与附近的信号源进行通信，由此对自身进行定位。相比于传统的GPS定位，由于信号源可以是在电子设备附近的其他设备，因此电子设备与信号源之间的通信质量不会因为周边环境的复杂程度产生较大误差，由此也就能够提升电子设备的定位精度。同时，由于在大多数场景下，电子设备附近的信号源数量都大于3，因此电子设备能够获取足够数量的与不同信号源之间的距离情况，进而根据三角定位法对自身进行定位。
此外，还可以结合上述3种方案，以及信号的到达角度(Angle of Arrival)信息，进一步确定电子设备与各个信号源之间的相对角度，由此使得电子设备可以更加准确地确定与对应信号源之间的相对位置关系(如相对位置关系可以包括电子设备与信号源之间的空间分布位置以及电子设备与信号源之间的距离等)，进而提升根据相对位置关系确定的定位信息的精确度。
目前，在不同的定位场景下，采用的定位方案可以是不同的。比如，在某商场中，可以采用方案1的机制，即通过RSSI对处于商场中的电子设备进行定位。又如，在商场外某商铺中，可以采用方案2的机制，即通过ToF对商铺中或商铺周围的电子设备进行定位。这样，电子设备就需要在进行定位之前，确定当前场景下的定位机制，并采用对应的定位策略进行定位。比如，在方案1对应的定位场景下，电子设备的定位策略可以为根据RSSI确定与各个信号源之间的距离。而在方案2对应的定位场景下，电子设备的定位策略可以为根据ToF确定与各个信号源之间的距离。这就需要电子设备在处于不同场景下时，多次反复切换定位策略。而在定位场景出现切换的情况时，比如，电子设备从上述示例中的商铺进入商场的情况下，电子设备并不知晓定位机制出现了变化，由此也会产生无法定位的情况发生。另外，而对于一些不支持当前场景下定位机制的电子设备，就无法进行定位。
也就是说，当前的定位方案中，由于定位方案的碎片化，导致电子设备定位受阻，甚至无法进行定位。
为了解决上述问题，本申请实施例提供一种定位方法，能够使得电子设备根据该电子设备所处的具体应用场景和/或所执行的业务等确定关联设备，并根据该关联设备所在的位置实现对自身的定位。本申请实施例提供的方案，由于关联设备是根据电子设备所处的具体场景和/或所执行的业务确定的，因此根据关联设备的位置与电子设备的位置具有关联性。根据关联设备的位置，实现对电子设备的定位，可以避免由于周边环境较为复杂导致的定位不准确或者无法定位的问题。同时也不要求电子设备具备定位能力，因此能够适用于各种电子设备的定位场景中。另外，由于在不同的定位场景中，不存在多种定位策略的切换，也就避免了碎片化的定位方案导致的定位受阻。
以下结合附图对本申请实施例提供的方案进行详细说明。
需要说明的是，本申请实施例提供的定位方法，可以应用在需要定位的电子设备中。在不同的实施例中，该电子设备可以具有不同的实现形式。示例性的，该电子设备可以是手机、平板电脑、个人数字助理(personal digital assistant，PDA)、增强现实(augmented reality，AR)\虚拟现实(virtual reality，VR)设备、媒体播放器等便携式移动设备。该电子设备还可以是智能手环、智能手表等个人穿戴设备。在一些实施例中，该电子设备还可以是应用在智能家居场景下的设备，比如音箱、智慧屏(或称为大屏)、智能插座、智能开关、台灯、空调等。

在一些实施例中，处理器210可以包括一个或多个接口。接口可以包括集成电路(inter-integrated circuit，I2C)接口，集成电路内置音频(inter-integrated circuit sound，I2S)接口，脉冲编码调制(pulse code modulation，PCM)接口，通用异步收发传输器(universal asynchronous receiver/transmitter，UART)接口，移动产业处理器接口(mobile industry processor interface，MIPI)，通用输入输出(general-purpose input/output，GPIO)接口，用户标识模块(subscriber identity module，SIM)接口，和/或通用串行总线(universal serial bus，USB)接口等。
电子设备200可以通过ISP，摄像头293，视频编解码器，GPU，显示屏294以及应用处理器等实现拍摄功能。

可以理解的是，本申请实施例提供的方案，可以用于具有如图2所示组成的电子设备200中。该电子设备200具有定位需求。比如，在一些实施例中，在该电子设备200能够通过GPS定位进行正常定位的情况下，该电子设备200可以通过GPS定位进行定位。在该电子设备200无法通过GPS定位的情况下，该电子设备200可以采用本申请实施例提供的方案进行定位。在另一些实施例中，电子设备200可以在有定位需求的情况下，无论是否可以通过GPS定位，都采用本申请实施例提供的定位方法进行定位。关于本申请实施例提供的方案的具体实施方式，将在后续说明中进行详细介绍。
需要明确的是，上述图2仅为一种电子设备的组成示例。本申请实施例提供的方案，还能够应用于其他具有定位需求的电子设备中。示例性的，在一些实施例中，该电子设备也可以是智能手表等有定位需求的可穿戴电子设备。在另一些实施例中，该电子设备还可以是需要进行定位的传感器等器件，比如，该电子设备可以是如图2所示的传感器模块280对应的独立部件，或者，该电子设备还可以是如图2所示的传感器模块280中的一个或多个传感器对应的独立部件或者集成部件。本申请实施例对该设备的具体形态不作特殊限制。在本申请实施例中，具有定位需求的电子设备也可以称为待定位设备。
在本申请实施例中，对待定位设备的定位，可以是基于待定位设备的关联设备实现的。示例性的，在本申请的一些实施例中，待定位设备的关联设备可以是待定位设 备执行其中安装的一个或多个应用时，在该应用的执行过程中，待定位设备产生应用关联关系的设备。该应用关联关系可以是实现待定位设备安装的应用对应功能的基础。比如，以待定位设备为手机为例。手机在执行扫码应用时，可以与二维码建立应用关联关系，通过与二维码的交互，实现扫码功能。又如，手机在执行支付应用时，可以与收款终端(比如POS机，或者用于收款的二维码等)建立应用关联关系，通过与收款终端的交互，实现支付功能。
需要说明的是，在本示例中，该应用关联关系可以是直接产生的，也可以是间接产生的。例如，继续以待定位设备为手机为例。在支付场景下，手机为了实现支付功能，可以直接与POS机进进行交互，完成支付。那么，在该场景下，POS机就可以是直接与手机建立应用关联关系的设备，也就是说，该POS机可以是手机的关联设备。在另一些场景下，手机的关联设备还可以包括间接与手机产生应用关联关系的设备。比如，在另一些支付场景下，手机为了实现支付功能，其直接的交互对象可以是该场景下的POS机。而在该POS机可能需要通过其他网络节点获取支付信息，才能支持手机完成支付功能。以POS机通过与路由器建立WIFI连接获取支付信息为例。路由器就可以是在手机实现支付功能的过程中，间接地与手机建立应用关联关系的设备。也就是说，该场景下，路由器可以是间接地配合手机实现支付功能的关联设备。
另外，在本申请的另一些实施例中，间接地配合待定位设备实现应用功能的设备，还可以包括并未与待定位设备产生直接的应用关联关系的设备。比如，结合前述示例，在支付场景下，POS机可以作为直接配合手机实现支付功能的设备。如果在该场景下，POS机同时还与其他设备有连接关系，而该连接关系可以不需要支持POS机为手机提供的支付功能。在本示例中，该与POS机具有连接关系的设备，也可以认为是间接地配合手机实现支付功能的关联设备。用于对手机进行定位。
需要说明的是，在本申请的一些实施例中，对于待定位设备的定位，可以是如上述示例中，根据与待定位设备具有应用关联关系的关联设备实现的。在另一些实施例中，还可以结合与待定位设备具有通信连接关系的连接设备，实现对待定位设备的更精准的定位。具体实现方式将在后续说明中详述。
为了使得本领域技术人员能够对本申请实施例中涉及的关联设备有更加清楚的认识和了解，以下对关联设备的确定和可能的实现进行说明。
可以理解的是，在待定位设备的使用过程中，会与其他电子设备(或者电子器件)进行交互，以实现各个场景下的功能。示例性的，以待定位设备为手机为例。在一些场景中，在用户使用手机的付款功能时，手机可以与具有收款功能的销售点(point of sale，POS)终端(简称为POS机)进行交互，以便为用户提供付款功能。在另一些场景中，在用户使用手机的扫码功能时，手机可以在用户的控制下，将摄像头对准二维码进行扫描，由此为用户提供扫码功能。
在本申请实施例中，上述在手机使用过程中，与手机进行交互以便实现各项功能的电子设备或者电子器件，可以称为手机的关联设备。可以看到，在不同的实现场景中，手机的关联设备可以具有多种不同的形态。比如，关联设备可以包括物理设备，如蓝牙信标(Beacon)、手机、平板电脑、电视等。又如，关联设备还可以包括提供各种服务的设备，如二维码、NFC标签、具有AR物体加载能力的设备、打印机、闸 机等。
需要说明的是，在本申请的一些实施例中，手机可以同时具有多个不同的关联设备。结合图3，待定位设备(如手机)可以与关联设备1-关联设备N进行关联。其中N为正整数。示例性的，以支付场景为例。手机可以通过与POS机的交互实现支付功能。那么，POS机就可以是该场景下手机的1个关联设备。在一些场景中，手机还可以与当前店铺中的NFC标签进行交互，以便于与NFC标签所属的设备进行交互，比如获取NFC标签对应的广告信息等。此时，该NFC标签可以是该场景下手机的1个关联设备。
需要说明的是，在本申请的一些实施例中，手机的关联设备还可以与其他设备进行交互。本示例中，与手机直接关联的关联设备(比如图3所示的关联设备1或关联设备2等)就可以称为手机的1级关联设备。对应的，与1级关联设备交互的设备就可以称为手机的2级关联设备。与2级关联设备交互的设备可以称为手机的3级关联设备。以此类推。示例性的，结合图4，以关联设备1与关联设备A，关联设备B以及关联设备C有交互关系为例。那么，对于作为待定位设备的手机而言，1级关联设备可以包括关联设备1-关联设备N。2级关联设备可以包括关联设备A-关联设备C。为了对如图4所示的级联关系进行更加详细的说明，继续以支付场景为例。POS机作为能够直接与手机进行交互的设备，可以包括在手机的1级关联设备中。在一些实施例中，POS机可以与本地的路由器保持无线连接，以便于从网络获取支付信息。那么与POS机连接的路由器就可以包括在手机的2级关联设备中。
在后续说明中，实现待定位设备的一项功能(如支付功能等)的一个或多个关联设备，可以与待定位设备组成待定位设备的1个设备链条。也就是说，设备链条可以用于指示待定位设备和周边其他设备或者服务产生的关系。例如，该关系可以是刷卡、碰一碰、连接WiFi、支付、扫码、登录、搜索、附近(nearby)服务、共享(share)服务等对应的关系。其中，碰一碰可以包括手机读取NFC标签的场景。可以看到，在本申请实施例中，设备链条可以用于指示待定位设备在各个场景下，与周边的其他设备(或物体，或服务)产生的应用关联关系(或简称为关联关系)。该关联关系一般需要待定位设备不远离其他设备。这样，根据具有关联关系的设备(即关联设备)，就可以对待定位设备进行定位。
示例性的，结合图5，待定位设备与关联设备1以及关联设备A可以组成一个设备链条。类似的，待定位设备与关联设备1以及关联设备B可以组成另一个设备链条。待定位设备与关联设备2也可以组成一个设备链条。
采用本申请实施例提供的定位方法，待定位设备可以根据设备链条上各个关联设备(比如1级关联设备和/或2级关联设备)的定位参考信息，确定待定位设备的位置信息，实现对待定位设备的定位。其中，定位参考信息可以包括各个关联设备的位置信息，和/或关联设备的精度信息等。
需要说明的是，待定位设备需要进行定位时，可以自行收集上述关联设备的定位参考信息，进行定位。比如，待定位设备为手机等具有处理功能的设备时，可以自行收集设备链条上各个关联设备的定位参考信息，并由此对自身进行定位。
在另一些实施例中，待定位设备还可以在需要进行定位时，通过云端服务器进行 定位。可以理解的是，对于一些不具备处理能力，或者处理能力较差的待定位设备(如传感器，智能手环等)，可能不具备根据定位参考信息确定自身的位置信息的能力，或者由于协议要求，待定位设备无法自行获取定位参考信息。此时，为了对自身进行定位，待定位设备可以向云端服务器发送定位请求，以便云端服务器根据待定位设备的关联设备的定位参考信息，对待定位设备进行定位。
在该示例中，云端服务器可以用于负责对所有连接到云端服务器的设备进行设备管理。该设备管理可以包括维护注册关系、连接关系、设备状态查询等。在一些实施例中，设备管理也包括设备位置管理。云端服务器可以对外开放设备位置查询接口，允许其他应用或者设备访问特定设备的位置信息。也就是说，云端服务器可以获取待定位设备的设备链条上各个关联设备的定位参考信息。
示例性的，结合图5，在待定位设备需要定位时，可以向云端服务器发送定位请求。云端服务器可以响应于该定位请求，从待定位设备对应的关联设备(如图5所示的1级关联设备以及2级关联设备等)获取各个关联设备的定位参考信息，并据此确定待定位设备的位置信息。
在本申请实施例的具体实现中，云端服务器可以是能够与待定位设备进行通信的网络设备或者节点。在一些实施例中，云端服务器可以是独立的用于支持本申请实施例提供的定位方案的接入网设备(或者接入网设备中的部件)。在另一些实施例中，云端服务器的功能也可以集成在其他为待定位设备提供网络通信服务的设备中。比如，云端服务器的功能可以集成在于待定位设备连接的应用服务器，推送(push)服务器等网络设备中。又如，云端服务器的功能可以集成在于待定位设备连接的家庭网关，路由器等节点中。作为一种可能的实现，云端服务器的功能可以通过设备云(Device clouds)中的相关设备实现。设备云技术主要面向远程数据采集的行业平台应用，可用于终端的大范围组网和管理。涵盖功能包括设备接入、设备管理、数据转发、数据存储、数据展示、数据挖掘、终端认证、运营计费等几部分。以下以云端服务器为设备云中的设备为例进行说明。在以下说明中，设备云中的设备也可以简称为设备云。
以下以待定位设备通过设备云进行定位，待定位设备具有如图5所示的级联关系为例，对本申请实施例提供的定位方法进行说明。如图6所示，该方法可以包括：
S601、待定位设备向设备云发送定位请求。
示例性的，待定位设备可以在有定位需求时，向设备云发送定位请求。其中，定位请求可以用于请求设备云对待定位设备进行定位。
S602、设备云根据定位请求，确定待定位设备的一个或多个关联设备。
其中，待定位设备的一个或多个关联设备可以为待定位设备对应的设备链条上的设备。可以理解的是，在待定位设备对应多个设备链条时，那么设备云可以根据定位请求，确定这多个设备链条上的多个关联设备。
示例性的，设备云可以根据定位请求中的指示待定位设备的设备标识(identification，ID)确定待定位设备对应的设备链条。其中，不同的待定位设备的设备ID不同。结合前述说明，设备云可以负责各个接入到设备云的设备管理。也就是说，设备云能够知晓各个接入设备的关联情况。因此，在待定位设备及其关联设备均接入到设备云的情况下，设备云可以根据待定位设备的设备ID，确定待定位设备的各个设 备链条信息。比如，结合图5，以N等于2为例。请参考图7，设备云可以根据待定位设备的设备ID，确定待定位设备的设备链条可以包括关联设备1对应的设备链条以及关联设备2对应的设备链条。如图7所示，设备云可以确定关联设备1对应的设备链条上还包括关联设备A，关联设备B以及关联设备C。那么，根据待定位设备的设备ID，设备云就可以确定待定位设备的关联设备可以包括：关联设备1，关联设备2构成的1级关联设备，以及由关联设备A，关联设备B和关联设备C构成的2级关联设备。
在本申请的另一些实施例中，设备云还可以根据待定位设备上报的关联信息确定待定位设备的关联设备。在该示例中，设备云在根据定位请求确定待定位设备需要进行定位之外，还可以根据待定位设备发送的关联信息，确定待定位设备的关联设备。其中，关联信息可以是待定位设备在发送定位请求时，与定位请求一同发送的；也可以是待定位设备通过其他的信令向设备云发送的。在本申请的一些实施例中，关联信息可以包括关联设备的设备ID。比如，结合图7，设备云可以接收来自待定位设备的关联信息，该关联信息可以包括关联设备1，关联设备2，以及关联设备A，关联设备B和关联设备C的设备ID。
需要说明的是，在本申请的另一些实施例中，关联设备的关联信息还可以是设备云通过其他形式获取的。比如，在一些特定场景下，待定位设备在出现定位需求时，与其进行交互的关联设备是固定的一个或多个设备，那么这些可能的关联设备的设备标识可以预置在设备云中，这样，设备云就可以在接收到定位请求之后，根据预置的信息，确定待定位设备对应的关联设备。又如，关联设备的关联信息还可以是设备云通过其他与待定位设备相关的设备(如待定位设备的控制设备等)获取的。本申请实施例对于设备云确定关联设备的方式不作限制。
另外，在本申请的一些实施例中，设备云可以在确定待定位设备的关联设备之前，确定待定位设备无法自行进行定位。也就是说，在该示例中，设备云可以在确定待定位设备无法获取自身的位置时，触发执行S602。在本申请的另一些实施例中，即使待定位设备能够获取自身的位置，设备云也可以在接收到定位请求的情况下，触发执行S602以及后续操作，使得设备云可以至少根据本申请实施例提供的方案获取待定位设备的准确位置。
S603、设备云确定关联设备的定位参考信息。
其中，定位参考信息可以包括以下信息中的至少一项：关联设备的位置，关联设备的定位精度等。在一些实施例中，定位参考信息还可以包括关联设备的定位时间，和/或移动属性等。
示例性的，以定位参考信息包括关联设备的位置为例。在一些实施例中，设备云可以确定1级关联设备中，具有定位能力的关联设备的位置。结合图7，在关联设备1具有定位能力的情况下，设备云可以通过与关联设备1的通信，确定关联设备1的位置。类似的，在关联设备2具有定位能力的情况下，设备云可以通过与关联设备2的通信，确定关联设备2的位置。
在本申请的另一些实施例中，在1级关联设备中的各个关联设备都不具备定位能力的情况下，设备云可以获取2级关联设备的位置。比如，在关联设备1和关联设备 2都不具备定位能力的情况下，设备云可以通过与关联设备A，关联设备B和关联设备C中的一个或多个设备进行通信，获取具备定位能力的2级关联设备的位置。比如，以关联设备1和关联设备2都不具备定位能力为例，设备云可以获取能够进行定位的关联设备A，关联设备B和关联设备C中的至少一个关联设备的位置。
需要说明的是，上述示例中是以在1级关联设备不具备定位能力的情况下对2级关联设备进行定位为例进行说明的。在本申请的另一些实施例中，设备云还可以同时获取1级关联设备以及2级关联设备的定位参考信息。
在本申请的一些实施例中，设备云可以在确定关联设备的位置之外，还可以确定各个关联设备的定位精度。其中，关联设备的定位精度可以用于指示关联设备的覆盖范围。可以理解的是，作为待定位设备的关联设备，那么待定位设备的位置应当在关联设备的定位精度范围之内。示例性的，关联设备的定位精度可以通过定位范围来标识。作为一种示例，表1示出了不同关联设备的定位精度的对应关系示例。

示例性的，继续结合图7，以关联设备1为POS机，关联设备2为路由器为例。那么，根据表2，设备云就可以确定关联设备1的定位精度为5cm，POS机的位置为地址A；类似的，设备云可以确定关联设备2的定位精度为100m，路由器机的位置为地址D。
需要说明的是，在本申请的不同实现中，设备云可以通过不同的途径获取关联设备的定位参考信息。示例性的，在一些实施例中，设备云可以从关联设备获取定位参考信息，比如设备云可以通过与关联设备的通信，获取各个关联设备的位置以及定位精度。在另一些实施例中，不同的关联设备的定位参考信息还可以是存储在设备云中的。这样，在设备云确定关联设备之后，就可以通过存储的不同多个定位参考信息，确定对应关联设备的定位参考信息。
S604、设备云根据关联设备的定位参考信息，对待定位设备进行定位。
可以理解的是，作为待定位设备的关联设备，则表明在接收到定位请求时，待定位设备在关联设备附近。本示例中，设备云可以通过与待定位设备对应的关联设备的位置和定位精度，确定待定位设备的位置。
在本示例中，设备云可以参考以下4种情况中分别示出的确定方式，根据定位参考信息，对待定位设备进行定位。
情况1：以设备1为待定位设备为例。设备1和设备0产生关联关系，即设备0为设备1的关联设备。设备0的位置和定位精度范围已知，则设备1的位置＝设备0的位置+误差0。其中，误差0可以为设备0的定位精度范围。可以理解的是，在这种情况下，因为设备1的位置未知，但是设备1和设备0之间产生关联关系，说明设备1一定在设备0附近。所以可以使用设备0的位置作为设备1的位置。但是在设备0的定位精度范围之内，无法确定设备1的具体位置，所以本示例中，可以将设备0的定位精度范围作为设备1定位的误差。需要说明的是，当设备0本身的位置也有误差时，两个误差需要叠加。
情况2：以设备2为待定位设备为例。设备2和设备1产生关联关系，设备1和设备0产生关联关系。即设备1为设备2的关联设备。设备0为设备1的关联设备。 也就是说，对于设备2，设备1为1级关联设备，设备0为2级关联设备。设备0的位置和定位精度范围已知。设备2无法定位，因此可以根据其关联设备(如设备1)对设备2进行定位。在设备1也无法定位的情况下，可以根据设备0的位置确定设备1的位置。在本示例中，设备2的位置可以确定在设备0的附近。但是误差需要叠加设备1定位精度范围对应的误差和设备0定位精度范围对应的误差。即，设备2的位置＝设备0的位置+误差0+误差1。需要说明的是，当设备0自身的定位信息有误差时，误差也需要叠加。
情况3：以设备1为待定位设备为例。设备1和设备0产生关联。即设备0为设备1的关联设备。设备1或者设备0有移动属性，即设备1和设备0存在位置的相对移动。例如设备1和设备0均为手机，在两个手机使用share服务后，两个手机各自向不同方向移动。此时设备1使用设备0的位置时，可以根据移动属性，对设备1的定位结果进行修正，以增加两个设备各自因为移动造成的误差。比如，如果只有一个设备移动，则只需要叠加一个设备的移动误差。又如，如果两个设备均存在移动，那么可以叠加两个设备的移动误差。其中，设备的移动误差可以根据设备的移动速度以及时间计算获取。设备的移动速度可以是设备自行通过传感器获取的，也可以是设备云通过其他手段获取的。
情况4：以设备2为待定位设备为例。设备2在同一时间段内和设备0和设备1产生关联关系。即设备0和设备1均为设备2的关联设备。该情况下，设备2既在设备0的定位精度范围内，又在设备1的定位精度范围内。所以设备2一定在设备0和设备1定位精度范围的交集空间内。所以设备2的位置可以为该交集区域对应的位置。
以下结合实际场景，对上述4种情况下根据定位参考信息对待定位设备进行定位的方法进行详细说明。
在一些实施例中，结合图7，设备云可以根据一个1级关联设备的定位参考信息确定待定位设备的位置信息。其中，待定位设备的位置信息可以根据定位参考信息确定。
示例性的，以关联设备1为POS机为例。请参考图8，为本申请实施例提供的一种定位场景的示意图。如图8所示，待定位设备(如手机)可以在与关联设备1(如图8所示的POS机)进行交互的过程中，向设备云发送定位请求(图中未示出设备云)。设备云确定手机正在进行一笔刷卡交易，确认POS机是手机的关联设备。设备云确定POS机的位置信息。比如通过POS机或者POS机的管理平台，查询POS机的注册地点。由此设备云可以确定POS机的定位参考信息(如POS机的位置是A商户)。根据POS机的定位参考信息，设备云就可以对手机进行定位。可以理解的是，结合表2，POS机的定位精度为5cm以内。设备云还可以根据POS机的定位参考信息确定POS机位于A商户内。因此设备云可以确定手机的位置是A商户，误差小于5cm。
可以理解的是，在手机无法自行定位或者自行定位精度差(比如手机处于楼宇中)时，通过本示例提供的方案，设备云可以将手机的位置缩小到关联设备的定位精度范围内(如本示例中的5cm)，能够实现对于待定位设备的精确定位，而同时不需要引入新的定位协议等，因此对于大部分待定位设备的定位场景均能够较好地适用。
在另一些实施例中，结合图7，设备云可以根据多个1级关联设备的定位参考信 息确定待定位设备的位置信息。其中，待定位设备的位置信息可以根据不同关联设备的定位参考信息共同确定。
示例性的，以关联设备1为POS机，关联设备2为蓝牙信标为例。请参考图9A，为本申请实施例提供的又一种定位场景的示意图。如图9A所示，待定位设备(如手机)可以在与关联设备1(如图9A所示的POS机)以及关联设备2(如图9A所示的蓝牙信标)进行交互的过程中，向设备云发送定位请求(图中未示出设备云)。设备云可以在收到定位请求后，获取POS机以及蓝牙信标的定位参考信息。以定位参考信息包括POS机的位置和定位精度为例。结合表2，设备云可以确定POS机的位置为地址A，定位精度为5cm；以蓝牙信标的位置为地址M，定位精度为10m为例。需要说明的是，表2中的对应关系仅为距离，并未对所有的关联设备进行穷举，比如，在本示例中，关联设备还可以包括蓝牙信标，蓝牙信标的位置可以为地址M，定位精度可以为10m。这样，根据POS机以及蓝牙信标的定位参考信息，设备云就可以确定手机可以位于POS机和蓝牙信标的定位精度范围有重叠的区域之内。因此，手机的定位信息包括POS机的定位精度范围(如地址A周围的5cm范围之内)与蓝牙信标的定位精度范围(如地址M周围的10m范围之内)的重叠区域。如图9A所示，由于POS机的定位精度范围被包括在蓝牙信标的定位精度范围内，因此，上述重叠区域可以为POS机的定位精度范围。也就是说，在该场景下，手机的位置信息可以包括地址A周围的5cm范围之内。
在如图9A的示例中，手机的定位信息可以包括关联设备的定位精度范围中较小的范围。在另一些实施例中，在关联设备的定位精度范围只有部分重合时，也可以根据重叠区域对手机进行定位。
示例性的，请参考图9B。以关联设备1为与待定位设备(如手机1)进行share服务互联的手机2，关联设备2为蓝牙信标为例。在该示例中，手机1可以在与关联设备1(如图9B所示的手机2)以及关联设备2(如图9B所示的蓝牙信标)进行交互的过程中，向设备云发送定位请求(图中未示出设备云)。设备云可以在收到定位请求后，获取手机2以及蓝牙信标的定位参考信息。以定位参考信息包括手机2的位置和定位精度为例。结合表2，设备云可以确定手机2的位置为地址(如地址X)，由于该手机2与手机1有share服务的关系，因此，手机2的定位精度为5m；以蓝牙信标的位置为地址M，定位精度为10m为例。这样，根据手机2以及蓝牙信标的定位参考信息，设备云就可以确定手机1可以位于手机2和蓝牙信标的定位精度范围有重叠的区域之内。因此，手机1的定位信息包括手机2的定位精度范围(如地址X周围的5m范围之内)与蓝牙信标的定位精度范围(如地址M周围的10m范围之内)的重叠区域。结合图9B，设备云可以确定手机1的定位信息包括如图所示的定位区域。
需要说明的是，在本申请的另一些实施例中，关联设备还可以是不属于电子设备的被动装置。比如，NFC标签，二维码等电子标签。可以理解的是，对于NFC标签或者二维码等电子标签，不同于上述示例中POS机或者蓝牙信标等主动提供服务的电子设备，在提供对应服务时，需要用户通过其他电子设备与电子标签进行交互。比如，用户可以在需要获取商品信息时，使用具备“扫一扫”功能的电子设备扫描商品包装上的二维码，以便于电子设备通过分析二维码携带的信息，获取商品的信息。又如， 用户可以在需要通过NFC传输协议获取广告栏的详情信息时，使用具备NFC读取功能的电子设备，与NFC标签进行通信，以便于电子设备通过NFC传输协议读取广告栏的详情信息。
以下以待定位设备的关联设备包括电子标签(如二维码)，以及蓝牙信标为例，对本申请实施例的定位方法进行示例性说明。
可以理解的是，用户想要能够准确地扫描获取二维码上的信息，就需要在一定的范围内对二维码进行扫描。也就是说，当待定位设备的关联设备包括二维码时，作为待定位设备的手机应当处于二维码对应的有效扫描范围之内。二维码的有效扫描范围就可以对应上述示例中的关联设备的有效定位范围。在一些实施例中，二维码可以为静态二维码。比如，该将二维码通过打印张贴在商铺的位置，那么该二维码的位置就是相对固定的，该二维码就可以是静态二维码。在该场景下，二维码的张贴位置可以是用户手动配置的。由此，根据二维码的张贴位置，设备云就可以确定二维码的有效扫描范围。比如，二维码的有效扫描范围可以为以张贴位置为原点，正对二维码的方向上，5米范围内的空间。
结合图10，二维码的有效扫描范围可以为如图所示的扇形区域。另外，蓝牙信标作为手机的1级关联设备，那么手机也会处于蓝牙信标的定位精度范围之内。因此，手机或者设备云就可以根据二维码的有效扫描范围以及蓝牙信标的定位精度范围，确定手机的位置。结合如图6所示的方法，在该场景下，手机可以通过如下方法进行定位：手机可以向设备云发送定位请求；设备云可以在接收到定位请求之后，确定手机的关联设备包括二维码以及蓝牙信标；设备云可以确定二维码以及蓝牙信标的定位参考信息，比如二维码的有效扫描范围以及二维码的位置，蓝牙信标的有效定位范围以及蓝牙信标的位置；设备云可以根据设二维码以及蓝牙信标的定位参考信息，确定待定位设备(如上述说明中的手机)的位置。作为一种示例，设备云可以通过如下步骤，实现对手机的定位：步骤1：设备云接收到对手机的定位请求，设备云确认手机自身无法定位。步骤2：设备云确定手机检测到蓝牙Beacon，同时确定手机发生扫码活动，确认蓝牙Beacon和二维码是手机的关联设备。步骤3：设备云确定蓝牙Beacon和二维码的位置信息。其中，蓝牙beacon以及二维码的位置信息可以通过蓝牙Beacon以及二维码的管理平台或者签发机构确定。步骤4：设备云确定蓝牙Beacon的位置(比如在某门店入口处)，覆盖范围为10m。二维码的位置为该门店收银台处，覆盖范围为5m的扇形区域。步骤5：设备云确定手机必须同时在蓝牙Beacon的覆盖范围和二维码的覆盖范围内，所以设备一定在如图10所示的定位区域。
结合上述图8-图10的说明，本领域技术人员应当能够理解，在待定位设备的1级关联设备中的一个或多个具备定位能力(对应前述说明中的情况1和情况4)的情况下，采用如图6所示的方法时可以准确快速地对待定位设备进行定位。
需要说明的是，在图6示出的实施例中，以设备云获取待定位设备的位置信息为例进行了说明，在本申请其他可能的实施例中，如果待定位设备自身即具有根据与其关联的设备确定当前所处位置的能力，则图6所描述的各方法步骤也可以由该待定位设备完成，而不需要设备云执行。
以下结合附图对待定位设备的1级关联设备都不具备定位能力的情况下，本申请 实施例提供的定位方法(即如图6所示的方案)的具体实施进行示例性说明。
应当理解的是，在向待定位设备提供服务的过程中，并不要求所有的关联设备都具备定位能力。在本申请实施例中，在设备云无法确定第1级关联设备的定位参考信息的情况下，设备云可以确定2级关联设备，或者3级关联设备等其他关联设备的定位参考信息，并据此对待定位设备进行定位。其中，2级关联设备可以是与1级关联设备交互的设备。类似的，3级关联设备可以是与2级关联设备交互的设备。
示例性的，结合图11，以待定位设备为手机，1级关联设备为POS机为例。设备云接收到对手机的定位请求可以确定手机正在进行一笔刷卡交易，由此确认POS机是手机的关联设备。设备云可以确定POS机的定位参考信息。比如，设备云可以通过POS机或者POS机的管理平台，查询POS机的注册地点。设备云在确定POS机无法定位时，确定POS机连接了路由器的WiFi信号，由此确定路由器是POS机的关联设备，因此路由器是手机的2级关联设备。该路由器与POS机之间的关联是基于通信连接而产生的通信连接关系。设备云可以确定路由器的定位参考信息。比如设备云通过WiFi注册信息或者WiFi路由器供应商确定WiFi路由器位于A商户。根据路由器的定位参考信息，设备云可以确定手机的位置在A商户附近。由于POS机的定位精度不到5cm。路由器的定位精度大约为100m。所以设备云可以确定手机的位置是A商户，误差100m。
可以理解的是，上述示例中，是以1级关联设备不具备定位能力，2级关联设备具备定位能力为例进行说明的。在本申请的另一些实施例中，在2级关联设备也不具备定位能力时，设备云可以根据与2级关联设备相关的其他设备(如3级关联设备或4级关联设备等)，对待定位设备进行定位，其具体执行方式与上述示例类似，此处不再赘述。
需要说明的是，上述示例中，是以1级关联设备是能够直接与待定位设备交互的设备，2级关联设备是能够直接与1级关联设备交互的设备为例进行说明的。在本申请的另一些实施例中，1级关联设备和/或2级关联设备还可以具有不同的区分。示例性的，以有多个设备可以同时与待定位设备进行交互为例。在一些实现中，这多个设备由于都可以直接与待定位设备进行交互，因此可以作为待定位设备的1级关联设备。在另一些实现中，设备云可以根据这些关联设备各自的精度范围，各个关联设备与当前待定位设备所处场景的耦合情况(如该关联设备是否可以提供当前场景下的服务)等，对这些关联设备进行区分。比如，将定位精度范围小于对应的预设阈值，并且能够提供当前场景下的服务的关联设备定义为1级关联设备。设备云可以根据这些1级关联设备对待定位设备进行定位。其具体方案可以参考上述示例中的情况1-情况4的说明，此处不再赘述。
可以理解的是，通过本申请实施例提供的方案，能够对待定位设备进行定位。在一种实现场景中，可以通过本申请实施例提供的方案(如图6所示的方案)对待定位设备进行定位，可以实现对用户的定位，进而根据用户的位置，实现对应场景中的功能。
示例性的，以智慧生活场景为例。在智慧生活场景中的各个智能服务可以由智慧系统负责调控。在一些实现中，该智慧系统可以是具备对该场景下各个智能设备进行控制管理的中枢。本示例中的智慧系统(简称为系统)可以对应到上述说明中的设备 云。
作为一种可能的实现，系统可以通过对用户进行定位(比如确定用户具体处于哪一个房间)，实现该场景中的一些智慧能力。比如，当系统接收到用户“开灯”的指令时，可以结合用户所处房间的信息，点亮对应房间的照明设备。
在本示例中，系统可以通过对用户佩戴或使用的电子设备进行定位，实现对用户的定位。比如，以系统通过用户佩戴的智能手表对用户进行定位为例。即智能手表为待定位设备。
结合图6所示的方案，在需要对智能手表进行定位时，系统发起对智能手表的定位。一般而言，智能手表在位于室内环境下时，无法对自身进行精确的定位。在本示例中，在智能手表接收到系统的定位指示的情况下，检测当前能够搜索到的蓝牙/WIFI设备。比如，结合图12，智能手表可以检测到智能音箱、多个路由器(如R1-R5)等设备。在一些实施例中，智能手表可以根据各个设备到智能手表的距离，判断与智能手表距离最近的关联设备。示例性的，智能手表可以通过向各个设备发送检测信号，根据检测信号的RSSI或者其他参数，确定距离最近的关联设备。比如，在如图12所示的场景下，系统可以确定与智能音箱的距离最近。那么，智能手表就可以将智能音箱作为其1级关联设备。
系统可以从智能手表处获取关联设备的信息(比如智能音箱的设备ID)，并确定智能音箱的定位参考信息。在一些实施例中，在智能音箱具备定位能力的情况下，系统可以根据智能音箱的定位参考信息(如智能音箱的位置等)，确定智能手表的位置范围。结合预设的用户对应的户型图，系统就能够确定智能手表具体所处房间。其中，智能音箱的位置可以是用户自行配置的，也可以是智能音箱或系统通过定位确定的。在另一些实施例中，在智能音箱不具备定位能力的情况下，系统可以确定与智能音箱关联的2级关联设备(如图12所示的路由器R1-R5)。系统可以结合R1-R5的位置，结合场景下的户型图，确定不同路由器与房间的对应关系。接着，根据各个路由器的有效定位精度范围，以及各个路由器的位置，系统就可以确定智能音箱的位置。比如，系统可以确定音箱位于R1-R3的定位精度范围的交叉区域，那么系统就可以据此确定智能音箱位于房间A中。
在确定了智能手表位于房间A中之后，系统就可以确定用户当前处于房间A中。这样，当系统接收到用户的指令，比如通过语音指令“开灯”，就可以打开房间A中的照明设备。
结合前述说明，设备云可以在接收到待定位设备的定位请求的情况下，获取当前关联设备的定位参考信息，并据此对待定位设备进行定位。在一些实施例中，如果待定设备需要知晓自身的定位结果，那么设备云可以在确定待定位设备的位置信息之后，将该位置信息发送给待定位设备。
可以理解的是，在一些实施例中，待定位设备可能是移动的，或者，待定位设备在发起定位请求时，并没有与任何设备进行交互，也就不存在关联设备。在这些场景下，本申请实施例还提供一种定位方法，能够实现对待定位设备的定位。
示例性的，请参考图13，为本申请实施例提供的又一种定位方法的示意图。如图13所示，该方法可以包括：
S1301、待定位设备向设备云发送定位请求。
该步骤与如图6所示的S601类似，此处不再赘述。需要说明的是，在本示例中，由于待定为设备在发出定位请求时，可能没有对应的关联设备。因此，为了使得设备云可以根据历史交互情况对待定位设备进行定位，该定位请求中可以包括发送定位请求的时间。
S1302、设备云根据定位请求，确定待定位设备的历史关联设备。
S1303、设备云确定历史关联设备的定位参考信息。
在本示例中，设备云可以确定待定位设备在发起定位请求之前一段时间之内的关联设备的情况。比如，在待定位设备发送定位请求之前，可以在不同时刻分别与不同的关联设备进行了交互，那么设备云就可以分别获取这些关联设备的信息。
示例性的，表3示出了一种设备云确定的历史关联设备的定位参考信息的一种示例。

如表3所示，相较于前述说明中的表2，设备云可以知晓在历史交互过程中，各个关联设备与待定位设备的交互有效时间。通过如表3所示的定位参考信息，设备云就可以确定各个历史关联设备的定位参考信息的有效性。比如，在设备云接收到的定位请求携带的时间为22:05时，则根据表3，设备云可以知晓距离接收到定位请求的时刻最近的交互是与连接设备的交互。也就是说，由于时间最为接近，待定位设备的位置与连接设备的位置最为接近。这样，设备云就可以根据连接设备的位置和定位精度确定待定位设备的位置。在另一些实施例总，设备云可以选取与定位请求携带的时间较为接近的多个关联设备的定位参考信息作为有效的定位参考信息，以便结合这些关联设备的定位参考信息，对待定位设备进行定位。其中，多个关联设备的选取，可以是设备云自行根据间隔时间的长短自行确定的，也可以是设备云根据预设的数量选取的，也可以是设备云根据用户的历史习惯确定的。
需要说明的是，在一些实现中，如表3所示，在该对应关系中，还可以包括各个历史关联设备提供的业务信息。比如，通过表3，设备云可以确定POS机提供的业务为刷卡支付。又如，通过表3，设备云可以确定闸机提供的业务为地铁公交扫码。又 如，通过表3，设备云还可以确定连接设备提供的业务为共享热点。
S1304、设备云根据历史关联设备的定位参考信息，对待定位设备进行定位。
示例性的，设备云可以根据有效的定位参考信息，对待定位设备进行定位。
在一些实施例中，以设备云根据与接收到定位请求中的时间最为接近的交互作为有效的定位参考信息为例。比如定位请求中的时间为22:05，那么设备云就可以将连接设备的定位参考信息作为有效的定位参考信息。这样，设备云就可以确定待定位设备的位置在地址L的10m范围之内。
在另一些实施例中，以设备云根据与接收到定位请求中的时间最为接近的3个交互作为有效的定位参考信息为例。比如定位请求中的时间为22:05，那么设备云就可以将PC或平板，打印机，连接设备的定位参考信息作为有效的定位参考信息。这样，设备云就可以将多个定位参考信息指示的交叉区域作为待定位设备的定位结果。比如，设备云可以将地址J周围1m范围，地址K周围50cm范围，以及地址L的10m范围的较差区域，作为待定位设备的定位结果。
需要说明的是，通过上述方案，设备云确定的位置实际上是待定位设备在一段时间之前的位置。因此，在一些实施例中，设备云还可以根据历史关联设备的定位参考信息，确定待定位设备的移动属性。比如，该移动属性可以包括待定位设备可能的移动方向，和/或移动距离等。作为一种可能的实现，在确定待定位设备的当前位置时，设备云可以根据不同的历史关联设备的定位参考信息，确定待定位设备的移动属性。示例性的，待定位设备的移动属性，可以是设备云根据各个历史关联设备的交互时间，以及各个历史关联设备的位置确定的。比如，结合表3，设备云可以根据表3确定，在20：21-20：22这段时间内，待定位设备在使用打印机提供的扫码打印服务。在21:00-22:00这段时间内，待定位设备在使用连接设备提供的共享热点服务。由此，设备云就可以确定地定位设备的移动属性为沿着打印机到连接设备所指向的方向。结合连接设备的位置，或者连接设备和打印机的定位参考信息，设备云就可以确定待定位设备位于定位参考信息所指示区域中，上述方向所在的方位。
在本申请的另一些实施例中，设备云还可以从待定位设备获取待定位设备的移动属性。示例性的，待定位设备的移动属性可以是根据待定位设备中设置的加速度传感器，陀螺仪传感器等能够辨别方向和速度的传感器确定的。设备云可以从待定位设备获取其移动属性，并结合历史关联设备的定位参考信息，对待定位设备进行定位。
请参考图14，以待定位设备为手机为例。如图14所示，手机可以在T1时刻与POS机进行交互，在T1时刻之后的T2时刻向设备云发送定位请求。由于在T2时刻，手机不存在关联设备，因此，设备云参考如图13所示的方案，确定手机的历史关联设备(如POS机)。在一些实施例中，设备云还可以确定手机当前的移动属性，比如手机通过其中设置的加速度传感器可以确定正在以1米每秒的速度移动，设备云可以从手机获取该移动属性，进而确定手机当前的位置为：以POS机的位置为中心，定位精度范围周边的位置。根据手机的移动速度，结合定位请求中的时间以及与POS机交互的时间确定手机的定位信息。示例性的，以手机在发出定位请求之前2分钟与POS机进行过支付交互为例，设备云可以根据如下步骤，实现对手机的定位：步骤1：设备云接收到对手机的定位请求，设备云确认手机自身无法定位。步骤2：设备云确定手 机2分钟前进行过一笔刷卡交易，确认POS机是手机的关联设备。步骤3：设备云确定POS机的位置信息。步骤4：设备云确定POS机的位置是A商户。步骤5：设备云根据POS机的位置确定手机的位置是A商户。在一些实施例中，设备云可以结合手机的移动属性，对手机的定位结果进行调整。比如，设备云根据手机的移动属性，确定手机在2分钟时间内最多移动50m。那么设备云可以确定手机的位置是A商户，误差为50m。
需要说明的是，如果按照移动速度和移动时间估算，手机已经移动出了关联设备的定位精度范围，那么设备云可以按照手机移动的距离，结合关联设备的位置重新确定手机的位置。
在本示例中，设备云从待定位设备获取的移动属性，可以包括如上述示例中所示的待定位设备通过其中设置的传感器所采集的全量的数据。在获取该移动属性之后，设备云可以对该移动属性中包括的全量的数据进行处理，由此获取待定位设备的移动情况。在另一些实施例中，设备云从待定位设备获取的移动属性，也可以包括待定位设备对传感器所采集的全量的数据处理之后的数据。该处理之后的数据可以用于指示待定位设备的移动情况。由此，在待定位设备侧进行数据的处理，能够有效地减小与设备云之间的数据传输量。
另外，以上针对图13的说明中，均是以当前待定位设备没有关联设备为例的。在另一些实施例中，在当前待定位设备存在关联设备，设备云依然可以采集待定位设备的历史关联的信息。在对待定位设备进行定位时，设备云可以结合历史关联设备的定位参考信息，对根据当前的关联设备确定的位置进行调整，以使得定位结果更加符合待定位设备的使用逻辑，由此进一步提升定位准确度。
上述示例中，设备云可以根据历史关联设备对待定位设备进行定位。在本申请的一些实施例中，在待定位设备需要进行定位时，如果当前环境中没有关联设备，则设备云还可以等待待定位设备与其他设备进行交互时，再对待定位设备进行定位。
示例性的，设备云可以在接收到手机定位请求时，确定当前环境中没有关联设备的情况下，进入等待(pending)状态。设备云可以实时获取手机的交互情况，以便于在出现关联设备时，根据该关联设备的定位参考信息对手机进行定位。作为一种示例，请参考图15，以手机在T3时刻发送定位请求，环境中没有关联设备；手机在T3时刻之后的T4时刻与NFC标签进行交互为例。设备云可以通过如下步骤，对手机进行定位：步骤1、设备云接收到对手机的定位请求，设备云确认手机自身无法定位。步骤2、设备云确定手机当前没有关联设备，或者关联设备历史经过时间太长已经没有参考价值。设备云挂起设备定位请求。步骤3、设备云确定设备扫描NFC标签。步骤4、设备云确定NFC标签的定位参考信息，比如NFC标签位于某门店体验台处。步骤5、设备云确定手机的位置在NFC标签处，并恢复挂起的设备定位请求，返回定位结果。其中，步骤5中，设备云根据NFC标签对手机进行定位的具体执行方式，可以参考图13或图6所示的方案，此处不再赘述。
上述主要从设备的角度对本申请实施例提供的方案进行了介绍。为了实现上述功能，其包含了执行各个功能相应的硬件结构和/或软件模块。本领域技术人员应该很容易意识到，结合本文中所公开的实施例描述的各示例的单元及算法步骤，本申请能够 以硬件或硬件和计算机软件的结合形式来实现。某个功能究竟以硬件还是计算机软件驱动硬件的方式来执行，取决于技术方案的特定应用和设计约束条件。专业技术人员可以对每个特定的应用来使用不同方法来实现所描述的功能，但是这种实现不应认为超出本申请的范围。
本申请实施例可以根据上述方法示例对其中涉及的设备进行功能模块的划分，例如，可以对应各个功能划分各个功能模块，也可以将两个或两个以上的功能集成在一个处理模块中。上述集成的模块既可以采用硬件的形式实现，也可以采用软件功能模块的形式实现。需要说明的是，本申请实施例中对模块的划分是示意性的，仅仅为一种逻辑功能划分，实际实现时可以有另外的划分方式。
请参考图16，为本申请实施例提供的一种定位装置1600的组成示意图。该定位装置1600可以用于对待定位设备进行定位。比如，该定位装置1600可以设置在如图5所示的云端服务器(如设备云)中。
