Virtual camera synthesis for soccer game replays

International audienceIn this paper, we present a set of tools developed during the creation of a platform that allows the automatic generation of virtual views in a live soccer game production. Observing the scene through a multi-camera system, a 3D approximation of the players is computed and used for the synthesis of virtual views. The system is suitable both for static scenes, to create bullet time effects, and for video applications, where the virtual camera moves as the game plays

Soccer on Your Tabletop

We present a system that transforms a monocular video of a soccer game into a moving 3D reconstruction, in which the players and field can be rendered interactively with a 3D viewer or through an Augmented Reality device. At the heart of our paper is an approach to estimate the depth map of each player, using a CNN that is trained on 3D player data extracted from soccer video games. We compare with state of the art body pose and depth estimation techniques, and show results on both synthetic ground truth benchmarks, and real YouTube soccer footage.Comment: CVPR'18.

3D-TV Production from Conventional Cameras for Sports Broadcast

3DTV production of live sports events presents a challenging problem involving conflicting requirements of main- taining broadcast stereo picture quality with practical problems in developing robust systems for cost effective deployment. In this paper we propose an alternative approach to stereo production in sports events using the conventional monocular broadcast cameras for 3D reconstruction of the event and subsequent stereo rendering. This approach has the potential advantage over stereo camera rigs of recovering full scene depth, allowing inter-ocular distance and convergence to be adapted according to the requirements of the target display and enabling stereo coverage from both existing and ‘virtual’ camera positions without additional cameras. A prototype system is presented with results of sports TV production trials for rendering of stereo and free-viewpoint video sequences of soccer and rugby

American Professional Sport Facilities: Considerations for the Future

This work reveals American professional sport facilities impose staggering financial and spatial costs on the surrounding communities and suggests three areas future professional sport facility designers should consider before partaking in future renovations or new construction opportunities. The three areas include reducing the size, considering the environment, and embracing interaction and telecommunication technology. This work supports future American professional sport facilities are quite capable of reducing their size and costs while also maintaining or creating social and financial benefits for itself and the local community. For example, the professional sport facility can support more community-oriented activities through using the ‘innards’ of the stadium to justify public money. The professional sport facility will also need to respect the physical and biological environment and can through the use of renewable sources of energy (e.g. sun, water, wind). Finally, future professional sport facilities ought to embrace interaction and telecommunication technology to help improve the spectator experience.sports

iBall: Augmenting Basketball Videos with Gaze-moderated Embedded Visualizations

We present iBall, a basketball video-watching system that leverages gaze-moderated embedded visualizations to facilitate game understanding and engagement of casual fans. Video broadcasting and online video platforms make watching basketball games increasingly accessible. Yet, for new or casual fans, watching basketball videos is often confusing due to their limited basketball knowledge and the lack of accessible, on-demand information to resolve their confusion. To assist casual fans in watching basketball videos, we compared the game-watching behaviors of casual and die-hard fans in a formative study and developed iBall based on the fndings. iBall embeds visualizations into basketball videos using a computer vision pipeline, and automatically adapts the visualizations based on the game context and users' gaze, helping casual fans appreciate basketball games without being overwhelmed. We confrmed the usefulness, usability, and engagement of iBall in a study with 16 casual fans, and further collected feedback from 8 die-hard fans.Comment: ACM CHI2

Televisual sports videogames

Thesis (S.M.)--Massachusetts Institute of Technology, Dept. of Comparative Media Studies, 2013.Cataloged from PDF version of thesis.Includes bibliographical references (p. 109-115).Over the three decade long history of sports videogame development, design conventions have lead to the emergence of a new sports game genre: the televisual sports videogames. These games, which usually simulate major professional or college sports, look and sound like television, and they use televised sports as a reference point for players. This thesis takes a critical look at how these televisual sports videogames are situated in the broader sports media industrial complex of North America, while also considering how the televisual design of these games is meaningful for fans of sports. Specifically, the text looks at how sports videogames reflect or reinforce dominant ideologies of hegemonic sports culture. Building on critical theories in sports studies, and through critical close readings of videogame texts, this thesis explores the relationship between sports television production, and sports videogames, with a focus on features that are found in both. Features such as introductory sequences, audio commentary, in-game advertising, news tickers, and instant replay are all commonly found in both sports television and sports videogames.by Abraham D.
