Abstract:
1. A non-transitory computer readable medium having computer executable instructions thereon for performing analysis of a pitched ball from a pitcher to a batter that are separated by a first distance, the computer executable instructions including instructions configured to operate one or more computer devices to perform the steps of: processing a measured first speed of the ball thrown over the first distance; processing a destination of the ball within a region proximate to the batter; and determining a second speed of the ball calculated from the first speed of the ball and the destination; wherein the processing a destination involves dividing the region into an array of subregions, and selecting the subregion intersected by the ball; and wherein the determining further comprises: calculating a time unit over which the ball travels a second distance; determining a time period during which the ball travels the first distance; calculating a modified pitch speed according to a ratio of the first distance to the time period incremented by the time unit; calculating a velocity adjustment unit according to a difference between the first speed and the modified pitch speed; assigning multiplier values to the subregions, the multiplier values calculated so as to facilitate a contact of the ball by the batter; selecting from the multiplier values the multiplier value assigned to the selected subregion; and calculating the second speed according to the sum of the first speed and the product of the selected multiplier value and the velocity adjustment unit.
