To make up for this shortcoming, the collaborative project seeks to develop an innovative acoustic 3D imaging and surveying system designed to implement bionic findings from how bats and dolphins process signals in order to, for the first time, obtain and analyze in real time complex acoustic spatial and spectral information. The process is based on the use of specially configured ultra-broadband signals and modern analytical procedures. It implies a chain of innovation that comprises practically all structural and functional levels, and will establish a new level of system performance in underwater sensors overall.
Fraunhofer IGD is taking part in the subproject “Application-specific ultrasonic transducer and real-time capable data processing and visualization” by visualizing and performing detailed analyses on the collected data. Modern processing and visualization technologies are being developed and combined with special analytical tools for this purpose. This will allow an operator to navigate a (virtual) display space in 3D with, for example, VR goggles, and to focus on specific sectors, shells and objects as well as select/study relevant properties, now in color. One area of application could be in the mining of manganese nodules, which currently require time-consuming manual measuring of the area and subsequent soil samples. The “acoustic eye”, installed on autonomous carrier vehicles (USVs, AUVs, etc.) as an intelligently adaptive sensor system, can take over and make easier the measuring, detection and precise definition of manganese deposits.
