In order to improve the edge detection precision of miniature parts in microscopic field of view,a sub-pixel edge detection algorithm combining non-orthogonal quadratic B-spline wavelet transform algorithm and Zernike moment algorithm is proposed.Non-orthogonal quadratic B-spline wavelet transform algorithm is adopted to get the pixel edge of miniature parts,and the moment invariant of Zernike moment algorithm is used for refining the pixel edge to get sub-pixel edges.A real-time detection system based on t...
