SkyTrak golf is developed by the American company SkyGolf. It uses a combination of a high-speed camera and infrared technology to test the effect of simulating the effect of hitting the ball. It can be connected to a mobile phone or computer, by detecting the moment of hitting the ball and a certain distance after the ball takes off and recording the take-off angle, direction, speed, and backspin of the ball, it can calculate the flight path of the ball, and obtain the ball trajectory and distance. Use indoors as well as outdoors, and can be used to simulate 18-hole games.
