Abstract

In this study, we proposed a method for detecting a player’s movement trajectory from video images to evaluate the defensive range of an outfielder in baseball, quantitatively. Using this method, we succeeded in accurately estimating and visualizing the movement trajectory of a player by identifying only specific players and estimating the homography of changes in the angle of the view by matching the feature points using SIFT.
