Piscaer, P. (author), Henrion, S. (author), Binnerts, B. (author), Van Antwerpen, M. (author), Fermoselle, L. (author), Van Der Hurk, S. (author), Ter Haar, F. (author)This paper presents a systematic cost-effective approach for underwater 3D photogrammetric reconstruction. Underwater 3D reconstruction is a complicated task due to limiting and varying environmental conditions such as: low light conditions, sea snow, water currents and temperature. Quay wall inspection suffers from other possible complications...conference paper 2022

Illing, B. (author), Westhoven, M. (author), Gaspers, B. (author), Smets, N. (author), Bruggemann, B. (author), Mathew, T. (author)Despite advances regarding autonomous functionality for robots, teleoperation remains a means for performing delicate tasks in safety critical contexts like explosive ordnance disposal (EOD) and ambiguous environments. Immersive stereoscopic displays have been proposed and developed in this regard, but bring about their own specific problems, e...conference paper 2020

van de Wouw, D.W.J.M. (author), ter Haar, F.B. (author), Dubbelman, G. (author), de With, P.H.N. (author)We propose a real-time change detection system to be used as a vehicle-mounted early-warning system for indicators of improvised explosive devices. Within the context of military route clearance, the system automatically detects suspicious changes in the environment with respect to a previous patrol. For this purpose, historical images of the...article 2019

van der Mark, W. (author), van den Heuvel, J.C. (author), Groen, F.C.A. (author), TNO Defensie en Veiligheid (author)Autonomous robot vehicles that operate in offroad terrain should avoid obstacle hazards. In this paper we present a stereo vision based method that is able to cluster reconstructed terrain points into obstacles by evaluating their relative angles and distances. In our approach, constraints are enforced on these geometric properties by a set of...conference paper 2007

van der Mark, W. (author), Fontijne, D. (author), Dorst, L. (author), Groen, F.C.A. (author), TNO Fysisch en Elektronisch Laboratorium (author)A method for estimating ego-motion with vehicle mounted stereo cameras is presented. This approach is based on finding corresponding features in stereo images and tracking them between succeeding stereo frames. Our approach estimates stereo ego-motion with geometric algebra techniques. Starting with a simple linear estimate of the ego-motion,...conference paper 2003
