Football rebound rate photoelectric detection method based on horizontal displacement difference compensation

摘要: The invention discloses a football rebound rate photoelectric detection method based on horizontal displacement difference compensation. comprises the steps of measuring time data and calculating rate, is characterized by comprising following steps: (1) about that three points lower surface upper trigger sensors in sequence first falling process ground-touch football, (2) delta x center according to point measured wherein when smaller than 0.03m, qualified; (3) height rebounding for step (1), performing compensation virtue calculated calculation, further rate. As whether qualified judged difference, wrong measurement result can be eliminated, meanwhile, as breeze influence within certain range effectively overcome, absolute error less or equal 0.1%, equipment precision improved.
