Abstract
An exemplary embodiment of the invention is a method and system for determining a radius of curvature of a two-dimensional curved feature. The system includes an image acquisition device for obtaining images of said curved feature. A processor is coupled to the image acquisition device for receiving the images and converting the images to n sets of coordinates corresponding to points on the perimeter of the curved feature. The processor chooses at least three sets of said coordinates to define at least one group and fits each set of said coordinates from each group to an equation for a circle and determines a radius of curvature by solving each equation simultaneously. A storage device is coupled to the processor for storing processor data. An output device is coupled to the processor for outputting processor data.
