This paper provides a general framework for optimizing the trajectory of an observer by means of bearings-only tracking (BOT) in the case where the source is maneuvering. The basic problem of target motion analysis (TMA) is to estimate the trajectory

International audience; We investigate the problem of determining the trajectory that an observer should follow to be able to accurately track a target in a bearings-only measurements context. We assume that the target’s motion is uniform and that

Video extraction and tracking of moving targets with a camera

Autor: Dann Laneuville, Adrien Negre

Publikováno v: 2017 IEEE Aerospace Conference.

Cameras are nowadays widely used in maritime surveillance applications to detect small non-cooperative boats. This paper presents a simple and efficient video extractor based upon the background subtraction approach to obtain a binary mask of the mov

4D Cartesian state estimation of sea surface targets with a single camera

Autor: Adrien Negre, Pauline Dufour, Dann Laneuville

Publikováno v: 2016 IEEE Aerospace Conference.

Cameras are nowadays widely used in maritime surveillance applications to detect small non-cooperative boats. This paper presents a simple and efficient way to model the output of an image processing system obtained on different sea surface targets a
