Abstract

The invention discloses an epidemic situation close contact person trajectory determination method, system and device and a storage medium, and the method comprises the steps: obtaining road network topology information and first positioning information of a plurality of persons, and determining the first trajectory data of the plurality of persons according to the road network topology information and the first positioning information; establishing an R-Tree spatial index according to the first trajectory data; acquiring a preset epidemic situation personnel trajectory, and matching in the R-Tree spatial index according to the epidemic situation personnel trajectory to obtain a trajectory of a person closely contacted with the epidemic situation. According to the invention, space positioning information and a road network topological structure are combined to determine the trajectory data of the personnel, the real-time performance and accuracy of trajectory tracking are improved, the R-tree spatial index is established, and the epidemic situation trajectory data are quickly queried and matched for retrieval, so that the trajectory of the personnel in close contact with the epidemic situation is quickly and accurately searched, the method improves the efficiency and accuracy of trajectory tracking of people in close contact with epidemic situations, and can be widely applied to the technical field of personnel trajectory tracking.

Description

technical field [0001] The present invention relates to the technical field of personnel trajectory tracking, in particular to a method, system, device and storage medium for determining the trajectory of close contacts of an epidemic. Background technique [0002] Close contact tracking can help users self-judge their contact history with risk personnel (infectious virus carriers, potential personnel endangering public safety, etc.), which provides strong technical support for personnel management and control in emergencies, reducing Unnecessary harm caused by risk personnel to ordinary personnel (segregation of personnel, economic loss from business closures). Therefore, close contact tracing is becoming more and more important in modern social management, bringing convenience to daily life. [0003] At present, most of the tracking of close contacts of the epidemic situation is to determine the relevant personnel they may come into contact with through the movement traje...
