aquamvs 1.5.2

Multi-view stereo reconstruction of underwater surfaces with refractive modeling

AquaMVS

Multi-view-stereo (MVS) reconstruction of underwater surfaces viewed through a flat water surface, with Snell's law refraction modeling.

Status

v1.3.5 released. AquaMVS is feature-complete for the v1.0 milestone and available on PyPI. The API is considered stable; breaking changes will follow semantic versioning.

What it does

AquaMVS is a companion library to AquaCal. It consumes calibration output and synchronized video from above-water cameras to produce time-series 3D surface reconstructions. The pipeline handles the unique challenge of cameras positioned in air observing underwater geometry, accounting for refraction at the air-water interface using Snell's law.

Key Features

• Refractive ray casting through air-water interface (Snell's law)
• Dual matching pathways: LightGlue (sparse) and RoMa v2 (dense) for different accuracy/speed tradeoffs
• Multi-view depth fusion with geometric consistency filtering
• Surface reconstruction (Poisson, heightfield, Ball Pivoting Algorithm)
• Mesh export (PLY, OBJ, STL, GLTF) with simplification
• Full CLI and Python API for pipeline users and custom workflow developers

Quick Start

from aquamvs import Pipeline

pipeline = Pipeline("config.yaml")
pipeline.run()

See the full documentation for configuration details, API reference, and examples.

Installation

AquaMVS requires several prerequisites (PyTorch, LightGlue, RoMa v2) to be installed first. AquaCal is installed automatically as a dependency.

See INSTALL.md for complete installation instructions.

Quick summary:

# 1. Install PyTorch from pytorch.org
pip install torch torchvision --index-url https://download.pytorch.org/whl/cu121

# 2. Install git-based prerequisites (LightGlue, RoMa v2)
pip install -r requirements-prereqs.txt

# 3. Install AquaMVS (pulls AquaCal automatically)
pip install aquamvs
