ABSTRACT:
A ball motion measuring apparatus comprises a tee3for mounting a golf ball1thereon, a first camera5, a second camera7, a pair of first stroboscopes9, a pair of second stroboscopes11, a pair of optical sensors13, a CPU15to be a calculating section, and a monitor17to be a display section. The first camera5and the second camera7are CCD cameras having a shutter function. Photographing is carried out by means of the first camera5after a predetermined time passes since the golf ball1is hit, and the photographing is carried out by means of the second camera7after a predetermined time further passes. A magnified image is formed by original image data thus obtained and a read value obtained by pointing the magnified image is subjected to distortion correction or oblique correction so that correction data are obtained. Based on the correction data, a flight speed, a spin rate or a launch angle of the golf ball1is calculated.
