Multibeam Echosounder and LiDAR in Process of 360-Degree Numerical Map Production for Restricted Waters with HydroDron

Abstract

In order to increase the safety of inland navigation and facilitate the monitoring of the coastal zone of restricted waters, a model of multi-sensory fusion of data from hydroacoustic and optoelectronic systems mounted on the autonomous survey vessel HydroDron will be developed. In the research will be used the LiDAR laser scanner and multibeam echosounder. To increase the visual quality and map accuracy, additionally side scan sonar and rotary camera have been used. The main purpose of the research is to create the concept to develop new models of data processing from sensors, their comprehensive fusion and consistent visualization. This will allow to present data in the form of 360 degrees spatial maps for coastal areas. This kind of map enables the visualization of spatial data both horizontally and vertically, creating one spherical image of the terrain surface. The high level of product innovation determines its potential for commercialization.
