Patent ID: 8885042

Claim:
A system for measuring flight parameters of a spherical object, comprising: a trigger signal generation unit which generates and outputs a first trigger signal when a spherical object is detected, and generates and outputs a second trigger signal when a reference time interval set based on the maximum flight speed and the maximum rotation speed of the spherical object has passed since the generation time of the first trigger signal; a photographing unit which photographs a plurality of images of the spherical object with respect to a first image acquisition region having a certain area in accordance with a first trigger signal and a second trigger signal; an image acquisition unit which provides the first trigger signal and the second trigger signal, which are inputted from the trigger signal generation unit, to the photographing unit and converts and stores the plurality of the images inputted from the photographing unit into a digital image in response to the first trigger signal and the second trigger signal; and an information measuring unit which computes the flight parameter including a flight speed, a flight angle, a rotation speed and a rotation axis of a spherical object from the plurality of the digital images, wherein the reference time interval is determined with the maximum value of the reference time interval obtained by the formula A, wherein the formula A is, dT max =min( dT max1 , dT max2 ) where dT max is the maximum value of the reference time interval, and dT max1 is, dT max ⁢ ⁢ 1 = ( L v - D v ) V max where L v is the length of the vertical direction of the first image acquisition region, and D v is the distance that the spherical object flew in the vertical direction of the first image acquisition region until the spherical object is photographed in accordance with the first trigger signal since the coming-in boundary of the first image acquisition region, and V max is the value determined based on the maximum flight speed of the spherical object, and dT max2 is, dT max ⁢ ⁢ 2 = 30 N max where N max is the maximum rotation speed of the golf ball.
