Correction method, computer-readable recording medium storing computer-executable correction programs and measurement apparatus

A computer-readable recording medium storing a computer-executable correction program for correcting a measurement error in data obtained when a stylus tip of a measurement apparatus that moves following the height of a workpiece traces the workpiece along a measurement axis,

• the measurement error having occurred due to stylus movement in a correction target plane defined by the measurement axis and height directions, and the measurement error targeting a shift of the position of the stylus tip, corresponding to the position of the stylus tip in the height directions in the correction target plane,
• the program causing a computer to execute:
• a calibration measurement process of obtaining calibration measurement data that includes shift information on the position of the stylus tip, corresponding to the position of the stylus tip in the height directions while the stylus is moved in the correction target plane;
• and
• a correction-parameter setting process of simultaneously obtaining a correction parameter value optimal to correct the shift information on the position of the stylus tip, included in the calibration measurement data obtained in the calibration measurement process, for each of a predetermined number of sectors obtained in advance by dividing a measurement range in the height directions.
