In this paper, we suggest that method to estimate homography matrix automatically from a image that is important in the synthesis of free viewpoint video in an effort to estimate dynamic moving camera parameters used in broadcasting in soccer scene.
To estimate homography matrix, which need to connect image points to the known court model points of a world coordinate.
Traditionally, because it was to guess the corresponding intersection by limiting the position and orientation of camera's point of view, the use of images taken from various locations was difficult.
Therefore, by the direction of the court to grant the line components that extend from that point at the intersection, the intersection of the court and make a matching model to estimate the support from the component placement and direction of the intersection.
By comparing the placement of the intersection from the vertical and horizontal at the time of matching, will be robust in the direction of shooting, to get the plane projection matrix in far fewer restrictions.
This paper investigates an efficiency of propose method, it is tested by using actual soccer scene images.
