2-6 Free-viewpoint Contents Synthesis based on Dynamic Camera Calibration of Moving Cameras

Abstract

In this paper, we propose a dynamic camera calibration and object extraction method for sport videos captured with a moving pan-tilt-zoom camera. Our proposed method estimates camera parameters by identifying reliable corresponding feature points between video frames, and also extracts objects' textures by projecting the feature line between field plane and stadium stand with estimated camera parameters. Experimental results show the effectiveness of the proposed method.
