Smart Sensors System Based on Smartphones and Methodology for 3D Modelling in Shallow Water Scenarios

The aim of the paper was implementation low-cost smart sensors for collection bathymetric data in shallow water and development a 3D modelling methodology reconstruction natural artificial aquatic scenarios. To achieve aim, system called GNSS > Sonar Phone System (G S P Sys) implemented to synchronise sonar (Deeper Smart Sonars CHIRP+ Pro+ 2) with an external receiver (SimpleRTK2B) via smartphone. performances G Sys Deeper were studied through specific tests. Finally, data-driven method based on machine learning approach mapping developed produced by Sys. proved be flexible, easily implementable capable producing models surfaces submerged structures centimetre accuracy precision.
