4th Lincs Scientific Highlight - LINCS Annual Workshop with its Scientific Committee

“Inferring object trajectories in a multi-camera environment”, by Marc-Oliver Buob (NBL).
This talk explains how to rebuild the trajectories of mobile objects of interest moving on a flat scene and observed by multiple cameras with overlapping fields of view. More specifically, we aim to find the trajectories of hockey players evolving on the Nokia Arena rink (Tampere, Finland). Using a YOLO-like detector, one can obtain approximate world coordinates of some of the players from each frame produced by each camera. The goal of this work is to rebuild the trajectories of each player given these streams of coordinates. These trajectories can be used to render the players within a 3D model of the arena, for example one that is generated by a NeRF (Neural Radiance Field). After covering the difficulties inherent to our problem, we will explain all the steps and the related optimization models used to transform camera feeds to player trajectories. This is a Joint work by Marc-Olivier Buob, Pierre Escamilla,, Jeongran Lee.
