背景技术
随着社会的不断发展，增强现实(augmented reality，AR)装置也应用到生活的方方面面，AR装置的工作原理是通过处理器分析，将虚拟物体投射或显示在AR装置上，通过这样的方式，可以在用户观看现实世界场景的同时，为用户显示虚拟图像。用户还可以与虚拟图像进行交互来实现增强现实的效果。
但是，AR装置工作时需要使用高精度的摄像头等空间传感器，高性能处理器对大量图像数据进行实时处理，这导致AR装置功耗很大。而目前AR装置供电主要包括有线供电和电池供电。
通过有线供电的方式会导致AR装置只能在很小的空间范围内使用，大大限制了AR装置的使用场景，通过电池供电的方式，一般情况下续航很短，为了尽可能增大续航时间，会降低空间感知芯片精度，降低采样率等，这就导致用户看到的虚拟图像与真实场景贴合性、视野等不够好，沉浸感不强，用户体验不好；为了增加AR装置的续航，就需要增加电池容量，增加电池容量会导致设备变重，佩戴舒适性下降，因此如何在不降低用户体验的前提下，降低AR装置的功耗，延长AR装置的续航能力是本领域人员正在解决的技术问题。

具体实施方式
下面结合本申请实施例中的附图对本申请实施例进行描述。本申请实施例的实施方式部分使用的术语仅用于对本申请的具体实施例进行解释，而非旨在限定本申请。
下面介绍本申请实施例中涉及的几个概念：
(1)虚拟现实功能的启动和关闭：
本申请实施例中，电子设备为一种具有AR功能的AR装置。电子设备可以通过启动AR 功能实现对AR场景中数据的处理并显示AR画面。
可以理解的是，电子设备在启动AR功能时的功耗较大，在AR功能未启动或AR关闭功能时功耗较小。
示例性的，当电子设备中AR功能关闭时，电子设备中的协处理器、定位传感器工作。
协处理器：用于减轻应用处理器(application processor，AP)的处理负担，帮助AP执行部分工作的辅助处理器，协处理器的功耗一般小于AP的功耗。协处理器可以是把中央处理器(central processing unit，CPU)的频率与规格做适当的缩减，并将计数器、内存和显示驱动等相关模块都整合在单一芯片上，形成芯片级的控制单元。例如，协处理器中的一种可以为通用智能传感集线器(sensorhub)，sensorhub的主要功能是连接并处理来自各种传感器的数据，sensorhub的协处理器芯片的功耗仅为应用处理器芯片的功耗的1％-5％。
当电子设备中的AR功能启动时，电子设备中的控制器控制摄像头、图像信号处理器(image signal processor，ISP)或者图形处理器(graphics processing unit，GPU)工作。
具体的，在本申请的一些实施例中，定位传感器与协处理器、协处理器与控制器如何进行交互，从而确定摄像头、ISP或者GPU是否工作可通过如下两种方式实现：
第一种方式：
当定位传感器检测到定位标签，定位传感器向协处理器发送第一指示信号，该第一指示信号用于指示该定位传感器检测到定位标签，相应的，协处理器在接收到第一指示信号之后，将AR功能启停标志位的值置为1；当定位传感器未检测到定位标签，定位传感器向协处理器发送第二指示信号，该第二指示信号用于指示该定位传感器未检测到定位标签，相应的，协处理器在接收到第二指示信号之后，将AR功能启停标志位的值置为0。
控制器通过检测协处理器中AR功能启停标志位的值为1，控制摄像头、ISP或者GPU工作；控制器通过检测AR功能启停标志位的值为0，控制摄像头、ISP或者GPU不工作。
第二种方式：
当定位传感器从未检测到定位标签到检测到定位标签、或者从检测到定位标签到未检测到定位标签时，定位传感器向协处理器发送第三指示信号，该第三指示信号用于指示AR功能启停标志位的值发生改变，例如，定位传感器在第5秒时未检测到定位标签时，协处理器中的AR功能启停标志位的值为0，当定位传感器在第10秒时检测到定位标签时，确定AR功能启停标志位的值发生改变，则在第10秒时定位传感器向协处理器发送第三指示信号，该第三指示信号用于指示AR功能启停标志位的值发生改变，相应的，协处理器在接收到第三指示信号之后，将AR功能启停标志位的值为由0修改为1。
控制器通过检测协处理器中AR功能启停标志位的值为1，控制摄像头、ISP或者GPU工作；或者控制器通过检测协处理器中AR功能启停标志位的值由0修改为1，控制摄像头、ISP或者GPU工作。
在上述描述中，示例性的，AR功能启停标志位的值为0，1，也就是说，当定位传感器检测到定位标签时，AR功能启停标志位的值为1；当定位传感器未检测到定位标签时，AR功能启停标志位的值为0；当然AR功能启停标志位的值也可以为用其他不同值分别表示启动或关闭AR功能，本申请实施例不做限定。
(2)定位传感器和定位标签：
本申请实施例中，定位传感器用于探测定位标签，并且可以确定定位标签的位置；定位标签用于标识增强现实场景的位置。
定位传感器的探测范围：
由于用户视觉范围是由人眼视觉模型计算确定，因此用户视觉范围是确定的。在一个确定的用户视觉范围下，定位传感器位置不同，为了覆盖用户视觉范围，其探测范围会变大。在一种示例中，如图1所示，根据人眼视觉模型确定用户双眼的视觉范围为188度、2米，当定位传感器安装在电子设备500上两个显示屏中间的位置时，由于探测范围大于等于用于视觉范围，则探测范围为190度、2.2米。在又一种示例中，如图2所示，根据人眼视觉模型确定用户双眼的视觉范围为188度、2米，当定位传感器安装在电子设备500上右侧显示屏中间的位置时，由于探测范围大于等于用于视觉范围，则探测范围为200度、2.5米。在又一种示例中，根据人眼视觉模型确定用户双眼的视觉范围为188度、2米，当定位传感器安装在电子设备500上左侧显示屏中间的位置时，由于探测范围大于等于用于视觉范围，则探测范围为200度、2.5米。
在本申请实施例中，定位传感器的探测方向在所述电子设备中摄像头的前方。
可选的，在本申请的一些实施例中，当定位传感器为超宽带(ultra wide band，UWB)传感器时，定位标签为UWB标签；当定位传感器为具有蓝牙定位功能的传感器时，定位标签为蓝牙标签；当定位传感器为具有近场通信(near field communication，NFC)功能的传感器时，定位标签为NFC标签；当定位传感器为具有射频识别(radio frequency identification，RFID)功能的传感器时，定位标签为RFID标签。
目前，现有技术当中电子设备的结构和工作原理如下：如图3所示，图3表示一种电子设备的结构示意图，该电子设备包括处理器、摄像头、显示屏、以及图像信号处理器(image signal processor，ISP)或者图形处理器(graphics processing unit，GPU)，其中，处理器、ISP和GPU未在图1中画出。该显示屏可以为一个透镜，用户可以通过显示屏看到现实世界中的图像。
以博物馆场景为例，博物馆中包括展品1和展品2，其中，展品1中包括一个增强现实场景的位置信息，展品2中不包括增强现实场景的位置信息。如图4所示，当用户从展品1移动到展品2，也就是说电子设备从检测到增强现实场景的位置到未检测到增强现实场景的位置时，电子设备中AR功能一直处于启动工作状态。如图5所示，当用户一直观看展品1时，电子设备中AR功能处于启动工作状态，能对展品1的增强现实场景进行处理；如图6所示，当用户一直观看展品2，展品2上没有增强现实场景，不需要对增强现实场景进行处理，电子设备中AR功能也处于启动工作状态。
通过对现有技术电子设备开机到显示虚拟现实图像的过程分析，目前，电子设备开机之后，AR功能一直处于启动状态，处理器、摄像头、显示屏、以及ISP或者GPU等需要一直持续工作，功耗比较高，耗电量比较大。
为了解决以上问题，本申请实施例提出了一种增强现实功能控制方法和电子设备。示例性的，如图7所示，该电子设备可以包括处理器、摄像头、定位传感器、显示屏、以及ISP或者GPU，其中，处理器、ISP和GPU未在图4中画出。
以博物馆场景为例，博物馆中包括展品1和展品2，其中，展品1中包括定位标签，展品2中不包括定位标签。如图8所示，当用户从展品1移动到展品2，也就是说电子设备从检测到定位标签到未检测到定位标签时，电子设备中AR功能是否启动工作如图9和图10所示。如图9所示，当用户一直观看展品1，也就是电子设备检测到定位标签时，电子设备中AR功能处于启动工作状态；如图10所示，当用户一直观看展品2，也就是电子设备未检测到定位标签时，电子设备中AR功能处于关闭状态。
由于在未检测到定位标签时，高功耗器件不工作，因此，采用本申请实施例增强现实功 能控制方式能够降低功耗。
本申请实施例中电子设备可以为具有AR功能的手持式电子设备、头戴电子设备等，此处不作限定。
示例性的，用户可以佩戴头戴电子设备实现虚拟现实(virtual reality，VR)、AR、混合现实(mixed reality，MR)等不同效果。例如，头戴电子设备可以是眼镜、护目镜等。当头戴电子设备安装在用户头上时，用户眼睛可以看到头戴电子设备显示屏呈现的图像。

I2S接口可以用于音频通信。在一些实施例中，处理器110可以包含多组I2S总线。处理 器110可以通过I2S总线与音频模块170耦合，实现处理器110与音频模块170之间的通信。在一些实施例中，音频模块170可以通过I2S接口向无线通信模块160传递音频信号，实现通过蓝牙耳机接听电话的功能。
