Camera Technology
Pro and amateur golfers alike are always on the lookout for ways to improve their golf swing. From purchasing new, custom-made clubs to taking all environmental variables into consideration, golfers also turn to golf swing analysis to improve their scores on the greens.
In order to improve a golf swing, a golfer needs to know where he might be going wrong, whether it’s in his grip or his follow through. Using the latest in digital camera technology that connects to a computer and uses machine vision applications, cameras that help analyze golf swings can go a long way in helping a golfer improve.
High-speed video recording with a wide-angle zoom lens and a standard tripod are the basics of the technology needed. A variable zoom wide-angle lens allows for the capturing of an image of a standing six-foot tall adult from seven feet away. There are several software programs on the market for video analysis and many of them incorporate easily into equipment a golfer may already own, or he may need to upgrade his camera speed or video recorder to one that can capture high-speed images. Incorporation of new lenses onto the camera to capture wide-angle views may also be necessary. To fully utilize this technology, the camera/video would need to have a shutter speed of 1/10,000, as this would eliminate any blurring from the image. A high sensitivity CCD sensor housed within the high-speed cameras can also capture freeze motion images for later review.
When recording the golf swing, it’s best to capture the images at 120 frames per second. To capture your golf swing for full analysis, the golfer would need to position the camera opposite a point between the feet and the ball. To get a true reading of the club line at the top of the golfer’s swing, two cameras are needed; one between the ball and the feet which would measure swing plane and a second camera opposite the club to capture the top of the swing and the club line.
Universe Optics carries a complete line of manual photographic lenses with various focal lengths, which are an economical alternative for large format CCD imaging applications and line scan cameras and can be used in golf swing technology applications.
