Abstract
A system for measuring pitting corrosion in metal using a digital camera having a lens and an output unit for identifying the color of a metal coupon on a gray scale and providing an output in the midrange of the scale when non corroded and different output after exposure to a corrosive environment. A computer is connected to the output of the camera to display the photographs to permit observation of the gray scale output based upon a minimum and maximum threshold inputs which are adjustable based on an observation of pitting. The points of interest on the coupon representing observed pitting are recorded and summed to calculate an estimated corrosion area corresponding to pitting the said coupon as a percentage of the total coupon area.
