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.
Claims20
A method for determining concentricity of a multiple layer golf ball, the method comprising:
- taking a first plurality of images of the full cross-sectional view of the golf ball using an x-ray source and a digital detector;
- averaging the first plurality of images into a single first image of the full cross-sectional view of the golf ball;
- calculating Y,Z center coordinates of a best fit diameter or ellipse of an inner edge layer and an outer edge layer of a specific layer of the multiple layer golf ball using the single first image of the full cross-sectional view of the golf ball;
- rotating the golf ball to a new orientation within an imaging machine 90 degrees about a Z-Axis;
- taking a second plurality of images of the full cross-sectional view of the golf ball in the new orientation using the x-ray source and the digital detector;
- averaging the second plurality of images into a second single image of the full cross-sectional view of the golf ball;
- calculating X,Z center coordinates of a best fit diameter or ellipse of the inner edge layer and outer edge layer of the specific layer of the multiple layer golf ball;
- and
- comparing the X,Z and Y,Z center coordinates of the specific layer to determine the concentricity of the inner layer within any of the outer layers.
