Embodiment 1

[0051] In a specific embodiment, the time-space analysis method for public security cases based on operator data further includes the steps,

[0052] S40: Verify the similarity between the suspect's action trajectory and the case's action trajectory, and if the similarity meets a certain threshold, list him as the final suspect and obtain a final list of suspects.

[0053] In this embodiment, the location information of the suspect at the time of the crime will be obtained based on the operator data, and the location information will be used to generate an action trajectory, which will then be compared with the case action trajectory. If the two trajectories have a high degree of similarity, their Listed as the final suspect, the similarity threshold here is 90% similarity.

Embodiment 2

[0055] In a specific embodiment, the step S30 specifically includes,

[0056] S31: Screen out the operator customers who appear within the error range of the crime location within the error range of the time of the crime;

[0057] S32: Screen out the operator customers who match the action track of the case within the time error range of the case, and obtain a list of suspects.

[0058] In this embodiment, the crime location is a fixed location value, including longitude and latitude information. The error range of the crime location is to make up for the error of the positioning accuracy of the base station, and the error range of the crime time is to make up for the difference between the time of the crime and the time of committing the crime. error.

Embodiment 3

[0060] see figure 2 , in a specific embodiment, the step S40 specifically includes,

[0061] S41: Obtain the location information of the suspect within the error range of the incident time;

[0062] S42: Form the suspect's action track according to the suspect's location information;

[0063] S43: Compare the similarity between the action trajectory of the suspect and the action trajectory of the case, list the suspects whose similarity is greater than a certain threshold as the final suspects, and obtain a list of final suspects.

[0064] In this embodiment, the latitude and longitude information of the suspect is obtained, and the latitude and longitude information is connected on the map according to the time sequence of the crime, and the action trajectory of the suspect is sequentially connected, and the action trajectory of the suspect is compared with the action trajectory of the case, which is satisfied. Suspects with similarity requirements are listed as final susp...

Abstract

The invention provides an operator data-based public security case time-space analysis method and apparatus. The method comprises the steps of obtaining occurrence information of serial cases, whereinthe occurrence information comprises occurrence time, occurrence places, occurrence time error ranges and occurrence place error ranges of the cases; according to a sequence of the occurrence time ofthe serial cases, sequentially connecting the occurrence places into a case action track on a map; and screening out operator clients occurring on the case action track in the occurrence time, and classifying the operator clients as suspects, thereby obtaining a suspect list. The method is based on operator data, so that the coverage range is wide and the blind area is small; the operator clientssatisfying the case action track are screened and classified as the suspects, so that the suspect check range is effectively narrowed, the case solving time is shortened, and the case solving efficiency and quality of public security organs are improved.

Description

technical field [0001] The invention relates to a method and device for time-space analysis of public security cases, in particular to a method and device for time-space analysis of public security cases based on operator data. Background technique [0002] With the trend of professionalization, teamwork, and migration of crimes becoming more and more obvious, among all kinds of criminal cases, the series of cases of property infringement account for a considerable proportion. The frequent occurrence of this series of cases has the most extensive impact on social security and the people The impact of the masses is the most specific and direct, and has become a prominent issue affecting social security across the country. How to quickly detect such cases has become the focus of social attention. [0003] The traditional means of detecting public security cases is to conduct on-site investigations, obtain video recordings, and interrogate witnesses, etc. The disadvantages are ...
