Camber

Camber is an open-source structural health monitoring (SHM) platform for bridges and civil infrastructure. It is a desktop application that ingests sensor data (vibration, displacement, strain, temperature, …), manages assets and sensors, evaluates thresholds, and visualises status on dashboards, charts, and a map.

Where existing open-source SHM tools are signal-processing / modal-analysis libraries, Camber is the operational platform layer above them — asset management, monitoring, and data handling — as open, vendor-neutral software.

Camber was previously called BridgeQ.

Features

• Asset & sensor management (full CRUD; rename / delete)
• Sensor-file import — tidy and wide/multi-channel CSV, auto-detected and locale-robust, with a preview before writing (via camber-convert)
• Threshold evaluation & status
• Time-series charts with a Live mode + POST /measurements ingest API
• Frequency analysis — FFT amplitude spectrum + spectrogram (numpy)
• Built-in sample dataset (Data ▸ Load sample data) so first run just works
• Map view (QtWebEngine + Leaflet)
• Local SQLite storage, multi-project database switching
• CSV / XLSX / PDF export
• Local HTTP extension API on 127.0.0.1:8765
• Rotating error log + crash-safe exception handling (Help ▸ View logs)

See docs/ROADMAP.md for the honest take on data-scale limits and the path to production (storage, streaming, analysis depth).

Quickstart

# Windows / PowerShell
python -m venv .venv
.\.venv\Scripts\Activate.ps1
pip install -e .
camber                      # launch the desktop app
python scripts\run_dev.py   # run the local API only (no Qt) on :8765

The open data format & camber-convert

Camber reads an open, vendor-neutral data format produced by camber-convert, a separate MIT-licensed converter published to PyPI. Keeping the converter standalone and MIT-licensed lets other tools adopt the open format freely.

License

Camber is free and open-source software, licensed under the GNU Affero General Public License v3.0 or later (AGPL-3.0-or-later). See LICENSE for the full text.

In short: you are free to use, study, modify, and share Camber. If you distribute a modified version — or run a modified version as a network service — you must make your source code available under the same license. This keeps Camber free for everyone.

Camber bundles the separately-developed camber-convert library, which is licensed under the more permissive MIT license so that other tools can adopt the open data format freely. See NOTICE for attribution and third-party license details.
