Photoelectric detection algorithm for football bounce rate measurement based on horizontal displacement compensation

A photoelectric detection algorithm for measuring football bounce rate based on horizontal displacement compensation has been developed. This algorithm is able to correct the horizontal movement of a free falling object affected by breeze or wind. The horizontal deviation between the football center and the gravity line during the first free fall was calculated, according to which test passes were determined. If a test satisfies the passing standard, then the first rebound height was compensated by horizontal displacement. A previously developed football bounce rate detector was used for experiments, and the results showed that the football bounce rate photoelectric detection algorithm based on horizontal displacement compensation can effectively overcome the impact of a range of breeze or wind, and the absolute detection errors were within the range of 1%.
