Behavior recognition server, behavior recognition system, and behavior recognition method

摘要

PROBLEM TO BE SOLVED: To suppress a decrease in recognition accuracy from sensor information including false detection data. An action recognition server 1 has a sensor information acquisition unit 11 that acquires sensor information for each sensor 2 from a set of sensors 2 that detect an observer 2u, and an observer among time-series sensor information. Based on the reaction time when 2u is detected, the sensor information conversion unit 11T that converts the sensor information into a probability density function in the time direction that maximizes the reaction time, and each based on the converted sensor information. It has an action classification unit 14 that classifies the behavior of the observed person 2u at the time, and an action output unit 17 that converts the classified behavior of the observed person 2u into data and outputs it. Further, the sensor information conversion unit 11T transfers the sensor information to the probability density function in the spatial direction that maximizes the reaction time based on the reaction location where the observed person 2u is detected in the time series sensor information.
