Document Type and Number:
Japanese Patent JP7078116
Kind Code:
B2
Abstract:
According to the present disclosure, there is provided an indoor position estimation apparatus (100) including: a first acquisition unit (111) that acquires a target magnetic pattern indicating a result obtained by repeatedly measuring an indoor magnetic field by a position estimation target including a magnetic sensor; a first extraction unit (112) that extracts predetermined frequency components from the target magnetic pattern; and an estimation unit (113) that obtains an estimation result of an indoor position of the position estimation target by inputting data on the extracted frequency components into an estimation model obtained by machine learning.
