Abstract

We propose a new method for estimating 3-D trajectories of a tennis ball from multiple video sequences and parameterizing the 3-D trajectories. We extract candidate positions of a ball by a frame difference technique and reconstruct 3-D positions of them by two-view reconstruction for every image pairs. By analyzing a distribution of the reconstructed 3-D points, we find a cluster among them and decide its cluster center as the 3-D ball position. Moreover, we fit a plane to the estimated 3-D trajectory and express them as a 2-D point data. We parameterize the 2-D data by fitting two parabolas to them. By simulation and real experiments, we demonstrate the efficiency of our method.
