Title:
MOVING BODY BEHAVIOR INFORMATION ACQUISITION METHOD, MOVING BODY BEHAVIOR INFORMATION ACQUISITION DEVICE, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2022/091650
Kind Code:
A1
Abstract:
This moving body behavior information acquisition method comprises: acquiring observed velocity values for a moving body on the basis of a first interval; storing the acquired observed velocity values in association with corresponding time information; and acquiring acceleration values in the travel direction of the moving body by, on the basis of the corresponding time information, inputting the observed velocity values into a state space model in which velocity state value variation per unit of time constitutes acceleration values in the travel direction, the observed velocity values are velocity state values with values generated according to a first distribution added thereto, and the variation in the value of the acceleration in the travel direction per unit of time follows a second distribution.
