摘要
A system for measuring the distance traveled by bodies in flight during sports events, the bodies executing trajectories having a common predetermined take-off area, and a variable landing point within a landing surface. The system includes a fixed image acquisition device positioned at a predetermined distance from the take-off area for acquiring the image of the landing surface, a recorder for recording the landing surface image at least from the moment of initiation of the flight to completion of the flight, an identifying device for identifying a landing point of the body within the landing surface, and a calculating device for calculating the distance of the landing point from the take-off area.
