Any golfer, from weekend hacker to top-ranked professional, will confirm that mastering the perfect swing is a matter of practice and patient training. Professionals have been using video recordings for a long time to analyze their swing in detail and then improve it. With the system "Swing & See" developed by R&D Vision (Saint Maur des FossÚs, France), amateurs now can use this technology, too, and benefit from a powerful analysis tool on their local golf courses. This system relies on sophisticated cameras to capture and precisely document each phase of the swing movement. R&D selected the Pike series from Allied Vision Technologies (Stadtroda, Germany).

A SELF-SERVICE TOOL

It has, of course, always been possible for any golfer to have himself or herself filmed by a friend with a camcorder to analyze their mistakes. Although this method may provide some help, it offers only very limited analysis capabilities: the image quality depends on the quality of the camera used and the skills of the person operating it. Besides, the recordings cannot be viewed properly on site without an appropriate display. They may include movement artifacts and show the action only from one view angle.

R&D Vision, a research & development company specialized in advanced imaging solutions based about seven miles from Paris, developed the "Swing & See" system, an innovative tutorial tool for the golf practice tee, for its client, V2S. This system offers recreational golfers the possibility to improve their swing using advanced professional vision technologies.

The system consists of an interactive terminal equipped with a color touch-screen display that houses the control unit and image processing combined with two AVT Pike digital cameras. The whole set is permanently installed on the practice tee and is weather-proof for outdoor installation. The user interface is easy and intuitive.

The move of the swinging player is captured by the two cameras simultaneously at 200 images per second. The cameras are positioned with a 90░ angle to each other to record the action simultaneously from the front and the side. Thanks to the high frame rate (200 fps) and a very short shutter time (less than 500 Ás), the cameras provide very sharp images of every single step of the movement. The start of recording is automatically and simultaneously triggered by image processing software able to identify the position of the ball. Thus, the whole swing process is precisely captured from both view angles.
