Teaching tool for the golfer - vision used to perfect swing

Recreational golfers can now perfect their swing on the practice tee through a teaching tool developed using advanced vision technology. R&D Vision, an R&D company based in the outskirts of Paris, France and specialising in advanced imaging solutions, has developed for their client V2S the system 'Swing & See', an innovative tutorial tool for the golf practice tee.

The system consists of an interactive terminal equipped with a colour touch-screen display which houses the control unit and image processing combined with two Pike digital cameras from Allied Vision Technologies (AVT).

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 in order to record the action from the front and the side. Thanks to the high frame rate (200fps) and a very short shutter time (<500µs), 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 viewing angles.

'For that project, a high frame rate and a short shutter time were key to ensure precise, high-quality recordings which are crucial for the ongoing analysis,' said Arnaud Susset, CEO of R&D Vision. AVT's Pike F-032B and its high-speed IEEE 1394b interface were the best choice for this application.

Swing & See is currently in the marketing phase and a dozen systems have already been successfully deployed on French golf courses.
