A camera-based scoring system for evaluating performance accuracy during a golf putting task
MetadataShow full item record
Golf putting accuracy is often evaluated by measuring the distance that the ball finishes from the hole. However, accuracy is a function of line and length, and distance-from-hole measures confound these two factors. A scoring system for evaluating putting accuracy is described that enables the efficient measurement of errors in line and length. A camera placed above the hole takes digital photographs of the final position of the ball. A custom-developed program written in the National Instruments LabVIEW graphical programming language derives a variety of accuracy measures from these photographs, including distance from the hole, angle of error, distance short or long from the hole, and distance left or right from the hole. Evaluation of the system indicated that the measures were as accurate as manual measurements and were reliable when rescored on separate occasions. The camera-based scoring system presents a number of advantages in the evaluation of putting accuracy and may be extended to examine performance in other sports.
