BASEBALL PITCH QUALITY DETERMINATION METHOD AND APPARATUS

摘要

The disclosure provides for systems and methods for determining a pitch rating for a pitch in baseball. The pitch rating can be configured to be indicative of a quality of breaking and non-breaking pitches. The disclosure provides for a detection system that detects the position of the ball. The pitch rating can then be calculated by extracting flight parameters from the detection data and multiplying appropriate flight path parameters by pitch rating coefficients. The pitch rating coefficients can be tailored such that the pitch rating calculation provides a value that is correlated to a subjective opinion on pitch quality provided by an expert. The pitch rating can then be displayed in real time to provide feedback or information about a quality of the pitch.

主权项

1. A system for determining a pitch rating for a pitch in baseball, the pitch rating indicative of a quality of the pitch, the system comprising:
a detection system configured to detect a ball in flight and to determine a position and a speed of the ball; and a pitch quantification system comprising:
one or more hardware processors;a flight path module configured to receive from the detection system the position of the ball and to determine information representative of a flight path of the ball;a pitch parameter module configured to receive the information representative of the flight path of the ball from the flight path module and to generate pitch parameters corresponding to properties of the path of the ball the generated pitch parameters including a rise component, a breakpoint component, a vertical break component, a horizontal break component, and a final location component; anda pitch rating module configured to:
determine a trajectory metric as a linear combination of the generated pitch parameters;determine a speed adjustment parameter by taking a difference between the speed of the ball and a speed threshold;calculate the pitch rating indicative of the quality of the pitch, the pitch rating equal to a mathematical combination of the trajectory metric and the speed adjustment parameter.
