具体实施例
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明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发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，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，都属于本发明保护的范围。
实施例一
参照图1，示出了本发明实施例提供的一种跟踪拍摄的方法的步骤流程图。
为了解决现有技术中用户不能及时的移动移动终端进行跟踪拍摄，会出现拍摄目标出画的问题，本实施例提供了一种跟踪拍摄的方法，如图1所示，该方法可以包括以下步骤：
步骤S101，移动终端接收开启跟踪拍摄模式的信号。
在本步骤中，移动终端可以包括：具有摄像头的手机和平板电脑。用户可以通过触发移动终端屏幕上显示的拍摄应用的图标或虚拟按键来开启拍摄应用，从而移动终端屏幕上会显示拍照界面。拍照界面上可以显示开启跟踪拍摄模式的虚拟按键，用户触发该开启跟踪拍摄模式的虚拟按键，从而移动终端会接收到开启跟踪拍摄模式的信号。
步骤S102，依据信号，在拍摄界面内选择跟踪拍摄的目标。
在本步骤中，移动终端可以依据该信号开启拍摄应用的跟踪拍摄模式。跟踪拍摄的目标是，拍摄界面中的某一个物体，是跟踪拍摄的参照物。显示拍摄界面中的物体较多，有些是物体是可以移动的，例如人、动物；有些物体可以是固定不动的，例如，家具、墙。由于跟踪拍摄的目的是动态追踪移动中的物体，因此，跟踪拍摄的目标往往是可以移动的物体，例如人脸、服饰和动物。
步骤S103，当跟踪拍摄的目标在拍摄画面内移动时，确定跟踪拍摄的目标的移动矢量。
在本步骤中，在跟踪拍摄过程中，跟踪拍摄的目标会发生移动，例如奔 跑、跳跃。当跟踪拍摄的目标在拍摄画面内移动时，可以通过测量跟踪拍摄的目标在拍摄画面中移动的速度和移动方向来确定跟踪拍摄的目标的移动矢量。
步骤S104，将移动矢量发送给夹持移动终端的云台，以使云台带动移动终端依据移动矢量移动，保持跟踪拍摄目标位于拍摄界面内。
在本步骤中，移动终端可以通蓝牙、红外、USB(Universal Serial Bus，通用串行总线)中的任意一种方式将移动矢量发送给夹持移动终端的云台。相应的，云台中可以设置有蓝牙接收器、红外接收器和/或USB接口来接收移动矢量。
通过本发明实施例提供的一种跟踪拍摄的方法，通过移动终端接收开启跟踪拍摄模式的信号；依据该信号，在拍摄界面内选择跟踪拍摄的目标；当跟踪拍摄的目标在拍摄画面内移动时，确定跟踪拍摄的目标的移动矢量；将移动矢量发送给夹持移动终端的云台，以使云台带动移动终端依据移动矢量移动，保持跟踪拍摄目标位于拍摄界面内，从而实现了对跟踪拍摄的目标的自动跟踪拍摄，防止跟踪拍摄的目标出画；并且解放了用户的双手，不需要用户手动移动移动终端，提高了用户体验。
在本发明一优选实施例中，移动终端确定的移动矢量可以包括：速度矢量和方向矢量；
则上述步骤S104可以优化为：将速度矢量和方向矢量发送给夹持移动终端的云台以使云台带动移动终端依据速度矢量和方向矢量，进行相同速度矢量和相同方向矢量的移动，保持跟踪拍摄目标位于拍摄界面内，从而提高了跟踪拍摄的精确度。
在本发明另一优选实施例中，拍摄界面内可以包括：预设跟踪拍摄区域，并且预设跟踪拍摄区域小于拍摄界面。该预设的跟踪拍摄区域可以是，在拍摄界面内的预设位置以预设的面积自动生成的，例如，预设的跟踪拍摄区域位于拍摄界面的中心位置，占拍摄界面面积的1/6；也可以是用户手动在拍摄界面中划定的，例如，用户在拍摄界面上以点击点为起点，以抬起点为终点，手动拉取一个矩形框作为预设的跟踪拍摄区域，当然预设的跟踪拍摄区 域也可以是圆形或椭圆形等形状区域。
则上述步骤S102可以优化为：依据信号，在拍摄界面的预设跟踪拍摄区域内选择跟踪拍摄的目标；
相应的上述步骤S104可以优化为：将移动矢量发送给夹持移动终端的云台，以使云台带动移动终端依据移动矢量移动，保持跟踪拍摄目标位于拍摄界面的预设跟踪拍摄区域内。
由于拍摄界面中可以容纳较多的物体，面积较小的预设跟踪拍摄区域容纳的物体较少，从而提高了选择跟踪拍摄的目标的精确度。
实施例二
参照图2，示出了本发明实施例提供的一种跟踪拍摄的移动终端的结构示意图。
本实施例提供了一种跟踪拍摄的移动终端可以执行上述实施例提供的一种跟踪拍摄的方法，如图2所示，该移动终端可以包括以下模块：
信号接收模块21、目标选择模块22、移动矢量确定模块23和移动矢量发送模块24。
在本发明实施例中，信号接收模块21，用于接收开启跟踪拍摄模式的信号；目标选择模块22，用于依据信号，在拍摄界面内选择跟踪拍摄的目标；移动矢量确定模块23，用于当跟踪拍摄的目标在拍摄画面内移动时，确定跟踪拍摄的目标的移动矢量；移动矢量发送模块24，用于将移动矢量发送给夹持移动终端的云台，以使云台带动移动终端依据移动矢量移动，保持跟踪拍摄目标位于拍摄界面内。
在信号接收模块21中，用户可以通过触发移动终端屏幕上显示的拍摄应用的图标或虚拟按键来开启拍摄应用，从而移动终端屏幕上会显示拍照界面。拍照界面上可以显示开启跟踪拍摄模式的虚拟按键，用户触发该开启跟踪拍摄模式的虚拟按键，从而移动终端会接收到开启跟踪拍摄模式的信号
在目标选择模块22中，可以依据该信号开启拍摄应用的跟踪拍摄模式。跟踪拍摄的目标是，拍摄界面中的某一个物体，是跟踪拍摄的参照物。显示拍摄界面中的物体较多，有些是物体是可以移动的，例如人、动物；有些物体可以是固定不动的，例如，家具、墙。由于跟踪拍摄的目的是动态追踪移 动中的物体，因此，跟踪拍摄的目标往往是可以移动的物体，例如人脸、服饰和动物。
在移动矢量确定模块23中，在跟踪拍摄过程中，跟踪拍摄的目标会发生移动，例如奔跑、跳跃。当跟踪拍摄的目标在拍摄画面内移动时，可以通过测量跟踪拍摄的目标在拍摄画面中移动的速度和移动方向来确定跟踪拍摄的目标的移动矢量。
在移动矢量发送模块24中，可以通蓝牙、红外、USB中的任意一种方式将移动矢量发送给夹持移动终端的云台。相应的，云台中可以设置有蓝牙接收器、红外接收器和/或USB接口来接收移动矢量。
本发明实施例提供的一种跟踪拍摄的移动终端，通过接收开启跟踪拍摄模式的信号；依据该信号，在拍摄界面内选择跟踪拍摄的目标；当跟踪拍摄的目标在拍摄画面内移动时，确定跟踪拍摄的目标的移动矢量；将移动矢量发送给夹持移动终端的云台，以使云台带动移动终端依据移动矢量移动，保持跟踪拍摄目标位于拍摄界面内，从而实现了对跟踪拍摄的目标的自动跟踪拍摄，防止跟踪拍摄的目标出画；并且解放了用户的双手，不需要用户手动移动移动终端，提高了用户体验。
在本发明一优选地移动终端中，移动矢量可以包括：速度矢量和方向矢量；
则上述移动矢量发送模块44具体用于，将速度矢量和方向矢量发送给夹持移动终端的云台以使云台带动移动终端依据速度矢量和方向矢量，进行相同速度矢量和相同方向矢量的移动，保持跟踪拍摄目标位于拍摄界面内，从而提高了跟踪拍摄的精确度。
在本发明另一优选地移动终端中，拍摄界面内可以包括：预设跟踪拍摄区域，并且预设跟踪拍摄区域小于拍摄界面。该预设的跟踪拍摄区域可以是，在拍摄界面内的预设位置以预设的面积自动生成的，例如，预设的跟踪拍摄区域位于拍摄界面的中心位置，占拍摄界面面积的1/6；也可以是用户手动在拍摄界面中划定的，例如，用户在拍摄界面上以点击点为起点，以抬起点为终点，手动拉取一个矩形框作为预设的跟踪拍摄区域，当然预设的跟踪拍摄区域也可以是圆形或椭圆形等形状区域。
则上述目标选择模块22具体用于，依据信号，在拍摄界面的预设跟踪拍摄区域内选择跟踪拍摄的目标；
则上述移动矢量发送模块24具体用于，将移动矢量发送给夹持移动终端的云台，以使云台带动移动终端依据移动矢量移动，保持跟踪拍摄目标位于拍摄界面的预设跟踪拍摄区域内。
由于拍摄界面中可以容纳较多的物体，面积较小的预设跟踪拍摄区域容纳的物体较少，从而提高了选择跟踪拍摄的目标的精确度。
