[0061] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0062] Next, we introduce the voice call display method provided by this application, which can be applied to the client, such as Figure 1 As shown, it is a flowchart of Example 1 of the voice call display method provided by this application, which may specifically include the following steps:

[0063] Step S11: Display the surveillance video.

[0064] Step S12: When there is a voice call in the surveillance video, determine the status information of the terminal appearing in the surveillance video, wherein the status information of the terminal includes: location information and call status information.

[0065] In this embodiment, the terminal corresponding to the voice call in the surveillance video will report the location information and call status information. Accordingly, the server can obtain the location information and call status information reported by the terminal and send the location information and call status information reported by the terminal to the client.

[0066] The call status information of the terminal may include, but is not limited to: information indicating that the terminal is in a completed speech state, information indicating that the terminal is in a speech state, or information indicating that the terminal is in a speech listening state.

[0067] In this embodiment, the determination of the status information of the terminal appearing in the surveillance video may include but is not limited to:

[0068] The status information appearing in the monitoring video is determined once every set time.

[0069] The set time can be set as needed and is not limited in this application.

[0070] Step S13: Displaying visual information corresponding to the call status information of each terminal at the monitoring video coordinate corresponding to the location information of the terminal.

[0071] In this embodiment, the call status information of each terminal can be converted into visualization information respectively, and the visualization information corresponding to the call status information can be displayed at the monitoring video coordinates corresponding to the location information of each terminal.

[0072] Visual information may be, but is not limited to, any one or more of text information, symbols, and graphics.

[0073] At the monitoring video coordinates corresponding to the location information of each terminal, visualization information corresponding to its call status information is displayed, so that the call information is presented in the video with a visual effect.

[0074] For example, Figure 2 As shown, if the call information of the completed speech terminal A includes the voice content of "request for support", and the call information of the completed speech terminal B includes the voice content of "there is a situation", the call information of the completed speech terminal A will be converted into visual information, and the call information of the completed speech terminal B will be converted into visual information, and the call information of different completed speech terminals will be displayed on the screen.

[0075] In the present application, by displaying a surveillance video, when there is a voice call in the surveillance video, the status information of the terminal appearing in the surveillance video is determined, wherein the status information of the terminal includes: location information and call status information, and at the surveillance video coordinates corresponding to the location information of each terminal, the visual information corresponding to its call status information is displayed. This allows the voice call to be visually displayed in the video when the video is displayed, making the voice call display more intuitive.

[0076] As another optional embodiment of the present application, refer to Figure 3 , is a flow chart of Example 2 of a voice call display method provided by this application. This embodiment is mainly a detailed solution of the voice call display method described in Example 1 above, such as Figure 3 As shown, the method may include but is not limited to the following steps:

[0077] Step S21: Display the surveillance video.

[0078] Step S22: When there is an individual call in the monitoring video, determine the status information of the terminal appearing in the monitoring video, wherein the status information of the terminal includes: location information and call status information, and the call status information indicates that the call status is completed.

[0079] Step S22 is a specific implementation of step S12 in Example 1.

[0080] Step S23: Display the entire speech content of the individual call at the monitoring video coordinate corresponding to the location information of the terminal.

[0081] Step S24: When the display duration of the entire speech content of the individual call reaches a set duration, the displayed entire speech content of the individual call is deleted.

[0082] Steps S23-S24 are a specific implementation of step S13 in Example 1.

[0083] In this embodiment, the set duration can be set as needed and is not limited in this application.

[0084] If a call is present in the surveillance video and the call status information indicates that the call is complete, the entire call content is displayed at the surveillance video coordinate corresponding to the terminal's location information. This allows for a visual display of the call content within the surveillance video, making the voice call presentation more intuitive. Furthermore, when the display duration of the entire call content reaches a set time, the displayed entire call content is deleted, refreshing the surveillance video display and ensuring the quality of the surveillance video display.

[0085] As another optional embodiment of the present application, refer to Figure 4 , is a flow chart of Example 3 of a voice call display method provided by this application. This embodiment is mainly a detailed solution of the voice call display method described in Example 1 above, such as Figure 4 As shown, the method may include but is not limited to the following steps:

[0090] The visual information of the speaker may be, but is not limited to, any one or more of text information, icons, and symbols.

[0091] For example, Figure 5 As shown, at the monitoring video coordinate corresponding to the location information of the terminal participating in the single group call and obtaining the speaking right, visual information of speaking (such as a speaking display icon) is displayed.

[0092] It should be noted that at the monitoring video coordinates corresponding to the location information of the terminal that participates in a single group call and does not obtain the right to speak, the visual information being monitored can be displayed, such as Figure 5 As shown, the icon that is being monitored is displayed.

[0093] Step S34: Display the conversation content at the monitoring video coordinate corresponding to the location information of the terminal that participated in the single group call and finished speaking.

[0094] Steps S33-S34 are a specific implementation of step S13 in Example 1.

[0095] In the case where there is a single group call in the monitoring video, visual information of the person speaking is displayed at the monitoring video coordinates corresponding to the location information of the terminal participating in the single group call and obtaining the right to speak, and the content of the call is displayed at the monitoring video coordinates corresponding to the location information of the terminal participating in the single group call and having completed the speech. The call information of each terminal in the single group call can be visualized in the monitoring video, making the display of the single group call more intuitive.
