Abstract

Abstract A sports analysis and testing system includes a plurality of high-speed digital video cameras, each aimed at a player from a different perspective to record their movements and those of a ball in play. In a baseball application, a programmed computer interfaced to the video cameras and various optional sensors includes application software to generate performance statistics as a function of the pitch, hit, and bat swing. If previously obtained batter performances data are available, the system may also be used to generate a database containing historical performance statistics, including real-time measurements of many characteristics, including pitched and batted ball speeds and trajectories, bat swing timing, speeds, and swing angles, location over the plate, and ball-bat contact location.

Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 165 words
A baseball bat performance and testing system, comprising: a pitching machine operative to pitch a ball to a batter; a plurality of high-speed digital video cameras, each operative to record the pitch and hit of the ball by the batter from a different perspective, including at least one rear-view video camera positioned generally behind the batter having a field of view in substantial alignment with the ball in trajectory from the pitching machine, and at least one side-view video camera having a field-of-view positioned to observe the pitch and hit of the ball from a side-view perspective; a computer interfaced to the video cameras, the computer including means for synchronizing images taken by the rear-view camera with those taken by the side-view camera to assist in determining the location of the ball as a function of time in three dimensions; and an application software program resident on the computer to generate the baseball bat performance statistics as a function of pitch, hit, and bat swing.
Claim 2
Dependent Claim 165 words
A baseball bat performance and testing system, comprising: a pitching machine operative to pitch a ball to a batter; a plurality of high-speed digital video cameras, each operative to record the pitch and hit of the ball by the batter from a different perspective, including at least one rear-view video camera positioned generally behind the batter having a field of view in substantial alignment with the ball in trajectory from the pitching machine, and at least one side-view video camera having a field-of-view positioned to observe the pitch and hit of the ball from a side-view perspective; a computer interfaced to the video cameras, the computer including means for synchronizing images taken by the rear-view camera with those taken by the side-view camera to assist in determining the location of the ball as a function of time in three dimensions; and an application software program resident on the computer to generate the baseball bat performance statistics as a function of pitch, hit, and bat swing.
Claim 3
Dependent Claim 32 words
The baseball bat performance and testing system of claim 1, further including a vibration sensor mounted on the bat and interfaced to the computer, enabling the performance statistics to include bat vibration.
Claim 4
Dependent Claim 38 words
The baseball bat performance and testing system of claim 2, wherein the bat includes a sweet spot, and wherein the vibration sensor and computer are operative to determine the hit of the ball relative to the sweet spot.
Claim 5
Dependent Claim 24 words
The batter analysis and testing system of claim 2, wherein the interface between the vibration sensor and the computer includes a wireless communication link.
Claim 6
Dependent Claim 22 words
The batter analysis and testing system of claim 1, further including software to isolate the movement of the ball from the background.
Claim 7
Dependent Claim 40 words
The batter analysis and testing system of claim 1, the computer further including a memory for storing previously obtained performance statistics with respect to a particular batter, enabling the system to generate a database of history performance for that batter.
Claim 8
Dependent Claim 34 words
The baseball bat performance and testing system of claim 1, further including one or more markers enabling the computer interface to the video cameras to isolate each point to which a marker is affixed.
Claim 9
Dependent Claim 35 words
The baseball bat performance and testing system of claim 1, further including a pointing device enabling an operator to identify points of the ball or batter to assist in the measurement of the movement thereof.
Claim 10
Dependent Claim 21 words
The baseball bat performance and testing system of claim 1, further including a video display showing the batter hitting the ball.
Claim 11
Independent Claim 150 words
A method of analyzing the performance of a baseball bat, comprising the steps of: providing a programmed computer having a display and a memory for storing performance statistics; pitching a ball to the batter using a pitching machine; providing a first high-speed digital video camera positioned generally behind the batter to image the ball in trajectory from the pitching machine and the batted ball according to a first perspective; providing a second high-speed digital video camera to image the pitched ball and batted ball from a side-view; synchronizing the images from the first and second video cameras so as to track the pitch and hit in three-dimensional space; developing a database of batter performance statistics based upon the tracking of the pitch and hit of the ball; and displaying a portion of the database in response to an operator request, including a visual representation of the batter during a swing.
Claim 12
Independent Claim 150 words
A method of analyzing the performance of a baseball bat, comprising the steps of: providing a programmed computer having a display and a memory for storing performance statistics; pitching a ball to the batter using a pitching machine; providing a first high-speed digital video camera positioned generally behind the batter to image the ball in trajectory from the pitching machine and the batted ball according to a first perspective; providing a second high-speed digital video camera to image the pitched ball and batted ball from a side-view; synchronizing the images from the first and second video cameras so as to track the pitch and hit in three-dimensional space; developing a database of batter performance statistics based upon the tracking of the pitch and hit of the ball; and displaying a portion of the database in response to an operator request, including a visual representation of the batter during a swing.
Claim 13
Dependent Claim 33 words
The method of claim 10, further including the step of receiving historical batter performance statistics, and wherein the step of developing a database of batter performance statistics includes the historical batter performance statistics.
