| Abstract: | The authors introduced the processing procedure of profile data point based on contact-type scanning measurement in detail,including noise filtering,downsize filtering,smoothing,curve segmentation and other links,and then fitted the contour line by the method of the least squares.Through actual project application,it has been found that the effect of this method of date processing is good and can get contour line meeting the requirement on accuracy. |
