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:
- positioning a golf ball for non-rotation in a x-ray measurement region of an imaging machine;
- taking at least one X, Z image of the golf ball using a first x-ray source, a first camera and a first image intensifier;
- taking at least one Y, Z image of the golf ball using a second x-ray source, a second camera and a second image intensifier;
- taking at least one X, Y image of the golf ball using a third x-ray source, a third camera and a third image intensifier;
- determining a diameter or ellipse dimensions of an inner edge and an outer edge of a layer of the multiple layer golf ball utilizing an edge detection algorithm;
- calculating X,Z coordinates of a best fit diameter or ellipse of the inner and outer edges of the multiple layer golf ball;
- calculating Y, Z coordinates of a best fit diameter or ellipse of the inner edge and outer edge layer of the multiple layer golf ball;
- calculating X, Y coordinates of the a best fit diameter or ellipse of the inner edge and outer edge layer of the multiple layer golf ball;
- combining the at least one X, Z image, the at least one Y, Z image and the at least one X, Y image to calculate a 3D distance;
- and
- comparing Y, Z center coordinates, X, Z center coordinates and X, Y center coordinates of a specified layer to determine concentricity of an inner layer within any of the outer layers.
