A Robust Free-viewpoint System Video for Sport Scenes
نویسندگان
چکیده
This contribution describes robust methods to provide a freeviewpoint video visualisation of sport scenes using a multicamera set-up. This allows generation of novel views of actions from any angle and is of interest for visualisation in TV productions. The system utilises 3D reconstruction techniques previously developed for studio use. This paper discusses some experiences found while applying these techniques for an uncontrolled ourdoor environment and addresses robustness issues. This includes segmentation, camera calibration and 3D reconstruction. A number of different 3D representations, including billboards, visual hulls and viewdependent geometry are evaluated for the purpose.

A free-viewpoint video system for visualisation of sport scenes
This contribution introduces a new approach of using multi-camera images of an event to provide a free-viewpoint video visualisation of sport scenes. This allows a virtual camera to be moved freely around and to view the action from any angle. The system is based on 3D reconstruction techniques previously developed for studio use. A number of different 3D representations, including billboards, ...
متن کاملFree-Viewpoint Video for TV Sport Production
Free-viewpoint video in sports TV production presents a challenging problem involving the conflicting requirements of broadcast picture quality with video-rate generation of novel views, together with practical problems in developing robust systems for cost effective deployment at live events. To date most multiple view video systems have been developed for studio applications with a fixed capt...
متن کاملA Flexible and Versatile Studio for SynchronizedMulti-View Video Recording
In recent years, the convergence of computer vision and computer graphics has put forth new research areas that work on scene reconstruction from and analysis of multi-view video footage. In free-viewpoint video, for example, new views of a scene are generated from an arbitrary viewpoint in real-time using a set of multi-view video streams as inputs. The analysis of real-world scenes from multi...
متن کاملData Format and Coding for Free Viewpoint Video
In this paper we will discuss data representation formats and coding aspects of a new 3D functionality called Free Viewpoint Video (FVV). Similar to Computer Graphics (CG) or VRML applications, FVV allows for navigating with a virtual camera in 3D scenes. However, in contrast to graphical scenes in CG and VRML, FVV is based on natural scenes consisting of 3D video objects that provide a higher ...
متن کاملProjective Surface Refinement for Free-Viewpoint Video
This paper introduces a novel method of surface refinement for free-viewpoint video of dynamic scenes. Unlike previous approaches, the method presented here uses both visual hull and silhouette contours to constrain refinement of viewdependent depth maps from wide baseline views. A technique for extracting silhouette contours as rims in 3D from the view-dependent visual hull (VDVH) is presented...
