具体实施方式
为了能够更清楚地理解本申请的实施例的上述目的、特征和优点，下面结合附图和具体实施方式对本申请的实施例进行进一步的详细描述。需要说明的是，在不冲突的情况下，本申请的实施例及实施例中的特征可以相互组合。
在下面的描述中阐述了很多具体细节以便于充分理解本申请，但是，本申请的实施例还可以采用其他不同于在此描述的其他方式来实施，因此，本申请的保护范围并不限于下面公开的具体实施例的限制。
下面参照图2至图19描述根据本申请的一些实施例。
实施例一
如图2所示，本实施例提出的一种用于云台设备的视频录制方法，包括：
步骤S102：确定与云台设备通信连接的移动终端；
步骤S104：确定与移动终端对应的至少一个显示比例；
步骤S106：根据显示比例控制云台设备录制视频。
用于云台设备的视频录制方法，首先确定与云台设备连接的移动终端，确定与移动终端对应于一个或多个显示比例。显示比例为在移动终端的显示屏上显示的图像的长宽比，如常见的4：3，16：9，9：16，18：9等。 云台设备设有摄像装置，并可以使用摄像装置稳定地进行拍摄。在进行拍摄时，云台设备把拍摄到的视频图像转为视频信号，发送至移动终端，并在移动终端上进行显示。由于云台设备和移动终端相互独立，因此云台设备发送的图像信号在移动终端上进行显示时，可能会因云台设备发送的图像比例与移动终端的屏幕比例不能匹配，导致图像无法在移动终端正确显示，出现图像被拉伸变形，或出现黑边甚至图像被裁剪的情况。因此，本实施例中的视频录制方法中，云台设备在确定了通信连接的移动终端后，会确定与移动终端对应的一个显示比例，并根据显示比例控制云台设备录制视频。由于云台设备在确定了移动终端后，会根据移动终端确定的显示比例录制视频，因此生成的图像信号，可以符合移动终端的显示比例，使拍摄的视频能够较好的在移动终端进行显示。
进一步地，用户可以根据拍摄效果的要求，人为的选择并确定显示比例。由于云台设备与移动终端为相对独立的设备，相互之间只通过通信连接，因此，用户可以根据拍摄效果在移动终端上确定显示比例，云台设备在与移动终端进行通信连接后，获取移动终端上设定的显示比例，并根据显示比例控制云台设备录制视频。
需要说明的是，移动终端的显示比例可以有多个不同的显示比例，云台设备在与移动终端通信连接后，可以同时获取多个显示比例。
实施例二
如图3所示，本实施例提出的一种用于云台设备的视频录制方法，包括：
步骤S202：确定与云台设备通信连接的移动终端；
步骤S204：控制云台设备的视频录制方向与拍摄方向相同；
步骤S206：确定与视频录制方向对应的至少一个显示比例；
步骤S208：根据显示比例控制云台设备录制视频。
用于云台设备的视频录制方法，首先确定与云台设备连接的移动终端为手机，确定与手机对应于一个或多个显示比例。显示比例为在手机的显示屏上显示的图像的长宽比，如常见的4：3，16：9，9：16，18：9等。云台设备设有摄像装置，并可以使用摄像装置稳定地进行拍摄。在进行拍 摄时，云台设备把拍摄到的视频图像转为视频信号，发送至手机，并在手机上进行显示。由于云台设备和手机相互独立，因此云台设备发送的图像信号在手机上进行显示时，可能会因云台设备发送的图像比例与手机的屏幕比例不能匹配，导致图像无法在手机正确显示，出现图像被拉伸变形，或出现黑边甚至图像被裁剪的情况。因此，本实施例中的视频录制方法中，云台设备在确定了通信连接的手机后，会确定与手机对应的一个显示比例，并根据显示比例控制云台设备录制视频。由于云台设备在确定了手机后，会根据手机确定的显示比例录制视频，因此生成的图像信号，可以符合手机的显示比例，使拍摄的视频能够较好的在手机进行显示。
进一步地，用户可以根据拍摄效果的要求，人为的选择并确定显示比例。由于云台设备与手机为相对独立的设备，相互之间只通过通信连接，因此，用户可以根据拍摄效果在手机上确定显示比例，云台设备在与手机进行通信连接后，获取手机上设定的显示比例，并根据显示比例控制云台设备录制视频。
需要说明的是，手机的显示比例可以有多个不同的显示比例，云台设备在与手机通信连接后，可以同时获取多个显示比例。
由于手机的显示方向可以为横向或竖向。如图4所示，手机为竖向显示方式。如图5所示，手机为横向显示方式。针对手机的不同显示方式，在确定移动终端的显示比例之间，还会首先确定移动终端的拍摄方向。
在确定移动终端的拍摄方向后，会控制云台设备的视频录制方向与拍摄方向相同，以使设备的视频录制方向能够与移动终端相匹配，最终在移动终端显示的图像能够在移动终端的显示屏上正确的显示，提高图像在显示屏的显示的面积，避免出现较大面积的黑边，或者图像拉伸。
通常来说，当移动终端在拍摄时会根据拍摄的场景或目标，选取横向或竖向构图进行拍摄。传统云台设备，由于不能根据移动终端的拍摄方向进行对应的调整，如用户需要竖向拍摄，但是云台设备由于不能根据用户的拍摄需求进行对应调整，因此可能发送到移动终端的图像还是为横向，在竖向显示时，只能在图像上下两端增加黑边，无法满足用户拍摄需求。首先确定手机显示比例，可以有效的避免因显示比例不匹配导致出现图像 在显示时出现黑边、图像被拉伸等情况。
实施例三
如图6所示，本实施例提出的一种用于云台设备的视频录制方法，包括：
步骤S302：确定与云台设备通信连接的移动终端；
步骤S304：确定与移动终端对应的至少一个显示比例；
步骤S306：若显示比例为一个，则控制云台设备以显示比例录制视频；
步骤S308：若显示比例为多个，则确定多个显示比例中视角参数最大的一个显示比例；
步骤S310：控制云台设备以视角参数最大的显示比例录制视频。
用于云台设备的视频录制方法，首先确定与云台设备连接的手机，确定与手机对应于一个或多个显示比例。显示比例为在手机的显示屏上显示的图像的长宽比，如常见的4：3，16：9，9：16，18：9等。云台设备设有摄像装置，并可以使用摄像装置稳定地进行拍摄。在进行拍摄时，云台设备把拍摄到的视频图像转为视频信号，发送至手机，并在手机上进行显示。由于云台设备和手机相互独立，因此云台设备发送的图像信号在手机上进行显示时，可能会因云台设备发送的图像比例与手机的屏幕比例不能匹配，导致图像无法在手机正确显示，出现图像被拉伸变形，或出现黑边甚至图像被裁剪的情况。因此，本实施例中的视频录制方法中，云台设备在确定了通信连接的手机后，会确定与手机对应的一个显示比例，并根据显示比例控制云台设备录制视频。由于云台设备在确定了手机后，会根据手机确定的显示比例录制视频，因此生成的图像信号，可以符合手机的显示比例，使拍摄的视频能够较好的在手机进行显示。
对于手机而言，显示比例可以为一个或多个。对于手机显示屏幕来说，最常用的显示比例为手机屏幕的长宽比。但是由于当前的手机的型号多样，手机屏幕的长宽比也不同，如16：9，18：9等多种类型。因此一些手机应用所使用的显示比例不一定能够与用户所使用的手机的显示屏幕的长宽比吻合。为了防止用户上传的视频的显示比例能够统一，手机应用会规定上传视频的显示比例。为此，视频录制方法应能够确定显示比例，并使云台 设备能够按照设定的显示比例录制视频。
很明显，显示比例为一个时，云台设备应根据该显示比例录制视频。当显示比例为多个时，云台设备则会确定多个显示比例中视角参数最大的一个的显示比例。其中，视角参数为摄像头可以接收影像的角度范围，也可以称为视野。可以理解，视角参数越大，云台设备拍摄到的范围就越大，视角参数大的显示比例拍摄到的图像，可以包含视角参数小的显示比例拍摄到的图像。因此，确定多个显示比例中视角参数最大的显示比例作为当前录制视频的显示比例，可以保证图像中其他显示比例的图像也能够完整的拍摄到图像。
当显示比例为多个时，为了方便用户进行选取或设定，在移动终端的显示界面中显示多个对应于不同显示比例的参考标记，用户可以根据参考标记对显示比例进行选取和设定。在用户选取了显示比例的参考标记后，云台设备会接收对应的选取指令，以获知用户设定的显示比例，并根据选取指令对应的显示比例录制视频。
通过这种方式，用户可以人机交互的方式，方便的根据拍摄或构图的需要，选取并设定显示比例，以达到最佳的拍摄效果。如图7所示，在手机屏幕上以套叠的方式表示显示比例的参考标记106。如图8所示，在手机屏幕上以九宫格的方式显示不同的显示比例的参考标记106。
进一步地，为了表示方便，同一个显示比例，可以使用多个参考标记进行表示。参考标记的表示形式也可以有多种，如直线框、虚线框、数字形式等。最为常见的是虚线框。为了显示方便或为了便于在屏幕中展示，虚线框会对实际显示屏幕进行缩小。可以理解，对于同一显示比例，如果使用多个参考标记与之对应，那么多个参考标记之间，必然为等比例缩放。

用于云台设备的视频录制方法，首先确定与云台设备连接的手机，确定与手机对应于一个或多个显示比例。显示比例为在手机的显示屏上显示的图像的长宽比，如常见的4：3，16：9，9：16，18：9等。云台设备设有摄像装置，并可以使用摄像装置稳定地进行拍摄。在进行拍摄时，云台设备把拍摄到的视频图像转为视频信号，发送至手机，并在手机上进行显示。由于云台设备和手机相互独立，因此云台设备发送的图像信号在手机上进行显示时，可能会因云台设备发送的图像比例与手机的屏幕比例不能匹配，导致图像无法在手机正确显示，出现图像被拉伸变形，或出现黑边甚至图像被裁剪的情况。因此，本实施例中的视频录制方法中，云台设备在确定了通信连接的手机后，会确定与手机对应的一个显示比例，并根据显示比例控制云台设备录制视频。由于云台设备在确定了手机后，会根据手机确定的显示比例录制视频，因此生成的图像信号，可以符合手机的显示比例，使拍摄的视频能够较好的在手机进行显示。
对于手机而言，显示比例可以为一个或多个。对于手机显示屏幕来说，最常用的显示比例为手机屏幕的长宽比。但是由于当前的手机的型号多样，手机屏幕的长宽比也不同，如16：9，18：9等多种类型。因此一些手机应用所使用的显示比例不一定能够与用户所使用的手机的显示屏幕的长宽比吻合。为了防止用户上传的视频的显示比例能够统一，手机应用会规定上传视频的显示比例。为此，视频录制方法应能够确定显示比例，并使云台设备能够按照设定的显示比例录制视频。
进一步地，云台设备在录制视频时，会根据原始录制比例录制视频，生成原始视频文件。原始视频是云台设备本身的原始录制比例，可以理解为云台设备可达到的最大显示比例。云台设备在拍摄到原始录制比例的图像后，根据移动终端的显示比例，对原始比例的视频进行截取，生成符合移动终端的显示比例的视频，并发送到移动终端，这样可以压缩发送到移 动终端的数据量，提高视频传送的效率。
但是为了能够保证云台设备录制的视频文件更完整，在用户需要查看不同显示比例的图像时，云台设备能够相应的进行提供，云台设备在录制视频时，首先根据原始录制比例录制视频，并生成原始视频文件，然后再根据移动终端的显示比例，对原始视频文件进行处理，生成显示视频文件。
进一步地，当根据显示比例控制云台设备开始录制视频后，显示比例会被锁定，以防止在录制过程中，显示比例发生改变，影响录制效果。
如移动终端为手机时，通常在手机转动时，手机屏幕的显示比例有可能会跟随发生转动。为了防止手机在转动时发生的屏幕转动导致云台设备的显示比例发生改变，影响实际拍摄效果，因此在云台设备开始录制时，即锁定显示比例，以保证视频录制效果。
实施例五
如图10所示，本实施例提出的一种用于云台设备的视频录制方法，包括：
步骤S502：确定与云台设备通信连接的移动终端；
步骤S504：判断连接状态是否为无线通信连接；
若是，则执行步骤S506：确定与云台设备通信连接的移动终端；若否，则直接结束；
步骤S508：确定与移动终端对应的至少一个显示比例；
步骤S510：根据显示比例控制云台设备录制视频。
在本实施例中，云台设备和移动终端的连接状态，可以为无线通信连接或有线连接。当云台设备与移动终端为有线连接时，其连接状态已固定，因此云台设备不需要确定与之相连的移动终端。而当云台设备与移动终端为无线连接时，云台设备可以根据需要，与不同的移动终端进行连接，在确定相互之间的连接关系后，再进行通信。因此，在确定云台设备与移运终端的连接状态之前，应首先判断连接是否为无线通信状态，当为无线通信状态，需要确定云台设备与移动终端之间的连接，以保证后序的步骤可以正确的执行。
在确定了云台设备与移动终端的连接状态后，确定与移动终端对应于一 个或多个显示比例。显示比例为在移动终端的显示屏上显示的图像的长宽比，如常见的4：3，16：9，9：16，18：9等。云台设备设有摄像装置，并可以使用摄像装置稳定地进行拍摄。在进行拍摄时，云台设备把拍摄到的视频图像转为视频信号，发送至移动终端，并在移动终端上进行显示。由于云台设备和移动终端相互独立，因此云台设备发送的图像信号在移动终端上进行显示时，可能会因云台设备发送的图像比例与移动终端的屏幕比例不能匹配，导致图像无法在移动终端正确显示，出现图像被拉伸变形，或出现黑边甚至图像被裁剪的情况。因此，本实施例中的视频录制方法中，云台设备在确定了通信连接的移动终端后，会确定与移动终端对应的一个显示比例，并根据显示比例控制云台设备录制视频。由于云台设备在确定了移动终端后，会根据移动终端确定的显示比例录制视频，因此生成的图像信号，可以符合移动终端的显示比例，使拍摄的视频能够较好的在移动终端进行显示。
进一步地，用户可以根据拍摄效果的要求，人为的选择并确定显示比例。由于云台设备与移动终端为相对独立的设备，相互之间只通过通信连接，因此，用户可以根据拍摄效果在移动终端上确定显示比例，云台设备在与移动终端进行通信连接后，获取移动终端上设定的显示比例，并根据显示比例控制云台设备录制视频。
实施例六
如图13所示，本实施例提出的一种用于云台设备的视频录制方法，包括：
步骤S802：确定与云台设备通信连接的移动终端；
步骤S804：判断连接状态是否为无线通信连接；
若是，则执行步骤S806：确定与云台设备通信连接的移动终端；
步骤S808：确定移动终端的拍摄方向；
步骤S810：控制云台设备的视频录制方向与拍摄方向相同；
步骤S812：确定与视频录制方向对应的至少一个显示比例；
步骤S814：判断显示比例是否为多个；
若是，则执行步骤S816：确定多个显示比例中视角参数最大的一个显 示比例；
步骤S818：控制云台设备以视角参数最大的显示比例录制视频；
若步骤S814的判断结果为是，还可能执行步骤S820：在移动终端的显示界面中显示多个对应于显示比例的参考标记；
步骤S822：接收与任一参考标记对应的选取指令；
步骤S824：根据选取指令，根据参考标记对应的显示比例显示录制界面；
若步骤S814的判断结果为否，则执行步骤S826：控制云台设备以显示比例录制视频；
步骤S828：锁定显示比例；
步骤S830：获取云台设备的原始录制比例；
步骤S832：根据原始录制比例录制视频，生成原始视频文件。
本实施例中，用于云台设备的视频录制方法，首先确定与云台设备连接的移动终端，确定与移动终端对应于一个或多个显示比例。显示比例为在移动终端的显示屏上显示的图像的长宽比，如常见的4：3，16：9，9：16，18：9等。云台设备设有摄像装置，并可以使用摄像装置稳定地进行拍摄。在进行拍摄时，云台设备把拍摄到的视频图像转为视频信号，发送至移动终端，并在移动终端上进行显示。由于云台设备和移动终端相互独立，因此云台设备发送的图像信号在移动终端上进行显示时，可能会因云台设备发送的图像比例与移动终端的屏幕比例不能匹配，导致图像无法在移动终端正确显示，出现图像被拉伸变形，或出现黑边甚至图像被裁剪的情况。因此，本实施例中的视频录制方法中，云台设备在确定了通信连接的移动终端后，会确定与移动终端对应的一个显示比例，并根据显示比例控制云台设备录制视频。由于云台设备在确定了移动终端后，会根据移动终端确定的显示比例录制视频，因此生成的图像信号，可以符合移动终端的显示比例，使拍摄的视频能够较好的在移动终端进行显示。
进一步地，用户可以根据拍摄效果的要求，人为的选择并确定显示比例。由于云台设备与移动终端为相对独立的设备，相互之间只通过通信连接，因此，用户可以根据拍摄效果在移动终端上确定显示比例，云台设备 在与移动终端进行通信连接后，获取移动终端上设定的显示比例，并根据显示比例控制云台设备录制视频。
需要说明的是，移动终端的显示比例可以有多个不同的显示比例，云台设备在与移动终端通信连接后，可以同时获取多个显示比例。
进一步地，在确定移动终端的显示比例之前，还会首先确定移动终端的拍摄方向。移动终端的拍摄方向通常包括横向和竖向，进一步地，也可以包括任意角度的拍摄方向。
常见的移动终端如手机，显示屏幕为长方形，用户可以选择横向进行拍摄也可以选择竖向进行拍摄，不同的拍摄方向对应的显示比例不同。如横向显示比例为16：9的手机显示屏，当拍摄方向为横向时，图像的显示比例为16：9，当拍摄方向为竖向时，图像的显示比例为9：16。因此，云台设备会根据移动终端的拍摄方向，并根据拍摄方向确定显示比例。
进一步地，在确定移动终端的显示比例之前，还会首先确定移动终端的拍摄方向。移动终端的拍摄方向通常包括横向和竖向，进一步地，也可以包括任意角度的拍摄方向。
常见的移动终端如手机，显示屏幕为长方形，用户可以选择横向进行拍摄也可以选择竖向进行拍摄，不同的拍摄方向对应的显示比例不同。如横向显示比例为16：9的手机显示屏，当拍摄方向为横向时，图像的显示比例为16：9，当拍摄方向为竖向时，图像的显示比例为9：16。因此，云台设备会根据移动终端的拍摄方向，并根据拍摄方向确定显示比例。
进一步地，在确定移动终端的拍摄方向后，会控制云台设备的视频录制方向与拍摄方向相同，以使设备的视频录制方向能够与移动终端相匹配，最终在移动终端显示的图像能够在移动终端的显示屏上正确的显示，提高图像在显示屏的显示的面积，避免出现较大面积的黑边，或者图像拉伸。
通常来说，当移动终端在拍摄时会根据拍摄的场景或目标，选取横向或竖向构图进行拍摄。传统云台设备，由于不能根据移动终端的拍摄方向进行对应的调整，如用户需要竖向拍摄，但是云台设备由于不能根据用户的拍摄需求进行对应调整，因此可能发送到移动终端的图像还是为横向，在竖向显示时，只能在图像上下两端增加黑边，无法满足用户拍摄需求。
进一步地，显示比例可以为一个或多个。很明显，显示比例为一个时，云台设备应根据该显示比例录制视频。当显示比例为多个时，云台设备则会确定多个显示比例中视角参数最大的一个的显示比例。其中，视角参数为摄像头可以接收影像的角度范围，也可以称为视野。可以理解，视角参数越大，云台设备拍摄到的范围就越大，视角参数大的显示比例拍摄到的图像，可以包含视角参数小的显示比例拍摄到的图像。因此，确定多个显示比例中视角参数最大的显示比例作为当前录制视频的显示比例，可以保证图像中其他显示比例的图像也能够完整的拍摄到图像。
进一步地，当显示比例为多个时，为了方便用户进行选取或设定，在移动终端的显示界面中显示多个对应于不同显示比例的参考标记，用户可以根据参考标记对显示比例进行选取和设定。在用户选取了显示比例的参考标记后，云台设备会接收对应的选取指令，以获知用户设定的显示比例，并根据选取指令对应的显示比例录制视频。
通过这种方式，用户可以人机交互的方式，方便的根据拍摄或构图的需要，选取并设定显示比例，以达到最佳的拍摄效果。
需要说明的是，为了表示方便，同一个显示比例，可以使用多个参考标记进行表示。参考标记的表示形式也可以有多种，如直线框、虚线框、数字形式等。最为常见的是虚线框。为了显示方便或为了便于在屏幕中展示，虚线框会对实际显示屏幕进行缩小。可以理解，对于同一显示比例，如果使用多个参考标记与之对应，那么多个参考标记之间，必然为等比例缩放。
进一步地，云台设备在录制视频时，会根据原始录制比例录制视频，生成原始视频文件。原始视频是云台设备本身的原始录制比例，可以理解为云台设备可达到的最大显示比例。云台设备在拍摄到原始录制比例的图像后，根据移动终端的显示比例，对原始比例的视频进行截取，生成符合移动终端的显示比例的视频，并发送到移动终端，这样可以压缩发送到移动终端的数据量，提高视频传送的效率。
但是为了能够保证云台设备录制的视频文件更完整，在用户需要查看不同显示比例的图像时，云台设备能够相应的进行提供，云台设备在录制 视频时，首先根据原始录制比例录制视频，并生成原始视频文件，然后再根据移动终端的显示比例，对原始视频文件进行处理，生成显示视频文件。
进一步地，当根据显示比例控制云台设备开始录制视频后，显示比例会被锁定，以防止在录制过程中，显示比例发生改变，影响录制效果。
如移动终端为手机时，通常在手机转动时，手机屏幕的显示比例有可能会跟随发生转动。为了防止手机在转动时发生的屏幕转动导致云台设备的显示比例发生改变，影响实际拍摄效果，因此在云台设备开始录制时，即锁定显示比例，以保证视频录制效果。
实施例七
如图11所示，本实施例提出的一种用于移动终端的视频录制方法，包括：
步骤S602：确定移动终端的屏幕显示比例；
步骤S604：根据屏幕显示比例确定参考标记；
步骤S606：获取与任一参考标记对应的选取指令；
步骤S608：根据选取指令，根据参考标记对应的显示比例显示云台设备的录制界面。
本实施例中，移动终端的屏幕显示比例即移动终端屏幕的长宽比。以手机为例，不同的手机，屏幕显示比例有多种，常见的有16:9，16:10等。不同的屏幕显示比例，其显示的图像效果不同。如果云台设备录制的视频与移动终端的屏幕显示比例不能匹配，则会出现视频图像被拉伸或出现黑边的情况。因此，移动终端首先确定屏幕显示比例。并根据屏幕显示比例确定参考标记，并进一步获取与参考标记对应的选取指令。云台设备接收到移动终端设定的选取指令后，会根据选取指令设定的显示比例进行视频录制，并将录制的视频发送至移动终端。移动终端接到云台设备发送的视频，根据预先设定的选取指令，确定显示比例，可以将云台设备发送的视频按照用户预先的设定正确的在显示屏进行显示。
可以理解，对于固定的移动终端，其屏幕显示比例也是固定的。云台设备可以包括不同的显示比例，这些显示比例都与屏幕显示比例相对应，因此对应于屏幕显示比例的显示比例之间为等比例缩放。不同的显示比例， 其显示效果不同。
进一步地，为了便于进行区分多个显示比例，不同的显示比例对应不同的参考标记。可以通过确定参考标记，使云台设备能够根据参考标记确定视频录制的显示比例，以符合移动终端的使用需求。
在另一个具体的实施例中，如图12所示，用于移动终端的视频录制方法，包括：
步骤S702：获取移动终端内的至少一个视频分享软件；
步骤S704：确定每个视频分享软件的视频显示比例；
步骤S706：根据至少一个视频显示比例确定参考标记；
步骤S708：获取与任一参考标记对应的选取指令；
步骤S710：根据选取指令，根据参考标记对应的显示比例显示云台设备的录制界面。
其中，用于移动终端的视频录制方法，可以用于为视频分享软件录制视频。当前流行的手机视频分享软件，如抖音、快手、斗鱼等，都支持用户自己通过手机录制视频后进行上传。不同的视频分享软件可接受的显示比例可能不同。为了使用户自己录制的视频能够适用于对应的视频分享软件，因此本实施例中用于移动终端的视频录制方法可以根据视频分享软件确定视频显示比例。移动终端首先获取移动终端内的一个或多个视频分享软件，并确定每个视频分享软件所要求的视频显示比例。根据每个视频分享软件确定对应的参考标记，以确定云台设备的视频拍摄。
以抖音为例，预设显示比例为6：19，即竖屏显示。此时，如果不对云台设备的显示比例进行设定，则可能出来录制的视频显示不全，或者上下出现黑边的情况，影响最终的效果。
实施例八

在确定连接后，移动终端确定屏幕的显示比例。根据实际情况不同，移动终端的屏幕显示比例可以有多个。其中，移动终端的屏幕显示比例与云台设备的显示比例相对应。移动终端将对应的显示比例发送至云台设备，如果显示比例为多个，云台设备会确定视角参数最大的显示比例，并根据视角参数最大的显示比例控制云台设备录制视频。
录制的视频可以发送至移动终端，移动终端接到云台设备发送的视频，根据预先设定的选取指令，确定显示比例，可以将云台设备发送的视频按照用户预先的设定正确的在显示屏进行显示。
其中，移动终端可以包括不同的显示比例，显示比例为移动终端的显示屏上显示的图像的长宽比。不同的显示比例，其显示效果不同。为了保证云台设备拍摄的图像能够符合设定的要求，在进行视频录制前，需要确定移动终端的屏幕显示比例。对于同一个移动终端，可以有多个显示比例，为了便于进行区分，不同的显示比例对应不同的参考标记。能过确定参考标记，使云台设备能够根据参考标记确定视频录制的显示比例，以符合移动终端的使用需求。
在另一个具体的实施例中，如图15所示，一种用于云台设备和移动终端的视频录制方法，包括：

在本实施例的移动终端内，安装有视频分享软件，用于分享从云台设备录制的视频。云台设备首先确定与移动终端的连接状态是否为无线连接，以保证后序的步骤可以正确的执行。
如图4所示，云台设备102在确定与移动终端100的无线连接后，移动终端100获取移动终端100内的视频分享软件，并确定每个视频分享软件的视频显示比例。
其中，移动终端的视频显示比例与云台设备的显示比例相对应。移动终端将对应的显示比例发送至云台设备。如果显示比例为多个，云台设备会确定视角参数最大的显示比例，并根据视角参数最大的显示比例控制云台设备录制视频。
云台设备录制的视频可以发送至移动终端，移动终端接到云台设备发送的视频，根据预先设定的选取指令，确定显示比例，可以将云台设备发送的视频按照用户预先的设定正确的在显示屏进行显示。
其中，移动终端可以包括不同的显示比例，显示比例为移动终端的显示屏上显示的图像的长宽比。不同的显示比例，其显示效果不同。为了保证云台设备拍摄的图像能够符合设定的要求，在进行视频录制前，需要确定移动终端的屏幕显示比例。对于同一个移动终端，可以有多个显示比例， 为了便于进行区分，不同的显示比例对应不同的参考标记。能过确定参考标记，使云台设备能够根据参考标记确定视频录制的显示比例，以符合移动终端的使用需求。

实施例十五
如图18所示，本实施例提出的一种用于云台设备的视频录制方法，包括：
步骤S1102：通过设备应用与手机取得通信，向用户发送请求，确认是否可以读取手机型号；
步骤S1104：基于手机型号获取的显示比例或根据用户设置确定显示比例；
步骤S1106：提示用户是否将录制视频的显示比例确定为竖屏16:9或某一具体尺寸，以方便在社交软件中分享视频；
步骤S1108：云台设备以最大视角参数，在设备应用中显示相应的比例虚线，虚线框以用户期望比例或手机所能获得的最大分辨率在该视角参数下最佳显示，方便用户做构图并录制；
步骤S1110：云台设备以原最大视角保存原视频，但记录相应模式期望比例，用户下载时即生成相应的期望比例视频。
本实施例中的云台设备，可以适配于不同屏幕尺寸的手机终端。在使 用该云台设备的手机终端中，装有与云台设备对应的设备应用，可以在该应用中对云台设备进行设置。在手机终端的设备应用中，可以设置按钮或提醒，当设备应用检测到手机与云台设备为无线连接状态时，提示用户是否开启云台设备匹配手机屏幕的横屏或竖屏拍摄功能。
在云台设备通过设备应用与手机取得通信，向用户发送请求，确认是否可以读取手机型号。此外，云台设备还可以通过蓝牙的连接方式与手机取得通信。云台设备的视频录制方法会基于手机型号获取显示比例，用户也可以在该模式下设置期望显示，得到模式期望的显示比例。
进一步地，云台设备的视频录制方法会提示用户是否将视频尺寸定为竖屏尺寸，如竖屏的16:9，以便用户在如抖音等社交软件上进行视频分享。
进一步地，云台设备以原先最大的FOV(即视角参数)，或者做了畸变较正的FOV，在设备应用中显示相应的比例虚线，虚线框以用户期望比例或手机比例所能获得的最大分辨率在该FOV下最佳显示，方便用户做构图去录制。当然，直接显示模式期望比例，也可以实现上述效果。
进一步地，云台设备以最大的FOV，在设备应用中直接显示模式期望比例，并在该FOV下最佳显示，方便用户做构图并进行录制。这里需要说明的是，在视频录制中，云台设备的视频录制方法会锁定当前用户期望的显示比例，在录制过程中不会随手机或云台姿势变化而改变当前期望的显示比例(即横屏变为竖屏时不进行切换)。
如图19所示，图中由大到小排列的参考标记为参考标记一108，参考标记二110，参考标记三112的长宽比例均为一样，均为用户期望比例。在用户的手机屏幕上，设备应用可以自动检测用户屏幕大小数值，基于屏幕调整虚线比例至图19中的参考标记一108，尽可能达到屏幕全占比，以达到最佳显示。因此，本实施例中视频录制方法，可以解决用户在使用云台设备录制视频，将录制的视频分享到手机后，因为视频尺寸不匹配，导致视频显示时，出现视频图像被拉伸、裁剪或黑边的情况，保证视频图像能够与屏幕完美匹配，提升用户使用的体验度，方便用户构图。此外，在使用云台设备录制视频时，还可以满足用户期望拍摄竖屏视频的需求。
进一步地，云台设备能够以设备最大的FOV保存原视频，但同时记录 相应的期望比例，用户下载视频时，即生成相应的期望比例视频。
进一步地，用户还可以后期调整显示比例，对保存的原视频进行修改，以便在视频共享软件中进行视频共享。
根据本申请的视频录制方法、云台设备和移动终端和可读存储介质的实施例，可以根据移动终端设定的显示比例，确定云台设备录制视频的显示比例，使录制的视频能够满足移动终端或视频共享软件对显示比例的需求。可以减少用户拍摄录制竖屏视频或照片后使用社交软件分享时的再编辑时间和精力，方便用户构图，满足用户期望拍摄竖屏视频的需求。
