Abstract: In PCB SMT assembly automatic machine vision inspection,image mosaic is necessary for getting an entire PCB image.Because of inhomogeneous illumination in this engineering image capture,conventional mosaic methods didn’t word well.High frequency coefficients of wavelet decomposition can reflect the contour of the image and that of illumination variety is relative small,so image mosaic based on wavelet decomposition can be robust for PCBA inspection.Using projection of wavelet decomposition coeff...
