Title:
MOVEMENT ESTIMATION DEVICE
Document Type and Number:
Japanese Patent JP2023069665
Kind Code:
A
Abstract:
To output information that satisfies a predetermined standard regarding a user who has moved.SOLUTION: A movement estimation device 1 has: an acquisition part 11 for acquiring movement number information regarding the number of users for each movement time as a time when the movement is started as the number of users who have moved between an area A1 and an area A2 within a predetermined time width; and an output part 13 for performing Fourier transform of a function corresponding to the movement number information acquired by the acquisition part 11, performing inverse Fourier transform of frequency components that satisfy a predetermined standard from among Fourier-transformed functions, and outputting information based on the inverse-Fourier-transformed functions. The output part 13 may perform inverse-Fourier transform of components that are less than a predetermined frequency from among Fourier-transformed functions. The output part 13 may output information based on inverse-Fourier-transformed functions as information regarding a user who has moved by using the public transportation.SELECTED DRAWING: Figure 3
