This paper proposes an automating method to determine a viewpoint for generating a 3D video of soccer games. Our proposed method aims to realize an empathic 3D video system that counts users' personal preference. Our system first classifies the soccer game into some soccer events by referring to 3D position of soccer players and a ball. For each event in soccer games, typical viewpoints, which are preferred by many numbers of users, have been estimated by a clustering method with interview survey. In a phase of presenting 3D video, the user inputs his/her individual taste of viewpoint by trial-using 3D video system in a few soccer events. Our system estimates a viewpoint to generate the user's favorite 3D video by choosing a typical viewpoint which is the nearest to user's input. With interpolating the selected typical viewpoints in soccer events by B-spline curve, this system generates a sequence of 3D video. We confirm the effectiveness of our proposed method in subjective evaluation experiments.
