Abstract
Method and apparatus are disclosed for analyzing an image produced by a camera focused on the leads of a component that have been inserted into a printed circuit board by a component insertion machine. The method and apparatus include the construction of arrays of information pertaining to individual leads that should be present in the image produced by the camera. Individual strings of pixel information in the form of binary encoded bits within each array are analyzed for the presence of a pattern of bits that would indicate a lead. The method and apparatus are operative with respect to a pixel resolution that may only produce a single properly encoded bit per width of inserted lead.
