日常生活中，用户经常会使用拍摄终端进行自拍或让他人协助拍摄。但在一些情况下，用户调整拍摄终端的姿态后，可能会出现不方便进行拍摄的情况，此时，需要通过将拍摄终端的拍摄画面共享给远程控制终端，从而使远程控制终端可以控制拍摄终端进行远程拍摄。
相关技术中，可以在拍摄终端接入的无线网络或热点对应的局域网中通过UDP广播来发现远程控制终端，从而连接拍摄终端和远程控制终端后通过TCP传输视频预览帧和传递拍摄指令。然而，完全通过UDP广播接收相关数据，会增加路由器工作负荷，并且，由于部分路由器会限制UDP广播或组播，从而无法保证拍摄终端和远程控制终端建立远程拍摄连接。
为解决上述问题，本公开实施例提供一种远程拍摄方法、装置、设备及存储介质，在组播异常时，通过在局域网中确定第二终端的主机互联网协议地址范围，遍历向局域网中的第二终端发送单播消息，从而保证了拍摄终端和远程控制终端建立远程拍摄连接。
下面对于本申请涉及的远程拍摄方法的应用场景进行说明。
图1为本申请实施例提供的一种远程拍摄方法的应用场景示意图。如图1所示，当用户使用拍摄终端101进行拍摄前，可以在拍摄终端101接入的无线网络或热点对应的局域网中搜索远程控制终端102，从而将拍摄终端101的拍摄画面共享给远程控制终端102，并通过远程控制终端102控制拍摄终端101进行远程拍摄。当拍摄终端101搜索到远程控制终端102后，可以与远程控制终端102建立远程拍摄连接，随后，由远程控制终端102向拍摄终端101发送拍摄指令。
其中，拍摄终端101为具有拍摄功能的终端，拍摄终端101和远程控制终端102可以为平板电脑(Portable Android Device，简称PAD)、带无线收发功能的电脑、虚拟现实(Virtual Reality，简称VR)终端设备、增强现实(Augmented Reality，简称AR)终端设备、工业控制(Industrial Control)中的无线终端、无人驾驶(Self-Driving)中的无线终端、远程手术(Remote Medical Surgery)中的无线终端、智能电网(Smart Grid)中的无线终端、智慧家庭(Smart Home)中的无线终端等。本申请实施例中，用于实现终端的功能的装置可以是终端，也可以是能够支持终端实现该功能的装置，例如芯片系统，该装置可以被安装在终端中。本申请实施例中，芯片系统可以由芯片构成，也可以包括芯片和其他分立器件。
应理解，本申请技术方案的应用场景可以是图1中的场景，但不限于此，还可以应用于其他需要远程拍摄的场景中。
可以理解，上述远程拍摄方法可以通过本申请实施例提供的远程拍摄装置实现，远程拍摄装置可以是某个设备的部分或全部，例如为终端设备或终端设备的处理器。
下面以具体地实施例对本公开实施例的技术方案进行详细说明。下面这几个具体的实施例可以相互结合，对于相同或相似的概念或过程可能在某些实施例不再赘述。
参考图2，图2为本公开实施例提供的一种远程拍摄方法的流程示意图。本实施例的执行主体为第一终端，本实施例涉及的第一终端如何搜索作为远程控制终端的第二终端的过程。该远程拍摄方法包括：
S201、第一终端接收远程拍摄请求，远程拍摄请求用于指示第一终端搜索第二终端，第二终端用于向第一终端发送拍摄指令。
在本公开中，当用户使用第一终端进行远程拍摄前，可以向第一终端输入远程拍摄请求，从而使第一终端搜索作为远程控制终端的第二终端。
应理解，上述第一终端可以为进行拍摄的拍摄终端，例如，手机、平板电脑、相机等。上述第二终端为共享第一终端的拍摄画面并向第一终端发送拍摄指令的远程控制终端，例如，智能手表、手机、遥控器等。
应理解，本申请实施例对于如何向第一终端输入远程拍摄请求不做限制，在一些实施例中，用户可以通过在第一终端上触发相应控件，向第一终端输入远程拍摄请求。
S202、若第一终端接入的无线网络或热点对应的局域网的组播异常，则第一终端在局域网中确定第二终端的主机互联网协议地址范围。
在本公开中，当第一终端接收到用户输入的远程拍摄请求后，首先尝试使用组播搜索第二终端，若第一终端接入的无线网络或热点对应的局域网中组播异常，则在局域网中确定第二终端的主机互联网协议地址(Internet Protocol，简称IP)范围。
应理解，本申请实施例对于上述组播的类型不做限制，在一些实施例中，上述组播可以为UDP组播。
其中，无线网络或热点可以包括WiFi、手机热点、车载热点等。
在一些实施例中，第一终端首先可以确定第一终端是否接入无线网络或热点，若第一终端未接入无线网络或热点，则可以在第一终端的显示界面上显示提示信息，提示信息用于提示用户将第一终端接入无线网络或热点。若第一终端接入无线网络或热点，则加入组播并开始监听组播。随后，第一终端可以确定组播是否正常开启。若组播正常，则在局域网中向第二终端发送组播消息，组播消息也用于请求在局域网中获取第二终端的信息。若组播异常，则在局域网中确定第二终端的主机互联网协议地址范围。
在本申请实施例中，对于如何确实组播是否正常开启不做限制，在一些实施例中，可以通过第一终端在发送组播后的预设时间内是否收到第二终端发送的反馈消息来确定。示例性的，该预设时间可以为3秒。若第一终端在发送组播后的3秒内，接收到至少一个第二终端发送的反馈消息，则确定组播正常。若第一终端在发送组播后的3秒内，未接收到至少一个第二终端发送的反馈消息，则确定组播异常。
在本公开中，第一终端首先使用组播来搜索第二终端，由于使用组播来替换广播，从而可以减少在搜索第二终端的过程中收到数据的终端，从而可以降低路由器的工作负荷。
应理解，本申请实施例对于如何确定第二终端的主机互联网协议地址范围也不做限制，在一些实施例中，可以根据局域网中的本地互联网协议地址和子网掩码，确定第二终端的主机互联网协议地址范围。
S203、根据第二终端的主机范围，第一终端向第二终端发送单播消息，单播消息用于请求在局域网中获取第二终端的信息。
在本步骤中，当第一终端在局域网中确定第二终端的互联网协议地址范围后，可以根据第二终端的主机互联网协议地址范围，遍历向第二终端发送单播消息，从而获取第二终端的信息。
在一些实施例中，当第二终端接收到单播消息后，可以向第一终端发送反馈消息，该反馈消息中包含有第二终端的信息。随后，第一终端基于反馈消息，更新第一终端可连接的第二终端的列表。
在一些实施例中，第一终端可以显示可连接的第二终端的列表，以便用户选择建立远程拍摄连接的第二终端。当用户选择出合适的第二终端后，可以向第一终端输入指示消息，以便第一终端与选择出的第二终端建立远程拍摄连接。
其中，远程拍摄连接用于将第一终端的拍摄画面共享给第二终端并通过第二终端向第一终端发送拍摄指令。
在另一些实施例中，若预设时间内未接收到第二终端发送的反馈消息，则第一终端可以确定发送单播消息失败，此时，第一终端可以根据第一终端的本地互联网协议地址生成二维码，并显示该二维码。用户可以直接使用第二终端扫描该二维码，从而使第二终端获取第一终端的本地互联网协议地址，以便建立第一终端与第二终端之间的远程拍摄连接。需要说明的是，本申请实施例对于预设时间的长短不做限制，在一些实施例中，预设时间可以为5秒、10秒、30秒等。
本公开中，在组播异常时，可以通过发送单播消息或者生成二维码扫描的方式直接建立第一终端和第二终端之间的远程拍摄连接，从而提高了建立远程拍摄连接的成功率。
本公开实施例提供的远程拍摄方法，第一终端首先接收远程拍摄请求，该远程拍摄请求用于指示第一终端搜索第二终端，第二终端用于向第一终端发送拍摄指令。随后，若第一终端接入的无线网络或热点对应的局域网的组播异常，则第一终端在局域网中确定第二终端的主机互联网协议地址范围。最后，根据第二终端的主机互联网协议地址范围，第一终端向第二终端发送单播消息，单播消息用于请求在局域网中获取第二终端的信息。通过该方式，在组播异常时，可以通过在局域网中确定第二终端的主机互联网协议地址范围，从而遍历向局域网中的第二终端发送单播消息，可以保证用于拍摄的第一终端和用于远程控制的第二终端建立远程拍摄连接。
在上述实施例的基础上，若第一终端和第二终端为特定的目标操作系统，则可以直接使用该目标操作系统的多点连接功能搜索提供服务的第二终端。图3为本公开实施例提供的另一种远程拍摄方法的流程示意图，如图3所示，该远程拍摄方法包括：
S301、在第一终端开启无线网络或热点功能后，第一终端通过目标操作系统的多点连接功能搜索提供服务的第二终端。
其中，无线网络或热点功能可以为WiFi功能、热点功能等。
应理解，本公开实施例对于目标操作系统不做限制，例如IOS系统、安卓系统等。示例性的，若目标操作系统为IOS系统，则可以通过多点连接功能直接使用WiFi Direct的方式搜索第二终端，只需打开WiFi功能，无需连接WiFi，可以更为快捷的建立第一终端和第二终端之间的远程拍摄连接。
S302、第一终端接收第二终端发送的第二终端的信息。
其中，第二终端的信息承载于单播消息、组播消息或多点连接功能的附加消息中。
S303、第一终端根据第二终端的信息，更新第一终端可连接的第二终端的列表。
在一些实施例中，第一终端不但可以使用发送组播信息、单播消息的方式搜索第二终端，同时还可以使用目标操作系统的多点连接功能搜索第二终端。相应的，在更新第一终端可连接的第二终端的列表时为了进行区分，第一终端可连接的第二终端的列表中包含有指示信息，指示信息用于指示第二终端的操作系统。
示例性的，上述第一终端可连接的第二终端的列表中的指示信息可以指示各个第二终端的维度的信息，可以包括第二终端的名称、操作系统的名称。若操作系统为IOS系统，则上述指示信息可以进一步包含IOS设备的名称。
其中，操作系统的名称可以指示操作系统的类型信息。示例性的，若操作系统的名称中特定位置的字符为1，则该操作系统可以为IOS系统，若操作系统的名称中特定位置的字符为2，则该操作系统可以为安卓系统。
在上述实施例的基础上，下面提供一种完成的远程拍摄方法。图4为本公开实施例提供的再一种远程拍摄方法的流程示意图，如图4所示，该远程拍摄方法包括：
S401、接收远程拍摄请求，远程拍摄请求用于指示第一终端搜索第二终端，第二终端用于向第一终端发送拍摄指令。
S402、确定无线网络或热点是否打开。
若是，则执行步骤S404，若否，则执行步骤S403。
S403、在第一终端的显示界面上显示提示信息。
S404、确定第一终端是否为目标操作系统。
若是，则执行步骤S405，若否，则执行步骤S407。
S405、通过目标操作系统的多点连接功能搜索提供服务的第二终端。
S406、确定是否接收到第二终端的反馈信息。
若是，则执行步骤S416，若否，则执行步骤S407。
S407、确定是否接入无线网络或热点。
若是，则执行步骤S408，若否，则执行步骤S403。
S408、加入组播组，开始监听。
S409、确定组播是否异常。
若是，则执行步骤S412，若否，则执行步骤S410。
S410、发送组播消息。
S411、是否接收到第二终端的反馈信息。
若是，则执行步骤S416，若否，则执行步骤S412。
S412、在局域网中确定第二终端的主机互联网协议地址范围。
S413、根据第二终端的主机互联网协议地址范围，向第二终端发送单播消息。
S414、是否接收到第二终端的反馈信息。

S415、根据第一终端的本地互联网协议地址生成二维码。
在步骤S415之后，执行步骤S418。
S416、根据第二终端的信息，更新第一终端可连接的第二终端的列表。
S417、接收用户输入的指示信息，该指示信息用于指示从第二终端的列表中选择的第二终端。
S418、建立第一终端和第二终端之间的远程拍摄连接。
本公开实施例提供的远程拍摄方法，第一终端首先接收远程拍摄请求，该远程拍摄请求用于指示第一终端搜索第二终端，第二终端用于向第一终端发送拍摄指令。随后，若第一终端接入的无线网络或热点对应的局域网的组播异常，则第一终端在局域网中确定第二终端的主机互联网协议地址范围。最后，根据第二终端的主机互联网协议地址范围，第一终端向第二终端发送单播消息，单播消息用于请求在局域网中获取第二终端的信息。通过该方式，在组播异常时，可以通过在局域网中确定第二终端的主机互联网协议地址范围，从而遍历向局域网中的第二终端发送单播消息，可以保证用于拍摄的第一终端和用于远程控制的第二终端建立远程拍摄连接。
