Instructions

This repository contains the implementation for the MBES Dataset class and data loader, the classical methods GICP and FPFH, as well as the code for metrics computation and evaluations.

The code use to run the learning-based models are found in the following repository forks:

• FCGF
• DGR
• Predator
• BathyNN

The dataset, pretrained models and evaluation results can be found here. Note that the dataset only contains the patches segmented according to the paper description. To construct a registration dataset, please consult main.py. If you want the exact data pairs and transforms as used in the paper, you can also extract these from the npz files containing in each method's evaluation results.
