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、在所述移动终端处于熄屏状态的情况下，通过处于第一运行状态的所述摄像头采集第一图像。
其中，所述摄像头在所述第一运行状态下的运行功率小于预设功率值。 预设功率值可以是移动终端预先设置或者移动终接收用户操作预先设置的值，摄像头在第一运行状态下的运行功率较低，能耗较小。例如，摄像头的运行功率小于50毫瓦、60毫瓦或者100毫瓦等的低功耗运行状态。
移动终端具体可以通过开启摄像头的部分像素单元的方式控制摄像头处于第一运行状态。例如，在1200万像素的摄像头中，均匀选取30万像素工作，而其余像素不工作，该工作状态为第一运行状态。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。
上述熄屏状态可以理解为移动终端正在运行，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。
在具体实施时，用户可以设置移动终端的摄像头在开机时自动开启，并处于第一运行状态下持续运行，便于用户随时使用摄像头采集扫描对象。也可以控制摄像头在熄屏状态下自动开启，即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。
步骤102、若所述第一图像具备目标对象类型的图像特征，控制所述摄像头进入第二运行状态，并通过处于所述第二运行状态的所述摄像头采集第二图像。
其中，所述摄像头在所述第二运行状态的运行功率高于在所述第一运行状态的运行功率。第二运行状态可以是开启摄像头的部分像素单元或者开启摄像头的全部像素单元的运行状态。在第二运行状态下开启的像素单元数量大于在第一运行状态下开启的像素单元的数量时，摄像头在第二运行状态下的运行功率高于在第一运行状态下的运行功率。例如，可以根据摄像头的运行功率，按照功率从低到高将摄像头设置多个档位。在通过最低功率对应档位的摄像头检测并识别到目标对象类型的图像时，可以将最低功率对应的档位切换到其他档位。
由于摄像头在第一运行状态下的功率较低，可以对第一运行状态下的摄像头采集的第一图像进行初步识别，判断第一图像是否具备目标对象类型的 图像特征。其中，目标对象类型可以是移动终端预先设置的具有特定特征的对象类型，包括人脸、二维码、手势等等。例如，二维码的图像特征包括具有三个“回”型定位点，人脸的图像特征包括五官分布位置及五官特征，手势的图像特征包括手势的形状特征等。若包含目标对象类型的图像特征，则摄像头由第一运行状态切换为第二运行状态。
以二维码为例，若识别到第一图像中具备二维码的图像特征，则摄像头由第一运行状态切换为第二运行状态，并再次对该二维码进行采集。由于第二运行状态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采集的第二图像的像素高于第一图像的像素，可以进一步基于第二图像对二维码的具体内容进行识别，可以减少对图像识别的误差。
步骤103、若识别所述第二图像中包含具备所述图像特征的不完整图像，则输出用于指示所述第二图像不完整的提示信息。
在此步骤中，移动终端对第二图像的特征进行识别，若识别到第二图像中包括具备上述目标对象类型的图像特征，且该图像为不完整的图像，则移动终端输出提示信息，以提示用于第二图像为不完整的图像。其中，对目标对象类型的图像特征的具体识别方式可以参见步骤102中的识别方式。对不完整的图像的判断可以基于目标对象类型的图像特征进行判断。例如，如图1-1所示的图像为不完整的二维码。二维码的完整图像包含三个“回”型定位点，若仅检测到两个“回”型定位点，该图像可以认为是不完整的二维码图像。例如，完整的人脸图像包括五官及脸部图像，若在图像中仅检测到眼睛和鼻子的图像，则该图像可以是不完整的人脸图像。提示信息可以通过在屏幕上显示不完整的图像或者输出语音、振动等方式提示。例如，在屏幕上显示如图1-1中的不完整图像，用户可以基于该图像将移动终端向右移动，以采集二维码的完整图像，从而可以提高对二维码的识别效率。
本公开实施例中，上述对象识别方法可以应用于移动终端，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，在所述移动终端处于熄屏状态的情况下， 通过处于第一运行状态的所述摄像头采集第一图像；若所述第一图像具备目标对象类型的图像特征，控制所述摄像头进入第二运行状态，并通过处于所述第二运行状态的所述摄像头采集第二图像；若识别所述第二图像中包含具备所述图像特征的不完整图像，则输出用于指示所述第二图像不完整的提示信息；其中，所述摄像头在所述第二运行状态的运行功率高于在所述第一运行状态的运行功率。这样，移动终端可以在熄屏状态下采集扫描对象，而不需要用户进行一系列交互操作启动扫码功能进行采集，可以提高扫码效率。且在识别到目标对象类型的不完整图像时，可以输出提示信息，以提示用户偏移移动终端从而采集完整图像，能够进一步提高对象识别效率。
参见图2，本实施例与上述实施例的主要区别在于，若第二图像中不包含具备上述图像特征的图像，则将摄像头由第二运行状态切换为第一运行状态。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、在所述移动终端处于熄屏状态的情况下，通过处于第一运行状态的所述摄像头采集第一图像。
其中，所述摄像头在所述第一运行状态下的运行功率小于预设功率值。
此步骤的实现方式可以参见步骤101中的描述，为避免重复，此处不再赘述。
步骤202、若所述第一图像具备目标对象类型的图像特征，控制所述摄像头进入第二运行状态，并通过处于所述第二运行状态的所述摄像头采集第二图像。
其中，所述摄像头在所述第二运行状态的运行功率高于在所述第一运行状态的运行功率。
此步骤的实现方式可以参见步骤102中的描述，为避免重复，此处不再赘述。
步骤203、若所述第二图像中不包含具备所述图像特征的图像，则将所述摄像头由所述第二运行状态切换为所述第一运行状态。
由于第一运行状态下的摄像头像素较低，可能会存在对图像的误识别。在此步骤中，移动终端对第二图像进行识别，判断第二图像中是否存在具备 上述目标对象类型的图像特征的图像。若第二图像中不包含具备上述目标对象类型的图像特征的图像，则表示移动终端对第一图像发生误识别，即第一图像实际上不存在具备上述图像特征的图像，摄像头由第二运行状态切换为第一运行状态。
例如，移动终端识别第一图像中包含二维码图像后，将摄像头由低功耗模式的第一运行状态切换为普通拍照模式的第二运行状态。由于普通拍照模式采集的第二图像的像素较高，基于第二图像识别的准确度较高。若识别第二图像中不存在二维码图像，则表示对第一图像存在误识别，将摄像头由第二运行状态切换为第一运行状态，可以节约功耗。
可选地，所述通过处于所述第二运行状态的所述摄像头采集第二图像之后，所述方法还包括：若所述第二图像中包含具备所述图像特征的完整图像，则控制所述移动终端亮屏，并显示对所述完整图像的识别结果。
在该实施方式中，移动终端对第二图像进行识别，判断第二图像中是否包含具备上述目标对象类型的图像特征的完整图像。其中，完整图像可以理解为具备上述目标对象类型的所有图像特征。例如，目标对象类型为二维码，二维码的图像特征包括：三个“回”型定位点、按照预设条件分布的几何图形。若检测到三个“回”型定位点，且几何图形的分布特征满足预设条件，则表示检测到完整的二维码图像。
若第二图像中包含具备上述图像特征的完整图像，则移动终端点亮屏幕，并在屏幕上显示对完整图像的识别结果。一方面，通过对第二图像进行识别可以提高对图像识别的准确率；另一方面，自动点亮屏幕并显示对完整图像的识别结果，便于用户进一步进行操作。
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。
可选地，所述输出用于指示所述第二图像不完整的提示信息，包括：控制所述移动终端的屏幕的部分区域亮屏，并在所述部分区域显示所述第二图像；或控制所述移动终端亮屏，并在所述移动终端的屏幕上显示所述第二图像。
在该实施方式中，可以包括两种显示第二图像的方式。
一种方式是移动终端点亮屏幕的部分区域，并在该部分区域显示第二图像。该方式可以理解为，在移动终端处于熄屏状态下，仅点亮熄屏界面上的部分区域，并在该部分区域上显示第二图像，具体实现可以参照相关技术。例如，如图2-1所示，移动终端处于锁屏且熄屏的状态，在屏幕的部分区域显示日期和二维码。在显示第二图像的过程中，不需要唤醒整个屏幕，即能够获取当前扫码的情况，能够节约能耗。
另一种方式是将移动终端的整个屏幕点亮，并在点亮的显示屏上显示第二图像。例如，如图2-2所示，在屏幕上显示扫码界面。
上述两种方式均可以在屏幕上显示不完整的图像，且可以进一步在屏幕上显示当前未获取完整的二维码数据的提示信息，用户可以基于不完整图像的特征或提示信息调整移动终端的位置，从而获得完整图像，提高对象识别效率。
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。
可选地，所述输出用于指示所述第二图像不完整的提示信息，包括：根据所述不完整图像的特征输出包含所述移动终端的移动方向的语音提示信息。
在该实施方式中，若第二图像中包含上述目标对象类型的图像特征的不完整图像，则移动终端可以根据采集的不完整图像的特征确定图像的偏移方向，从而确定需要偏移移动终端的方向。例如，如图2-1所示的二维码图像，由于移动终端仅采集到二维码的两个“回”型定位点，且二维码图像的几何图像位于“回”型定位点右侧，可以判定二维码图像相对移动终端向右偏移了，因此，移动终端需要相对二维码图像向右偏移，以采集二维码图像的完整图像。
移动终端输出包含移动终端的偏移方向的语音提示信息，以提示用户根据提示信息移动移动终端，从而提高对象的识别效率。
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。
为了进一步理解本实施例，以下结合流程图和具体实施方式举例说明。
如图2-3所示，摄像头在移动终端开机或熄屏时开启低功耗模式，即处 于第一运行状态下运行。低功耗模式下的摄像头采集图片，摄像头对图片进行初步识别，判断图片中是否存在二维码，即目标对象类型。若图片中不存在二维码，则低功耗摄像头继续采集图片。
若图片中存在二维码，则摄像头切换为正常拍照模式，即第二运行状态，并采集图片。由于正常拍照模式下的摄像头采集的图片像素高于低功耗模式下采集的图片像素，移动终端基于正常拍照模式下获取的图片再次识别是否包含二维码。
若识别上述图片中不包含二维码，则摄像头切换为低功耗模式；
若识别上述图片中包含完整的二维码，则跳转到二维码对应的界面；
若识别上述图片中包含不完整的二维码，则可以点亮屏幕并自动显示扫码界面；或者可以在熄屏状态下点亮屏幕的部分区域，并在该部分区域显示获取的图像，并提示用户当前未获取完整的二维码数据。用户可以基于显示的信息调整移动终端的位置，从而使移动终端扫码。
这样，移动终端不需要唤醒整个屏幕即可以获得扫码情况，能够节约能耗，且能够提高扫码效率。
本公开实施例的对象识别方法，在熄屏状态下，对摄像头在第一运行状态下采集的第一图像进行初步识别后，摄像头切换为第二运行状态并采集第二图像，并对第二图像进行识别，能够提高图像识别的准确度。在第二图像中不包含目标对象类型的图像特征的情况下，将第二运行状态切换为第一运行状态，能够节约功耗。
