Description

Technical Field

[0001] This application relates to the field of video surveillance technology, specifically to a method, device, electronic device, and storage medium for displaying surveillance images. Background Technology

[0002] Surveillance systems are among the most widely used systems in security systems. In the field of fire and smoke monitoring, various locations deploy professional fire and smoke monitoring systems to promptly detect fires and eliminate fire hazards. Typically, a fire and smoke monitoring system includes a server, multiple cameras, and a video player. It is also equipped with smoke detectors, flame sensors, temperature sensors, and other fire and smoke detection sensors. Multiple cameras are used to capture images from different locations within the premises. The smoke and smoke sensors are used to detect smoke, flames, temperature anomalies, and other fire and smoke-related signals in real time at the deployment locations. The video player is used to display the monitoring images captured by each camera in real time. The server is used to control the operation and interaction of the cameras, smoke and smoke sensors, and video player.

[0003] In practical applications of smoke and fire monitoring, there are significant differences in the smoke and fire prevention levels of the monitored areas. For example, the cargo storage areas of warehouse parks and the production workshops of industrial plants are high-smoke and fire prevention level areas, while office areas and passageways are medium- to low-smoke and fire prevention level areas. The corresponding high-prevention-level areas will deploy more types of smoke and fire sensors and are also key areas of focus in the event of a sudden fire. In related technologies, when displaying monitoring images captured by various cameras, video players generally use a flat display method such as a four-grid or nine-grid layout, with each grid displaying one monitoring image. The display area of ​​each image is the same, without prioritization or risk level differentiation.

[0004] When a smoke sensor triggers and sends a smoke detection signal, monitoring personnel cannot quickly locate the corresponding monitoring screen from the tiled image. Furthermore, traditional monitoring screen display methods rely solely on the sensor trigger signal for judgment, failing to combine this with dual verification using smoke image characteristics captured by the camera. This easily leads to invalid monitoring operations due to false sensor triggers. Simultaneously, when multiple smoke sensors trigger simultaneously or sensors in areas with different fire prevention levels trigger sequentially, the tiled display method cannot classify fire risks, making it difficult for monitoring personnel to quickly assess the severity and priority of the fire, potentially delaying early fire response and causing the fire hazard to escalate. Moreover, after highlighting the image corresponding to the triggered sensor, traditional methods lack flexible restoration and tiling rules, failing to simultaneously address both focused fire monitoring in a single area and comprehensive smoke monitoring of the entire area, thus reducing the intelligence and practicality of the smoke monitoring system. Summary of the Invention

[0005] This application provides a monitoring screen display method, electronic device, apparatus, and storage medium, aiming to solve the problems of traditional smoke and fire monitoring screens being displayed flatly, lacking risk classification, and relying solely on sensor signals for judgment, which is prone to misjudgment and untimely fire location.

[0006] In a first aspect, embodiments of this application provide a method for displaying a monitoring screen, including: Acquire the smoke and fire image detection results from the monitoring footage captured by each camera. The smoke and fire image detection results are used to characterize whether smoke and flame features exist in the monitoring footage. The system receives a trigger signal from at least one smoke sensor, which is pre-bonded to the camera. The smoke sensor includes at least one of a smoke sensor, a flame sensor, and a temperature sensor. The smoke-related camera is determined by combining the smoke image detection results and the trigger signal of the smoke sensor, and the smoke risk level corresponding to the smoke-related camera is determined according to the smoke risk judgment rules. The monitoring footage captured by the fireworks-related cameras is obtained based on their identifiers. The monitoring display interface highlights the monitoring images from the fire-related cameras according to the corresponding fire risk level.

[0007] Optionally, in some embodiments of this application, the step of highlighting the monitoring footage of the fireworks-related cameras in the monitoring display interface according to the corresponding fireworks risk level includes: If the smoke and fire risk level corresponding to the smoke and fire associated camera is high risk, the monitoring screen it collects will be displayed in full screen on the monitoring display interface. If the smoke and fire risk level corresponding to the smoke and fire associated camera is medium risk, the monitoring image captured by it will be displayed in the target area of ​​the monitoring display interface. The area of ​​the target area is larger than the display area of ​​the monitoring images captured by the other cameras among the plurality of cameras excluding the smoke and fire associated camera.

[0008] Optionally, in some embodiments of this application, after displaying the monitoring footage captured by the high-risk fireworks-related camera in full screen on the monitoring display interface, the method further includes: When a smoke / fire removal operation is detected, the full-screen display of the monitoring footage captured by the high-risk smoke / fire associated camera ends, and the monitoring footage captured by the multiple cameras is displayed in a tiled manner on the monitoring display interface; or, When the full-screen display of the monitoring images captured by the high-risk fireworks-related cameras reaches the preset warning duration, the full-screen display of the monitoring images captured by the high-risk fireworks-related cameras ends, and the monitoring images captured by the multiple cameras are displayed in a tiled manner on the monitoring display interface.

[0009] Optionally, in some embodiments of this application, displaying the monitoring images captured by the plurality of cameras in a tiled manner on the monitoring display interface includes: Based on the pre-set display areas and scales corresponding to the multiple cameras for smoke and fire prevention, the monitoring images captured by each camera are displayed in a tiled manner on the monitoring display interface; or, Based on the order of smoke and fire prevention levels of the multiple cameras' camera ranges, the display area and size of the monitoring images captured by each of the multiple cameras in the monitoring display interface are determined, and the monitoring images captured by each camera are displayed flatly in the monitoring display interface according to the determined display area and size.

[0010] Optionally, in some embodiments of this application, before highlighting the monitoring footage of the fireworks-related cameras in the monitoring display interface according to the corresponding fireworks risk levels, the method further includes: Determine whether the current monitoring display interface is highlighting the monitoring footage from other fireworks-related cameras in a tiered manner; If the current monitoring display interface is highlighting the monitoring images of other fireworks-related cameras in a tiered manner, then the monitoring display interface will highlight the monitoring images of multiple fireworks-related cameras in a tiered manner from high to low according to the fireworks risk level. Alternatively, the tiered highlighting of the monitoring images of the other fireworks-related cameras will end, and the tiered highlighting of the monitoring images of new fireworks-related cameras will begin according to the corresponding fireworks risk level.

[0011] Optionally, in some embodiments of this application, it further includes: It receives trigger signals from the smoke sensor and smoke image detection data from the monitoring screens captured by each camera. The smoke and fire image detection data are subjected to feature analysis to obtain the smoke and fire image detection results of each camera monitoring screen. The feature analysis includes at least one of smoke feature recognition, flame feature recognition, and temperature anomaly feature recognition. Based on the pre-set binding relationship between the pyrotechnic sensor and the camera, the pyrotechnic image detection results and the trigger signal of the pyrotechnic sensor are combined to determine the pyrotechnic associated camera, and the pyrotechnic risk level corresponding to the pyrotechnic associated camera is determined according to the pyrotechnic risk judgment rules. A tiered display command for fireworks images is generated based on the identifier of the fireworks-related camera and the corresponding fireworks risk level. The tiered display command for fireworks images carries the identifier of the fireworks-related camera and the fireworks risk level information. The command to display the fireworks images in a tiered manner is sent to the video player. The command is used to instruct the video player to highlight the monitoring images of the fireworks-related cameras in the monitoring display interface according to the corresponding fireworks risk level.

[0012] Optionally, in some embodiments of this application, before determining the smoke-associated camera based on the pre-set binding relationship between the smoke sensor and the camera, combined with the smoke image detection result and the trigger signal of the smoke sensor, and determining the smoke risk level corresponding to the smoke-associated camera according to the smoke risk assessment rules, the method further includes: The relationship between the deployment location of each pyrotechnic sensor, the sensor type, the camera's field of view, and the pyrotechnic monitoring coverage area is determined based on the relationship between each pyrotechnic sensor and the camera's field of view. Based on the smoke and fire prevention level of the camera's field of view, the triggering type of the smoke and fire sensor, and the feature matching degree of the smoke and fire image detection, set smoke and fire risk judgment rules and corresponding image highlighting rules for different smoke and fire triggering scenarios; Based on the smoke and fire sensor attached to each camera and the smoke and fire risk assessment rules, a correlation relationship is established between the smoke and fire sensor, the camera, and the smoke and fire risk level.

[0013] Secondly, embodiments of this application provide a monitoring screen display device, including: The first acquisition module is used to acquire the smoke and fire image detection results of the monitoring images captured by each camera.

The display module is used to highlight the monitoring images of the fireworks-related cameras in the monitoring display interface according to the corresponding fireworks risk level.

[0014] Accordingly, this application also provides an electronic device, including a memory, a processor, and a processor program stored in the memory and executable on the processor, wherein the processor executes the program as described in any of the preceding methods.

[0015] This application also provides a storage medium storing a processor program that, when executed by a processor, implements the method described in any of the preceding claims.

[0016] This application provides a method, apparatus, electronic device, and storage medium for displaying surveillance footage. The method involves acquiring smoke and fire image detection results from surveillance footage captured by various cameras. These results characterize the presence of smoke and flame features in the surveillance footage. The method also includes receiving trigger signals from at least one smoke sensor, which is pre-bonded to a camera. The smoke sensor includes at least one of a smoke sensor, a flame sensor, and a temperature sensor. The method combines the smoke and fire image detection results and the trigger signals from the smoke sensors to identify smoke-associated cameras. Based on smoke and fire risk assessment rules, the method determines the smoke and fire risk level corresponding to each associated camera. Finally, the method retrieves the images captured by the associated cameras based on their identifiers. The monitoring screens are displayed in the monitoring display interface, highlighting the monitoring screens of the smoke and fire associated cameras according to the corresponding smoke and fire risk levels. The monitoring screen display scheme provided in this application features flexible screen display switching rules, supporting both manual smoke and fire deactivation and automatic preset warning duration full-screen recovery. Simultaneously, the tiled display can be configured in terms of area and size based on the smoke and fire prevention level, balancing focused monitoring of single-area fires and comprehensive smoke and fire monitoring of the entire area. Furthermore, for scenarios where multiple smoke and fire sensors trigger simultaneously, a multi-level highlighting method based on smoke and fire risk levels from high to low is designed, and it also supports replacing old fire screens with new ones, adapting to complex sudden smoke and fire scenarios and improving the practicality of the scheme.

[0021] The monitoring screen display method of this disclosure is applicable to fire and smoke security monitoring scenarios. It can be deployed and implemented in various monitored areas such as buildings, warehouse parks, industrial plants, and commercial complexes that require fire and smoke monitoring and fire early warning. The core of the method is to achieve the linkage and cooperation between fire and smoke sensors and cameras, perform dual verification of fire conditions by combining fire and smoke image detection results, and highlight the fire and smoke risk level classification in the monitoring screen. The specific implementation method of this disclosure will be described in detail below with reference to the accompanying drawings.

[0022] Figure 1 is a schematic diagram of the implementation environment of a monitoring screen display method according to an exemplary embodiment. As shown in Figure 1, the implementation environment includes a video player 101, a server 102, multiple smoke and fire sensors 103 and multiple cameras 104. The devices are connected to each other through wired or wireless communication, supporting bidirectional transmission of data and instructions. The communication protocol can adopt conventional security monitoring system communication protocols such as TCP / IP and UDP, or it can be customized according to the actual application scenario.

[0023] Camera 104: Used to collect real-time monitoring images from different locations within the monitored area. It supports high-definition video capture and image data transmission. The deployment location of the camera is set according to the smoke and fire prevention level of the monitored area. High-definition zoom cameras are deployed in areas with high smoke and fire prevention levels to ensure image clarity and detail capture capabilities. The monitoring images captured by the camera are sent to server 102 in the form of video streams and image frames, or directly to video player 101. At the same time, the camera can have a built-in image detection chip to perform preliminary smoke and fire image feature detection on the captured images, or send the raw image data to server 102 for centralized detection and analysis.

[0024] Smoke and fire sensor 103 includes at least one of a smoke sensor, a flame sensor, and a temperature sensor. The smoke sensor is used to detect the smoke concentration in the environment, the flame sensor is used to detect the flame light signal (such as infrared or ultraviolet light) in the environment, and the temperature sensor is used to detect the real-time temperature and the rate of abnormal temperature change in the environment. All types of smoke and fire sensors are deployed at key locations for smoke and fire prevention in the monitored area, corresponding to the camera range of the camera 104. When the parameters detected by the smoke and fire sensor exceed the preset threshold, the sensor is triggered and sends a trigger signal to the server 102. The trigger signal contains information such as the sensor's identification, sensor type, deployment location, and trigger parameter value.

[0025] Server 102: As the core control device of the entire fire monitoring system, it is used to control the working status of camera 104 and fire sensor 103, receive and process the trigger signal of fire sensor 103 and the fire image detection data of camera 104, establish the binding relationship between fire sensor and camera, set fire risk judgment rules, determine the fire-related camera and the corresponding fire risk level, and generate the corresponding fire image graded display command to send to video player 101; at the same time, server 102 can store the monitoring images collected by camera and the detection data of fire sensor, which is convenient for subsequent fire source tracing and data analysis.

[0026] Video player 101: Used to receive and play the monitoring images captured by each camera 104 in real time, receive the smoke and fire image classification display command sent by server 102, obtain the monitoring images of the smoke and fire related cameras according to the command, and highlight them in the monitoring display interface according to the smoke and fire risk level; at the same time, video player 101 supports manual operation interaction, and can receive the smoke and fire cancellation operation, screen switching operation, etc. from the monitoring personnel, so as to realize flexible switching of monitoring images and restoration of display mode.

[0027] In this embodiment of the invention, some or all of the multiple cameras 104 are uniquely bound to the smoke sensor 103. When any smoke sensor 103 is triggered, the server 102 performs dual verification by combining the smoke image detection results from the camera screen to determine the smoke-associated camera and classify the risk level. The video player 101 highlights the monitoring screen of the smoke-associated camera according to the server's instructions, thereby achieving accurate fire location and visual classification.

[0028] Referring to the implementation environment diagram shown in Figure 1, this method is applied to the video player 101. As shown in Figure 2, the monitoring screen display method includes the following steps: Step 201: Obtain the smoke and fire image detection results from the monitoring footage captured by each camera. The smoke and fire image detection results are used to characterize whether there are smoke and fire features in the monitoring screen. They can also include information such as the feature matching degree of smoke / fire, feature location, and area ratio. They are an important basis for judging whether there is a real fire in the monitored area.

[0029] The video player 101 acquires the fireworks image detection results in two ways: one is to receive them directly from the server 102, which performs feature analysis on the fireworks image detection data collected by the camera and then sends the unified fireworks image detection results to the video player 101; the other is to receive them directly from the camera 104. If the camera has a built-in image detection chip, it can perform fireworks image feature detection on its own and send the detection results to the video player 101.

[0030] The fireworks image detection results are transmitted in the form of data frames. Each frame corresponds to the identifier of a camera. The video player 101 associates and stores the camera identifiers with the detection results for easy subsequent querying and matching.

[0031] Step 202: Receive trigger signals from at least one smoke sensor. The smoke sensor and the camera are pre-bound. The smoke sensor includes at least one of smoke sensor, flame sensor and temperature sensor. The trigger signal contains key information such as sensor identification, sensor type, deployment location and trigger parameter value. The video player 101 can receive the smoke sensor trigger signal forwarded by the server 102 through wired or wireless communication, or it can directly receive the trigger signal sent by the smoke sensor.

[0032] In practical applications, there may be situations where a single pyrotechnic sensor triggers or multiple pyrotechnic sensors trigger simultaneously. When multiple sensors trigger, the video player 101 receives and buffers multiple trigger signals, sorts them according to the order of reception time or the sensor deployment location, so as to facilitate a comprehensive judgment based on the pyrotechnic image detection results.

[0033] Step 203: Combine the smoke image detection results and the trigger signal of the smoke sensor to determine the smoke-related camera, and determine the corresponding smoke risk level according to the smoke risk assessment rules. A smoke-fire associated camera refers to a camera that is bound to a triggered smoke sensor and whose captured monitoring footage contains smoke and fire image features (or whose feature matching degree reaches a preset threshold). It is the monitoring camera corresponding to the location of the fire. Video player 101 first queries the pre-stored smoke sensor-camera binding relationship based on the sensor identifier in the trigger signal, filtering out candidate cameras bound to the trigger sensor. Then, it matches the identifier of the candidate camera with the smoke and fire image detection results to determine whether smoke, flames, or other smoke and fire features exist in the candidate camera's monitoring footage. If so, the candidate camera is identified as a smoke-fire associated camera.

[0034] If no smoke or fire image features are detected in the monitoring footage of a candidate camera, it is determined that the smoke or fire sensor has been falsely triggered. The camera will not be identified as a smoke or fire associated camera, and no further highlighting operation will be performed, effectively avoiding invalid monitoring.

[0035] The fire risk level is a classification of the severity of a fire based on fire risk assessment rules. In this embodiment, it is mainly divided into two levels: high risk and medium risk. The fire risk assessment rules are pre-set by server 102 and sent to video player 101 for storage. The core of the assessment combines three dimensions: the fire prevention and control level within the camera's field of view, the trigger type of the fire sensor, and the feature matching degree of the fire image detection. A specific example of the assessment logic is as follows: If the camera's field of view is a high-smoke-control area (such as a cargo storage area in a warehouse park), and the triggered sensor is a flame sensor / temperature sensor (strong smoke signal), or the feature matching degree of the smoke image detection is ≥80%, then the smoke risk level corresponding to the smoke-related camera is determined to be high risk. If the camera's field of view is within a medium / low level of smoke and fire prevention (such as an office area), and the triggered sensor is a smoke sensor (weak smoke and fire signal), and the feature matching degree of the smoke and fire image detection is 50%-80%, then the smoke and fire risk level corresponding to the camera is determined to be medium risk.

[0036] The fire risk assessment rules can be customized according to the actual situation of the monitored area. The video player 101 can receive the rule update instructions sent by the server 102 and update the local fire risk assessment rules in real time.

[0037] Step 204: Obtain the monitoring footage captured by the cameras associated with the fireworks based on their identifiers. After identifying the camera associated with the fireworks, video player 101 retrieves the corresponding real-time monitoring footage based on its unique identifier. There are two ways to retrieve the footage: First, it sends a footage retrieval request to server 102. Server 102 then selects the footage from the multiple camera monitoring feeds it receives and sends it to video player 101 as a high-definition video stream. Second, it directly sends a footage retrieval command to the camera associated with the fireworks. Upon receiving the command, the camera directly sends the real-time high-definition monitoring footage to video player 101.

[0038] To ensure real-time fire monitoring, the monitoring images from the smoke and fire related cameras are transmitted in high-definition video stream with a frame rate of no less than 25fps, ensuring that monitoring personnel can clearly see the development and changes of the fire.

[0039] Step 205: In the monitoring display interface, the monitoring images of the smoke-related cameras are highlighted according to the corresponding smoke risk level. Video Player 101 uses different display methods to highlight information based on the smoke and fire risk level corresponding to the cameras associated with the smoke and fire. The core methods are high-risk full-screen display and medium-risk target area display. The highlighted monitoring footage is a real-time high-definition video stream, ensuring clear display of fire details. The specific implementation method is as follows: High-risk full-screen display: If the smoke and fire risk level corresponding to the camera associated with the smoke and fire is high-risk, the monitoring screen will display the monitoring footage it has collected in full screen on the monitoring display interface. At this time, the monitoring display interface will only display the high-risk footage and will not display the footage from other cameras, allowing monitoring personnel to focus on observing the details of the fire and quickly grasp the development of the fire. Medium-risk target area display: If the smoke and fire risk level corresponding to the smoke and fire related camera is medium risk, the monitoring screen captured by it will be displayed in the target area of ​​the monitoring display interface. The area of ​​the target area is larger than the display area of ​​other camera screens. The target area can be set in the center of the monitoring display interface (the visual focus position), and the area can be 2 times or more than that of other screens, so as to ensure the prominent display of the fire screen while also taking into account the monitoring screens of other areas.

[0040] Before executing this step, the video player 101 needs to determine whether the current monitoring display interface is currently highlighting the monitoring images of other fire-related cameras in a tiered manner. If there are no other highlighted images on the current interface, the tiered highlighting can be performed directly according to the above rules. If the current interface is highlighting the images of other fire-related cameras, there are two processing methods: First, display them sequentially according to risk level. On the monitoring display interface, the images of multiple fire-related cameras are highlighted in a tiered manner according to the fire risk level from high to low. For example, high-risk images are displayed in full screen, and medium-risk images are displayed in a large area on the side, so as to achieve simultaneous monitoring of multiple fires. Second, replace the old images with new ones. The highlighting of the original fire-related camera images ends, and the highlighting of the new fire-related camera images begins according to the corresponding risk level. This is suitable for scenarios where fire response has a clear priority.

[0041] Furthermore, when the footage from cameras associated with high-risk fireworks is displayed in full screen, to ensure comprehensive monitoring of fireworks across the entire area, the video player 101 supports two full-screen display restoration methods, which can be set according to the actual application scenario: Manual recovery: When the smoke removal operation by the monitoring personnel is detected, the full-screen display ends and the tiled display of the multi-camera images is restored. The smoke removal operation includes clicking, double-clicking, and swiping on the full-screen screen, or clicking the preset recovery button or shortcut key on the monitoring display interface. The operation method is simple and easy to understand and adapts to the operating habits of the monitoring personnel. Automatic recovery: When the full-screen display duration reaches the preset warning duration, the full-screen display will automatically end and the multi-camera image will be restored to a tiled display. The preset warning duration can be set according to the actual situation of the monitored area, such as 30 seconds, 60 seconds, 120 seconds, etc., to ensure that the monitoring personnel have enough time to observe the fire and make initial handling, while avoiding the omission of fires in other areas due to the single full-screen display.

[0042] When video player 101 ends full-screen display and resumes tiled display, it adopts a tiled display method that matches the smoke and fire prevention level, specifically including two types: Preset Fire Prevention Area Tiling: Based on the pre-set display areas and ratios for fire prevention of multiple cameras, the images of each camera are tiled in the monitoring display interface; Server 102 will set a fixed display area and ratio for each camera according to the fire prevention layout of the monitored area. The display ratio of camera images in areas with high fire prevention levels can be appropriately increased. Video player 101 will tile the images according to the preset rules to ensure that the images of key prevention areas receive special attention; Fire prevention and control level sorting and tiling: Based on the order of fire prevention and control level of multiple camera ranges, the display area and display size of each camera's image are determined and displayed in a tiled manner on the monitoring display interface; the images of cameras in high fire prevention and control level areas are placed in the center of the monitoring display interface in a large area, while the images of medium and low prevention and control level areas are placed on the side in a small area, so as to match the prevention and control level with the display priority, allowing monitoring personnel to quickly focus on the images of key areas.

[0043] Referring to the implementation environment diagram shown in Figure 1, the monitoring screen display method includes the following steps: It receives trigger signals from the smoke sensor and smoke image detection data from the monitoring screens captured by each camera. Server 102, as the core control device of the fireworks monitoring system, establishes connections with all fireworks sensors and cameras via wired or wireless communication, and receives various data and signals in real time. When the parameters detected by the smoke sensor exceed the preset threshold, the sensor is triggered and sends a trigger signal to the server 102. The trigger signal contains information such as sensor identification, type, deployment location, and trigger parameter values. The server 102 receives and caches the trigger signal in real time to prepare for subsequent camera matching. Each camera sends the captured monitoring images to server 102 in the form of image frames and video streams. This data is fireworks image detection data, which includes information such as camera identification, acquisition time, and image pixel data. Server 102 receives and stores this data and simultaneously initiates the fireworks image feature analysis process.

[0044] Server 102 supports simultaneous data reception from multiple devices and can classify and store the received data and signals according to device identification to ensure data orderliness and traceability.

[0045] Feature analysis was performed on the smoke and fire image detection data to obtain the smoke and fire image detection results from the monitoring screens of each camera. Feature analysis is the core step in smoke and fire image detection. Server 102 processes the smoke and fire image detection data using image recognition algorithms to extract smoke and fire-related features from the image and determine whether a fire exists. Feature analysis includes at least one of smoke feature recognition, flame feature recognition, and temperature anomaly feature recognition. The specific analysis methods are as follows: Smoke feature recognition: By analyzing features such as image grayscale values, texture, and contours, the system identifies whether there are smoke areas in the image. It also calculates the matching degree between smoke features and a preset smoke template to determine information such as the location and area ratio of the smoke. Flame feature recognition: By using color features (such as the pixel ratio of red, orange and yellow) and dynamic features (such as the flickering and spreading of flames), the system identifies whether there are flame areas in the image, calculates the flame feature matching degree, and determines the core location and spread trend of the flame. Temperature anomaly feature identification: If the camera is a thermal imaging camera, the server 102 analyzes the thermal imaging image data, identifies temperature anomaly areas in the image, and determines whether there is a high-temperature fire by combining the temperature threshold, and determines the location, temperature value and other information of the temperature anomaly area.

[0046] The image recognition algorithm used by server 102 can be a deep learning algorithm (such as YOLO, CNN), a traditional machine vision algorithm, etc. The accuracy of the algorithm can be adjusted according to the actual needs of smoke and fire monitoring. After the feature analysis is completed, server 102 generates smoke and fire image detection results corresponding to each camera. The detection results include information such as camera identification, presence of smoke and fire features, feature type, feature matching degree, and feature location, and the detection results are stored and forwarded.

[0047] Based on the pre-set binding relationship between the smoke sensor and the camera, the smoke image detection results and sensor trigger signals are combined to determine the smoke-associated camera, and the corresponding smoke risk level is determined according to the smoke risk assessment rules. Before performing this step, server 102 needs to complete the binding relationship between the smoke sensor and the camera and the setting of smoke risk assessment rules in advance. This is the basis for subsequent judgment. The specific establishment and setting methods are as follows: Establishing the smoke sensor-camera binding relationship: The server determines the smoke sensor bound to each camera based on the deployment location and sensor type of each smoke sensor, its relationship with the camera's field of view and the smoke monitoring coverage area. The core principle of binding is that the sensor deployment location is within the camera's field of view, and the camera's monitoring angle can clearly capture the image of the sensor deployment location. Simultaneously, it can match the corresponding camera type based on the sensor type, such as matching a flame sensor with a high-definition zoom camera, and a smoke sensor with a wide-angle camera. After the binding relationship is established, the server generates a smoke sensor-camera binding relationship table, which contains information such as sensor identifier, sensor type, deployment location, bound camera identifier, and camera's field of view. Setting Fire Risk Assessment Rules: The server sets fire risk assessment rules and corresponding image highlighting rules for different fire triggering scenarios based on the fire prevention and control level of the camera's field of view, the triggering type of the fire sensor, and the feature matching degree of the fire image detection. The fire prevention and control level is set by the management of the monitored area according to the actual situation (high / medium / low). The sensor triggering type is divided into strong trigger (flame, temperature sensor) and weak trigger (smoke sensor). Different thresholds are set for the feature matching degree (such as 50% and 80%). The server combines the parameters of the three dimensions to formulate a clear risk level assessment logic and set the corresponding highlighting method (full screen / target area). Establish the association between smoke and fire sensors, cameras, and smoke and fire risk levels: Based on the smoke and fire sensor bound to each camera and the aforementioned smoke and fire risk determination rules, the server associates and stores the sensor identifier, camera identifier, smoke and fire risk level, and highlighting method to form an association database, providing data support for subsequent rapid determination.

[0048] After completing the above basic work, server 102 begins to determine the smoke-related cameras and the smoke risk level: First, based on the sensor identifier in the trigger signal, the binding relationship table is queried to filter out candidate cameras; then, the candidate camera identifier is matched with the smoke image detection results to determine whether there are smoke features and to determine the smoke-related cameras; finally, based on the smoke risk judgment rules, combined with the prevention and control level, sensor trigger type, and feature matching degree, the smoke risk level (high / medium) corresponding to the smoke-related cameras is determined.

[0049] A tiered display command for fireworks images is generated based on the identifiers of the cameras associated with the fireworks and the corresponding fireworks risk levels. The fireworks display tiered display command is a control instruction sent by the server to the video player, which instructs the video player to highlight the images from designated cameras in a tiered manner. This command is structured data and contains key information such as command identifier, fireworks-related camera identifier, fireworks risk level, highlighting method, and instruction effective time. The highlighting method corresponds one-to-one with the fireworks risk level (high risk - full-screen display, medium risk - target area display).

[0050] Based on the identified camera identifiers associated with the fireworks and the level of fireworks risk, the server generates a tiered display command for the fireworks images according to a preset instruction format. The command is transmitted in an encrypted format to ensure that it is not tampered with during transmission, thereby improving system security.

[0051] If there are multiple cameras associated with the fireworks, the server can generate a comprehensive command that includes information from multiple cameras and their risk levels, or it can generate multiple individual commands according to the risk level from high to low. The video player will receive the commands and display them accordingly.

[0052] Send the command to the video player to display the fireworks scene in different levels. After the server generates a command to display the fireworks scene in a tiered manner, it sends the command to the video player via wired or wireless communication. The communication method is consistent with the overall communication protocol of the system to ensure fast and stable transmission of the command. To ensure the real-time nature of fire monitoring, the transmission delay of the command is controlled within 1 second, allowing the video player to respond quickly and highlight the scene in a tiered manner.

[0053] If the video player fails to receive the instruction, the server will resend the instruction. The number of resends can be preset (e.g., 3 times). If the resend still fails after multiple attempts, the server will issue a communication failure alarm to remind monitoring personnel to check the device's communication status.

[0054] After receiving the command to display the fireworks scene in a graded manner, the video player parses and verifies the command, extracts the camera identifier and the fireworks risk level, and then performs subsequent image acquisition and graded highlighting operations, thereby enabling the server to remotely control the video player's display mode.

[0055] This application provides a method for displaying surveillance footage, which involves acquiring smoke and fire image detection results from surveillance footage captured by various cameras. These smoke and fire image detection results characterize the presence of smoke and flame features in the surveillance footage. The method also includes receiving trigger signals from at least one smoke and fire sensor, which is pre-bonded to a camera and includes at least one of a smoke sensor, a flame sensor, and a temperature sensor. The method further involves combining the smoke and fire image detection results and the trigger signals from the smoke and fire sensors to determine smoke-associated cameras, and determining the corresponding smoke and fire risk level of each associated camera according to smoke and fire risk assessment rules. Finally, the method retrieves the surveillance footage captured by each associated camera based on its identifier. The monitoring display interface highlights the monitoring images of the smoke-related cameras according to the corresponding smoke risk level. The monitoring display scheme provided in this application features flexible display switching rules, supporting both manual smoke cancellation and automatic preset warning duration full-screen recovery. The tiled display can be configured in terms of area and size based on the smoke control level, balancing focused monitoring of single-area fires and comprehensive smoke monitoring of the entire area. Furthermore, for scenarios where multiple smoke sensors trigger simultaneously, a multi-level highlighting method based on smoke risk level from high to low is designed. It also supports replacing old fire images with new ones, adapting to complex sudden smoke incidents and improving the practicality of the scheme.
