Title:
MOVEMENT LINE INFORMATION GENERATION SYSTEM, MOVEMENT LINE INFORMATION GENERATION METHOD AND MOVEMENT LINE INFORMATION GENERATION PROGRAM
Document Type and Number:
WIPO Patent Application WO/2013/128852
Kind Code:
A1
Abstract:
The present invention estimates the correspondence relationship between the trajectory of a mobile object and identification information relating to the mobile object even when the accurate correspondence relationship between the trajectory of the mobile object and the identification information relating to the mobile object may not be able to be specified, and quantifies the degree of ambiguity of the correspondence relationship. With respect to each trajectory connection candidate, an identification information association means (93) associates likely mobile object identification information with each of individual trajectory connections included in the trajectory connection candidate. From the result of the association between the trajectory connections and the mobile object identification information, regarding each individual trajectory information and with respect to each individual mobile object identification information, an association tendency numerical conversion means (94) converts into numbers the tendency of the number of times the trajectory information and the mobile object identification information are associated with each other. On the basis of the result thereof and with respect to each trajectory information, an association score calculation means (95) calculates, regarding each mobile object identification information, an association score indicating the degree of ambiguity of a correspondence relationship in which the trajectory indicated by the trajectory information corresponds to the trajectory of the mobile object identified by the mobile object identification information.
