Today, we worked with the digital imaging analysis to determine if we can distinguish differences in ball mark volume using digital images. Ball marks were greated in the putting green at various air pressures. A ball mark was created at 30, 40 50, 60, and 70 psi of pressure. At 30 psi we got a small impression that was hardly noticable. At 50, 60, and 70 psi, we were able to get much larger ball marks, but the shape of the mark was interesting. At 50 and 60 psi the ball marks were more conical. I assume this result is from the ball bouncing out of the mark. The ball basically plugged in the ball mark at 70 psi.
Two balls were fired high into the air to create ball marks from the ball descending due to gravity. The two ball marks were captured with the digital camera to correlate those ball marks to the ones shot into the green at the various psi's listed. Based solely on visual camparisons, the ball mark at 40 psi appeared most similar to the ones created with the ball landing on the green from high arching golf balls.
Studies may need to be performed to measure ball marks using the ball lie system on actual golf shots landing on a green. We also need to determine or find the terminal velocity of a golf ball striking a green from a golf shot. The one aspect of a golf shot that was not incorporated at this point is backspin created when hitting a golf shot into the green.
Two digital images were captured with a red golf ball sitting in the ball mark created. The control (ball sitting on the green) and subsequent pressures were photographed corresponding to photographs bmvdia1-bmvdia12. Photographs bmvdia13-bmvdia16 were taken of the two golf balls launched high into the air to determine the size of those ball marks. The last four pictures need to be compared to the previous photographs to determine the optimum psi to fire golf balls at the green.
Pictures will be analyzed using software tomorrow to determine what differences occurred.
