Vuforia⭐一、实现前后摄像头切换、打开关闭闪光灯

    //切换摄像头
    public void SwitchCameraDirection()
    {
        //先停止运行
        CameraDevice.Instance.Stop();
        //取消初始化
        CameraDevice.Instance.Deinit();

        //开启前置摄像头
        CameraDevice.Instance.Init(CameraDevice.CameraDirection.CAMERA_FRONT);
        CameraDevice.Instance.Start();
    }

    //控制闪光灯打开与关闭
    public void FlashTourch(bool state)
    {
        CameraDevice.Instance.SetFlashTorchMode(state);
    }
