METHOD FOR MEASURING FLIGHT BEHAVIOR OF FLIGHT OBJECT

摘要

PROBLEM TO BE SOLVED: To provide a method for measuring the flight behavior of a flight object capable of performing the measurement of the flight behavior of the flight object performed indoors heretofore, for example, the measurement of the initial trajectory of a golf ball even in an outdoor environment receiving external light and avoiding the complication of a measuring system or an increast in the cost of an apparatus. SOLUTION: The flight object is exposed for a predetermined time and the flight locus of the flight object from the start of exposure to the completion thereof is photographed by a camera (step 106) and the first center-of-gravity position of the flight object at the time of start of exposure and the second center-of-gravity position thereof at the time of completion of exposure are detected from the contour of the flight object at the time of start of exposure in the flight locus within the photographed image and the contour of the flight object at the time of completion of exposure (step 119), and the detected first and second center-of-gravity positions and the exposure time at the time of photographing by the camera are at least used to calculate the flight parameter of the flight object (step 120).
