Abstract
A system and a method related for evaluation of sport ball data. The method includes calibrating a first coordinate system of a first camera to a second coordinate system of a baseball field; capturing, with the first camera, one or more images including a first batter; determining biometric characteristics of the first batter based on the one or more images and the calibration of the first camera to the baseball field; mapping the biometric characteristics of the first batter to an upper positional limit and a lower positional limit of a first strike zone for the first batter; and determining positional limits of the first strike zone in the second coordinate system.
Claims31
A method, comprising:
- calibrating a first coordinate system of a first camera to a second coordinate system of a baseball field;
- capturing, with the first camera, one or more images including a first batter;
- determining biometric characteristics of the first batter based on the one or more images and the calibration of the first camera to the baseball field;
- mapping the biometric characteristics of the first batter to an upper positional limit and a lower positional limit of a first strike zone for the first batter;
- and
- determining positional limits of the first strike zone in the second coordinate system.
A method, comprising:
- calibrating a first coordinate system of a camera to a second coordinate system of a baseball field;
- capturing, with the camera, one or more images including a first batter;
- determining pose data corresponding to a three-dimensional pose of the first batter based on the one or more images and the calibration of the camera to the baseball field;
- mapping the pose data of the first batter to at least one of an upper positional limit and a lower positional limit of a first strike zone for the first batter;
- and
- determining positional limits of the first strike zone in the second coordinate system based on the mapped at least one of the upper and lower positional limits of the first strike zone.
A system for monitoring a baseball game, comprising:
- a first sensor arrangement configured to capture one or more images including a first batter;
- and
- a processor configured to:
- calibrate a first coordinate system of the first sensor arrangement to a second coordinate system of a baseball field;
- determine biometric characteristics of the first batter based on the one or more images and the calibration of the first sensor arrangement to the baseball field;
- map the biometric characteristics of the first batter to one of an upper positional limit and a lower positional limit of a first strike zone for the first batter;
- and
- determine positional limits of the first strike zone in the second coordinate system.
A system, comprising:
- a first sensor arrangement configured to capture one or more images including a first batter;
- and
- a processor configured to:
- calibrate a first coordinate system of the first sensor arrangement to a second coordinate system of a baseball field;
- when the first batter is a current batter, determine pose data corresponding to a three-dimensional pose of the first batter based on the one or more images and the calibration of the first sensor arrangement to the baseball field;
- map the pose data of the first batter to at least one of an upper positional limit and a lower positional limit of a first strike zone for the first batter;
- and
- determine positional limits of the first strike zone in the second coordinate system based on the mapped at least one of the upper and lower positional limits of the first strike zone.
