The method includes using centrifugal force to place the fastener in a predetermined location. Two or more sets of image data of the fastener are generated from two or more corresponding different angles. Fastener pass/fail data is generated using a dimensional requirement associated with each set of image data.

  • Publication number: 20050047644
    Abstract: An inspection system is provided. The system includes a rotating prism having a first end and a second end. The first end receives a first image area, such as a circular view, and rotates about a center point so as to cover a field of view area that is larger than the first image area, such as a larger circle that is defined by the smaller circle of view as it rotates around the center point. The second end remains centered on the center point and provides a viewing area that does not change in dimension. An image data system at the second end of the rotating prism generates image data as the prism rotates so as to generate two or more sets of image data that are contained within the field of view area.
