MEASURING APPARATUS, MEASURING METHOD AND MEASURING PROGRAM
The attitude of an excavating part during excavation is accurately measured. A measuring apparatus of the present invention comprises an attitude estimating part and a phase correction amount calculating part. The phase correction amount calculating part calculates an offset between a gravity tool face and a magnetic force tool face, and sets the calculated offset as an estimated offset. The attitude estimating part sets the gravity tool face based on the acceleration data as a measured gravity tool face, the magnetic force tool face based on the magnetic field data as a measured magnetic force tool face, a difference between an offset between the measured gravity tool face and the measured magnetic force tool face and the estimated offset as a phase correction amount, and data obtained by correcting the magnetic field data with the phase correction amount as corrected magnetic field data, and determines the attitude based on the acceleration data and the corrected magnetic field data.
