1. Abstract
The Seat-Belt Detection System is an AI-based application that uses computer vision and deep learning to identify whether vehicle occupants are wearing seat belts. The system analyzes images or video footage captured by cameras and detects seat-belt usage based on visible visual features. When a potential seat-belt violation is detected, the system can generate an alert or flag the event for review. This project aims to support road safety monitoring and improve awareness of seat-belt compliance.
2. Objectives
- To detect vehicle occupants in images and video streams.
- To identify visible seat-belt usage.
- To automate seat-belt compliance monitoring.
- To analyze vehicle footage in real time.
- To reduce manual monitoring efforts.
- To flag potential seat-belt violations for review.
- To support road safety initiatives using AI.
3. Existing System
Traditional seat-belt monitoring relies on manual traffic inspections, security personnel, or built-in vehicle sensors. Manual monitoring can be time-consuming, while basic sensor-based systems may not provide centralized visual monitoring across multiple vehicles.
Disadvantages of the Existing System:
- Requires manual inspection in some environments.
- Difficult to monitor multiple vehicles simultaneously.
- Potential violations may be missed during manual observation.
- Limited centralized monitoring in basic systems.
- Results may be affected by poor visibility.
- Manual review of recorded footage can be time-consuming.
4. Proposed System
The proposed system uses AI-based object detection and image analysis to identify vehicle occupants and classify visible seat-belt usage. It processes camera footage, examines the occupant's upper body region, and flags potential cases where a seat belt is not detected.
Key Features:
- Vehicle occupant detection.
- Seat-belt and no-seat-belt classification.
- Real-time video analysis.
- Visual highlighting of potential violations.
- Detection timestamps and event logging.
- Dashboard for viewing detection results.
- Optional alerts for authorized monitoring personnel.
- Support for recorded videos and compatible camera streams.
5. Implementation Procedure
- Requirement Analysis: Define the detection requirements, vehicle types, and camera placement.
- Dataset Collection: Obtain labeled images or videos of occupants wearing and not wearing seat belts.
- Data Preprocessing: Resize images, annotate relevant regions, and prepare training and testing datasets.
- Environment Setup: Install Python, OpenCV, and the required deep learning libraries.
- Model Selection: Select a suitable object detection or image classification model, such as YOLO.
- Model Training: Train or fine-tune the model using labeled seat-belt images, if necessary.
- Occupant Detection: Identify the driver or passenger in the camera frame.
- Seat-Belt Classification: Analyze visible clothing and seat-belt patterns to classify apparent seat-belt usage.
- Violation Flagging: Flag potential no-seat-belt cases for authorized human review.
- Dashboard Development: Display video frames, classification results, and event logs.
- Testing and Deployment: Evaluate detection accuracy under different lighting conditions, camera angles, clothing types, and seat-belt visibility.
