Abstract
A laser measurement calibration method is adapted to establish in a software program and executes the following steps after read by a computer: measuring a standard calibration element with a contact sensing device to obtain a measurement value; measuring the standard calibration element with at least one non-contact sensing device to obtain at least one surface distance value of the standard calibration element; calculating a calibration value according to the measurement value of the standard calibration element and the at least one surface distance value of the standard calibration element; measuring an object to be measured with the at least one non-contact sensing device to obtain at least on surface distance value of the object to be measured; and calculating a measurement value of the object to be measured according to the calibration value and at least one surface distance value of the object to be measured.
