摘要: The Hawk-Eye line-calling system in tennis uses a footprint of the ball to determine whether was or out. However, itself is not measured. It trajectory through air that Measurements are presented this paper, showing how high initial rate expansion and other technical difficulties can lead potential errors system. measured for vertical oblique impacts, compared with recent results at tournament where installed.
