<p>A golf ball is illuminated with diffused back lighting. CCD images of the golf ball are taken while the golf ball is being illuminated with the diffused back lighting. The edge or circumference of the golf ball is captured and sharply defined in the CCD images. The uniformity of the circumference may be determined by evaluating the radius of the object's circumference in an image, where an image is generated for n points around the circumference of the object, such as every 20 ° or 30°. By rotating the game ball, preferable with a battery operated stepper motor, the surface of the golf ball can be mapped.</p> |
