3-8 Free-viewpoint Video Generation for Sports Scene Based on Dynamic Camera Calibration and Object Tracking

Abstract

In this paper, we propose a dynamic camera calibration and object tracking method for sport videos captured with a moving pan-tilt-zoom camera. Our proposed method estimates camera parameters by identifying corresponding feature points between video frames. Furthermore, the method conducts object tracking based on the position of each object calculated with the estimated camera parameters for every frame. Experimental results show the effectiveness of the proposed method.
