Abstract
A method and system for determining concentricity of a multiple layer golf ball are disclosed herein. One or more images of a golf ball are generated using an X-ray source, a camera or a digital detector, and an image intensifier. An edge detection algorithm is preferably utilized. The method also includes calculating Y,Z center coordinates of the a best fit diameter or ellipse of the inner edge layer and outer edge layer of the multiple layer golf ball.

A method for determining concentricity of a multiple layer golf ball, the method comprising:
- determining an outer edge of a first layer of a golf ball from a plurality of X-ray images of the golf ball, the plurality of X-ray images comprising at least one X, Z image of a full cross-sectional view of the golf ball using a first image intensifier and at least one Y, Z image a full cross-sectional view of the golf ball using a second image intensifier;
- generating a best fit ellipse for the outer edge of the first layer based on a plurality of points of the outer edge;
- determining an inner edge of the first layer of a golf ball from the plurality of X-ray images of the golf ball;
- generating a best fit ellipse for the inner edge of the first layer based on a plurality of points of the inner edge;
- and
- determining a concentricity of the first layer of the golf ball.
