BAQUEIRO VICTORIN, Guillermo  e  BERNARD HAYET, Jean. Robust Extrinsic Camera Calibration from Trajectories in Human-Populated Environments. Comp. y Sist. [online]. 2012, vol.16, n.1, pp.71-83. ISSN 2007-9737.

This paper proposes a novel robust approach to perform inter-camera and ground-camera calibration in the context of visual monitoring of human-populated areas. By supposing that the monitored agents evolve on a single plane and that the cameras intrinsic parameters are known, we use the image trajectories of moving objects as tracked by standard trackers in a RANSAC paradigm to estimate the extrinsic parameters of the different cameras. We illustrate the performance of our algorithm on several challenging experimental setups and compare it to existing approaches.
