A Hybrid Method for Indoor User Localisation Milan Redžić, Ciarán Ó Conaire, Conor Brennan, Noel O’Connor Abstract In this work we describe an approach to indoor user localisation by combining image-based and RF-based methods and compare this new approach to prior work [1]. This paper details a new algorithm for indoor user localisation, demonstrating more effective user localisation than prior approaches and therefore presents the next step in combining two different technologies for localisation in indoor type environments. Image matching and localisation The image matching uses the well-known SURF algorithm [2] which is implemented and installed on the N 95 cell phone. An array of correct matches between given image and set of images is formed and max value indicates the image with most matches. System Overview Experiments and Results Locations scattered throughout DCU(3 floors). Camaignr software [3] was used. Photos from various angles, rotation, scale were captured. The hybrid technique is based on applying image matching on the smaller set of locations, which are generated by applying Bayesian analysis to the RF signal strength readings.

River Water-level Estimation Using Visual Sensing E O’Connor, C O’Conaire, A. F. Smeaton, N. E. O’Connor, D. Diamond Water management is an important part of monitoring the natural environment and includes monitoring the water quality of coastal and inland marine environments. Visual sensing can help to overcome some of the problems associated with in-situ wireless sensor networks and provide context to what is being sensed. The development of a smart multi-modal sensor network will lead to a more robust and effective environmental sensing system. Image Data Examples of the challenging image data we are using, demonstrating disparate appearance due to varying rover conditions. We report on our initial work on using visual sensing to monitor a river environment. UNIVERSITY COLLEGE DUBLIN CITY UNIVERSITY TYNDALL NATIONAL INSTITUTE 21
