MOBILE BODY ACTION ANALYSIS DEVICE

摘要

PROBLEM TO BE SOLVED: To detect a mobile body action pattern and abnormal action of a mobile body with high accuracy with a small calculation amount without previously registering the mobile body action pattern for deciding the abnormal action. SOLUTION: This mobile body action analysis device has: a mobile body position time series data detection device 1 for detecting position time series data in each the mobile body about a plurality of the mobile bodies; a mobile body position time series data storage means 31 for previously storing the position time series data detected by the mobile body position time series data detection device 1; and a mobile body abnormal action detection means 32. The mobile body abnormal action detection means 32 models the position time series data by a hidden Markov model in each the mobile body, and collates prescribed similarity between the hidden Markov model corresponding to one mobile body and the hidden Markov model corresponding to the plurality of the other mobile bodies with a predetermined criterion to decide whether the action of the one mobile body is abnormal or not.
