Description

Background Art

[0002] In the security field, especially in residential areas, factories and other scenarios, it is usually difficult to deploy cluster algorithm services to monitor the behavior of people or security status in real time in each camera screen. In this case, deploying a single algorithm service and traversing all cameras through camera polling is a common solution.

[0003] The existing camera polling method of switching camera groups only according to a certain period has some disadvantages, which may include:

[0004] Inflexibility of fixed cycles: The traditional periodic switching method lacks flexibility and cannot be dynamically adjusted according to actual conditions. For example, during a certain period of time, some cameras may have abnormal conditions or important events, but the polling system cannot flexibly focus on these cameras.

[0005] Waste of resources: In the traditional polling method, even if some camera images have not changed or no important events have occurred, they will be accessed and processed in each polling. This method wastes system resources and computing power.

[0006] Monitoring blind area: Due to the fixed-cycle polling method, some cameras may be in the monitoring blind area at critical moments. For example, if a camera is not in the polling cycle when an important event occurs, the system will miss the monitoring and response to the event.

[0007] Inefficiency: Since all cameras need to be accessed for each polling, the system efficiency may be low, especially when the number of cameras is large. This will increase the response time of the system and may lead to insufficient monitoring data processing capacity.

[0008] In summary, the existing camera polling method of switching camera groups only according to a certain period has some obvious disadvantages, including lack of flexibility, waste of resources, monitoring blind spots, and low efficiency. Therefore, a more intelligent and flexible polling method is needed to improve the performance and efficiency of the monitoring system. Summary of the invention

[0033] Other features, objects and advantages of the present invention will become more apparent from the detailed description of non-limiting embodiments made with reference to the following drawings:

[0034] Figure 1 This is one of the flow charts of a camera monitoring polling switching method according to an embodiment of the present invention;

[0035] Figure 2 The second flowchart of a camera monitoring polling switching method according to an embodiment of the present invention;

[0036] Figure 3 The present invention is a structural framework diagram of an electronic device. DETAILED DESCRIPTION

[0037] To make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0038] like Figure 1 As shown, a camera monitoring polling switching method according to an embodiment of the present invention includes the following steps:

[0039] S1, determine in real time whether there is a target of interest in the monitoring area corresponding to the current monitoring camera;

[0040] S2, if there is an object of interest, continuously monitoring the object of interest through the current monitoring camera;

[0041] If there is no target of interest, after the current monitoring camera monitors for the first preset time period, it switches to the next monitoring camera in a polling order, and uses the next monitoring camera as the current monitoring camera in S1 to execute S1.

[0042] The beneficial effects of a camera monitoring polling switching method provided by the present invention are as follows:

[0043] By determining in real time whether there is a target of interest in the monitoring area corresponding to the current monitoring camera, the targeted nature of monitoring is further improved. That is, instead of blindly polling the camera, it plays an important role in monitoring when there is an anomaly or when designated target monitoring is required.

[0044] Before S1 of this scheme, the following may also be included:

[0045] The polling mode corresponding to the current moment is determined, and when the polling mode is intelligent polling, S1 is executed.

[0046] The polling mode also includes a basic polling model. The basic polling mode can be understood as a traditional polling mode, that is, determining the number of surveillance cameras corresponding to the polling mode and the unique identifier corresponding to each surveillance camera, sorting all unique identifiers, and specifying the polling cycle. According to the polling cycle and the sorting results, polling monitoring is performed. It should be further explained that the monitoring area corresponding to each surveillance camera can be different, or it can be monitoring from multiple angles in the same scene. The monitoring area can be adjusted according to actual needs, which will not be elaborated here.

[0047] It should be further explained that the polling mode corresponding to the current moment is determined as follows:

[0048] The first one is determined by manual adjustment.

[0049] The second method is to determine whether an interested target has appeared in a preset period before the current moment, or whether the time when the interested target appears exceeds the preset time. If so, it is determined that the intelligent polling mode is needed at this time.

[0050] The third method is to determine whether the previous moment was in smart polling mode. If so, further determine whether there is a tag to continue tracking in the smart polling mode corresponding to the previous moment. If so, the smart polling mode is directly adopted at the current moment. If not, further judgment is made through the second method.

[0051] The method for determining whether there is an area of ​​interest is as follows:

[0052] Access the specified number of channels according to the algorithm service capability (the number of channels here refers to the maximum number of cameras that the algorithm service can access at the same time. Figure 2 In the workflow, the intelligent polling mode represents a workflow of one channel, but in fact, multiple channels (i.e., the specified number of channels) are carrying out the process at the same time. The yolov8 detection algorithm is used to detect the target on the camera screen (referring to the camera that has been connected to the polling task, as distinguished from the camera that is not running in the polling task). According to the detection results, it is determined whether there is a target of interest in the monitoring event.

[0053] When there is an interesting target, continuous monitoring is performed until the set monitoring time of the interesting target is reached, the camera is placed in the queue to be polled, and a new camera is obtained for the next round of intelligent polling judgment.

[0054] When there is no target of interest, continuous monitoring is performed until the set monitoring time of no target of interest is reached, and the camera is placed in the queue for polling, and a new camera is obtained for the next round of intelligent polling judgment. (The setting time of whether there is a target of interest can be different, that is, different attention time can be achieved for whether there is a target of interest. Some users pay more attention to scenes without targets of interest, and some users pay more attention to scenes with targets of interest. They can be set according to the actual usage of users).

[0055] When there are at least three surveillance cameras, when there is no target of interest in the surveillance area corresponding to the current surveillance camera and a fixed time has passed, randomly select the surveillance area corresponding to any surveillance camera other than the current surveillance camera to determine whether there is a target of interest. If there is no target of interest in the surveillance area corresponding to any surveillance camera, return to the current surveillance camera and continue to execute S1; if there is a target of interest in the surveillance area corresponding to any surveillance camera, continue to judge the surveillance area corresponding to the current surveillance camera, and at the same time, continue to judge the surveillance area corresponding to the surveillance camera where the target of interest exists until the current surveillance camera monitors for the first preset time, then adjust the unique identifier corresponding to the surveillance camera where the target of interest exists to the head of the polling queue, and continue to monitor the target of interest.

[0056] Alternatively, when there are at least three surveillance cameras, the surveillance area corresponding to the current surveillance camera and the surveillance area corresponding to the next surveillance camera are displayed side by side with the surveillance area corresponding to the current surveillance camera in the polling order, starting from the next surveillance camera corresponding to the current surveillance camera, at fixed intervals, i.e., the two surveillance areas are monitored simultaneously for the presence of targets of interest, wherein the fixed duration is less than the monitoring duration corresponding to normal polling (i.e., in the intelligent polling mode, the interval from switching to the current surveillance camera, when there is no target of interest in the surveillance area corresponding to the current surveillance camera and switching to the next surveillance camera for monitoring). If, during the process of displaying surveillance side by side, there is a target of interest in any surveillance area, when there is no target of interest in the monitoring duration of another surveillance area, then after the corresponding monitoring duration of the other surveillance area is completed, the surveillance is no longer displayed side by side, and the surveillance area with the target of interest is continuously monitored until the monitoring duration of the target of interest reaches the monitoring duration of interest.

[0057] It should be noted that the monitoring duration of interest is longer than the monitoring duration corresponding to normal polling.

[0058] Furthermore, if there is an object of interest, the process of continuously monitoring the object of interest through the current monitoring camera is specifically as follows:

[0059] If there is an object of interest, the current surveillance camera continues to track and shoot the object of interest, and after shooting for a second preset time, switches to the next surveillance camera according to the polling order, and uses the next surveillance camera as the current surveillance camera in S1 to execute S1.

[0060] Furthermore, the method further includes: when the next monitoring camera executes S1, storing the identifier corresponding to the current monitoring camera into the tail of the polling queue of the polling order.

[0061] Furthermore, it also includes: displaying the polling queue of the polling order.

[0062] The effects that the present invention can achieve are:

[0063] Dynamic adjustment and flexibility

[0064] The intelligent polling system can dynamically adjust the frequency and order of camera polling based on actual conditions. For example, the system is able to identify targets of interest and immediately focus attention on the relevant cameras. This flexibility allows the system to monitor specific areas more frequently when needed, thereby improving responsiveness.

[0065] Resource Optimization

[0066] Smart polling can prioritize important or changing images based on changes in camera image content, while reducing access to static images or images with no important events. This on-demand processing method can significantly reduce the waste of system resources and computing power, and improve the overall operating efficiency of the system.

[0067] Eliminate monitoring blind spots

[0068] Through intelligent analysis and event detection, the system can identify key moments (i.e. situations in which users are interested in the camera images) and prioritize the processing of the relevant camera images, reducing monitoring blind spots caused by fixed-cycle polling. For example, intelligent polling can ensure that when important events occur, the camera images are processed and responded to in a timely manner, so that key monitoring information is not missed.

[0069] Improve system efficiency

[0070] The intelligent polling system can effectively improve the processing efficiency of monitoring data and reduce response time by giving priority to high-risk or high-importance camera images (the application scenarios of this system are mainly factory night shifts, inspections, etc. At night, most camera scenes are unmanned, and the main concern is the presence of people. Therefore, the system can quickly conduct a camera inspection to quickly confirm whether there are people entering or leaving the monitoring range. When the system finds that a person appears, it will issue an alarm and continue to monitor the camera where the person appears until the person leaves). This is especially important for monitoring systems with a large number of cameras. Intelligent polling can effectively allocate computing resources to ensure that the system can still maintain good performance under high load conditions.

[0071] In the above embodiments, although the steps are numbered S1, S2, etc., these are only specific embodiments given by the present invention. Those skilled in the art may adjust the execution order of S1, S2, etc. according to actual conditions, which is also within the protection scope of the present invention. It can be understood that in some embodiments, some or all of the above embodiments may be included.

[0072] The present invention also provides a camera monitoring polling switching system, and the specific technical solution is as follows:

[0073] The judgment module is used to: judge in real time whether there is an interesting target in the monitoring area corresponding to the current monitoring camera;

[0074] The switching module is used to: if there is an object of interest, continuously monitor the object of interest through the current monitoring camera;

[0075] If there is no target of interest, after the current monitoring camera monitors for the first preset time period, it switches to the next monitoring camera in a polling order, and uses the next monitoring camera as the current monitoring camera in the judgment module to execute the judgment module.

[0076] Furthermore, if there is an object of interest, the process of continuously monitoring the object of interest through the current monitoring camera is specifically as follows:

[0077] If there is an object of interest, the current surveillance camera continues to track and shoot the object of interest, and after shooting for a second preset time, switches to the next surveillance camera in the polling order, and uses the next surveillance camera as the current surveillance camera in the judgment module to execute the judgment module.

[0078] Furthermore, it also includes: a storage module for storing the identifier corresponding to the current monitoring camera at the end of the polling queue of the polling order when the next monitoring camera executes the judgment module.

[0079] Furthermore, it also includes: a display module for: displaying the polling queue of the polling order.
