IMM-based tracking and latency control with off-the-shelf IP PTZ camera
Résumé
Networked Pan-Tilt-Zoom cameras (PTZ) seem to replace static ones in videosurveillance areas as they are easier to deploy, with a larger field of view and can take high resolution pictures of targets thanks to their zoom. However, current algorithms combining tracking and camera control do not take into account order executing latency and motion delays caused by off-the-shelf cameras. In this paper, we suggest a new motion control strategy that manages inherent delays by an Interacting Multiple Models prediction of the target motion and an online evaluation of this prediction.
