Seafloor litter field off the French Mediterranean coast (43.078°N;6.458°E): 3D scene and imagery
Litter site at the seafloor, off the southern French Mediterranean coast (43.078°N;6.458°E), at a water depth of ~600 m This litter field was surveyed using the HROV Arianne in 2017, deployed from N/O L’Europe, and equipped with a vertical electronic still camera. Two datasets are provided. First, the survey imagery, under a folder named carthorov_dump, that consists of 303 images (jpeg format) and an associated navigation file in dim2 format. Second, 2 folders with 3D textured models of the site (obj format), each with a kml file for georeferencing, and an geotiff orthomosaic. A first model is the result of processing imagery without data correction (folder WithoutAnyCorrection). A second model is processed with image colour correction (folder WithColorAndIlluminationCorrection). This dataset is one of several released with a paper by Arnaubec et al. (submitted March 2021, Computer and Geosciences) presenting the Matisse image processing software and the 3DMetrics Visualization and analysis software and released as open source (ref Github to come).
