Description

Technical Field

[0001] This application relates to the field of image devices, and in particular to a method, system, device, and medium for determining regional intrusion in complex outdoor scenes. Background Technology

[0002] Reserve land refers to land that the government has legally acquired in accordance with the regulations governing the management of national reserve land. Reserve land management refers to the entrusted management and oversight by a company to prevent infringement upon the rights of the reserve land.

[0003] The entrusted company is required to conduct on-site inventory and verification of the location, management boundary, land area, number and area of ​​above-ground buildings and structures, current status of other attachments, and topography of the reserve land under its management, and compile the on-site inventory and verification results into a management responsibility list. This is to prevent any infringement on the rights of the reserve land. The entrusted company can also take effective measures to manage the reserve land, promptly detect and stop any illegal encroachment or damage to the current state of the reserve land, prevent any new unauthorized construction, dumping of soil, illegal logging, or discharge of pollutants within the reserve land, and prevent the reclamation of land within the construction area. The entrusted company is also responsible for the daily cleaning of the reserve land and simple landscaping work.

[0004] Due to the uncertainty of the location of the reserve land, some of the surrounding land has been put into normal development and use, which means that people, animals, vehicles and other strange animals may enter the reserve land from time to time. Therefore, it is urgent to make appropriate adjustments to the accuracy and methods of supervision of reserve land in complex outdoor scenarios. Summary of the Invention

[0005] To improve the accuracy of monitoring land reserves in complex outdoor scenarios, this application provides a method, system, device, and medium for determining regional intrusion in complex outdoor scenarios.

[0006] Firstly, this application provides a method for determining regional intrusion in complex outdoor scenarios, which employs the following technical solution:

[0007] A method for determining area intrusion in complex outdoor scenarios includes the following steps:

[0008] Receive abnormal monitoring information sent back by outdoor terminals;

[0009] Based on the aforementioned abnormal monitoring information, the corresponding primary regulatory area for reserve land is obtained;

[0010] Analyze abnormal intrusion behaviors within the primary supervision area of ​​the reserve land and determine whether the abnormal intrusion behaviors pose a dangerous event to the current reserve land.

[0011] If so, the early warning and response plan will be activated;

[0012] If not, a second assessment will be made of the current abnormal intrusion behavior, and an overlapping regulatory area will be constructed based on the current reserve land area. The temporary intrusion monitoring plan will be implemented to assess the abnormal intrusion behavior in the overlapping regulatory area.

[0013] By adopting the above technical solution: if there are many people around the reserve land, it is necessary to judge the abnormal invasive behavior of invasive animals in the reserve land.

[0014] If a dangerous incident occurs, such as long-term occupation or damage to the reserve land, it can be determined that the current invasion of foreign animals poses a dangerous incident to the reserve land. In this case, the regulatory personnel need to activate the early warning and handling plan to deal with the dangerous incident accordingly.

[0015] If no dangerous incident occurs, such as when nearby residents or small animals enter the reserve land to pass by or rest temporarily, a secondary assessment of the animal's behavior (abnormal intrusion behavior) is required. An overlapping monitoring zone should be established for the animal's intrusion range. If the animal does not cause further dangerous incidents to the reserve land within the overlapping monitoring zone, some animals may be allowed to enter the reserve land temporarily. This reduces the possibility of false alarms from the system regarding animal intrusions, thereby improving the monitoring accuracy of various types of reserve land in complex outdoor scenarios and humanizing the monitoring methods so as not to affect the normal life patterns of local residents and animals.

[0016] Optionally, the step of analyzing abnormal intrusion behavior within the primary supervision area of ​​the reserve land and determining whether the abnormal intrusion behavior poses a dangerous event to the current reserve land specifically includes the following sub-steps:

[0017] Based on abnormal monitoring information, unusual animals are obtained and identified, and the identification results are exported. The identification results include residents, animals, and vehicles.

[0018] If the identification result is a resident or an animal, then identify the invasion path of the alien animal into the primary regulatory area of ​​the reserve land and calculate the invasion duration;

[0019] When the length of the intrusion path or the duration of the intrusion exceeds the threshold, it is determined that the abnormal intrusion behavior has caused a dangerous event to the current reserve land; if the identification result is a vehicle, the intrusion behavior of a foreign animal intruding into the first-level supervision area of ​​the reserve land is identified, and the intrusion behavior includes driving through, parking, and separation of people and vehicles;

[0020] When an intrusion is detected as parking or separation of pedestrians and vehicles, it is determined that the abnormal intrusion poses a dangerous event to the current land reserve.

[0021] By adopting the above technical solution, the types of animals entering the reserve land supervision area can be initially identified, and then the actions can be identified according to different animal types, thereby improving the accuracy of action analysis.

[0022] Optionally, the step of making a secondary judgment on the current abnormal intrusion behavior and constructing an overlapping regulatory area based on the current reserve land area specifically includes the following sub-steps:

[0023] The movement trajectory coordinates of alien animals are recorded based on the path tracking algorithm, and the invasion path is stored in the form of a sequence of movement trajectory coordinate points; the invasion action of alien animals is analyzed to predict the invasion path of alien animals.

[0024] Construct overlapping surveillance areas based on the predicted intrusion paths;

[0025] If the actual intrusion path deviates from the predicted intrusion path by more than a threshold and exceeds the current overlapping regulatory area, it is determined that the intruding alien animal has caused a dangerous event.

[0026] By adopting the above technical solution, we can use big data on the invasion behavior of alien animals and deep neural network models to analyze each invasion action of the alien animal in real time and predict the multiple branches of the invasion path that the alien animal may take in the future.

[0027] Furthermore, relying on the predicted intrusion path, an overlapping monitoring area can be constructed using a spatial geometric dynamic programming algorithm. This area is not a fixed, rigid pattern, but rather its boundaries and range are dynamically adjusted according to the real-time predicted path. Once the actual intrusion path is detected to deviate from the predicted intrusion path by more than a threshold and exceeds the currently dynamically adapted overlapping monitoring area, the multi-source risk assessment model is immediately used to determine that the intruding alien animal is highly likely to cause a dangerous event.

[0028] Optionally, the step of constructing the overlapping surveillance area based on the predicted intrusion path further includes the following sub-steps:

[0029] The land reserves are spatially gridded, with each grid assigned spatial coordinates, terrain attributes, and scene features.

[0030] Guided by the predicted invasion path, with the starting point as the core diffusion source, the system calculates and outlines the most suitable regulatory range in real time based on the movement speed and turning probability of the alien animal, as well as the accessibility and concealment of the surrounding environment.

[0031] By adopting the above technical solutions, if the predicted intrusion path is close to densely populated residential areas, considering the risk to human safety, the grid weight is tilted towards expanding the protection range, and priority is given to ensuring that the areas where residents are active are included in key supervision; if it is near complex wild green areas, the selection and connection of grids are dynamically adjusted in combination with the obstruction or cover effect of vegetation height and density on animal movement, so as to accurately define the supervision boundary and realize the transformation from fixed area division to dynamic and intelligent definition.

[0032] Optionally, the step of determining the implementation of a temporary intrusion monitoring plan for abnormal intrusion behavior in overlapping monitoring areas specifically includes the following sub-steps:

[0033] When a foreign animal is detected in the overlapping regulatory area and leaves the overlapping regulatory area, it is detected whether there are any residual foreign objects in the current primary regulatory area and the overlapping regulatory area.

[0034] If present, the foreign animal is marked to prevent it from re-entering the primary or overlapping regulatory areas, and a report on the remaining foreign object to be cleaned is sent.

[0035] By adopting the above technical solution, foreign objects remaining in the reserve land can be cleaned up as soon as possible. At the same time, the foreign animals that caused the foreign objects can be marked to reduce the possibility of the foreign animals re-entering the reserve land and causing secondary foreign objects.

[0036] Optionally, the information to be reported regarding the residual foreign object includes the location coordinates of the residual foreign object, the estimated difficulty of cleaning, and the recommended cleaning time limit.

[0037] Optionally, determine whether the abnormal intrusion behavior poses a dangerous event to the current land reserve, and construct a risk assessment model; refine the risk assessment based on the following formula:

[0038] Risk value = ∑(hazard coefficient of each intrusion factor × corresponding weight);

[0039] Risk level of intrusion behavior type: Construction damage is marked as A, garbage dumping is marked as B, and arson is marked as C. The risk level can be flexibly set in the system according to the actual degree of harm.

[0040] Intrusion Duration Risk Factor: The risk factor increases by 1 for every 30 seconds exceeding the intrusion duration. Let the duration be t seconds, and the risk factor be...

[0041] The risk factor between the intrusion location and the critical facility is calculated using a Gaussian function. The distance is given as d meters, and the radius of influence of the critical facility is r = 10 meters. Weighting: The weight of the intrusion behavior type is set to M, the weight of the intrusion duration is set to N, and the weight of the distance between the intrusion location and the critical facility is set to X, M+N+X=1.

[0042] By adopting the above technical solution, adjustments can be made according to the actual situation. A risk threshold is used for judgment; if the risk value is greater than or equal to the threshold, it is determined to be a dangerous event.

[0043] Secondly, the outdoor complex scene area intrusion detection system provided in this application adopts the following technical solution: The outdoor complex scene area intrusion detection system includes:

[0044] The control unit is used to execute the area intrusion detection method in complex outdoor scenarios.

[0045] Multiple offline terminals are used to collect real-time image information from various reserve land areas;

[0046] Multiple feedback terminals are used by supervisory personnel in each reserve land area to receive real-time feedback information;

[0047] The data processing module is used to process the real-time image information transmitted from various offline terminals and feed the processing results back to the control terminal.

[0048] Thirdly, the computer device provided in this application adopts the following technical solution:

[0049] A computer device includes a processor, a memory, and a computer program stored in the memory and executable on the processor. When the processor executes the computer program, it implements the aforementioned method for determining regional intrusion in complex outdoor scenarios.

[0050] By adopting the above technical solution, a computer device is provided that can execute the above-mentioned method for determining regional intrusion in complex outdoor scenarios.

[0051] Fourthly, the computer-readable storage medium provided in this application adopts the following technical solution:

[0052] A computer-readable storage medium storing a computer program; when executed by a processor, the computer program implements the above-described method for determining regional intrusion in complex outdoor scenarios.

[0053] By adopting the above technical solution, a computer program carrier for a method of determining regional intrusion in complex outdoor scenarios is provided.

[0054] In summary, this application includes at least the following beneficial technical effects:

[0055] 1. If a dangerous incident occurs, such as long-term occupation or damage to the reserve land, it can be determined that the current invasion of foreign animals poses a dangerous incident to the reserve land. In this case, the supervisory personnel need to activate the early warning and handling plan to deal with the dangerous incident accordingly.

[0056] 2. If no dangerous incident occurs, for example, if it is only a nearby resident / small animal passing through / resting temporarily on the reserve land, then the behavior of the alien animal entering the reserve land (abnormal intrusion behavior) needs to be reassessed, and an overlapping monitoring zone should be constructed for the intrusion range of the alien animal. If the alien animal does not cause further dangerous incidents to the reserve land within the overlapping monitoring zone, then some alien animals are allowed to enter the reserve land temporarily, reducing the possibility of false alarms for alien animal intrusion by the system. This improves the monitoring accuracy of various types of reserve land in complex outdoor scenarios and allows for a more humane adjustment of the monitoring method, so as not to affect the normal life of local residents and animals.

[0062] To make the purpose, technical solution, and advantages of this application clearer, the following description is provided in conjunction with the appendix. Figures 1-3 The present application will be further described in detail below with reference to embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the application.

[0063] This application discloses a method for determining regional intrusion in complex outdoor scenarios.

[0064] refer to Figure 1 and Figure 2 The method for determining area intrusion in complex outdoor scenarios includes the following steps:

[0065] S100: Receives abnormal monitoring information sent back by outdoor terminals.

[0066] Specifically, in this embodiment, the offline terminal 2 includes monitoring information collection equipment and site equipment. After the reserve land is taken over for supervision, the supervisor will install monitoring information collection equipment such as pan-tilt-zoom (PTZ) cameras, thermal imaging equipment, and high-definition cameras on-site to monitor the reserve land in real time, according to the actual situation of the reserve land. If the reserve land area is too large, a separate personnel supervision booth needs to be set up on the reserve land site. The site equipment in the supervision booth (e.g., edge computing gateways, industrial routers, etc., which are intelligent devices that can analyze and process the collected monitoring data in real time near the data source) can initially collect the monitoring information collected by various outdoor terminals in the current reserve land so that the personnel in the supervision booth can remotely view it. Then the site equipment sends the monitoring information to the control terminal 1 so that the supervisor can centrally supervise all the reserve land in the jurisdiction.

[0067] The received monitoring information is then imported into the data processing module 4 by the control terminal 1. The data processing module 4 monitors whether there are any abnormalities in each monitoring information. If there are any abnormalities, the data processing module 4 sends the abnormal monitoring information back to the control terminal 1.

[0068] Alternatively, the data processing module 4 can be connected to the equipment at each site, allowing each monitoring booth to directly and intelligently monitor the local reserve land. If any anomalies are found, the data processing module 4 will send the anomaly information to the corresponding feedback terminal 3, so that the monitoring personnel in the monitoring booth can handle the anomalies in a timely manner through the feedback terminal 3.

[0069] S200: Obtain the corresponding primary regulatory area for reserve land based on abnormal monitoring information.

[0070] Reference Figure 2 and Figure 3 Specifically, when the control terminal 1 receives abnormal monitoring information, it obtains the first-level supervision area within the corresponding reserve land according to the reserve land number of the abnormal monitoring information, and determines whether the intrusion behavior that triggered the current abnormality occurred within the first-level supervision area. If so, step S300 is executed. If not, the abnormal behavior is judged to determine whether the abnormal behavior violates the relevant public security regulations and other laws. If so, the supervisory personnel execute the corresponding public security plan.

[0071] For example, if the current reserve land is located in an area with high population density, and a drunk person passes by and enters the monitoring range, and then falls asleep or lies down while intoxicated, an anomaly will be triggered in data processing module 4. However, if the person's intoxication or other behavior does not occur within the reserve land (the first-level monitoring area) but only on the edge of the reserve land, it is not within the scope of responsibility of the reserve land supervisor. The supervisor only needs to call the police or make a remote announcement or other security plan to handle such situations.

[0072] S300: Analyze abnormal intrusion behavior within the primary supervision area of ​​reserve land and determine whether the abnormal intrusion behavior poses a dangerous event to the current reserve land;

[0073] For example, if a passerby engages in activities such as getting drunk, fighting, or dumping construction waste within the reserve land (primary monitoring area) (abnormal intrusion behavior), it can be determined that the current abnormal intrusion behavior poses a dangerous event to the reserve land.

[0074] Furthermore, in order to reduce misjudgments and not affect the convenience of the existing residents of the reserve land, when a passerby / animal (hereinafter referred to as alien animal) enters the reserve land (i.e., the first-level monitoring area) for only a temporary passerby, for only 10-50 seconds, and whose route directly passes through a small part of the reserve land (without entering the overlapping monitoring area), no abnormal alarm will be triggered for the current intrusion behavior, and the monitoring personnel will not need to make any further early warning plans for such intrusion behavior.

[0075] Specifically, constructing overlapping regulatory zones can enable key monitoring of important resources within the reserve land (such as lakes, minerals, and native rare vegetation) without affecting the convenience of life for the local residents. It can also reduce abnormal alarms caused by routine intrusions and alleviate the workload of regulatory personnel.

[0076] In this embodiment, the step analysis of abnormal intrusion behavior within the primary supervision area of ​​the reserve land specifically includes the following sub-steps:

[0077] Based on abnormal monitoring information, we can obtain and identify unusual animals, and export the identification results, which include residents, animals, and vehicles.

[0078] The first scenario: If the identification result is a resident or an animal, then identify the invasion path of the alien animal into the primary regulatory area of ​​the reserve land and calculate the invasion duration; when the invasion path length or invasion duration exceeds the threshold, then determine that the abnormal invasion behavior has caused a dangerous event to the current reserve land.

[0079] The second scenario: If the identification result is a vehicle, then the intrusion behavior of an alien animal into the primary regulatory area of ​​the reserve land is identified. Intrusion behavior includes driving through, parking, and separation of people and vehicles. When the intrusion behavior is identified as parking or separation of people and vehicles, it is determined that the abnormal intrusion behavior poses a dangerous event to the current reserve land.

[0080] Based on the above scheme, exotic animals entering the reserve land supervision area can be identified, and the types of exotic animals can be initially obtained. This allows for action recognition based on different animal types, thereby improving the accuracy of action analysis.

[0081] Furthermore, it is possible to determine whether abnormal intrusion behavior poses a dangerous event to the current land reserves and construct a risk assessment model; the risk assessment can then be refined based on the following formula:

[0082] Risk value = ∑(hazard coefficient of each intrusion factor × corresponding weight);

[0083] Risk level of intrusion behavior type: Construction damage is marked as A, garbage dumping is marked as B, and arson is marked as C. The risk level can be flexibly set in the system according to the actual degree of harm.

[0084] Intrusion Duration Risk Factor: The risk factor increases by 1 for every 30 seconds exceeding the intrusion duration. Let the duration be t seconds, and the risk factor be...

[0085] The risk factor between the intrusion location and the critical facility is calculated using a Gaussian function. The distance is given as d meters, and the radius of influence of the critical facility is r = 10 meters. Weighting: The weight of the intrusion behavior type is set to M, the weight of the intrusion duration is set to N, and the weight of the distance between the intrusion location and the critical facility is set to X, M+N+X=1.

[0086] The closer to critical facilities, the faster the risk factor increases, which is consistent with the actual risk characteristics; the risk is judged according to the pre-set risk threshold, and if the risk value is greater than or equal to the threshold, it is judged as a dangerous event.

[0087] In summary, based on the judgment in step S300, the following judgment result can be obtained:

[0088] If so, the early warning and response plan will be activated;

[0089] If not, a second assessment will be made of the current abnormal intrusion behavior, and an overlapping regulatory area will be constructed based on the current reserve land area. The temporary intrusion monitoring plan will be implemented to assess the abnormal intrusion behavior in the overlapping regulatory area.

[0090] Step S300: The process of making a secondary judgment on the current abnormal intrusion behavior and constructing an overlapping regulatory area based on the current reserve land area specifically includes the following sub-steps:

[0091] S310: Record the movement trajectory coordinates of alien animals based on the path tracking algorithm, and store the invasion path in the form of a sequence of movement trajectory coordinate points;

[0092] S320: Analysis of the invasion behavior of alien animals and prediction of the predicted invasion path of alien animals;

[0093] Specifically, based on a self-developed multi-sensor fusion path tracking algorithm, the system records the movement trajectory coordinates of invading animals at ultra-high frequency. Abandoning traditional coarse recording methods, it stores the invasion path in real-time as a sequence of movement trajectory coordinates with micro-nano precision, ensuring that every subtle movement and turning point is accurately recorded. Furthermore, leveraging real-time updated behavioral big data and deep neural network models, it analyzes each invasion action of the invading animal in real time, predicting multiple possible subsequent invasion paths. This fully considers the uncertainty of the animal's behavioral trajectory under various complex factors such as environmental stimuli and instinctive drives.

[0094] S330: Constructing overlapping surveillance zones based on predicted intrusion paths;

[0095] Specifically, relying on predicted intrusion paths, an overlapping monitoring area is constructed using a spatial geometric dynamic programming algorithm. This area is not a fixed, rigid pattern, but rather its boundaries, scope, and monitoring level are dynamically adjusted according to the real-time predicted paths. Most importantly, the system's built-in intelligent comparison engine remains vigilant at all times. Once it detects that the actual intrusion path deviates from the predicted intrusion path by more than a threshold and exceeds the currently dynamically adapted overlapping monitoring area, it immediately determines, based on a multi-source risk assessment model, that the intruding animal is highly likely to cause a dangerous event. Simultaneously, it triggers a multi-modal early warning and handling plan, pushing an alarm containing key information such as danger details, precise location, and potential hazard level to the surrounding associated feedback terminals 3, thus comprehensively ensuring the safety of the area.

[0096] In this embodiment, step S330, which involves constructing an overlapping surveillance area based on the predicted intrusion path, further includes the following sub-steps:

[0097] S331: Spatial grid processing of reserve land, with each grid assigned spatial coordinates, terrain attributes, and scene features; terrain attributes can be slope, height difference, etc., and scene features can be markers such as residential buildings, green plants, and water bodies.

[0098] S332: Guided by the predicted invasion path, with the starting point as the core diffusion source, it calculates and outlines the most suitable monitoring range in real time based on the movement speed and turning probability of alien animals, as well as the accessibility and concealment of the surrounding environment.

[0099] First, by comprehensively analyzing the biological habits of different animal species, we can determine their average movement speed range and turning probability distribution under different environments. For example, in relatively open areas without obvious obstacles, their movement speed may be faster and their turning probability relatively lower; while in complex terrain or densely vegetated areas, their movement speed will slow down and their turning probability will increase.

[0100] Next, by combining the topographical attributes (such as slope and elevation difference) and scene features (such as residential buildings, greenery, and water features) of each grid after the reserve land was spatially gridded, the accessibility of the surrounding environment was assessed. In areas with steep slopes, the movement speed of exotic animals would be significantly restricted, resulting in low accessibility. Areas with frequent human activity, such as residential buildings, might deter exotic animals, causing them to avoid the area, thus reducing accessibility accordingly. Furthermore, natural barriers such as water bodies would impede the movement of exotic animals, making accessibility virtually zero.

[0101] Regarding concealment factors, the scene characteristics of each grid are analyzed. For example, areas with dense vegetation can provide better concealment conditions for exotic animals, making them more inclined to move and stay there, thereby affecting their movement paths and the scope of surveillance.

[0102] Based on the comprehensive analysis of the movement speed, turning probability, and accessibility and concealment of the exotic animals, Geographic Information System (GIS) technology and related algorithms are used to calculate and delineate the most suitable surveillance area outline under the current conditions in real time. During the calculation process, the surveillance area outline is dynamically updated to adapt to the real-time movement of the exotic animals and environmental changes. Simultaneously, considering potential uncertainties, the surveillance area outline is appropriately extended to ensure effective coverage of areas where exotic animals may appear.

[0103] For example, using GIS technology and related algorithms to dynamically update the outline of the regulatory area mainly includes steps such as data collection and processing, model building and algorithm selection, and real-time calculation and updating. The following is a detailed introduction:

[0104] (I) Data Collection and Processing

[0105] Alien data: Real-time location, speed, and direction data of alien animals are collected through sensor networks, positioning devices, etc. For example, radar positioning and other positioning methods are used to obtain their coordinate information and speed vector in real time.

[0106] Environmental data: Geographic data of the surrounding environment is obtained using a GIS system, including topography, road and building distribution, as well as attributes such as accessibility and concealment. Accessibility can be determined based on factors such as terrain slope and vegetation cover, while concealment can be derived by analyzing terrain cover and vegetation density.

[0107] (II) Model Building and Algorithm Selection

[0108] Establish a predictive model: Based on the collected data, establish a predictive model for the behavior of exotic animals. For example, using hidden Markov models, combined with factors such as the animal's movement speed and turning probability, predict its possible future movement path.

[0109] Choose a path planning algorithm: Use a suitable path planning algorithm, such as A* algorithm or Dijkstra algorithm, to plan a feasible movement path based on the predicted intrusion path and the accessibility of the environment.

[0110] Determine the method for calculating the surveillance area: Based on the size, activity range, and possible behavioral patterns of the exotic animal, determine an initial method for calculating the surveillance area. For example, draw a circle with the exotic animal's current location as the center and its maximum activity radius as the radius, as the initial surveillance area.

[0111] (III) Real-time calculation and updating

[0112] Real-time data acquisition: Through a data interface, the latest location and environmental changes of exotic animals can be acquired in real time. For example, when an exotic animal moves to a new location, the positioning device immediately transmits the new coordinate data to the GIS system.

[0113] Recalculate the surveillance area: Based on the new data, use GIS spatial analysis functions and related algorithms to recalculate the outline of the surveillance area. For example, if the animal moves faster, the surveillance area may need to be expanded; if it turns into a more concealed area, the shape and size of the surveillance area also need to be adjusted accordingly.

[0114] Dynamic update display: The newly calculated regulatory area outline is displayed on the GIS map in real time, replacing the original outline, thus achieving dynamic updates. Simultaneously, the GIS system can set the update frequency and adjust it reasonably according to actual conditions to balance computing resources and real-time requirements.

[0115] (iv) Considering uncertainty and extension

[0116] Analyze uncertainties: Analyze uncertainties that may affect the behavior of exotic animals and the scope of surveillance, such as weather changes and sudden disturbances. These factors may cause changes in the movement speed and turning probability of exotic animals, or affect the accessibility and concealment of the environment.

[0117] Determine the expansion strategy: Based on the analysis of uncertainty factors, formulate a reasonable expansion strategy. For example, a fixed expansion ratio or distance can be determined based on historical data and experience to expand the regulatory scope outward. Alternatively, the expansion range can be dynamically adjusted according to the real-time level of uncertainty.

[0118] To achieve outward expansion: After each calculation of the regulatory area outline, the area is expanded according to a determined expansion strategy, and the expanded area is displayed on the GIS map. This ensures effective coverage of areas where exotic animals may appear, even under various uncertain conditions.

[0119] S340: If the actual intrusion path deviates from the predicted intrusion path by more than a threshold and exceeds the current overlapping regulatory area, it is determined that the intruding alien animal has caused a dangerous event.

[0120] S350: When a foreign animal is detected in the overlapping regulatory area and after the foreign animal leaves the overlapping regulatory area, detect whether there are any residual foreign objects in the current primary regulatory area and the overlapping regulatory area;

[0121] If present, the foreign animal is marked to prevent it from re-entering the primary or overlapping regulatory areas, and a report on the remaining foreign object to be cleaned is sent.

[0122] The information to be reported regarding residual foreign objects includes the location coordinates of the residual foreign objects, the estimated difficulty of removal, and the recommended removal timeframe.
