Document Type and Number:
Japanese Patent JP7436257
Kind Code:
B2
Abstract:
A behavior recognition server (1) has: a sensor information acquisition unit (11) that acquires, from a collection of sensors (2) for detecting an observee (2u), sensor information of each of the sensors (2); a sensor information conversion unit (11T) that, on the basis of reaction time when the observee (2u) is detected in the sensor information in a chronological order, converts the sensor information into a probability density function of a temporal direction where the reaction time is set as the maximum value; a behavior classification unit (14) that classifies the behavior of the observee (2u) at each time; and a behavior output unit (17) that converts the classified behavior of the observee (2u) into data and outputs the data.
