Paper Abstract
In order to quickly and exactly detect the subpixel image edge of micro-part, a fast subpixel edge detection method
based on the property of Gaussian blurred edge model is proposed. Firstly, the approximate positioning of edge point
was extracted by double-threshold segmentation; secondly a Zernike moment operator with a mask size of 5×5 was used
to get rid of false edge points and relocate the edge with subpixel accuracy. Experiment results show that the subpixel
accuracy and the running time of the method are 0.16 pixel and 0.94s. Therefore, the method is suitable for online threedimensional
size detection of micro-part.
