A system and a method for measuring flight parameters of a spherical object are disclosed. A trigger signal-generating unit generates and outputs a first trigger signal upon detection of a spherical object, and generates and outputs a second trigger signal when a reference time interval which is set on the basis of the maximum flight speed and the maximum rotating speed of the spherical object has elapsed from the point in time when the first trigger signal was generated. A photographing unit photographs images in a first image acquiring region having a predetermined area in which the spherical object exists, in accordance with the first trigger signal and the second trigger signal. An image-acquiring unit provides the photographing unit with the first trigger signal and the second trigger signal inputted by the trigger signal generating unit, and converts a plurality of images inputted by the photographing unit in accordance with the first and second trigger signals into digital images, and stores the digital images. A parameter-measuring unit calculates flight parameters including the flight speed, flight angle, rotating speed, and rotational axis of the spherical object from the plurality of digital images. |
