下面基于前述图1-3提供的系统架构以及电子设备，对本申请提供的一种设备搜寻方法进行详细介绍。
首先，参阅图4，本申请提供的一种设备搜寻方法的流程示意图，如下所述。
401、第一设备获取第二设备的位置信息。
其中，第一设备可以根据第二设备的位置信息获知第二设备所在的位置。第一设备获取第二设备的位置信息的方式可以有多种，具体地，第一设备可以从存储的数据中查找到该第二设备的位置信息，也可以是在与第二设备建立连接之后，接收到第二设备发送的位置信息，或者在第二设备向第三设备发送位置信息之后，由第三设备将该位置信息转发至第一设备等。
例如，在一些场景中，用户家庭中包括了手环、手机、平板和智慧大屏等电子设备，当多个电子设备接入同一个网络或者互相建立连接之后，每个电子设备可以向同一个或者内的其他电子设备或者与其连接的电子设备周期性地发送自身的位置信息，如每隔5秒手环可以向平板或者手机传输自身的位置坐标，或者每隔5秒向处于同一网络内的所有电子设备发送自身的位置坐标。
具体例如，在一个可能的场景中，用户的手环在家中的某个角落向平板电脑发送一次位置信息之后即因无剩余电量而关机。在此之后，用户手持手机进入家中，手机接入家庭局域网，若用户需要通过该手机搜寻手环的位置，则处于同一局域网的平板电脑可以将手 环的位置发送至手机。
402、第一设备根据自身的位置信息以及第二设备的位置信息获取第二设备与第一设备的相对位置。
在第一设备获取到自身的位置信息以及第二设备的位置信息之后，可以计算第二设备与第一设备的相对位置，该相对位置可以包括第二设备相对于第一设备的方向和距离等。
例如，第一设备可以读取自身的位置，并接收到第二设备的位置，然后以第一设备为中心建立坐标系，计算第一设备自身的位置和第二设备的位置的差值，得到第二设备在该坐标系中的位置，从而得到第二设备在坐标系中的位置向量，即可计算得到第二设备相对于第一设备的方向和距离。
403、判断第一设备是否具有拍摄功能，若是，则执行步骤404，若否，则执行步骤408。
其中，步骤403为可选步骤。例如，在第一设备确定需要搜寻的第二设备时，可以获取第一设备的设备属性，该设备属性可以包括但不限于第一设备的外观、设备类型或者设备具备的功能等信息。因此，在确定需要搜寻的第二设备时，即可读取到第一设备是否具备拍摄功能。
为便于理解，可以简单理解为，可以判断第一设备是否具有前述的摄像头193，若第一设备具备摄像头，则可以继续判断第二设备是否在第一设备的拍摄范围内，即执行步骤404。若第一设备不具备摄像头，则可以基于第二设备与第一设备的相对位置进行提示，即指示第二设备相对于第一设备的位置或者方向等，即执行步骤408。
404、判断第二设备是否在第一设备的拍摄范围内。
在确定第二设备具有拍摄功能时，可以根据第二设备与第一设备的相对位置，判断该第二设备是否在第一设备的拍摄范围内。若第二设备在第一设备的拍摄范围内，则第一设备可以直接拍摄包括了第二设备的第一图像，即执行步骤406，若第二设备不在第一设备的拍摄范围内，且第二设备可以移动，则可以提示朝向第二设备移动，以使第二设备在第一设备的拍摄范围内。
例如，拍摄范围可以如图5所示，摄像头的拍摄范围即前述的预设范围，与摄像头的视场角α相关。通常，摄像头的视场角越大，拍摄范围也就越大，视场角越小，拍摄范围也越小。
405、第一设备指示朝向第二设备移动第一设备。
其中，当第二设备不在第一设备的拍摄范围内，且第一设备可移动时，则可以指示第一设备朝向第二设备移动，从而使第二设备处于第一设备的拍摄范围内。

并且，在第一设备移动的过程中，可以实时更新第二设备与第一设备的相对位置，并实时更新指示移动第一设备的提示信息的内容，如可以根据实时更新的相对位置，实时更 新显示界面中显示的朝向第二设备移动的方向或者距离等。
406、第一设备拍摄第一图像。
其中，若第二设备在第一设备的拍摄范围内，则第一设备可以启动摄像头进行拍摄，得到第一图像。
通常，若第二设备未被遮挡，则第一设备可以对第一设备进行图像识别，确定第二设备在第一图像中的哪个区域，或者，若第二设备被遮挡，则第一设备可以结合第二设备和第二设备的相对位置，确定第二设备在第一图像中的哪个区域。
可选地，若第一设备进行图像识别确定第二设备在第一图像中的哪个区域，则在进行图像识别之前，第一设备可以获取第二设备的设备属性，如第二设备的设备类型、外观或者大小等，从而可以根据该第二设备的设备属性，来对第一图像进行识别，准确识别出第二设备所在的区域。
407、第一设备在显示屏中突出显示第一图像中第二设备所在的区域。
其中，若第一设备具有显示屏或者与显示屏连接，在得到第一图像，并确定第二图像在第一图像中的区域之后，可以在显示屏中突出显示第二设备在该第一图像中的区域。
可选地，第一设备还可以在显示屏中显示全部或者部分第一图像。
具体地，可以直接在显示第一图像的基础上，通过热力图的形式表现出第二设备所在的区域，或者，通过标记框、箭头、文字等信息在第一图像中标记出第二设备所在的区域。
408、第一设备对第二设备与第一设备的相对位置进行提示。
其中，可以通过提示信息的形式来提示第二设备相对于第一设备的位置。例如，若第二设备不具备拍摄功能，则可以对第二设备与第二设备的相对位置进行提示。或者，又例如，若第一设备具备拍摄功能，但第二设备不在第一设备的拍摄范围内，且第一设备不可移动，则也可以对第二设备与第二设备的相对位置进行提示。又例如，若第二设备在第一设备的拍摄范围内，在显示屏中突出显示第一图像中第二设备所在的区域的基础上，还可以进一步对第二设备与第一设备的相对位置进行提示，以使用户可以更准确的找到第二设备，提高用户体验。
具体地，相对位置中可以包括第二设备相对于第一设备的第一距离，或者第二设备相对于第一设备的第一方向等。则步骤408可以包括：对该第一距离和/或第一方向进行提示。

其中，若设备A和设备B建立了通信连接，则设备A和设备B可以通过建立的通信连接，互相发送定位信息，以互相通知各自所在的位置。
例如，如图7所示，设备A可以是手环，设备B可以是手机，手环和手机之间建立了UWB连接，手环可以通过该UWB连接，将自身的位置传输至手机中，以使手机获知到到手环的位置。可选地，可以在手机的显示界面中显示手环的位置，以使用户可以在手机的显示界面中直观地观察到手环的位置。
此外，在一些场景中，设备A和设备B之间可能并未建立连接，则设备B可以通过其他设备来获取设备A的位置信息。例如，在一些场景中，设备A可以是手环，设备B可以是手机。如图8所示，手环和智慧大屏之间建立了UWB连接，手环通过该UWB连接将自身的位置信息发送给智慧大屏，如图9所示，智慧大屏与手机建立了WiFi连接，由智慧大屏将手环的位置信息发送至手机，以使手机获知手环的位置。具体例如，在一些场景中，手环在用户家中的某个角落与智慧大屏建立了连接，并将自身的位置信息发送至智慧大屏，随后手环因电量不足而关机。当用户手持手机回家时，该手机可以与智慧大屏通过WiFi建立连接，智慧大屏可以将手环最后一次发送的位置信息发送给手机，从而使手机在未与手环建立连接的情况下，也可以获取到手环的位置信息，后续可以基于该位置信息对手环的位置进行提示，使用户在未与手环建立连接的情况下也能找到手环，提高用户体验。
603、用户在设备B上提出寻找设备A。
其中，本申请对步骤603和步骤601的执行顺序不作限定，可以先执行步骤601，也可以先执行步骤603，本申请仅以先执行步骤601为例进行示例性说明，并不作为限定。
具体地，用户可以在设备B上进行操作，从而指示设备B寻找设备A。
例如，一种GUI如图10所示，可以在设备B的触摸屏中显示接入了同一局域网的设备，如手机、手环、耳机、手写笔等，用户可以在触摸屏上进行选择操作，选择需要搜寻的设备。
在一些可能的场景中，设备B中可能不具有显示屏而具有扬声器和麦克风等，则用户可以通过语音的方式控制设备B寻找设备A。例如，设备B可以是智能蓝牙音响，用户在唤醒该蓝牙音响之后，可以对蓝牙音响发出语音控制指令，如“搜寻手环”、“搜寻手机”等指令，来控制蓝牙音响开始搜寻设备A。
604、设备B计算设备A的相对位置。
在确定需要搜寻的设备A之后，根据获取到的设备A的位置信息，计算设备A相对于设备B的相对位置。如设备A相对于设备B的方向、距离、高度等。
例如，可以使用各类同步定位与建图(simultaneous localization and mapping，SLAM)算法计算设备A与设备B的相对位置。
为便于理解，计算该相对位置的方式可以简单理解为，可以以设备B为中心建立坐标系，并计算设备A的位置和设备B的位置之间的差值，基于该差值确定设备A在该坐标系中的坐标向量，从而得到设备A相对于设备B的方向和距离。
需要说明的是，以下步骤604-616由设备B来执行。
605、判断设备B是否具有拍照功能，若否，则执行步骤606，若是，则执行步骤609。
其中，判断设备B是否具有拍照功能，即判断设备A是否具有摄像头，若具备摄像头，则可以继续判断设备A是否在设备B的视野内，即执行步骤609，若设备B不具有摄像头，则可以通过其他方式对设备A的位置进行提示，如执行步骤606。
应理解，步骤605为可选步骤，在一些设备B具有拍摄功能的场景中，可以无需执行判断步骤，而直接进行下一步。
此外，本申请对步骤605和604的执行顺序不作限定，可以先执行步骤604，也可以先执行步骤605，还可以同时执行步骤604和步骤605等，具体可以根据实际应用场景进行调整，此处仅以先执行步骤604为例进行示例性说明，并不作为限定。
606、判断设备B是否具有显示功能，若是，则执行步骤607，若否，则执行步骤608。
当设备B不具备拍照功能时，可以继续判断设备B是否具备显示功能，即是否具有或者连接有显示屏，若设备B不具备显示功能，则可以通过语音提示的方式来提示设备A相对于设备B的相对位置，即执行步骤608。若设备B具备显示功能，则即可以选择显示的方式，也可以选择语音提示的方式来对设备A相对于设备B的相对位置进行提示。
607、显示位置指向图。
具体地，可以在设备B的显示屏或者与设备B连接的显示屏中显示位置指向图，该位置指向图用于指示设备A相对于设备B的位置，如设备A和设备B之间的距离以及设备A相对于设备B的方向等。
示例性地，一种GUI如图11所示，可以在设备B的显示界面中，通过箭头的形式指示设备A在设备B的哪个方向，并通过文字的形式指示设备A与设备B的距离。又例如，一种GUI如图12所示，可以在设备B的显示界面中，通过箭头的形式指示设备A在设备B的哪个方向，并通过文字提示用户朝该方向移动的距离。
还例如，设备B可以是手环，一种GUI如图13A所示，可以在手环中，通过表盘的形式，指示设备A相对于手环的方向，并通过文字的形式显示设备A与手环的距离为2.7米。又例如，一种GUI如图13B所示，设备B可以是智慧大屏，可以在屏幕中提示“您的“手环”在右方3米”，以向用户指示在智慧到的右方3米寻找手环。
608、语音提示。
当设备B不具备拍照功能时，也不具有显示屏时，可以通过语音提示设备A相对于设备B的位置和方向，或者，当用户选择语音提示时，可以通过语音提示设备A相对于设备B的位置和方向。因此，即使在设备B不能拍摄也不能显示的场景中，也可以通过语音来提示设备A的位置，使用户可以通过语音快速找到设备A，提高用户体验。
例如，如图14所示，设备B可以是蓝牙音响，该蓝牙音响可以播放语音，通过语音的形式指示需要搜寻的设备相对于蓝牙音响的距离或者方向等。
609、判断设备A是否在设备B的视野中，若是，则执行步骤610，若否，则执行步骤613。
具体地，在确定设备B具备拍照功能时，可以根据设备A与设备B的相对位置，判断设备A是否在设备B的视野(即拍摄范围)中，若是，则设备B可以拍摄图像，若设备A不在设备B的视野中，则可以提示移动设备B，从而使设备A在设备B的视野中。
例如，以设备B为手机为例，如图15所示，该手机以自身为中心建立有一个坐标系，坐标系原点为手机的几何中心。坐标系Z轴垂直手机屏幕指向手机背面，坐标系Y轴指向与手机的长边平行，坐标系X轴与手机的短边平行。设备B的拍摄系统，如后置摄像头，位于X轴和Y轴的负值的位置，且该摄像头有固定的视野，例如水平视野120°，垂直视野90°，摄像头的光轴与坐标系的Z轴平行；摄像头的水平方向与坐标系的X轴平行，与Y轴垂直；摄像头的垂直方向与坐标系的Y轴平行，与X轴垂直。
设备A在设备B的坐标系位置为(X1,Y1,Z1)，根据设备B的坐标系原点与设备B摄像头的位置差(X2,Y2,Z2)，计算出设备A在设备B的摄像头坐标系中位置为(X3,Y3,Z3)。X3＝X1+X2，Y3＝Y1+Y2，Z3＝Z1+Z2。设备A在设备B的摄像头中的水平角度为arctan(X3/Z3)，垂直角度为arctan(Y3/Z3)。如果设备A的水平角度大于水平视野/2,即|arctan(X3/Z3)|>(120°/2)或垂直角度大于垂直视野/2，即|arctan(Y3/Z3)|>(90°/2)，则设备A在设备B视野外。
610、拍摄图像。
其中，在确定设备A在设备B的视野内时，设备B即可启动摄像头，拍摄图像。该图像中包括了设备A所在的区域。
611、识别设备A在图像中的位置。
在拍摄到包括了设备A所在的区域的图像之后，可以通过图像识别，识别出设备A在该图像中的区域。
在一种可能的实施方式中，可以通过canny边缘检测、深度学习检测算法、支持向量机(support vector machines,SVM)等算法识别图像中包括的设备A，从而得到设备A在图像中的区域。
在另一种可能的实施方式中，可以根据设备A与设备B的相对位置，确定设备A在图像中的区域。即直接将设备A与设备B的相对位置，转换为在图像中的坐标。例如，在一些场景中，设备A可能被物体遮挡，从而拍摄到的图像中无法识别出设备A，此时，可以结合设备A相对于设备B的位置，将设备A的位置标定至摄像头的坐标系中，然后将设备A在摄像头的坐标系中的位置，投影到图像中的位置，从而确定出设备A在图像中的区域。
在另一种可能的实施方式中，可以结合设备A与设备B的相对位置，以及图像识别，确定设备A在图像中的位置。
具体地，在通过设备A与设备B的相对位置，计算出设备A在图像中的位置后，从图像中截取包括了设备A的部分区域来进行图像识别，从而确定设备A在设备B拍摄到的图像中的区域。
例如，获知设备A相对于设备B的距离和朝向之后，设备B带有摄像头，需要将设备A的位置坐标标定至摄像头的坐标系中。然后，将设备A在摄像头的坐标系中的位置，转换为图像中的坐标系的位置。如转换方式可以包括：
Figure PCTCN2021081517-appb-000003
其中，Z c代表被拍摄物体到摄像头的距离，u代表图像中被拍摄物体的横坐标，v代表图像中被拍摄物体的纵坐标，d x,d y为相机横向、纵向像元尺寸，u 0,v 0为图像横纵中心，f为摄像头的焦距，R为一个3X3的矩阵，代表定位系统坐标系与摄像头坐标系之间的旋转矩阵，T为3X1的矩阵，代表定位系统坐标系与摄像头坐标系之间的平移矩阵，X w,Y w，Z w是设备A在的位置。
在获知设备A在图像中的位置之后，以此位置为中心截取部分图像，进行对设备A的识别，从而减少对图像的全局检测所需的计算。
612、突出显示设备A在图像中的位置。
在确定设备A在图像中所在的区域之后，可以突出显示该区域，以提示用户设备A在图像中的区域，从而使用户可以根据图像中突出显示的区域，确定设备A在实际场景中所处的位置，使用户可以快速找到设备A.
例如，一种GUI如图16A和图16B所示，在确定设备A在图像中的区域之后，可以通过热力图的形式突出显示设备A在图像中的区域，图16A中所示为设备A未被遮挡的图像，其中，通过提示框的形式标记处了设备A所在的区域，图16B中所示为设备A被遮挡的热力图，通过热力图的方式标记出了被遮挡后的设备A所在的区域。此外，还可以通过提示框、文字、箭头等形式对设备A在图像中的区域进行突出显示，使用户可以直观地通过突出显示的区域确定设备A在实际场景中所处的位置。
613、判断设备B是否可移动，若否，则执行步骤614，若是，则执行步骤615。
其中，在确定设备A不在设备B的视野中时，可以继续判断设备B是否可移动，若可以移动，则可以指示移动设备B或者设备B自动移动等，即执行步骤615，若设备B不可移动，则可以直接显示位置指向图，即执行步骤614。
其中，步骤613为可选步骤，设备B可以直接获知自身是否可移动，例如，若设备B为智慧大屏、固定安装的监控器等，则设备B为不可移动设备，若设备B为手机、平板等不固定安装的设备，或者是扫地机器人、货运机器人等具有移动部件的设备，则设备B为可自动移动设备。当设备B为可移动设备时，可以直接提示朝向设备A移动或者自动朝向设备A移动，当设备B是不可移动时，即可直接显示位置指向图。
614、显示位置指向图。
本步骤614与前述步骤607类似，具体参阅前述步骤607中的相关介绍，此处不再赘述。
615、指示朝向设备A移动的方向和距离。
在确定设备B可移动之后，可以在显示屏中显示朝向设备A移动的方向和距离，以使用户可以根据显示屏中显示的内容朝向设备A移动设备B。
例如，一种GUI如图17所示，可以在显示屏中提示“朝右5米”，以使设备A在设备B的视野范围内。
在一些可能的场景中，设备B可以自动移动，在确定设备A不在设备B的视野内时，可以基于设备A和设备B的方向和距离，自动移动设备B，使设备A可以包括于设备B的视野范围内。
例如，一种GUI如图18A，设备B可以是带显示屏的扫地机器人，用户可以通过语音、触摸屏或者按键等指示扫地机器人搜寻无线耳机，扫地机器人在获取到无线耳机的位置信息之后，计算无线耳机相对于扫地机器人的方向和距离，判断该无线耳机是否在扫地机器人的视野内，若该无线耳机不在扫地机器人的视野内，且在扫地机器人的右侧，则此时扫地机器人可以向右移动，以使该无线耳机在扫地机器人的视野范围内，如图18B所示。
616、实时更新相对位置。
在设备B朝向设备A移动的过程中，若设备B检测到自身移动，则可以实时更新自身的位置，并实时计算设备A相对于设备B的位置，可能地，还可以在显示屏中显示该相对位置的变化。
例如，一种GUI如图19和图20所示，设备B可以是平板，在图19中，可以提示用户手持平板朝右移动3米，在移动过程中，如向右移动了2米之后，如图20所示，在平板的显示屏中显示朝右移动3米，以使待搜索的设备在平板的视野内。
因此，在本申请实施方式中，可以在设备B中对设备A与设备B的相对位置进行提示，使用户可以根据该相对位置快速找到设备A，提高用户体验。设备B具备拍摄功能和显示功能的情况下，可以在设备B的显示界面中突出显示设备A在图像中的区域，使用户可以通过图像中突出显示的内容，直观地观察到设备A实际所处的位置，从而快速搜寻到设备A。
