具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
参见图1，图1是本公开实施例提供的对象识别方法的流程图，如图1所示，包括以下步骤：
步骤101、当所述移动终端处于熄屏状态时，通过处于第一运行状态的所述摄像头采集扫描对象，得到第一采集结果。
其中，熄屏状态可以理解为移动终端处于运行状态，且屏幕不显示信息时的状态。例如，将移动终端锁屏后，移动终端屏幕不显示信息时的状态。在此步骤中，移动终端处于熄屏状态时，摄像头处于开启状态并在第一运行状态下运行。
上述第一运行状态可以是摄像头的运行功率小于预设功率值的状态，例如，运行功率小于50毫瓦、60毫瓦或者100毫瓦等的低功耗运行状态。这 样，用户可以操纵移动终端控制摄像头在第一运行状态下常开，或者移动终端在开机时自动开启摄像头并使其在第一运行状态下运行，即在移动终端亮屏或熄屏时均开启，便于用户随时使用摄像头采集扫描对象。在具体实施时，也可以控制摄像头仅在熄屏状态下开启，而在亮屏状态时关闭，可以进一步节约功耗。另外，第一运行状态还可以是像素小于预设像素值的状态，由于第一运行状态下的像素较低，可以降低摄像头的功耗。
可选地，所述第一运行状态为开启所述摄像头的部分像素单元的状态，所述第二运行状态为开启所述摄像头的全部像素单元的状态。
在该实施方式中，移动终端可以利用已有的摄像头，在第一运行状态下控制该摄像头的部分像素单元处于常开状态，即，在移动终端为熄屏和亮屏的情况下，均处于开启状态，其中，一个像素单元可以对应一个像素。
例如，在1200万像素的摄像头中，在第一运行状态下，均匀选取30万像素工作，而其余像素不工作；又如，将5M的摄像头，开启160×120这样低分辨率的低功耗模式，从而控制该摄像头在第一运行状态下运行。
摄像头在仅部分像素单元工作时的功率小于预设功率值，摄像头可以利用开启的部分像素单元随时采集扫描对象，可以节约功耗，且可以利用已有的摄像头，而不需要再单独设置低功耗摄像头。
其中，当摄像头处于第一运行状态时，移动终端可以是处于亮屏或者熄屏的状态，这样，摄像头可以随时采集扫描对象，而不需要用户开启应用程序进行采集，用户操作便捷。
上述第二运行状态即将摄像头的全部像素单元开启，例如，在1200万像素的摄像头中，在第二运行状态下，控制所有像素单元全部工作，这样能够获得更加清晰的图像，能够提高识别率。
步骤102、当根据所述第一采集结果确定所述扫描对象符合预设条件时，控制所述摄像头进入第二运行状态，通过处于所述第二运行状态的所述摄像头采集所述扫描对象，得到第二采集结果，并根据所述第二采集结果对所述扫描对象进行识别，控制所述移动终端亮屏，显示所述扫描对象对应的识别结果；其中，所述摄像头在所述第二运行状态下的运行功率大于所述摄像头在所述第一运行状态下的运行功率。
在此步骤中，移动终端可以预先存储对扫描对象的辨识算法，例如，人脸算法、二维码识别算法、手势识别算法等，可选地，可以将对扫描对象的辨识算法存储在摄像头中。这样，在摄像头采集扫描对象后，摄像头可以根据第一采集结果，并结合扫描对象的特征初步判断扫描对象是否符合预设条件，从而在扫描对象符合预设条件的情况下，唤醒移动终端进一步对扫描对象进行采集和识别。
其中，预设条件可以是移动终端预先设置并存储的条件，符合预设条件可以理解为扫描对象为预设类型，预设类型可以包括二维码、手势和人脸等。这样，移动终端可以仅对符合预设条件的扫描对象进一步进行识别。例如，摄像头中集成二维码识别算法，在摄像头采集图像后，摄像头判断该图像中是否具有二维码的特征；又如，摄像头中集成人脸识别图像，在摄像头采集图像后，摄像头判断采集的图像中是否具有人脸图像的特征。
由于摄像头在第一运行状态下采集的图像的像素较低，这样，摄像头对扫描对象是否符合预设条件的判断可能会存在误差。因此，在判断扫描对象符合预设条件的情况下，摄像头进入第二运行状态，并通过处于第二运行状态下的摄像头采集扫描对象。由于第二运行状态下的运行功率高于第一运行状态下的运行功率，摄像头在第二运行状态下能够获得更加清晰的图像。移动终端基于摄像头在第二运行状态下采集的第二采集结果对扫描对象进行识别，一方面可以防止摄像头在第一运行状态下对扫描对象的误辨识；另一方面，可以更准确地识别扫描对象的具体内容。
由于摄像头在第一运行状态下的功率较低，通过第一运行状态下的摄像头对扫描对象进行采集和辨识，能够节约功耗。这样，对符合预设条件的扫描对象进一步采集，以防止对扫描对象的误识别，且能够更加准确地获取扫描对象的具体内容或进一步获取扫描对象的具体信息，即识别结果，从而在移动终端屏幕上显示该识别结果。例如，当摄像头识别扫描对象为二维码时，可以进一步识别二维码的具体内容为支付二维码，从而在屏幕上显示支付界面。
另外，在摄像头识别扫描对象不符合预设条件时，则不对扫描对象进行进一步识别，能够节约功耗。
为了便于理解本方案，以下进行举例说明。
移动终端具有后置摄像头，且后置摄像头中集成二维码的识别算法。移动终端的后置摄像头处于常开且低功耗运行状态，即第一运行状态，其中，低功耗运行状态为仅开启摄像头的部分像素单元，且运行功率低于预设功率值的状态。常开状态即摄像头在移动终端熄屏和亮屏均开启的状态。
当用户需要支付时，此时，移动终端可以处于亮屏或熄屏状态，用户可以将移动终端的后置摄像头对着支付二维码，由于后置摄像头处于低功耗状态下常开，后置摄像头采集包含二维码的图像，摄像头进一步判断该图像中是否包含二维码。在摄像头判断采集的图像中包含二维码的情况下，移动终端控制摄像头的全部像素单元均开启，摄像头进入第二运行状态。移动终端通过摄像头的全部像素单元采集二维码图像，并进一步识别二维码中的信息，并根据二维码中的信息在屏幕上显示支付界面。
这样，移动终端在扫描二维码的过程中，不需要通过用户进行交互操作扫码，支付快捷，通过第一运行状态下的摄像头对二维码进行采集和识别，能够减少功耗。
本公开实施例中，上述对象识别方法可以应用于具有摄像头的移动终端，例如：手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(personal digital assistant，PDA)、移动上网装置(Mobile Internet Device，MID)或可穿戴式设备(Wearable Device)等。
本公开实施例的对象识别方法，当所述移动终端处于熄屏状态时，通过处于第一运行状态的所述摄像头采集扫描对象，得到第一采集结果；当根据所述第一采集结果确定所述扫描对象符合预设条件时，控制所述摄像头进入第二运行状态，通过处于所述第二运行状态的所述摄像头采集所述扫描对象，得到第二采集结果，并根据所述第二采集结果对所述扫描对象进行识别，控制所述移动终端亮屏，显示所述扫描对象对应的识别结果；其中，所述摄像头在所述第二运行状态下的运行功率大于所述摄像头在所述第一运行状态下的运行功率。这样，移动终端可以控制摄像头在熄屏状态下处于第一运行状态，从而使摄像头可以随时采集扫描对象，而不需要用户手动开启应用程序，用户操作便捷，且能够提高扫描效率。且基于第二运行状态下的摄像头采集 的扫描对象进行识别，能够提高识别的精确度，减少误差。
参见图2，本实施例与上述实施例的主要区别在于，在处于第一运行状态下的摄像头判断扫描对象的特征与预设特征相匹配的情况下，通过第二运行状态下的摄像头采集扫描对象。
图2是本公开实施例提供的对象识别方法的流程图，如图2所示，包括以下步骤：
步骤201、当所述移动终端处于熄屏状态时，通过处于第一运行状态的所述摄像头采集扫描对象，得到第一采集结果。
其中，此步骤具体实现方式可以参见步骤101，为避免重复，此处不再赘述。
可选的，所述当所述移动终端处于熄屏状态时，通过处于第一运行状态的所述摄像头采集扫描对象之前，所述方法还包括：开启所述摄像头，控制所述摄像头进入所述第一运行状态。
在该实施方式中，用户可以通过对移动终端进行操作开启摄像头，也可以是移动终端在开启时自动开启摄像头。
移动终端可以设置摄像头在第一运行状态和第二运行状态的切换控件，用户可以对切换控件进行操作控制摄像头处于第一运行状态，用户可以根据应用场景和移动终端的状态灵活操作；移动终端也可以在开启时自动控制摄像头处于第一运行状态，以节约移动终端功耗，且便于用户操纵移动终端对扫描对象进行扫描。需要注意的是，该实施方式也可以应用于图1对应的实施例中，以及达到相同的有益效果。
可选的，所述开启所述摄像头，包括：当所述移动终端开机或熄屏时，开启所述摄像头。
在该实施方式中，移动终端可以在开机时即开启摄像头，并控制摄像头在熄屏和亮屏状态下均处于常开状态，这样便于用户随时使用移动终端的摄像头进行扫描。移动终端也可以在检测到移动终端熄屏时开启摄像头，而在亮屏时则关闭摄像头，能够节约功耗，且便于用户在移动终端处于熄屏状态下扫描。需要注意的是，该实施方式也可以应用于图1对应的实施例中，以及达到相同的有益效果。
可选的，在通过所述摄像头采集扫描对象之后，所述方法还包括：在通过所述摄像头判断出所述扫描对象符合预设条件的情况下，所述移动终端输出提示信息。
在该实施方式中，在摄像头识别扫描对象符合预设条件的情况下，移动终端输出提示信息，具体可以通过振动或者输出语音的方式提示。这样，当移动终端处于熄屏状态时，若识别扫描对象符合预设条件，输出提示信息，用户不需要调整摄像头的位置，且可以提示用户及时查看移动终端显示的信息。
需要注意的是，该实施方式也可以应用于图1对应的实施例中，以及达到相同的有益效果。
步骤202、通过所述摄像头根据所述第一采集结果识别所述扫描对象的特征。
其中，摄像头中可以集成对扫描对象的辨识算法，例如，人脸识别算法、手势识别算法以及二维码识别算法等等。摄像头采集到扫描对象后，可以根据第一采集结果识别扫描对象的特征。例如，二维码的特征可以包括轮廓特征，以及二维码的定位点的特征；人脸图像的特征可以包括五官特征及分布位置，等等。摄像头可以对扫描对象的特征进行识别，从而确定扫描对象是否为预设类型的扫描对象。
步骤203、在所述摄像头判断所述扫描对象的特征与预设特征相匹配的情况下，控制所述摄像头进入第二运行状态；其中，所述摄像头在所述第二运行状态下的运行功率大于所述摄像头在所述第一运行状态下的运行功率。
摄像头在识别扫描对象的特征后，可以将该特征与预设特征对比。若扫描对象的特征与预设特征的相似度大于预设相似度值，例如，大于80％，则表示扫描对象的特征与预设特征相匹配，即扫描对象符合预设条件，则移动终端控制摄像头进入第二运行状态。
这样，通过第一运行状态的摄像头对扫描对象进行初步识别，由于第一运行状态下的摄像头运行功率较低，能够减少移动终端的功耗，且用户操作便捷。
步骤204、通过处于所述第二运行状态的所述摄像头采集所述扫描对象， 得到第二采集结果，并根据所述第二采集结果对所述扫描对象进行识别，控制所述移动终端亮屏，显示所述扫描对象对应的识别结果。
此步骤的具体实现方式可以参见步骤102中的相关描述，此处不再赘述。
