A method for calibrating parameters includes a measurement step that obtains measurement data by scanning a defined surface; a correction step that obtains corrected data by correcting the measurement data based on the parameters; a determination step that calculates a roundness of the corrected data and determines whether the calculated roundness is equal to or less than a predetermined value; and an adjustment step that increases or reduces at least one of the parameters when the roundness is determined to be greater than the predetermined value, and the correction step, the determination step, and the adjustment step are repeated until the roundness is determined to be equal to or less than the predetermined value.
