Abstract
A measurement apparatus includes: a data acquisition unit that acquires position time series data indicating a position of a contact unit during a measurement period when the contact unit is pressed into a measurement target, and pressure time series data indicating pressure applied to the contact unit during the measurement period, the contact unit being included in a measurement unit that contacts the measurement target; and a state identification unit that identifies an internal state parameter of the measurement target by analyzing the pressure time series data and the position time series data.
Claims12
A measurement apparatus that measures an internal state parameter of a measurement target, the measurement apparatus comprising:
- a contact unit included in a measurement unit that contacts the measurement target;
- a storage unit that stores reference data or an arithmetic expression indicating a relationship between (i) reference position time series data indicating a position of the contact unit while the contact unit is being pressed into a reference object, (ii) reference pressure time series data indicating pressure applied to the contact unit while the contact unit is being pressed into the reference object, and (iii) an internal state parameter of the reference object;
- a data acquisition unit that acquires position time series data indicating a position of the contact unit during a measurement period when the contact unit is pressed into the measurement target and pressure time series data indicating pressure applied to the contact unit during the measurement period;
- and
- a state identification unit that identifies an internal state parameter of the measurement target by analyzing the position time series data and the pressure time series data using the reference data or the arithmetic expression.
A measurement method implemented by a computer, the method comprising:
- acquiring position time series data indicating a position of a contact unit during a measurement period when the contact unit is pressed into a measurement target, and pressure time series data indicating pressure applied to the contact unit during the measurement period, the contact unit being included in a measurement unit that contacts the measurement target;
- and
- identifying an internal state parameter of the measurement target by analyzing the position time series data and the pressure time series data using reference data or an arithmetic expression indicating a relationship between (i) reference position time series data indicating a position of the contact unit while the contact unit is being pressed into a reference object, (ii) reference pressure time series data indicating pressure applied to the contact unit while the contact unit is being pressed into the reference object, and (iii) an internal state parameter of the reference object.
A non-transitory computer-readable storage medium storing program for making a computer perform:
- acquiring position time series data indicating a position of a contact unit during a measurement period when the contact unit is pressed into a measurement target, and pressure time series data indicating pressure applied to the contact unit during the measurement period, the contact unit being included in a measurement unit that contacts the measurement target;
- and
- identifying an internal state parameter of the measurement target by analyzing the position time series data and the pressure time series data using reference data or an arithmetic expression indicating a relationship between (i) reference position time series data indicating a position of the contact unit while the contact unit is being pressed into a reference object, (ii) reference pressure time series data indicating pressure applied to the contact unit while the contact unit is being pressed into the reference object, and (iii) an internal state parameter of the reference object.
