Abstract
An apparatus and method to measure, monitor control the coating of objects in a processing line including a camera to receive an image of the profile of the object before being coated, a second camera to receive an image of the profile of the object after being coated, and a means and method to compare the two images to determine the increase in volume of the object due to the coating. The comparing means is a microcomputer which calculates the increase in volume based on the two images, the speed of the object travelling along the processing line, and a form factor. The microprocessor compares the increase in volume of one object to the increase in volume of a second object to monitor and ensure a consistent coating thickness.
