RP14: Markerless Motion Capture Technologies For In-Game Player Performance Assessment Michael Eckstein
Coaches and trainers focus upon getting successful player motions continuously repeated. Until recently, the only method available to track and capture multiple view biomechanical data was to use a “marker” system based upon attaching reflective materials to a confining and bulky Spandex® body suit. Using high speed cameras with advanced optics and telephoto lenses, an integrated Markerless MoCap hardware/software technology platform can provide “live game” baseball player performance and skills assessment. Eckstein discusses the evolution from marker to markerless systems, how the technology is deployed within a baseball stadium, and examples of how user interface formats and analytics can be used by coaches, trainers, scouts, managers and players.
RP25: Analyzing Batter Performance Against Pitcher Clusters Vince Gennaro
Baseball data continues to grow exponentially. Over the last ten years, we have generated 95% of the game-level and pitch-level data that exists today. In other words, when the book Moneyball was written, we had less than 5% of today's baseball data. Gennaro leverages this data using community detection algorithms to create clusters of pitchers based on similarities multiple attributes, such as frequency of pitch types, velocity, release points, horizontal break, vertical break, pitch variety, pitch location, and handedness. This research could have implications for optimizing batter-pitcher relationships and matchups by identifying how hitter performance varies across these pitcher clusters.
