This paper presents a self-calibration technique for a camera mounted on an underwater vehicle designed to perform the 3D reconstruction of underwater scenes. Our aim is to identify the intrinsic parameters of the camera with methods that are adapted to the operational constraints on Ifremer's underwater vehicles. The optical system is composed by a single(More)
— This paper addresses the issue of estimating underwater vehicle trajectories using Gyro-Doppler (body-xed velocities) and acoustic signals (earth-xed positions). The approach consists of diffusion-based observers processing a whole trajectory segment at a time, allowing to consider important practical problems such as different information update rates,(More)
