A passenger traveling group identification method and system based on space-time constraints

Abstract

The present application relates to the technical field of data processing, and particularly relates to a passenger traveling group identification method and system based on space-time constraints; the method comprises the following steps: obtaining the passing records of multiple passengers; receiving constraint parameters; according to the analysis time period, the port range and the entry and exit direction, screening target passing records from the passing records and extracting passenger identifiers to form a candidate passenger set; traversing each passenger in the candidate passenger set as a reference passenger, taking the time window threshold as a constraint, and counting the traveling passengers who pass through the same port in the time window threshold with the reference passenger; when the number of traveling passengers reaches the traveling passenger threshold and the number of occurrences in the analysis time period reaches the occurrence threshold, identifying the group containing the reference passenger and the traveling passengers as a traveling group; outputting the group number and the group member list of each identified traveling group; the present application realizes the intelligent identification of dynamic and concealed traveling groups in the immigration inspection scene.
