Prediction of 3D stacking poses of supplemental wave-dissipating blocks based on existing block poses and physics engine

Abstract

The wave-dissipating blocks are stacked on the breakwater as a protective structure to protect beaches, ports, and harbors from the erosion of waves. However, the motion and corrosion of sea waves also cause irreversible damage to the blocks, causing these structures to sink and even ablate. Therefore, regular supplementary work is required to maintain the height of the breakwater. This study aims to accurately estimate the number of supplemental blocks and their stacking poses using a physics engine. In addition, we propose an estimation algorithm of new block poses stacked on the existing block models derived from UAV and MBES scanned points.
