ABSTRACT:
A digital image of the connector pins and their mounting surface background is produced from a direction parallel to the pins by a ccd camera with a telocentric lens and a fiber optic ring light. The image is filtered, binarized and blob analyzed by computer to find rows of blobs that represent rows of pins. The attributes and spacing of the pin blobs are then compared against predetermined criteria to determine pin failures.
