<P>PROBLEM TO BE SOLVED: To provide a data processing method and program capable of performing a data thinning out processing for performing accurate smoothing when identifying a curve or curved surface model. <P>SOLUTION: Inter-data distances between the respective K pieces, for instance, of inputted data are calculated (step S1), the minimum value is selected, and a data pair which gives the minimum inter-data distance is extracted (step S2). Then, one of the extracted data pair is deleted and a thinning out processing is executed (step S3). Thereafter, the minimum inter-data distance of a data group after the thinning out processing of the arrangement condition of the data remaining after the thinning out processing or the like is calculated as an evaluation index (step S4), the thinning out processing is continued or the thinning out processing is discontinued on the basis of the evaluation index, and the curved surface model is generated by using the processed data. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
