Research and Application of Edge Feature Extraction of Digital Image by Least Square Method with Weight Function

LIN Hai-bo;PAN Wan-gui;School of Mechanical Engineering,Taizhou Vocational & Technical College;State Key Laboratory of CAD & CG,Zhejiang University;  
A rapid and accurate contours fitting method for backlight image of thin and complex mechanical parts w ith clear edge is presented. The large number of sub pixel edge coordinate data w as divided into the basic geometric elements such as line and arc segments using the Ramer algorithm. The least square method w as improved to eliminate the impact from the outliers based on distance betw een discrete points and the pre fitted curve. The arcs and straight lines is fitted robust,then circle diameter and center distance w as calculated. The measurement results of gear pump intermediate part show that,this method can used in geometry precision measurement of thin parts w ith many holes quickly and accurately. This method is instructive for the further research and application in vision measurement.
