Description

Technical Field

[0001] The present invention relates to the technical field of public security prevention and control, and particularly to a method, device, equipment and storage medium for predicting public security prevention and control within a regional scope. Background Art

[0002] Existing rural public security prevention and control usually adopts a public security management solution based on video surveillance. By setting video surveillance devices at key positions, when rural public security problems are found, corresponding responsible persons are dispatched to handle relevant problems.

[0003] However, in practice, the existing video surveillance devices and the setting of public security prevention and control responsible persons can only be monitored when or after rural public security incidents occur, and cannot play a preventive role before the incidents occur. The achieved public security maintenance and management effects are not good. If serious public security incidents occur, even if the incidents are monitored, the resulting personal and property losses cannot be recovered. In some solutions, it is proposed to identify incidents such as gatherings and fights by monitoring the gathering of people. However, in the rural scenario, the daily life of residents usually has regular gathering behaviors (such as going to the market, weddings and funerals, and joint labor, etc.), resulting in a high false alarm rate for predicting public security incidents by monitoring the gathering of people. This causes a large workload for public security prevention and control responsible persons or patrol personnel, and further affects the vigilance towards public security management. When real public security incidents occur, the solution plan cannot be triggered quickly and accurately enough.

[0004] Therefore, how to provide a public security prediction and protection method applicable to the rural regional scope, with high detection accuracy and low false alarm rate, is a technical problem that urgently needs to be solved. Summary of the Invention

[0053] Obtain surveillance videos within the region, extract face information from the surveillance videos, and generate a personnel gathering event within the region;

[0055] The specific embodiments of the present invention applied to the device are basically the same as the embodiments of the following public security prevention and control prediction method within a region, and will not be elaborated here.

[0056] An embodiment of the present invention provides a public security prevention and control prediction method within a region. Refer to Figure 2 , Figure 2 which is a schematic flowchart of the embodiment of the public security prevention and control prediction method within a region of the present invention.

[0057] In this embodiment, the public security prevention and control prediction method within the region includes the following steps:

[0058] S100: Obtain a set of personnel conflict events within a region; wherein, the set of personnel conflict events includes several personnel conflict events, and each personnel conflict event includes a personnel conflict subject and conflict-related information;

[0059] S200: Based on the set of personnel conflict events, generate a personnel conflict relationship graph within the region;

[0061] S400: Generate a public security prevention and control prediction result based on the personnel conflict relationship diagram and the personnel gathering event.

[0062] It should be noted that in the prior art, rural public security prevention and control usually adopts a public security management solution based on video surveillance. By setting video surveillance devices at key locations, when rural public security problems are discovered, the corresponding responsible persons are dispatched to handle relevant problems. However, in practice, the existing video surveillance devices and the setting of public security prevention and control responsible persons can only be monitored when or after rural public security incidents occur, and cannot play a preventive role before the incidents occur. The achieved public security maintenance and management effects are not good. If serious public security incidents occur, even if the incidents are monitored, the resulting personal and property losses cannot be recovered. In some solutions, it is proposed to identify incidents such as gathering and fighting by monitoring personnel gatherings. However, in the rural scenario, the daily lives of residents usually have regular gathering behaviors (such as going to the market, weddings and funerals, and joint labor, etc.), resulting in a high false alarm rate in predicting public security incidents through personnel gatherings, causing a large workload for public security prevention and control responsible persons or patrol personnel, and further affecting the vigilance in the face of public security management. When a real public security incident occurs, the solution plan cannot be triggered quickly and accurately enough.

[0063] To solve the above problems, in this embodiment, by obtaining the personnel conflict event set within the regional scope, a personnel conflict relationship diagram is established based on this, and the personnel gathering events extracted from the surveillance video are filtered and public security prevention and control predicted using this personnel conflict relationship diagram. It can comprehensively consider the influence of personnel conflict events and normal rural gathering activities on public security prevention and control prediction, improve the management intensity of rural public security prevention and control, and solve the technical problem of high false alarm rate in the current public security prevention and control prediction within the regional scope.

[0064] In a preferred embodiment, the step of obtaining the personnel conflict event set within the regional scope specifically includes: obtaining the personnel conflict event information uploaded by the resident side, extracting the personnel conflict subjects and conflict correlation information in the personnel conflict event information to generate personnel conflict events; transmitting the personnel conflict events to the audit side, and when receiving the confirmation information feedback from the audit side, writing the personnel conflict events into the personnel conflict event set according to the confirmation information.

[0065] Among them, the contradictory correlation information includes the occurrence event of the contradictory event and the content of the contradictory event; the step of transmitting the personnel contradictory event to the audit end and writing the personnel contradictory event into the personnel contradictory event set according to the confirmation information when receiving the confirmation information feedback from the audit end specifically includes: transmitting the personnel contradictory event to the audit end, so that the staff of the audit end verifies the contradictory event according to the personnel contradictory subject, the occurrence event of the contradictory event and the content of the contradictory event, and feeds back the confirmation information according to the verification result; among them, the confirmation information includes the contradictory event level; when receiving the confirmation information feedback from the audit end, write the personnel contradictory event into the personnel contradictory event set according to the contradictory event level in the confirmation information.

[0066] Furthermore, the contradictory event level includes a non-contradictory event level and several fact contradictory event levels from low to high; the step of writing the personnel contradictory event into the personnel contradictory event set according to the contradictory event level in the confirmation information specifically includes: when the contradictory event level is the non-contradictory event level, ignore the personnel contradictory event corresponding to the received confirmation information; when the contradictory event level is the fact contradictory event level, add the contradictory event level to the personnel contradictory event and write the personnel contradictory event into the personnel contradictory event set.

[0067] In this embodiment, through the personnel contradictory event information uploaded from the resident side, the resident side can be a reporting channel for personnel contradictory events provided by the government or the responsible unit to the public. When residents see or learn about personnel contradictory events in the village during their daily lives, they can report the personnel contradictory event information through this channel. After being confirmed by the audit end, the personnel contradictory event is written into the personnel contradictory event set for calling relevant information about personnel relationships during public security prevention and control prediction. It should be noted that when the audit end conducts the audit of contradictory events, it is necessary to classify them by level (for example, for the contradiction of ordinary quarrels between villagers, its level is classified as level one; for the contradiction involving finances, its level is classified as level two; for the contradiction involving physical pushing and shoving, its level is classified as level three, and so on, covering all possible behavioral characteristics of contradictions). Thus, by quantifying contradictions, quantitative contradiction data can be provided during public security prevention and control prediction, improving the accuracy of public security prevention and control prediction and reducing the false alarm rate.

[0068] In a preferred embodiment, the steps of generating a personnel conflict relationship diagram within a region based on the set of personnel conflict events specifically include: extracting the personnel conflict subjects of each personnel conflict event in the set of personnel conflict events, and establishing an initial personnel conflict relationship diagram based on the personnel conflict subjects; wherein, the personnel conflict relationship diagram includes a number of personnel conflict subjects as nodes and connection lines connecting the personnel conflict subjects; according to the conflict event level of each personnel conflict event, assigning a conflict event level to the connection lines connecting the personnel conflict subjects in the initial personnel conflict relationship diagram to generate the final personnel conflict relationship diagram within the region.

[0069] Among them, the steps of obtaining a surveillance video within a region, extracting the face information in the surveillance video, and generating a personnel gathering event within the region specifically include: obtaining a surveillance video within the region, extracting the face information in the surveillance video, recording the activity trajectory and current moving speed of each person in the personnel trajectory database according to the position information and time information of the face information; judging whether a personnel gathering event occurs within the region based on the activity trajectory and current moving speed of each person; wherein, the personnel gathering event is: with the current moving speed, at least a preset number of gathering personnel's activity trajectories satisfy that the time difference for reaching the target position point is less than a preset time.

[0070] On this basis, the steps of generating a public security prevention and control prediction result according to the personnel conflict relationship diagram and the personnel gathering event specifically include: obtaining a normal gathering event uploaded by the resident side; wherein, the normal gathering event includes a normal gathering location and a normal gathering time; based on the normal gathering location and the normal gathering time, performing a normal gathering event elimination action on the personnel gathering events; wherein, the normal gathering event elimination action is to eliminate the personnel gathering events with the same gathering location and gathering time within the error range; extracting all the gathering personnel in each of the personnel gathering events after elimination, and using the gathering personnel to match the conflict event levels of each group of two personnel conflict subjects with connection lines in the personnel conflict relationship diagram; based on the conflict event levels, querying the corresponding public security event contribution scores in the conflict event level and public security event contribution score comparison table, and calculating the sum of the public security event contribution scores of each personnel gathering event according to the public security event contribution scores of each group of two personnel conflict subjects with connection lines; when the sum of the public security event contribution scores exceeds a preset public security event contribution score threshold, generating a public security prevention and control warning signal; wherein, the public security prevention and control warning signal records the gathering location and gathering time of the personnel gathering event.

[0071] In this embodiment, first, a personnel conflict relationship graph is generated using the personnel conflict event set, with personnel as nodes and the conflicts between personnel as connection lines. After that, based on the personnel activity trajectories obtained through video surveillance, all personnel gathering events within the area range are extracted according to the activity trajectories. Finally, for the personnel in all personnel gathering events, the conflict event levels between them are searched in the personnel conflict relationship graph, and the corresponding public security event contribution scores are matched using the conflict event levels. Thus, by statistically comparing the sum of the public security event contribution scores between all personnel in each personnel gathering event with a preset public security event contribution score threshold, when the sum of the public security event contribution scores exceeds the preset public security event contribution score threshold, it is determined that there may be a public security event. At this time, a public security prevention and control warning signal is generated, enabling patrol personnel or responsible persons to carry out corresponding public security management according to the gathering location and gathering time in the public security prevention and control warning signal.

[0072] In this embodiment, a method for predicting public security prevention and control within a regional scope is provided. By obtaining the personnel conflict event set within the regional scope, a personnel conflict relationship graph is established, and the personnel gathering events extracted from the surveillance video are filtered and public security prevention and control predicted using this personnel conflict relationship graph. It can comprehensively consider the influence of personnel conflict events and normal rural gathering activities on public security prevention and control prediction, improve the management strength of rural public security prevention and control, and solve the technical problem of high false alarm rate in current public security prevention and control prediction within the regional scope.

[0073] Refer to Figure 3 , Figure 3 which is the structural block diagram of the embodiment of the public security prevention and control prediction device within the regional scope of the present invention.
