Space trajectory big data analysis-based person management and control method and system

Abstract

The invention relates to the technical field of person behavior pattern analysis, and particularly relates to a space trajectory big data analysis-based person management and control method and a system. The method comprises steps: trajectory data of important persons are extracted, and according to the important person specified by a user, a space region or a time range, trajectory address information of the person is queried from multiple databases according to an ID number; according to the name of the trajectory address, corresponding geographic latitude and longitude coordinates are found out from the address database, and finally each important person can be presented to be a corresponding geographic coordinate sequence; vectorization of the trajectory data is carried out; latent semantic analysis is carried out on the trajectory mode, singular value decomposition is carried out on a matrix, the matrix is rebuilt through dimension reduction, and the rebuilt matrix is the latent semantic matrix of the important person trajectory mode; the important persons are clustered, and a management and control task is assigned according to a clustering processing result. Compared with the prior art, potential contact of the important persons is dug in massive person trajectory data, and management and control tasks are assigned reasonably.

Description

Technical field: [0001] The invention relates to the technical field of personnel behavior pattern analysis, in particular to a personnel management and control method and system based on spatial trajectory big data analysis that can cluster a group of key monitoring personnel according to spatial activity trajectories. Background technique: [0002] With the popularity of the second-generation resident ID card, the application of the second-generation card reader has gradually penetrated into all walks of life, such as Internet cafes, hotels, banks, railway stations, etc. Therefore, the personnel trajectory information data based on the second-generation card is also growing explosively. In the public security department, it is often necessary to track and control some specific key personnel through ID cards. The management and control of key personnel is an important part of public security intelligence work, and it is also the focus of the grassroots police on the manage...

Problems solved by technology

[0005] At present, there have been a lot of research results on personnel trajectory analysis in academia, but most of these research results are too theoretical and have not been combined with actual application scenarios for specific optimization, especially for the analysis of police criminal behavior.
