Document Type and Number:
WIPO Patent Application WO/2023/228283
Kind Code:
A1
Abstract:
[Problem] The present invention provides an information processing system and the like which enable autonomous movement control of a movable body while seamlessly performing highly accurate self-position estimation in a movement path over the inside and the outside of a structure. [Solution] An information processing system according to the present invention is for self-position estimation of a movable body provided with a receiver for acquiring reception information from a satellite positioning system and with a sensor for acquiring environment information. The information processing system is provided with: a reference coordinate conversion unit for converting both a first coordinate system indicating the reception information and a second coordinate system indicating the environment information into a reference coordinate system based on base point coordinates; and a self-position estimation unit for estimating third self-position information represented by the reference coordinate system, on the basis of first self-position information indicated by the reception information and second self-position information that is calculated by comparing the environment information with reference environment information.
