Description

Technical Field

[0001] The present invention relates to the technical field of video surveillance display switching, and particularly relates to a method for channel group switching of real-time preview of video surveillance devices. Background Art

[0002] In the field of video image surveillance, in order to improve the surveillance efficiency and coverage, the display screen is usually divided into multiple windows, and each window is used to display video image data from different data sources. This multi-window display technology enables the surveillance personnel to monitor multiple scenarios simultaneously, greatly improving the comprehensiveness and real-time nature of surveillance. However, with the diversification and complexity of surveillance requirements, the requirement for the flexibility of the picture display is also getting higher and higher.

[0003] During the picture display process, it is often necessary to switch the segmentation mode according to the surveillance requirements, that is, to switch from one segmentation layout to another. For example, in some cases, the surveillance personnel may need to observe a specific area more carefully, and at this time, the display screen needs to be divided into more small windows to accommodate more surveillance pictures; in other cases, in order to obtain a broader view, the surveillance personnel may hope to reduce the number of windows and divide the display screen into fewer large windows. Moreover, the large-window segmentation mode also makes it impossible to display all surveillance pictures on the same display screen, and it is necessary to switch to view.

[0004] The existing segmentation mode switching methods mainly rely on manual operations. The surveillance personnel need to manually select and switch to the required segmentation mode through the control panel or software interface. However, in actual surveillance work, the surveillance personnel often face heavy surveillance tasks, need to constantly pay attention to the dynamic changes of multiple surveillance pictures, and make timely responses. Therefore, the existing manual switching method is relatively single and inefficient, and cannot meet the needs of the surveillance personnel to quickly jump to the required key pictures. Moreover, the existing manual switching method may also cause the surveillance personnel to be unable to quickly obtain key information in case of emergency, thus delaying the best disposal time. Summary of the Invention

[0005] The present invention aims to provide a method for channel group switching of real-time preview of video surveillance devices to solve the technical problems of the existing manual switching of surveillance display pictures being relatively single and inefficient.

[0006] To achieve the above object, the present invention adopts the following technical solution: A method for channel group switching of real-time preview of video surveillance devices, which acquires the user-defined initial segmentation mode and the corresponding initial channel combination, acquires the video data of multiple channels, and displays the video data of the initial channel combination corresponding to the initial segmentation mode;

[0007] Monitor the video channel switching instruction, and according to the video channel switching instruction, switch the currently displayed split mode or channel combination. The video channel switching instruction includes an automatic switching instruction and a manual switching instruction;

[0008] The automatic switching instruction is to automatically trigger the switching of the currently displayed video channel according to specific conditions, and switch from the current display to the split mode and channel combination customized by the user;

[0009] The manual switching instruction is to trigger the display interface manually by the user, and according to the click trigger condition, switch from the current display to the split mode or channel combination of the target display.

[0010] The principle and advantages of this solution are as follows: By combining the two methods of automatic switching and manual switching, this solution realizes the optimization of the channel grouping switching method for real-time preview of video monitoring devices; when specific conditions are met, the system will automatically switch to the split mode and channel combination preset by the user; while the manual switching instruction is issued by the user by clicking the trigger interface, and according to the user's click operation, the system can switch to the split mode or channel combination of the target display.

[0011] This solution combines two methods of automatic switching and manual switching, making the switching of the monitoring screen more flexible and diverse. Users can choose the most suitable switching method according to actual needs, thus improving the monitoring efficiency. Through the automatic switching instruction, the system can automatically switch the monitoring screen under specific conditions without manual operation by the user. This not only saves the user's time, but also improves the accuracy and efficiency of monitoring switching. Under specific conditions (such as moving object detection), the system can automatically identify and trigger the video channel switching instruction, and switch to the single-screen mode of the relevant video channel. This enables the monitoring personnel to clearly see the specific situation of the moving object and discover and handle abnormal situations in time. Users can customize multiple split modes and channel combinations according to different monitoring needs and flexibly switch through the system. This enables this solution to adapt to diverse monitoring scenarios and needs.

[0012] Preferably, as an improvement, the manual switching instruction includes double-click switching, and the double-click switching is to double-click any video channel picture on the currently displayed interface to switch the currently displayed content;

[0013] When the double-click switching condition is triggered, if the currently double-clicked display interface is not in the single-screen mode, and switch the display to the single-screen mode of the clicked video channel; if the currently double-clicked display interface is in the single-screen mode, then switch the display to the memory split mode including the clicked video channel, and the memory split mode is the non-single-screen mode after the last manual switching instruction switches the display.

[0014] The beneficial effects of this improvement are as follows: In the scenario of multi-channel preview, each monitoring screen is often relatively small. When a user discovers an abnormality in the monitoring of a certain channel in real time and wishes to zoom in for a closer look, the traditional switching method may require the user to perform complex menu or button operations. After introducing the double-click zoom-in / zoom-out function, the user only needs to simply double-click on any video channel screen on the current display interface to quickly switch to the single-screen mode of that channel for zoomed viewing. This improvement greatly enhances the operational convenience of the user, enabling the user to respond and handle abnormal situations more quickly.

[0015] After introducing the double-click switching function, in order to ensure the predictability of the switching result and the consistency of the operation logic, this solution also discloses the technical features of the judgment of the single-screen mode and the setting of the memory segmentation mode. It ensures that during the continuous switching operation process by the user, whether it is automatic switching, manual switching, or double-click zoom-in / zoom-out, the switching logic can maintain consistency and predictability, avoiding interruption and confusion of the switching methods.

[0016] Since the segmentation mode of the screen and the channel settings can be randomly combined, after introducing the double-click switching function, the system needs to be able to flexibly handle various switching requests. This improved solution defines the switching principle by designing a reasonable management plan, ensuring that the system can maintain a high degree of flexibility and adaptability in the face of complex and changing monitoring requirements.

[0017] Preferably, as an improvement, the channel grouping switching method further includes obtaining the channel grouping situation of each video channel under each segmentation mode defined by the user. The channel grouping situation includes the combination method of the video channels under this segmentation mode, the display positions of each video channel in this channel combination under this segmentation mode, and the sequence of each channel combination;

[0018] The manual switching instruction further includes single-click switching, and the single-click switching is to single-click the segmentation mode button on the display interface to switch the current displayed content;

[0019] When the single-click switching condition is triggered, if the segmentation mode button triggered by the single click is different from the currently displayed segmentation mode, then switch the display to the first channel combination of the channel combination sequence corresponding to the clicked segmentation mode button; if the segmentation mode button triggered by the single click is the same as the currently displayed segmentation mode, then switch to the next channel combination according to the channel combination sequence under the current segmentation mode;

[0020] If the segmentation mode after the current single-click switching is a non-single-screen mode, then update and record the switched segmentation mode as the memory segmentation mode.

[0021] The beneficial effects of this improvement are as follows: By introducing the single - click switching function, users can simply switch the current displayed content by single - clicking the split - mode button on the display interface. This operation method is intuitive and easy to understand, greatly reducing the user's learning cost. At the same time, the distinction between the number of clicks and the click position (double - click and single - click) enables users to perform the required switching operation more accurately, avoiding the possibility of misoperation.

[0022] By setting the channel combination sequence, this improved solution simplifies the number of buttons for manual switching. Users do not need to frequently switch between multiple split - modes and channel combinations. They only need to single - click the split - mode button to sequentially switch within the preset channel combination sequence. This not only improves the switching efficiency but also saves display space, making the display interface more concise and clear.

[0023] In the single - click switching function, if the split - mode button triggered by a single - click is different from the current displayed split - mode, the display is switched to the first channel combination of the channel combination sequence corresponding to the clicked split - mode button. This design enables users to quickly switch to the required split - mode and channel combination, improving the accuracy and efficiency of switching. At the same time, if the split - mode after the current single - click switch is not the single - screen mode, the updated record of the switched split - mode is set as the memory split - mode. This function ensures that when the automatic switch interrupts the current manual switching operation process, users can quickly return to the previous manual operation interface through a simple operation without having to repeat the manual switching operation, thus maintaining the continuity of the switching operation and the consistency of the user experience.

[0024] Since users can customize the channel grouping of each video channel under each split - mode, including combination methods, display positions, and channel combination sequences, etc., this improved solution endows the system with high flexibility and scalability. Users can adjust the channel grouping and switching sequence according to actual needs to adapt to different monitoring scenarios and requirements. This design enables the system to better meet the personalized needs of users and improves the practicality and application value of the system.

[0025] Preferably, as an improvement, the automatic switching instructions are one or more. When there are multiple automatic switching instructions, the triggering conditions of each automatic switching instruction are different; the target displays switched by different automatic switching instructions are different display contents or the same display content.

[0026] The beneficial effects of this improvement are as follows: By allowing multiple automatic switching instructions to exist, and the triggering conditions of each instruction being different, this design greatly enhances the flexibility and adaptability of the system. Different automatic switching instructions can be configured according to specific monitoring requirements and scenarios, such as switching based on time intervals, event triggers, or specific conditions (such as specific time periods, personnel activity detection, etc.). This diversity enables the system to meet multiple monitoring requirements simultaneously, improving the efficiency and accuracy of monitoring. At the same time, the target display content switched by different automatic switching instructions can be the same or different, further increasing the flexibility and practicality of the system.

[0027] Preferably, as an improvement, when clicking to switch the channel combinations of the same splitting mode, the channel combinations of this splitting mode are displayed in sequence loop.

[0028] The beneficial effects of this improvement are as follows: When the currently displayed channel combination is the last one in this sequence, switching to the same splitting mode will cause the display to jump to the first channel combination in this sequence; enabling continuous switching operations for monitoring personnel.

[0029] Preferably, as an improvement, the combination method of video channels in the splitting mode is to specify the video channels corresponding to the number of frames in this splitting mode as a group, and different channel combinations can include the same video channels.

[0030] The beneficial effects of this improvement are as follows: By allowing the video channels corresponding to the number of frames in the specified splitting mode to be a group, and different channel combinations can include the same video channels, this design provides great flexibility and convenience. Users can arbitrarily match and combine video channels according to actual monitoring requirements and scenarios to form different monitoring screens. This flexibility enables the system to better adapt to various complex monitoring environments, improving the pertinence and accuracy of monitoring. At the same time, allowing different channel combinations to include the same video channels also enables users to perform multi-combination cooperative monitoring on the same video channel in the same splitting mode, further enhancing the monitoring ability and practicality of the system.

[0035] The following is a further detailed description through specific embodiments:

[0036] Embodiment

[0037] Basically as shown in the attached Figure 1 As shown, a method for channel group switching in real-time preview of a video surveillance device includes:

[0038] Obtain the types of splitting modes defined by the user. As shown in the attached Figure 2 As shown, the splitting modes include single-screen, four-screen, nine-screen, three-screen, etc.; and obtain the channel grouping situation of each video channel under each splitting mode defined by the user. The channel grouping situation includes the combination method of video channels in this splitting mode, the display positions of each video channel in this channel combination under this splitting mode, and the sequence of each channel combination.

[0039] The combination method is to specify the video channels corresponding to the number of screens in this splitting mode as a group, and multiple combination methods can be set according to monitoring requirements.

[0040] Obtain the initial splitting mode defined by the user and the corresponding initial channel combination, obtain the video data of multiple channels, and display the video data of the initial channel combination corresponding to the initial splitting mode.

[0041] Monitor video channel switching instructions. According to the video channel switching instructions, switch the currently displayed splitting mode or channel combination. The video channel switching instructions include automatic switching instructions and manual switching instructions. The automatic switching instruction is to automatically trigger the switching of the currently displayed video channels according to specific conditions, and switch to a specific splitting mode and channel combination defined by the user. The specific conditions include specific time points, moving object detection, etc. The triggering conditions of this automatic switching instruction can be set according to actual monitoring requirements. According to different specific conditions, multiple different automatic replacement instructions can be set; monitor the automatic switching instructions, and according to the triggered specific conditions, switch the current display to the corresponding splitting mode and channel combination.

[0042] For example, in factory shift change monitoring, in a large factory, in order to supervise whether employees change shifts on time and orderly, and ensure that there are no abnormal situations during the shift change process.

[0043] (1) Automatic switching at specific time points. Set the shift change time points, such as 8:00 am and 4:00 pm, as the triggering conditions for the automatic switching instruction. When the time reaches the set shift change time point, automatically trigger the video channel switching instruction. Switch to the splitting mode that displays the most video channels (such as 16-screen splitting) to show the video surveillance of all key areas. In this mode, the monitoring personnel can clearly see whether the employees in each area are changing shifts orderly.

[0044] (2) Automatic switching for moving object detection. During a preset time period (such as within half an hour before and after shift change), the moving object detection function is enabled. When a moving object (such as an employee, a vehicle, etc.) appears in the monitoring screen, the system automatically identifies and triggers a video channel switching instruction. It switches to the single-screen mode of this video channel so that the monitoring personnel can clearly see the specific situation of the moving object. This helps the monitoring personnel to promptly discover and handle abnormal situations, such as employees not arriving at the designated area on time, illegal intrusion, etc.

[0045] Manual switching instructions include single-click switching and double-click switching. Single-click switching is to single-click the split mode button on one side of the display interface to switch the current displayed content. There are multiple split mode buttons, and each split mode supported by this display system has a corresponding split mode button. Double-click switching is to double-click any video channel screen on the current display interface to switch the current displayed content.

[0046] Monitor the single-click switching instruction. If the single-click switching condition is triggered and the split mode button triggered by the single-click is different from the current displayed split mode, then switch the display to the first channel combination in the channel combination sequence corresponding to the split mode of the clicked split mode button. If the current split mode after the manual switch is not the single-screen mode, then update and record the current manually switched split mode as the memory split mode. If the single-click switching condition is triggered and the split mode button triggered by the single-click is the same as the current displayed split mode, then switch to the next channel combination according to the channel combination sequence order in the current split mode. If the current split mode after the manual switch is not the single-screen mode, then update and record the current manually switched split mode as the memory split mode. The channel combinations in the split mode are displayed in a sequence loop.

[0047] Monitor the double-click switching instruction. If the double-click switching condition is triggered and the current display interface double-clicked is not in the single-screen mode, then switch the display to the single-screen mode of the clicked video channel. If the double-click switching condition is triggered and the current display interface double-clicked is in the single-screen mode, then switch the display to the memory split mode containing the clicked video channel.

[0048] As shown in the Figure 3 attachment, if through the manual switching instruction, the current display is in the three-screen mode containing the first channel, the second channel, and the third channel, then the current memory split mode is the three-screen mode. If at this time, the second channel is double-clicked, then the display switches to the single-screen mode of the second channel. If then the video screen of the second channel in the single-screen mode is double-clicked again, then the display switches to the three-screen mode containing the second channel. This is convenient for the monitoring personnel to quickly view and quickly return to the previous manual operation position.

[0049] To clearly illustrate this switching method, the following is a further detailed description:

[0050] As shown in theFigure 4 As shown, the maximum number of channels of the video surveillance system is 8, and the user-defined initial segmentation mode is the three-screen mode. Its corresponding initial channel grouping includes the first channel, the fourth channel, and the fifth channel. The startup screen of the video surveillance system shows a three-screen composed of the first channel, the fourth channel, and the fifth channel, that is, the monitoring display interface is Screen One.

[0051] When the monitoring personnel click the four-screen mode button on one side of the display interface, it triggers a single-click switch of the manual switching instruction, and the display switches to the first channel combination in the four-screen mode, that is, the monitoring display interface is Screen Two.

[0052] When the monitoring personnel click the four-screen mode button on one side of the display interface again, it triggers a single-click switch of the manual switching instruction, and the display switches to the second channel combination in the four-screen mode, that is, the monitoring display interface is Screen Three; at this time, the memory segmentation mode is the four-screen mode.

[0053] When a specific condition defined by the user is met at this time and an automatic switching instruction is triggered, the display switches to the user-defined mode corresponding to this specific condition, such as the nine-screen mode, that is, the monitoring display interface is Screen Four.

[0054] When the monitoring personnel want to zoom in on the video screen of the second channel, they double-click the video screen of the second channel, which triggers a double-click switch of the manual switching instruction, and the display switches to the single-screen mode of the second channel, that is, the monitoring display interface is Screen Five.

[0055] When the monitoring personnel want to return to the previous monitoring operation state, they double-click the video screen of the second channel again, which triggers a double-click switch of the manual switching instruction, and the display switches to the memory segmentation mode including the second channel. At this time, the memory segmentation mode is the four-screen mode, that is, the monitoring display interface is Screen Six.

[0056] The above are only embodiments of the present invention. Specific technical solutions and / or common knowledge such as characteristics well known in the art are not described in detail here. It should be noted that for those skilled in the art, without departing from the technical solution of the present invention, several deformations and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicality of the patent. The protection scope required by this application should be subject to the content of its claims, and the specific implementation manners described in the specification can be used to explain the content of the claims.
