PURPOSE: A golf practice system is provided to help a user to perform an effective practice by measuring a specific distance of a golf ball on the basis of a flying distance and hitting time. CONSTITUTION: The golf practice system comprises a first sensor(110) for detecting a hitting time point of a golf ball at a certain hitting position; a second sensor(120) spaced apart from the first sensor for detecting the contact of the golf ball; a timer coupled to the first and second sensors for providing hitting and contact time information; an initial image data memory part for saving first image data before the golf ball reaches the second sensor; a camera(130) for providing image data at the front of the second sensor; an image capture part for selecting certain image data of contact moment of golf ball with the second sensor on the basis of signals applied from the second sensor; a contact position detecting part for producing contact position information by comparing the first image data with the second image data; a result output device(150); and a golf practice control device(140) by outputting and controlling practice result information calculating a specific distance of the golf ball.
