Sistema de Análise e Monitoramento de Estruturas Submersas de Baixo Custo

Abstract

Analyzing and monitoring underwater structures is still a challenge for humanity. A Remotely Operated Vehicle (ROV) equipped with sonar is a feasible alternative for assessment of structures in harsh environments. However, the cost associated with this equipment is high. Therefore, this work presents an innovative low-cost device capable of performing analysis and monitoring of submerged structures, using a Mechanical Scanning Imaging Sonar (MSIS) sonar to generate acoustic images, and carry out the 3D reconstruction of the analyzed surface. The use of sonar makes the measurements independent of ambient luminosity and is not affected by water turbidity. Experimental results show that the proposed device is suitable for analysis and monitoring of underwater structures.
