摘要：
A method and apparatus are provided for the determination of a surface area of a fastener, such as a threaded fastener. Specifically, an image of the fastener is acquired, and the image is separated into at least two regions, for instance three regions, and the surface area of each region is determined. The surface areas determined for each region are summed to determine the surface area of the fastener.
