🛡️ AI REBA Auditor An AI-powered ergonomic assessment tool built for Automotive to automate the Rapid Entire Body Assessment (REBA) process. Using real-time computer vision, the app identifies skeletal landmarks to calculate postural risk scores instantly.
🚀 Features Real-time Tracking: Uses MediaPipe Pose to track 33 body landmarks without special hardware—just a standard webcam.
Automated REBA Scoring: Instant angle calculation for:
Trunk: Flexion, extension, and upright positioning.
Neck: Head tilt and alignment.
Upper Arms: Reaching and elevation metrics.
PDF Audit Reports: Capture a snapshot of high-risk postures and download a professional audit report for safety records.
Firewall Bypass: Integrated with Metered.ca TURN servers to ensure connectivity on strict factory/corporate Wi-Fi networks.
🛠️ Tech Stack Frontend: Streamlit
AI Engine: MediaPipe
Video Streaming: streamlit-webrtc
Networking: STUN/TURN via Metered.ca (Open Relay)
📦 Installation & Local Setup Clone the repository: git clone https://github.com/your-username/geely-reba-auditor.git cd reba-auditor
Create a virtual environment (Python 3.11 recommended): python -m venv venv source venv/bin/activate # On Windows: venv\Scripts\activate
Install dependencies: pip install -r requirements.txt
Run the application: streamlit run app.py 🔐 Deployment Configuration When deploying to Streamlit Community Cloud, you must add your Metered.ca API Key to your Secrets:
Go to your App Settings on Streamlit Cloud.
Navigate to Secrets.
Add the following:
Ini, TOML
METERED_API_KEY = "your_pk_key_here"
📖 How to Use Positioning: Stand 2-3 meters away from the camera, showing your profile (side view).
Metadata: Enter the Operator ID and Workstation in the sidebar.
Audit: Watch the live "Risk Score" metrics. If the score turns red, the posture requires immediate intervention.
Export: Click "Generate Audit Report" to save the findings as a PDF.
🤝 Contributing This is an open-source project created for non-commercial ergonomic safety. Contributions to include Leg or Wrist scoring logic are welcome!
