| Summary: | 1. Field of the Invention
A method of training a system to identify inspection sites on a circuit board is described. The method uses a priori information, which includes a region of interest, approximate sizes and approximate spacings of a plurality of nominal pad locations, and a pad count or an aperture count. A region is created which is associated with each one of the nominal pad locations within an image of a printed circuit board. A search tool is run to find pad candidates within each one of the regions. The pad candidates are filtered. The best pad candidates are selected from among each of the found pad candidates. The best pad candidates are averaged to provide an average, and are modified based on the average. |
