[0041] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0042] In order to meet the application requirements of professional mobile terminals for high-definition video supervision of construction projects, the embodiments of the present invention provide a lightweight video supervision method, which can realize the browsing of project video data and quick project screen viewing, focusing on solving the problem of viewing video monitoring at any time, and bringing a new experience of on-site video supervision to managers. You can switch the project site monitoring screen by sliding up and down on the display interface of the mobile terminal, and switch projects by sliding left and right. It also supports video playback, electronic magnification, pan-tilt control, screenshot recording and other functions, which can view the implementation site of the project in real time and improve the management efficiency of the project.

[0043] like Figure 1 As shown, an embodiment of the present invention provides a lightweight video supervision method, including:

[0044] Step 11, obtaining a video of the construction site of the current project;

[0045] Step 12, when a sliding operation in a preset direction on the display interface of the current video is detected, a video switching instruction is generated;

[0046] Step 13: according to the video switching instruction, switch to the next video adjacent to the current video in the video of the construction site of the current project for playing.

[0047] The above-mentioned scheme of the present invention obtains the video of the construction site of the current project; when a sliding operation in a preset direction on the display interface of the current video is detected, a video switching instruction is generated; according to the video switching instruction, the next video adjacent to the current video in the video of the construction site of the current project is switched to be played; the browsing of the on-site video data of the remote monitoring project and the efficient viewing of the pictures can be realized on the mobile terminal, focusing on solving the pain point of the monitoring demand of conveniently watching the monitoring video at any time, and greatly improving the supervision experience of managers.

[0048] In an optional embodiment of the present invention, step 11 may include:

[0049] Step 111, determining the video buffer range;

[0050] Step 112: Buffer the video captured by the camera equipment at the construction site of the current project according to the video buffer range and the preset buffering paths.

[0051] In an optional embodiment of the present invention, the lightweight video monitoring method may further include:

[0052] Step 14: If there are multiple items, buffer the first video of the adjacent items according to the video buffer range.

[0053] In an optional embodiment of the present invention, step 12 may include:

[0054] Step 121, when an upward or downward sliding operation is detected on the display interface of the current video, the sliding distance and the sliding direction are obtained;

[0055] Step 122: If the sliding direction angle is within a preset angle range based on the horizontal line and the sliding distance is greater than a preset distance value, a video switching command is generated.

[0056] Further, step 13 may include: according to the video switching instruction, switching the buffered video from the current video to the next video adjacent to the current video for playback with a dynamic page turning visual effect, and releasing the current video.

[0057] In this embodiment, after the project manager logs into the system, the system displays the first video of a project within the administrator's authority by default. By sliding the screen up and down on the terminal, different surveillance videos under the project can be switched for viewing. Furthermore, the video buffer range is determined according to the project authority. According to the video buffer range, the video captured by the camera equipment at the construction site of the current project is buffered according to the preset buffering number. If there is only one project, the video buffering number of this project will be increased when there is no need to switch projects to increase the smoothness of the user's switching operation. If there are multiple projects, the first video of the adjacent project will be cached to increase the smoothness of the operation when switching projects. At the same time, the video number of this project is reduced, reducing the occupation of computing resources and the consumption of network traffic.

[0058] Furthermore, the number of buffer paths that can be currently buffered can be determined according to the video buffer range, and the video of the online camera can be loaded according to the number of buffer paths that can currently be buffered, and the buffer is loaded in the order of followed video -> ball camera video -> gun camera video.

[0059] When the user slides up or down on the current video, the sliding distance and direction are checked. When the angle is within a certain range and the distance is greater than a preset value, it is judged as a video switching command, and the buffered video is switched to the current video with a dynamic page turning visual effect. At the same time, according to the determined buffer quantity, the video that exceeds the buffer range upward from the current video is released and the video that enters the buffer range downward is started to be buffered to ensure that the system resource usage does not overflow. When the sliding reaches the boundary, the user will be prompted that there are no more videos.

[0060] Furthermore, the order of projects can be sorted in the order of project creation time. When the user reaches the boundary by sliding, the user will be prompted that there are no more projects. When the user slides to the first camera screen and continues to slide down, the user can view the project information of the current project: such as project renderings, the number of various cameras, the number of online and offline cameras, the project notice board, the project leader, etc.

[0061] In an optional embodiment of the present invention, the lightweight video monitoring method may further include:

[0062] Step 14, when a left-right sliding operation on the current display interface is detected, an item switching instruction is generated;

[0063] Step 15: according to the project switching instruction, switch to the next project adjacent to the current project, wherein the projects are sorted according to the creation time.

[0064] In this embodiment, if there are multiple projects within the scope of management authority, you can switch projects by sliding left and right to achieve fast switching management of multiple project monitoring. Specifically, you can quickly switch projects by sliding left and right on the current display interface; of course, you can also quickly switch projects by clicking on the project name in the upper center area of ​​the screen or clicking on the list item. Among them, the list item displays at least one of the following: project cover image, project name, project location, and the number of different types of cameras.

[0065] In an optional embodiment of the present invention, the lightweight video monitoring method may further include:

[0066] Step 16, during the video playback process, at least one of taking a screenshot or recording a video with a problem is recorded to obtain recording information;

[0067] Step 17: Save the recorded information locally and automatically synchronize it to the cloud.

[0068] When this embodiment is implemented, data information can be stored in the cloud and traceable. Problems found during video viewing can be recorded through real-time screenshots and video recordings, saved locally on the terminal and automatically synchronized in the cloud, and a digital archive can be generated and saved in the digital delivery module to ensure that information data is safe and not lost.

[0069] In order to save user traffic consumption, cloud storage adopts asynchronous recording. When the user issues commands such as screenshot, start recording, and end recording in the software, the command is synchronously uploaded to the background. The background calls the hardware interface to perform screenshot and video recording operations, without the need for the user to upload after the recording is completed. At the same time, the delay caused by network delay and other reasons is corrected by timestamp, so that the time difference between asynchronous screenshot and recording and the user terminal is within a controllable range and does not affect the recording effect. At the same time, this mechanism can make the cloud recording work and user recording work at different times, effectively and reasonably allocate computing resources, and prevent recording failures in large concurrent outbreaks.

The user's adjustment time of the camera angle and focal length during the explanation process can be completely consistent with the explanation content, so that other users can hear the explanation content synchronously when watching this video. The system will perform voice recognition on the explanation audio and save the recognition results as video or screenshot attributes, which is convenient for viewing users to quickly browse without spending more time listening to the voice or watching the entire video. The recognized content can be adjusted and modified before uploading.

[0074] The system will perform keyword analysis on the recognized voice, compare it with the keyword library, and automatically detect matching keywords for users to classify, browse and retrieve information.

A lightweight video monitoring system, characterized in that: include: The acquisition module is used to obtain the video of the construction site of the current project; A processing module, configured to generate a video switching instruction when a sliding operation in a preset direction on the display interface of the current video is detected; According to the video switching instruction, switching to the next video adjacent to the current video in the video of the construction site of the current project for playing; Among them, obtain the video of the construction site of the current project, including: Determine a video buffer range; the video buffer range is determined according to the project authority of the project manager; According to the video buffer range, the video collected by the camera equipment at the construction site of the current project is buffered according to the preset buffer path number; when the number of projects is 1, the preset buffer path number of the current project is increased; When the number of items is greater than 1, the first video of the adjacent item is buffered according to the video buffer range, and the number of buffering paths of the current item is reduced; The number of buffering paths is determined according to the video buffering range, and the video of the online camera is loaded according to the number of buffering paths that can be buffered at present, and the buffer is loaded in the order of the watched video, the ball camera video, and the gun camera video; When a sliding operation in a preset direction on the display interface of the current video is detected, a video switching instruction is generated, including: When an upward or downward sliding operation is detected on the display interface of the current video, the sliding distance and sliding direction are obtained; If the sliding direction angle is within a preset angle range based on the horizontal line and the sliding distance is greater than a preset distance value, a video switching command is generated; Wherein, according to the video switching instruction, switching to the next video adjacent to the current video in the video of the construction site of the current project for playing includes: According to the video switching instruction, the buffered video is switched from the current video to the next video adjacent to the current video for playback with a dynamic page turning visual effect, and the current video is released; according to the determined buffering quantity, the video that exceeds the buffering range upward from the current video is released and the video that enters the buffering range downward is started to be buffered; Among them, lightweight video supervision methods also include: When a left-right sliding operation on the current display interface is detected, an item switching instruction is generated; According to the project switching instruction, switch to the next project adjacent to the current project, the projects being sorted according to the creation time; Among them, lightweight video supervision methods also include: During the video playback, at least one of taking a screenshot or recording a video with a problem is recorded to obtain recording information; The recorded information is saved locally and automatically synchronized to the cloud; The cloud storage adopts an asynchronous recording method. When the user issues a screenshot, starts recording, or ends recording command in the software, the command is synchronously uploaded to the background. The background performs screenshot and video recording operations by calling the hardware interface, without the need for the user to upload after recording is completed. At the same time, the delay caused by network delay is corrected by timestamp, so that the time difference between asynchronous screenshot and recording and the user terminal is within a controllable range. Among them, lightweight video supervision methods also include: Describing the recorded information in voice to obtain audio recorded information; Synchronize the audio recording information with a target video obtained by recording the video to obtain a synchronized target video, and save the target video; Automatically associate and structure the video recording with the recorder's explanation. The user can describe the video by voice during the recording or after taking a screenshot. The software uses a microphone to collect the user's audio and synchronize it with the recorded video time. The user's adjustment of the camera angle and focal length during the explanation can completely correspond to the explanation content. The system performs voice recognition on the explanation audio and saves the recognition result as an attribute of the video or screenshot. The recognition content can be adjusted and modified before uploading. Lightweight video supervision methods also include: For problems found during video viewing, after recording or taking screenshots, the recorded information obtained can be quickly shared to the instant messaging system through the sharing function; Or initiate a video conference, notify the target personnel by reading the project personnel list and complete the invocation of the conference system application.
