PCB Image Registration Method Based on Mark Hole Feature Extraction

Abstract:

In the processing of PCB (Printed Circuit Board) defect inspection with reference comparison method, the very critical aspect is to make the image to be inspected and the reference standard PCB image accurate registration . Image registration has many ways, according to the characteristics of PCB, a new image registration method based on Mark hole center feature extraction was presented, also this method is carried out relevant experimental verification.
