1. An analysis processing device for performing analysis on body displacements of passengers in a vehicle, comprising:
a calculation unit configured to, based on recognition data including seated and standing positions of the passengers and a number of boarding and alighting passengers in the vehicle, calculate a number of seated passengers and a number of standing passengers;
a period determination unit configured to determine an analysis period of the vehicle according to a function that changes the analysis period depending on the seated and standing positions of the passengers, the function including a standing passenger function associated with passengers in the standing position among the passengers in the vehicle and a predefined standing passenger risk, and a seated passenger function associated with passengers in the seated position among the passengers in the vehicle and a predefined seated passenger risk, the standing passenger function being designed to decrease the analysis period using the calculated number of standing passengers and the predefined standing passenger risk as the number of standing passengers increases, the seated passenger function being designed to increase the analysis period using the calculated number of seated passengers and the predefined seated passenger risk as the number of seated passengers increases.
