需要说明的是，虽然在装置示意图中进行了功能模块划分，在流程图中示出了逻辑顺序，但是在某些情况下，可以以不同于装置中的模块划分，或流程图中的顺序执行所示出或描述的步骤。说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。
一般的终端视频通信只能将本端一个摄像头采集的视频数据传递给对端，不能满足用户基于终端前后摄像头的通信需求，用户体验较差。例如，当今社会大部分家长都很忙，没时间辅导孩子作业，以及和孩子交流、沟通越来越少，一般的终端视频通信模式无法让家长一边通过传递过来的前置摄像头窗口看到小孩的动态，一边通过后置摄像头对孩子的 作业进行辅导。
基于此，本申请实施例提供了视频通信方法、终端及存储介质，能够实现同时利用终端的前置摄像头和后置摄像头进行视频通信，从而提升用户体验。例如，在一个教学示例场景中，可以将本端(如孩子所持终端)前置和后置摄像头获取的视频数据一起传送给对端(如家长所持终端)，对端不仅可以看到本端的前置摄像头获取的图像，进行视频聊天，还可以看到本端后置摄像头获取的图像内容(书本、文件等)，从而有利于进行在线教学辅导。
需要说明的是，下列多种实施例中，第一终端和第二终端均可以为移动终端设备，也可以为非移动终端设备。移动终端设备可以为手机、平板电脑、笔记本电脑、掌上电脑、车载终端设备、可穿戴设备、超级移动个人计算机、上网本或者个人数字助理等；非移动终端设备可以为个人计算机、电视机、柜员机或者自助机等。视频通信可以是任何通信内容包含视频数据的视频通信，例如，可以是通信内容包含视频、语音等数据通信的视频通话，也可以是通信内容包含视频、语音、文件等数据通信的视频通信，也可以是通信内容仅包含视频数据的视频通信。第一终端与第二终端可以是直接通信连接，如通过WiFi连接、蓝牙进行通信连接；也可以是通过第三方网络通信连接，如通过移动互联网(2G/3G/4G/5G等)通信连接。
第一终端或第二终端的输入装置可以是触摸屏、鼠标、键盘等常见输入装置，也可以是视觉传感器、声音传感器等智能输入装置。对应地，可通过解析用户对触摸屏、鼠标、键盘等输入装置的操作，得到相应的用户操作指令；也可利用图像识别、语音识别等算法解析图像、声音等信息以得到相应的用户操作指令。用户操作可以是对第一终端显示界面触发入口的触摸、点击操作。
第一方面，本申请实施例提供用于第一终端的视频通信方法。
在一些实施例中，第一终端具有第一前置摄像头、第一后置摄像头、第一数据采集模块、第一数据传输模块，第一终端与第二终端通信连接。其中，第一前置摄像头可以是单个摄像头，也可以是多个摄像头组成的摄像头组；第一后置摄像头可以是单个摄像头，也可以是多个摄像头组成的摄像头组。第一数据采集模块主要负责第一终端的数据采集，包括第一前置摄像头、第一后置摄像头的视频数据采集，第一旋转角度信息采集等。第一数据传输模块主要负责与第二终端建立通信连接，将第一数据采集模块采集的数据传输给第二终端，并接收来自第二终端的数据信息。
示例1A
参照图1，示例1A的视频通信方法包括步骤：
S1110，采集第一前置摄像头和第一后置摄像头的视频数据；
S1120，将第一前置摄像头和第一后置摄像头的视频数据传输给第二终端。
在一些实施例中，可以在第一终端和第二终端建立通信链路，开始视频通信时，直接触发执行步骤S1110和S1120；也可以是单摄像头视频通信过程中，获取第一用户操作指令，根据第一用户操作指令触发执行步骤S1110和S1120。在一实施例中，可以在第一终端的显示界面上提供通信触发入口(如选择按钮、选择框等)，并通过第一终端的输入装置获取用户操作，通过解析用户操作得到第一用户操作指令，并根据第一用户操作指令触发执行步骤S1110和S1120。步骤S1110中，可以利用第一数据采集模块采集第一前置摄像头和第一后置摄像头的视频数据；步骤S1120中，可以利用第一数据传输模块将第一前 置摄像头和第一后置摄像头的视频数据传输给第二终端。
根据本申请实施例提供的方案，能够实现同时利用终端的前置摄像头和后置摄像头进行视频通信，从而提升了用户体验。
示例1B
参照图2，相对于示例1A，示例1B的视频通信方法还包括步骤：
S1210，接收来自第二终端的摄像头调节指令；
S1220，根据摄像头调节指令调节第一前置摄像头或第一后置摄像头的摄像头参数；摄像头参数包括下列参数的至少一种：焦距、光圈、补光等。
在一些实施例中，在第一终端和第二终端进行视频通信过程中，接收来自第二终端的摄像头调节指令，就可以对第一终端的前置和/或后置摄像头的摄像头参数进行调节，使得第二终端显示的内容更加清晰或显示更多内容。步骤S1210中，可以利用第一数据传输模块接收来自第二终端的摄像头调节指令。
例如，在一个家庭远程教学应用场景中，第一终端为孩子手持的手机，第二终端为家长手持的手机，家长可以通过第一终端传递过来的第一前置摄像头视频数据看到小孩的动态，同时通过第一后置摄像头查看孩子的作业。当家长通过发现作业图像不清晰时，可以通过第二终端输入想要的清晰度数值，以配置第一后置摄像头的相关参数(光圈、焦距等)；或者可以通过第二终端显示界面上提供的滑动条/调节旋钮调节调节第一后置摄像头的相关参数(光圈、焦距等)。第二终端将家长输入的清晰度或操作转换为摄像头调节指令，并将摄像头调节指令传送给第一终端；第一终端接收摄像头调节指令，并通过调用第一后置摄像头的相关接口，改变摄像头的相关参数(光圈、焦距等)，从而改变第二终端显示图像的清晰度，进而使得家长可看清作业图像。
在一些实施例中，摄像头参数包括下列参数的至少一种：焦距、光圈、补光等。用户可根据实际需要设置不同的摄像头参数。例如，用户可通过调节焦距和/或光圈参数实现调节第一前置摄像头或第二前置摄像头所采集图像的清晰度，可通过调节补光参数实现调节第一前置摄像头或第二前置摄像头补光的强度。
