[0037] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0038] Figure 1 A flowchart of a video communication method 100 according to an embodiment of the present disclosure is shown. The video call method is applied to a queuing machine. Specifically, the method 100 includes:

[0039] S101. When the calling device and the called device establish a camera connection, the calling device sends multiple sets of video data captured by multiple cameras corresponding to the called device and the location information of multiple cameras corresponding to the called device to the calling device, wherein one camera corresponds to capturing one set of video data.

[0040] In this step, the calling device initiates the camera connection, and the called device receives the camera connection request. Once the calling and called devices establish a camera connection, they can transmit video data to each other. The called device can have multiple cameras, each used to capture video data from different angles and positions.

[0041] In some embodiments, before sending multiple sets of video data captured by multiple cameras corresponding to the called device and the location information of the multiple cameras corresponding to the called device to the calling device when a camera connection is established between the calling device and the called device, the method further includes:

[0042] The traffic route generated by the calling device initiating a call to the called device through the core network equipment is sent to the IVVR, so that the IVVR initiates video negotiation with the calling device.

[0043] If the IVVR successfully negotiates video with the calling device, a camera connection request sent by the IVVR is received. The camera connection request carries identification information of multiple cameras corresponding to the called device.

[0044] Send the camera connection request to the media gateway device;

[0045] The media gateway device receives multiple sets of video data captured by multiple cameras corresponding to the called device, obtained from the video surveillance platform, sent by the media gateway device based on the camera connection request.

[0046] In the above embodiments, the calling device can be understood as a terminal device such as a mobile phone. The user can dial a dedicated number corresponding to multiple cameras of the called device using their mobile phone; after receiving the call request from the calling device, the core network device generates a traffic route and sends the traffic route to the queuing machine; the queuing machine then sends the traffic route to the interactive voice and video response (Interactive Voice and Video Response) system. The queuing system (IVVR) sends a waiting control command. Based on the waiting control command sent by the queuing machine, the IVVR queries the service interface for the binding relationship between the multiple cameras corresponding to the called device and the number information of the calling device. If the IVVR confirms that the number information corresponding to the calling device and the multiple cameras corresponding to the called device are bound together, it initiates video negotiation with the calling device. If the video negotiation between the IVVR and the calling device is successful, the queuing machine receives a camera connection request sent by the IVVR, which carries the identification information of the multiple cameras corresponding to the called device. The queuing machine sends a camera connection request to the media gateway device. The media gateway device sends a camera connection request to the video surveillance platform. Based on the identification information of the multiple cameras corresponding to the called device in the camera connection request, the video surveillance platform returns multiple sets of video data captured by the multiple cameras corresponding to the called device to the media gateway device. The media gateway device returns multiple sets of video data captured by the multiple cameras corresponding to the called device to the queuing machine. The queuing machine returns multiple sets of video data captured by the multiple cameras corresponding to the called device to the calling device for user viewing.

[0047] In this embodiment, managing the initial call and generating call routes through the core network equipment ensures the consistency and standardization of the call process. The IVVR system can provide interactive voice and video responses, handling user requests more intelligently and improving the user experience. Integrating audio and video communication functions within the same system allows users to not only conduct voice calls but also switch to or add video call functionality as needed. Utilizing the IVVR system's video negotiation mechanism, real-time video from the called device's camera can be obtained, making it particularly suitable for scenarios such as remote monitoring and technical support.

[0048] In some embodiments, the IVVR initiates video negotiation with the calling device when it confirms that the number information corresponding to the calling device is bound to multiple cameras corresponding to the called device.

[0049] In the above embodiments, if the IVVR confirms that the number information corresponding to the calling device is bound to multiple cameras corresponding to the called device, it initiates video negotiation with the calling device. If the IVVR confirms that the number information corresponding to the calling device is not bound to the multiple cameras corresponding to the called device, it instructs the queuing machine to play a video or voice message indicating that the camera connection is invalid to the calling device.

[0050] In this embodiment, by verifying the binding relationship between the calling device's number information and the called device's camera, it ensures that only authorized users can access the footage from a specific camera. If there is no binding relationship, access is cut off, thereby preventing potential security vulnerabilities or malicious actors from obtaining sensitive video data. Furthermore, if the calling device lacks authorization, the system can immediately display an invalid connection notification through a queuing system, allowing users to promptly identify the problem without having to wait a long time for the operation result.

[0051] In some embodiments, before receiving the camera connection request sent by the IVVR after the IVVR has successfully negotiated video with the calling device, the method further includes:

[0052] Receive the video switching request sent by the IVVR;

[0053] Based on the video switching request, a video negotiation request is sent to the calling device through the core network device;

[0054] The core network equipment receives a video negotiation success message sent by the calling device based on the video negotiation request.

[0055] Send the video negotiation success message to the IVVR.

[0056] In the above embodiments, the queuing machine receives a video switching request sent by the IVVR, and based on the video switching request, sends a video negotiation request to the calling device through the core network equipment; based on the video negotiation request, the calling device switches from the previous audio call to a video call, and sends a video negotiation success message to the queuing machine through the core network equipment.

[0057] In this embodiment, the orderly management of core network equipment and queuing machines ensures the security and controllability of the entire handover process, preventing unauthorized access and operation.

[0058] S102. Receive control command information for the multiple cameras sent by the calling device through the DC channel of the core network device, wherein the control command information is determined by the calling device based on monitoring requirement information, identifying the target object in the multiple sets of video data, and the position information of the target object in the multiple sets of video data and the position information of the multiple cameras.

[0059] In this step, after receiving multiple sets of video data from multiple cameras corresponding to the called device, the calling device can first perform preliminary processing on the video data, such as noise reduction, correction, and format conversion, to facilitate subsequent analysis. Then, geometric and color calibration is performed on the pre-processed video data to reduce perspective differences. Based on monitoring needs, the calling device can use pre-trained computer vision algorithms to detect and identify target objects in the calibrated video data and obtain the 2D coordinates of the target objects in each set of video image data. Using the intrinsic parameters (focal length, optical center, etc.) and extrinsic parameters (rotation matrix and translation vector) of each camera, these 2D image coordinates of the target objects are converted into 3D coordinates. The future motion trajectory of the target objects is predicted based on the 3D coordinates of the target objects in different video data. Based on the future motion trajectory of the target objects and the position of each camera, the required rotation angle of each camera is calculated.

[0060] For example, the calling device can be the mobile phone of the monitoring personnel, and the multiple cameras corresponding to the called device can be multiple cameras installed in different locations and angles in a forest. When the monitoring personnel discover a forest fire in the video, the calling device can use a pre-trained computer vision algorithm to detect and identify the flame in multiple sets of calibrated video data, and obtain the 2D coordinates of the flame in each set of video image data; using the intrinsic parameters (focal length, optical center, etc.) and extrinsic parameters (rotation matrix and translation vector) of each camera, these 2D image coordinates of the flame are converted into 3D coordinates; the spread of the target object is predicted based on the 3D coordinates of the flame in different video data; based on the spread of the flame and the position of each camera, the angle that each camera needs to rotate is calculated, thereby better monitoring the fire situation, taking timely emergency measures, and controlling the spread of the fire.

[0061] S103. The control command information is sent to the called device through interactive language and video response (IVVR) so that the called device can control the multiple cameras corresponding to the called device based on the control command information.

[0062] In this step, we will continue to illustrate with the example of step S102, where the surveillance camera performs an angle change based on instruction information (such as turning 30 degrees to the left).

[0063] S104. Receive the indication information sent by the called device via IVVR;

[0064] S105. The instruction information is sent to the calling device through the DC channel so that the calling device processes the multiple sets of video data based on the instruction information.

[0065] The queuing system can also receive indication information sent by the called device via IVVR. Let's continue with the example steps above. The indication information can be understood as overlay information. If a forest fire is detected by a surveillance camera, an alarm message can be output. The queuing system sends this alarm message to the calling device via the DC channel, overlaying it onto the video data showing a fire as viewed by the calling device, thus alerting the monitoring personnel.

[0066] In this embodiment, based on existing video calls, transmitting instruction information through the DC channel can provide the calling device with more intuitive and interactive support, thereby improving communication efficiency and problem-solving accuracy.

[0067] See Figure 2 , Figure 2The second flowchart illustrates the video call method. The calling device can be understood as a mobile phone or other terminal device. The user can dial the dedicated number corresponding to multiple cameras on the called device using their mobile phone. Upon receiving the call request from the calling device, the core network device generates a traffic route and sends it to the queuing machine of the video surveillance platform. The queuing machine sends a waiting control command to the Interactive Voice and Video Response (IVVR). Based on the waiting control command, the IVVR queries the service interface for the binding relationship between the multiple cameras on the called device and the calling device's number information. If the IVVR confirms the binding relationship between the calling device's number information and the cameras on the called device, it sends a video switching request to the queuing machine. The queuing machine receives the video switching request from the IVVR and, based on this request, sends a video negotiation request to the calling device through the core network device. Based on this video negotiation request, the calling device switches from an audio call to a video call and sends a successful video negotiation message to the queuing machine through the core network device. The queuing machine notifies the IVVR of the successful video switching. The IVVR obtains the identification information of the multiple cameras corresponding to the called device from the service interface and sends a camera connection request to the queuing machine. The request includes a camera connection request carrying identification information of multiple cameras corresponding to the called device; the queuing machine sends a camera connection request to the media gateway device; the media gateway device sends a camera connection request to the video surveillance platform; based on the identification information of the multiple cameras corresponding to the called device in the camera connection request, the video surveillance platform returns multiple sets of video data captured by the multiple cameras corresponding to the called device to the media gateway device; the media gateway device returns multiple sets of video data captured by the multiple cameras corresponding to the called device to the queuing machine; the queuing machine returns multiple sets of video data captured by the multiple cameras corresponding to the called device to the calling device for user viewing; the calling device can send control command information for the multiple cameras to the called device through the DC channel of the core network device; the called device can send indication information (such as alarm information) to the calling device through the DC channel of the core network device.

[0068] According to embodiments of this disclosure, when a camera connection is established between a calling device and a called device, the calling device sends multiple sets of video data captured by multiple cameras corresponding to the called device, along with location information of the multiple cameras corresponding to the called device, wherein each camera captures one set of video data. The calling device receives control command information for the multiple cameras sent through the DC channel of the core network device. This control command information is determined by the calling device based on monitoring requirements, identifying a target object in the multiple sets of video data, and then using the location information of the target object in the multiple sets of video data and the location information of the multiple cameras. The control command information is then sent to the called device via interactive language and video response (IVVR) to enable the called device to control the multiple cameras corresponding to the called device based on the control command information. In this embodiment, the calling device can not only view video data captured by multiple cameras, but also obtain accurate control command information based on monitoring requirements, combining the video data from multiple cameras and the position information of each camera. This control command information is then sent to the called device via the DC channel, enabling the called device to perform real-time and precise control over its corresponding multiple cameras. The called device can also send instruction information to the calling device based on the monitoring screen information, allowing the calling device to process the video data according to the instruction information. This method increases the interactivity of video communication and improves its efficiency.
