Summary

A robust image processing framework has been proposed for underwater robot-based construction environment monitoring, specifically addressing complex degradations in real marine environments. This framework tackles issues beyond conventional absorption and backscattering, such as depth-dependent forward scattering blur and particle-induced marine snow. It employs a staged processing pipeline that models background degradation via depth-aware forward scattering and foreground degradation using realistic marine snow patterns extracted from real images. The resulting synthetic data retrains an existing Joint-ID network without architectural changes, enabling isolated evaluation of dataset realism. A lightweight post-processing scheme further enhances contrast and structural clarity. Experiments on real underwater datasets from Korean coastal environments demonstrate consistent improvements in visual quality and UIQM scores, effectively reducing the synthetic-to-real gap.

Key takeaway

For Computer Vision Engineers developing underwater robotic systems, you should prioritize explicit modeling of complex environmental degradations like depth-dependent forward scattering and marine snow in your training data. This approach, demonstrated to improve visual quality and UIQM scores on real datasets, will significantly reduce the synthetic-to-real gap for your models. Incorporating staged degradation pipelines can lead to more robust and practically applicable vision systems for construction monitoring and similar marine operations.
