The measurement results of acceleration are separated into low-frequency acceleration components and high-frequency acceleration components, and a time-rate-of-changes of attitude angles are calculated based on the measurement results of the attitude angles. After finishing extraction of the high-frequency acceleration components and the low-frequency acceleration components, and finishing calculation of the time-rate-of-changes of attitude angles, the rotation contributing acceleration and translation contributing acceleration are estimated based on the high-frequency acceleration components, the low-frequency acceleration components, the attitude angles and the time-rate-of-change of attitude angles. As a result, a translation contributing acceleration which contributes to a translational movement of a moving object, and a rotation contributing acceleration which contributes to a rotational movement of the moving object are estimated with improved accuracy."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for acceleration estimation, acceleration estimating apparatus, and mobile terminal","description":"Acceleration and attitude angles are measured by sensors mounted on a moving object and the measurement results are collected.
