The passing of a club head to hit a ball is detected by a sensor. A detection signal is sent from the sensor to a trigger section of a control unit. In response to the detection signal, shutter signals are sent from the trigger section to first and second cameras at a proper timing, while providing an appropriate time lag between the shutter signals, so as to photograph an image of the hit golf ball through the first and second cameras. The first and second cameras are disposed facing horizontally, apart from each other, and away from the set position of the ball at a predetermined distance. This method enables the motion of the golf ball to be measured even outdoors and through use of a relatively inexpensive apparatus.Field of SearchProjectile addressing surface and target, or distance marker (e.g., course, putting green with cup, driving range, miniature golf course, etc.)Electrical sensor or electrical indicator responsive to swingable implement or projectile Sensor is projectile responsive (e.g., free-flight detection means, etc.) Projectile in receiver indicator Target impact responsive Including sensor responsive to projectile on addressing surface or in flight (e.g., tee-target time detection, etc.) Pictorial flight path image display Moving projectile responsive sensor or indicator Electrical | |
