Research on the Size Measurement of Shaft Parts Based on Image Processing

Abstract:

non-contact measurement of shaft component realizes dynamic measuring ,which bases on image measurement technology.After the image of shaft is obtained,Sobel operator is used for preliminary locating to image edge,on basis of this ,discrete points of image edge are fitted by least square method for achieving edge subpixel location.By precision analysis, size solution method is acquired when the error is minimum;After calibration coefficient k is gained, the part size is correctly calculated. By experiment, it shows that measurement precision is improved effectively and measurement error is less than ±20μm when resolution of CCD camera is 1392×1040 and its pixel size is 4.65μm.
