Abstract
Official abstract text for this publication.
A sensor unit is installed to a target object and detects a given physical amount. A data acquisition unit acquires output data of the sensor unit in a period including a first period for which a real value of a value of m time integrals of the physical amount is known and a second period that is a target for motion analysis. An error time function estimating unit performs m time integrals of the output data of the sensor unit and estimates a time function of an error of a value of the physical amount detected by the sensor unit with respect to the real value of the value of the physical amount detected by the sensor unit based on a difference between a value of m time integrals of the output data and the real value for the first period.
First claim
Opening claim text (preview).
What is claimed is: 1. A motion analyzing apparatus comprising: a data acquisition unit that acquires output data of a sensor unit in a period including a first period for which a real value of a value of m time integrals (here, m is an integer equal to or greater than one) of the physical amount is known and a second period that is a target for motion analysis; a data correcting unit that corrects a value of m time integrals of the output data for the second period based on a d…
