Abstract

Abstract A digitizing method which comprises measuring the distance to the surface of a model, storing the distance for a perdetermined period of time or for every predetermined distance, and finding digital profile data of the model. A normal profile for correction is provided in a portion of the model (13), correction data such as correction coefficients of the dis­tance are found by using the normal profile prior to initiating the digitizing, and digitizing data obtained by executing the digitizing are corrected using the correction data. The correction data are found from the material and the surface condi­tion same as those of the model, and make it possible to properly correct the digitizing data.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 100 words
A digitizing method in which a distance from a surface of a model is measured and stored at regular intervals of time or distance to obtain digital profile data of the model, comprising: providing a specified profile for correction on a part of the model; issuing a measurement command and obtaining correction data such as a distance correction coefficient, a zero point correction value, and the like from a command value and an actually measured value, by using said specified profile, before carrying out a digitizing; and correcting digitizing data obtained by carrying out the digitizing, by said correction data.
Claim 2
Dependent Claim 100 words
A digitizing method in which a distance from a surface of a model is measured and stored at regular intervals of time or distance to obtain digital profile data of the model, comprising: providing a specified profile for correction on a part of the model; issuing a measurement command and obtaining correction data such as a distance correction coefficient, a zero point correction value, and the like from a command value and an actually measured value, by using said specified profile, before carrying out a digitizing; and correcting digitizing data obtained by carrying out the digitizing, by said correction data.
Claim 3
Dependent Claim 23 words
A digitizing method according to claim 1, wherein said distance to the surface of the model is measured by a laser range finder.
