Visual SLAM for underwater vehicles using video velocity log and natural landmarks

A visual SLAM system has been implemented and optimised for real-time deployment on an AUV equipped with calibrated stereo cameras. The system incorporates a novel approach to landmark description in which landmarks are local sub maps that consist of a cloud of 3D points and their associated SIFT/SURF descriptors. Landmarks are also sparsely distributed which simplifies and accelerates data association and map updates. In addition to landmark-based localisation the system utilises visual odometry to estimate the pose of the vehicle in 6 degrees of freedom by identifying temporal matches between consecutive local sub maps and computing the motion. Both the extended Kalman filter and unscented Kalman filter have been considered for filtering the observations. The output of the filter is also smoothed using the Rauch-Tung-Striebel (RTS) method to obtain a better alignment of the sequence of local sub maps and to deliver a large-scale 3D acquisition of the surveyed area. Synthetic experiments have been performed using a simulation environment in which ray tracing is used to generate synthetic images for the stereo system

Link to ten short video episodes about groupwork

"Rob, Vikki, Shireen, Muzz and Delia have been randomly selected to work together to develop a presentation entitled 'The barriers to learning'. It's not an easy ride. The following 10 episodes show the journey, from their first meeting through to their impressions of the presentation and working together". Produced by the LearnHigher CETL Three areas covered by the site as follows Listening and Interpersonal Skills - the University of Leeds Oral Presentations - Brunel University Group Work - Bradford University

La pizarra mágica : marcas olvidadas del conflicto

La pizarra mágica es un juego típico para niños, en el que se puede dibujar y borrar todo. Sin embargo, cada trazo deja una marca, por invisible que parezca. Quién podría imaginar que un juguete como este tiene mucho en común con la historia de tres mujeres desplazadas por la violencia en Colombia: Minellys, María y Yanid. Este documental muestra los diferentes tipos de traumas producidos por el desplazamiento y la forma en que el Estado trabaja para mitigar esas marcas con las que conviven más de 5 millones de colombiano. Esas son las marcas olvidadas del conflicto que si no se atienden, seguirán produciendo consecuencias nefastas en las personas, la sociedad, la cultura y la historia colombiana.

Laser Safety in higher education - Classic video!

Vintage video (1986) on laser safety, presented by Dr. Gillian Rice. This is a 37 minute video, explaining the hazards which are likely to be encountered and ways to reduce those hazards in teaching and research laboratories in higher education. Presented in 5 parts: Part 1 (1:49) Laser radiation and the body Part 2 (8:49) Classes of laser Part 3 (13:32) Safety measures Part 4 (21:32) Other risks: precautions Part 5 (31:49) Summary

Additional Exam Responsibilities video

This video is for students with specific learning differences that mean that they are entitled to use a computer to type written examinations rather than writing them longhand. It show them how to use the special AER workstations that provide a cut-down version of Microsoft Word and absolutely no access to the Internet.

Laser Health and Safety Interactive Video

This short video is designed to make you think about the safety aspects of working with lasers within laser laboratories. Postgraduates and research fellows work with many different types of lasers in a variety of different experimental conditions. These lasers are often more powerful than those used as an undergraduate and require additional safety practices. The video was demonstrated to the EUNIS 2008 conference Aarhus, Denmark, and was a finalist in the Dorup E-Learning Award.
