| contents | A shoreline-estimation system using remote radar sensing and image-processing techniques Juan Carlos Vélez Jhonathan Posada Antonio Serrano José Manjarrés Juan Carlos Niebles Mauricio Pardo Ingeniería FPGA radar heat map based system seam carving This paper proposes a radar-based sensing system that estimates the coordinates for shorelines based on image-processing techniques. The proposed system provides shore estimations without appreciable loss of resolution and avoids the costs associated with bathymetries and/or satellite images. The system is comprised of a commercial radar, a GPS, and a heading sensor, which communicates to a central node that georeferences the radar measurements and runs the image-processing algorithms. A dedicated FPGA-based unit is implemented to interface with the radar internal signaling to extract and deliver the radar information. In the central node, a novel mathematical model is proposed for georefencing radar measurements to WSG-84 coordinates. A seam-carving-like algorithm is applied over the estimated coordinates to create a shoreline based on a probability heat map. The system performance is validated using official geographical information, showing that a continuous shoreline can be generated with a CEP of up to 6 m without incurring elevated costs. 2017 artículo científico 0012-7353 https://www.redalyc.org/articulo.oa?id=49650910045 https://www.redalyc.org/journal/496/49650910045/ https://www.redalyc.org/journal/496/49650910045/html/ https://www.redalyc.org/journal/496/49650910045/49650910045.epub https://www.redalyc.org/journal/496/49650910045/movil en http://www.redalyc.org/revista.oa?id=496 Dyna application/pdf Universidad Nacional de Colombia Dyna (Colombia) Num.200 Vol.84 |
