具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述。
以下实施例中所使用的术语只是为了描述特定实施例的目的，而并非旨在作为对本申请的限制。如在本申请的说明书和所附权利要求书中所使用的那样，单数表达形式“一个”、“一种”、“所述”、“上述”、“该”和“这一”旨在也包括例如“一个或多个”这种表达形式，除非其上下文中明确地有相反指示。还应当理解，在本申请实施例中，“一个或多个”是指一个或两个以上(包含两个)；“和/或”，描述关联对象的关联关系，表示可以存在三种关系；例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B的情况，其中A、B可以是单数或者复数。字符“/”一般表示前后关联对象是一种“或”的关系。
在本说明书中描述的参考“一个实施例”或“一些实施例”等意味着在本申请的一个或多个实施例中包括结合该实施例描述的特定特征、结构或特点。由此，在本说明书中的不同之处出现的语句“在一个实施例中”、“在一些实施例中”、“在其他一些实施例中”、“在另外一些实施例中”等不是必然都参考相同的实施例，而是意味着“一个或多个但不是所有的实施例”，除非是以其他方式另外特别强调。术语“包括”、“包含”、“具有”及它们的变形都意味着“包括但不限于”，除非是以其他方式另外特别强调。
本申请实施例涉及的多个，是指大于或等于两个。需要说明的是，在本申请实施例的描述中，“第一”、“第二”等词汇，仅用于区分描述的目的，而不能理解为指示或暗示相对重要性，也不能理解为指示或暗示顺序。
随着电子设备的智能化程度提高，增强现实(augmented reality，AR)类型的应用越来越广泛。具有显示屏和摄像头的电子设备，有些固定安装在墙上、车上等，有些由于显示屏的尺寸较大(比如，显示屏尺寸在14英寸以上)，有些是上述两者兼具。即使该电子设备安装AR测量应用，或者集成AR测量功能，由于该电子设备或该电子设备上的摄像头不易转动甚至不能转动(比如，有些电子设备上的摄像头只能升降)，进而使得电子设备的AR测量应用或AR测量功能无法准确识别出基准测量平面，进而使得电子设备的AR测量结果的准确率低，用户体验较差。
移动设备由于其易于转动，通过ToF(time of flight)摄像头和AR测量应用或集成的AR测量功能，可以准确地识别出基准测量平面。
示例性地，图1为本申请实施例提供的移动设备测量时的用户界面示意图。在用户利用移动设备(以华为mate系列智能手机为例)上的AR测量待测量对象的长度时， 用户首先打开“实用工具”，选择“实用工具”中的“AR测量”，在“AR测量”中选择“长度”之后，移动设备将自动打开摄像头；用户将摄像头对准待测量对象所基于的基准测量平面(例如地面)，缓缓移动智能手机寻找平面，直到智能手机的显示屏显示如图1中的a所示的指示标(中间有个点的圆形)；用户缓缓移动智能手机，使得待测量对象的一端位于指示标处，如图1中的b所示，用户点击“添加起始点”图标确定测量起始点；用户缓缓移动智能手机，如图1中的c所示，在指示标移动至待测量对象的另一端的过程中，智能手机上便会显示待测量对象的长度；在指示标移动至待测量对象的另一端时，此时显示的长度即为待测量对象的长度。
这样，用户可以测量人的身高。有关操作如下：首先打开“实用工具”，选择“实用工具”中的“AR测量”，在“AR测量”中选择“长度”之后，智能手机将自动打开摄像头；用户将摄像头对准人脚下平面，缓缓移动智能手机定位平面，直到显示屏出现指示标(中间有个点的圆形)；用户缓缓移动智能手机，使得人脚位于指示标处；用户点击“添加起始点”图标固定测量起始点；缓缓向上移动智能手机，当指示标移动至人的头顶后，智能手机显示的长度即为人的身高。
发明人经过研究，总结出：具有摄像头和显示屏的电子设备，由于固定安装或显示屏尺寸较大的原因，不易转动甚至不能转动，即使为该电子设备配置有ToF(time of flight)摄像头，也无法准确地识别出基准测量平面，仍然无法解决测量不准确的问题；考虑到移动设备或移动设备上的ToF(time of flight)摄像头易于转动，可以通过上述电子设备和上述移动设备的配合，解决上述技术问题，从而提高用户体验。
有鉴于此，本申请提供了一种测量长度的方法、电子设备以及移动设备。电子设备和移动设备无线通信。可选地，两者可在同一局域网中。在本申请提供的方法中，先利用移动设备的摄像头扫描并建立好电子设备周围环境的第一三维点云图(电子设备周围环境包括待测量对象基于的基准测量平面)，并确定第一三维点云图中的基准测量平面，移动设备将第一三维点云图以及基准测量平面在第一三维点云图中的位置，发送给电子设备(例如，华为智慧屏)。在电子设备自行扫描或自行拍摄待测量对象和待测量对象所基于的平面的图像后，电子设备基于第一三维点云图、第一三维点云图中的基准测量平面，以及上述自行扫描或自行拍摄的图像，可以确定自行扫描或自行拍摄的图像中的基准测量平面，从而在电子设备自行扫描或自行拍摄的图像中确定待测量对象的基准测量平面；电子设备从自行扫描或自行拍摄的图像中，确定待测量对象与基准测量平面的接触端为待测量对象的一端；电子设备自动识别出待测量对象的另一端；并给出待测量对象的两端之间的长度。这样，电子设备可以准确地测量出待测量对象的长度。这样，即使具有显示屏和摄像头的电子设备，固定安装在墙上、车上等，或者显示屏的尺寸较大(比如，显示屏尺寸在14英寸以上)，也能通过电子设备安装的AR测量应用或集成的AR测量功能，准确地进行AR测量。用户体验也得以改善。
示例性地，图2为本申请实施例提供的测量长度的方法的场景示意图。如图2所示，移动设备100与电子设备200无线通信。无线通信的方式，包括但不限于以下的至少一种：蓝牙、Wi-Fi等。其中，Wi-Fi的无线通信方式可以为Wi-Fi P2P(peer to peer)，也可以为同一局域网下的Wi-Fi连接。移动设备100包括ToF(time of flight)摄像头 110、显示屏120，并且移动设备100安装有AR测量类的应用程序，或者集成有AR测量的功能。摄像头110包括ToF(time of flight)摄像头。电子设备200包括摄像头220、显示屏210，并且电子设备200也安装有AR测量类的应用程序，或者集成有AR测量的功能。
示例性地，摄像头220可以安装在电子设备的显示屏210的上边缘。电子设备200和移动设备100位于同一个区域(比如，同一房间)内。可选地，电子设备200的摄像头220和移动设备100上的摄像头110均为ToF(time of flight)摄像头；或者，电子设备200上的摄像头也可以为其他的摄像头，而不是ToF(time of flight)摄像头。
应理解，在本申请实施例中，对于摄像头220在显示屏210上的位置不作限制。例如，摄像头220还可以安装在显示屏210的左边缘或者右边缘等位置。
虽然在图2中电子设备200是以具有摄像头和较大显示屏的电子设备为例，但本领域技术人员熟知的是，电子设备200也可以是固定安装的电子设备，比如车载电脑等。电子设备200可以搭载
Figure PCTCN2022079102-appb-000001
Windows、Linux或者其它操作系统。电子设备200安装AR测量类的APP，或者集成AR测量功能。示例性地，电子设备200包括但不限于智能电视、台式计算机、车载设备等。本申请实施例对此不作限定。电子设备200包括一个摄像头。示例性地，该摄像头不易转动或不能转动。示例性地，上述电子设备不易转动或不能转动。
示例性地，移动设备100包括摄像头。移动设备100安装有AR测量类的APP，或集成有AR测量功能。示例性地，移动设备100包括但不限于以下的一种：智能手机、智能耳机、平板电脑、具备无线通讯功能的可穿戴电子设备(如智能手表、智能手环、智能戒指、智能眼镜)、膝上型计算机(Laptop)等。移动设备的示例性实施例包括但不限于搭载
Figure PCTCN2022079102-appb-000002
Windows、Linux或者其它操作系统的便携式电子设备。
移动设备200和电子设备100安装的AR测量类APP可以为相同的APP，或者，也可以是不同的AR测量类APP。可选地，移动设备或电子设备的AR测量类APP或AR测量功能，可以为移动设备或电子设备出厂时就预装在设备上，或出厂时就集成在设备上的。
示例性地，图3为本申请实施例提供的测量长度的方法的流程示意图。图3所示的方法可以应用在图2所示的场景中。因为移动设备易于转动和移动，所以移动设备上的摄像头不限于能否升降，也不限于能否转动。移动设备与电子设备无线通信。无线通信的方式包括但不限于Wi-Fi，蓝牙，ZigBee等。如图3所示，该方法300包括：
S301，电子设备向移动设备发送请求消息，请求消息用于请求获取电子设备周围环境的第一三维点云图。
可选地，用户在电子设备第一次开机初始化的过程中，便触发了电子设备向移动设备发送请求消息；请求消息用于请求获取电子设备周围环境的三维点云图(以下为了便于区分，称为第一三维点云图)。在该过程中，用户仅需打开电子设备即可。
可选地，在用户将电子设备从一个房间换到另一个房间后，由于电子设备所在的周围环境发生变化，用户可以打开电子设备的AR测量类应用，此时便触发了电子设备向移动空设备发送请求消息，请求消息用于请求获取电子设备周围环境的第一三维 点云图。
可选地，在用户需要利用电子设备测量人的身高时，用户点击打开电子设备上的AR测量类型的应用，此时便触发了电子设备向移动设备发送请求消息，请求消息用于请求获取电子设备周围环境的第一三维点云图。
S302，移动设备接收到该请求消息后，根据用户输入，确定是否获取电子设备周围环境的第一三维点云图。
具体地，在移动设备接收到该请求消息后，移动设备可以在显示界面上提示用户：是否获取电子设备周围环境的第一三维点云图。用户可以点击“是”选项，表明用户同意。用户也可以点击“否”选项，表明用户拒绝。上述的“是”选项可以替换为“同意”选项等其他含义相同或相近的选项。上述的“否”选项可以替换为“拒绝”选项等其他含义相同或相近的选项。
在用户点击“是”选项后，移动设备可以执行S303。可选地，在执行S303之前，移动设备还可以向电子设备发送响应消息；响应消息用于指示移动设备同意获取电子设备的周围环境的第一三维点云图。可选地，移动设备也可以不向电子设备发送响应消息。
如果用户不同意，则用户可以点击“否”选项。可选地，用户点击“否”选项后，移动设备也可以向电子设备发送响应消息；响应消息用于指示移动设备不同意获取电子设备的周围环境的第一三维点云图。可选地，移动设备也可以不向电子设备发送响应消息。
S303，在用户输入指示同意后，移动设备通过摄像头扫描，获取电子设备周围环境的第一三维点云图。
在用户输入指示同意的情况下，移动设备显示扫描界面。用户可以拿起移动设备左右移动，利用移动设备的ToF摄像头扫描电子设备的周围环境。扫描结束后，移动设备会生成电子设备的周围环境的第一三维点云图。
可选地，用户输入可以为触摸输入，也可以为语音输入。
可选地，电子设备的周围环境包括待测量对象基于的基准测量平面。进一步地，电子设备的周围环境还可包括待测量对象。相应地，第一三维点云图包括待测量对象基于的基准测量平面、待测量对象的图像。进一步地，第一三维点云图还可包括电子设备的图像。
点云图是指通过测量仪器(例如3D摄像头、激光扫描仪等)对对象进行拍照或者扫描，从而得到的对象外观表面的点数据的集合。例如，在上述用户利用移动设备测量身高的过程中，用户利用移动设备上的ToF摄像头进行扫描或拍摄获得图像，移动设备便可以根据该图像，生成该图像对应的三维点云图。
具体地，ToF摄像头可以通过红外光以及飞行时间原理，主动发射红外光并接收返回的红外光，从而可以测出周围环境中各对象与摄像头之间的距离。因此，ToF摄像头可以直接扫描或拍摄各对象的图像，并且可以测量各对象与摄像头距离，从而在拍摄的图像上恢复出被扫描或被拍摄的各对象的三维结构。
移动设备可以通过ToF摄像头，对电子设备的周围环境扫描。电子设备的周围环境包括待测量对象基于的基准测量平面，进一步的，还可以包括待测量对象和电子设 备。可选的，电子设备的周围环境还可包括其他的对象等。本申请对此不作限定。可选地，在扫描中，移动设备可以左右来回移动。在扫描后，移动设备可以利用视觉同时定位与地图构建(simultaneous localization and mapping，SLAM)技术获取第一三维点云图。第一三维点云图可以准确地反映各对象的三维形状，并且第一三维点云图中每个点的空间坐标都是确定的。
用户在利用移动设备扫描电子设备周围环境的过程中，需要缓缓移动或者转动移动设备，以识别基准测量平面。这样，就可以在第一三维点云图中确定出基准测量平面。以测量人的身高为例，基准测量平面为人站立的平面。比如，地面等。
可选的，在本申请实施例中，也可以不用执行S301，这样，移动设备也可以不用执行S302和S303。取而代之的为：移移动设备通过摄像头扫描，获取电子设备周围环境的第一三维点云图。该步骤可以是用户在移动设备上周期性设置启动的，例如，每半年启动依次，或者，是用户根据自己的需要，对移动设备进行相应的操作进而启动的。之后可以执行S304。
S304，移动设备将第一三维点云图发送给电子设备。
示例性地，移动设备可以通过之前建立的无线通信方式向电子设备发送第一三维点云图。比如，移动设备与电子设备之前建立Wi-Fi直连，此时移动设备通过Wi-Fi直连向电子设备分享第一三维点云图。
电子设备接收到第一三维点云图后，执行S305。
应理解，上述的S301、S302、S303和S304可以是在电子设备初始化的时候执行。例如，在用户安装好电子设备且第一次开机后，移动设备可以将电子设备的周围环境的第一三维点云图发送给电子设备。也就是说，S301、S302、S303和S304可以只执行一次。在电子设备的周围环境变化的情况下，可以重新执行S301、S302、S303和S304。例如，用户将电子设备从一个房间换到了另一个房间后，可以重新执行S303和S304。
S305，利用自身摄像头自行扫描或自行拍摄图像，自行扫描或自行拍摄的图像包括待测量对象和待测量对象基于的平面。
可替换地，自行扫描或自行拍摄的图像包括待测量对象的另一端和待测量对象的一端基于的平面。
可选地，在待测量对象为人，要给人测量身高的场景下，假设人站在地面上，自行扫描或自行拍摄的图像可以仅包括人的头部或脸部，以及地面。这时，自行扫描或自行拍摄的图像可以不包括人的脚部。这是基于人一定站在地面的假设前提下。
可选地，电子设备的摄像头可以为ToF摄像头，也可以不为ToF摄像头。
可选地，在电子设备的摄像头为ToF摄像头的前提下，电子设备可以根据自行扫描或自行拍摄的图像，生成第二三维点云图。
可选地，自行扫描或自行拍摄的图像可以包括待测量对象的全部图像。比如，待测量对象为人，自行扫描或自行拍摄的图像可以包括人的全部图像(即全身照)。
S306，电子设备根据自行扫描或自行拍摄的图像、第一三维点云图，确定待测量对象在自行扫描或自行拍摄的图像中的基准测量平面。
由于电子设备不易转动或不能转动，或者，电子设备的摄像头不易转动或不能转 动，所以自行扫描或自行拍摄的图像中信息有限，电子设备不能仅从自行扫描或自行拍摄的图像中，确定出基准测量平面。不过，由于第一三维点云图包括待测量对象基于的基准测量平面，因此电子设备可以基于第一三维点云图中的基准测量平面，确定出自行扫描或自行拍摄的图像中的基准测量平面。
进一步地，电子设备可以在自行扫描或自行拍摄的图像中，确定出待测量对象的一端与基准测量平面的交点(即测量起点)。
可选地，在电子设备根据自行扫描或自行拍摄的图像，生成第二三维点云图后，由于电子设备不易转动或不能转动，或者，电子设备的摄像头不易转动或不能转动，所以自行扫描或自行拍摄的图像中信息有限，因而第二三维点云图中的信息有限，电子设备不能仅从第二三维点云图中，确定出基准测量平面。不过，由于第一三维点云图包括待测量对象基于的基准测量平面，因此电子设备可以基于第一三维点云图中的基准测量平面，确定出第二三维点云图中的基准测量平面。
在一种示例中，第一三维点云图可以理解为一个全集。第二三维点云图可以理解为第一三维点云图这一全集中的一个子集。电子设备将第一三维点云图和第二三维点云图进行融合和匹配，根据第一三维点云图中的基准测量平面，确定第二三维点云图中的基准测量平面。
在一种示例中，由于第二三维点云图有一个平面与第一三维点云图中的基准测量平面具有相同的属性，电子设备可以据此识别出第二三维点云图中的基准测量平面。
进一步地，电子设备可以在第二三维点云图的基准测量平面中识别出测量起点。
在一种示例中，以测量人的身高为例，图4示出了电子设备测量人的身高的用户界面。如图4所示，指示标所在的位置即为测量起点。
进一步地，电子设备可以在第二三维点云图中，确定出待测量对象的一端与基准测量平面的交点(即测量起点)。
可选地，在假设待测量对象一定站立在基准测量平面的前提下，也可不用确定出待测量对象的一端与基准测量平面的交点。
可选地，基准测量平面可以为地平面。地平面可以为一楼的地平面、二楼的地平面、三楼的地平面等任意楼层的地平面。
S307，电子设备自动获取待测量对象的测量终点，根据自行扫描或自行拍摄图像中的测量基准平面和测量终点，确定待测量对象的长度。
可选地，自行扫描或自行拍摄的图像可以包括待测量对象的测量终点。电子设备从自行扫描或自行拍摄的图像中获取待测量对象的测量终点。
可选地，第二三维点云图可以包括待测量对象的测量终点。电子设备从第二三维点云图中获取待测量对象的测量终点。
在一种示例中，待测量对象为人，测量终点为人的头顶位置或人的眼睛位置。
若上述的测量终点为人的头顶位置，可以从自行扫描或自行拍摄的图像中，根据测量起点和测量终点，使用AR测量，获取到待测量对象的高度。
若上述的测量终点为人的眼睛位置，可根据统计得到的人眼到头顶的平均距离，估算待测量人的身高。具体地，统计得到的人眼到头顶的平均距离一般在10cm-12cm之间。在本申请实施例中，人眼到头顶的平均距离可以取10cm、11cm或者12cm。将 人眼到头顶的平均距离加上基准测量平面到人眼之间的距离，便可以得到待测量人的身高。电子设备便可以显示人的身高。可替换地，电子设备也可以通过语音播放人的身高。
可替换地，电子设备自动获取待测量对象的测量终点，根据第二三维点云图中的测量基准平面和测量终点，确定待测量对象的长度。
在一种示例中，待测量对象为人，测量终点为人的头顶位置或人的眼睛位置。
若上述的测量终点为人的头顶位置，可以从第二三维点云图中，根据测量起点和测量终点，使用AR测量，获取到待测量对象的高度。
若上述的测量终点为人的眼睛位置，可根据统计得到的人眼到头顶的平均距离，估算待测量人的身高。具体地，统计得到的人眼到头顶的平均距离一般在10cm-12cm之间。在本申请实施例中，人眼到头顶的平均距离可以取10cm、11cm或者12cm。将人眼到头顶的平均距离加上基准测量平面到人眼之间的距离，便可以得到待测量人的身高。电子设备便可以显示人的身高。可替换地，电子设备也可以通过语音播放人的身高。
应理解，在本申请实施例中，对于人眼到头顶的平均距离的取值也可以为其他值，本申请实施例在此不作限制。
可选地，电子设备可以通过自行扫描或自行拍摄的图像，自行决定测量终点为人的头顶位置或人的眼睛位置。具体来说，若人距离电子设较近，电子设备未能扫描或拍摄到人的头顶，但扫描或拍摄到人的眼睛，则以人的眼睛位置为测量终点。若人距离电子设备较远，电子设备扫描或拍摄到人的头顶，则以人的头顶位置为测量终点。若电子设备未能扫描或拍摄到人，在一种方式下，电子设备可以提醒人调整其与电子设备的摄像头之间的距离，直至电子设备能够扫描或拍摄到人的头顶或人的眼睛；在另一种方式下，电子设备可以升降自身摄像头，寻找人的头顶或人的眼睛，若在预设时长内寻找到，则按照上述的方式处理；若在预设时长内未能寻找到，则电子设备可以提醒人调整其与电子设备的摄像头之间的距离，直至电子设备能够扫描或拍摄到人的头顶或人的眼睛。若电子设备扫描或拍摄到人的头顶和眼睛，可以优选人的头顶位置为测量终点，也可以优选人的眼睛位置为测量终点。
以上仅是以测量人的身高为例说明。本领域技术人员应当明了，测量其他对象的长度、高度、宽度、厚度等与此类似。此处不再一一说明。
需要说明的是，S301-S304并不是每次都要执行的，仅在起始执行一次即可。后续，只要电子设备所处空间的基准测量平面(比如，地平面)没有变化，就无需执行。比如，电子设备固定在客厅的墙上，在执行过一次S301-S304之后，电子设备仍然固定在客厅的墙上，只要客厅的地平面没有变化，下次就无需再次执行S301-S304，直接执行S305-S307即可。
若电子设备被移动至其他房间，或者基准测量平面发生变化(比如，地平面上铺了地毯等)，则需要重新执行S301-S304。
可替换地，S303也可被替换为：接收到一个用户输入后，移动设备获取电子设备周围环境的第一三维点云图；之后执行S304-S307。此时，在S304之前，就无需执行S301-S303了。即在本实施方式提供的替换后的方法中不包括S301-S303，仅包括替换 后的S304以及图3示出的S305-S307。同样地，替换后的S303并非每次都需要执行。仅在起始执行一次即可。后续，只要电子设备所处空间的基准测量平面(比如，地平面)没有变化，就无需执行。
可选地，在电子设备获取到待测量对象的长度后，电子设备还可以将待测量对象的长度等信息(比如，当前时间、自行扫描或自行拍摄的图像等中的至少一项)发送给移动设备或其他的远程设备。其他的远程设备与电子设备可以预先绑定。这样，通过其他的远程设备也可以查看或存储上述信息。其他的远程设备可以为服务器，也可以为智能设备。
