Motion analyzing apparatus
First Claim
1. A motion analyzing apparatus comprising:
- a sensor unit that is installed to a target object and detects a physical amount;
a data acquisition unit that 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 (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;
an error time function estimating unit that performs m time integrals of the output data 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 based on a difference between a value of m time integrals of the output data and the real value for the first period;
a data correcting unit that corrects a value of m time integrals of the output data for the second period based on an estimation result of the error time function estimating unit; and
a motion analysis information generating unit that generates motion analysis information of the target object based on the value of the m time integrals for the second period that is corrected by the data correcting unit.

Abstract
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.
