Abstract

The embodiment of the invention provides a method, device and system for tracking potential infected persons in public places during epidemic situations, and the method comprises the following steps:determining time nodes of activities of confirmed persons in the public places and position information matching the time nodes according to the related information of the confirmed persons; searchingpotential infected persons by means of video frame data provided by video monitoring equipment in public places on the basis of an infectious disease transmission mechanism according to time nodes and position information of the confirmed persons in the public places; tracking potential infected persons based on a multi-target tracking technology, and confirming the identities of the potential infected persons by combining public place key node time. According to the invention, the potential infected persons associated with the diagnosed persons in the public places are actively searched, andthe identities of the potential infected persons are determined. Through data tests, the precision of the invention can reach 80% or above, searching and confirmation of potential infected persons inpublic transport places are achieved to a large extent, and the invention plays an important role in prevention and control of epidemic situations.

Description

technical field [0001] The present invention relates to the technical field of target tracking in dense public areas, and in particular to a method, device and system for tracking potential infected persons in public places during an epidemic. Background technique [0002] During the spread of the epidemic, it is assumed that there are three kinds of people, namely A, B and C. If C and A have a clear understanding, after A is diagnosed as a patient, it is easy to determine who C has been in contact with. But assuming that A encounters B whom he does not know all his life in a public place (such as an airport, a station, or a pier during a journey), A does not know the existence of B, and B does not know the existence of A either. However, after several days of virus incubation period, it was found that A was a virus-infected person. Then A has been in contact with B in public places and becomes a potential infected person. A potential infected person like B is very dangero...
