Abstract
A digitizing method in which a distance from a model surface is measured and stored at regular intervals of time or distance to obtain digital profile data of the model. A specified profile for correction is provided on a part of the model, and by using the specified mode, correction data such as a distance correction coefficient is obtained before carrying out the digitizing. Digitizing data obtained by carrying out the digitizing is corrected by the correction data. The correction data is obtained based on the material and surface condition of the actual model, and therefore, the digitizing data can be accurately corrected.
Claims1
A method for measuring a distance from a surface of a model, comprising the steps of:
- providing a specified profile on a portion of the model, for use in obtaining correction data;
- obtaining the correction data based on the specified profile, said correction data obtaining step including calculating a zero point correction amount and a mean value of a correction coefficient;
- measuring a distance from the surface of the model to obtain measured data;
- and
- obtaining digitized data based upon the obtained measured data and the correction data.
