Welcome to our guide on building a revolutionary Drowning Detector using YOLO (You Only Look Once) object detection technology. This project aims to enhance safety around swimming pools by providing real-time monitoring of individuals’ positions, allowing for quick responses in case of emergency situations.

What You Need

• Raspberry Pi: The brain behind our operation.
• Raspberry Pi Camera: To capture the underwater images.
• Appropriate Underwater Case: To protect the camera from water damage.
• YOLO Pre-Trained Model: For detecting individuals in the pool.
• Requirements File: Contains the necessary packages to run the project.

How It Works

This system employs an intuitive algorithm to detect if someone is in distress in the pool. Here’s how the process can be likened to a lifeguard on duty:

• The lifeguard (Raspberry Pi) scans the entire pool (monitors the camera feed) for swimmers (people).
• When the lifeguard spots a swimmer, they draw a blue rectangle (bounding box) around them, just like marking a swimmer who seems to need extra attention.
• For the next 10 seconds, the lifeguard keeps an eye on the swimmer’s position. If the swimmer remains in approximately the same spot (which could indicate distress), the lifeguard turns their attention to red markers (changes the rectangle to red) and sends out an alert (displays ‘DROWNING’).
• If the swimmer moves above the water (indicating they are safe), the alert is rescinded (the word ‘DROWNING’ disappears).
• Furthermore, the system assesses the swimmer’s posture: if they appear vertical (indicating potential drowning) versus horizontal (indicating normal swimming), the lifeguard can make a more informed decision.

Installation Steps

To set up your Drowning Detector, follow these steps:

pip install -r requirements.txt

Ensure you have all the necessary components connected and configured before proceeding with the code.

Troubleshooting Tips

If you run into issues while installing or running the program, consider the following solutions:

• Camera not detected: Ensure your Raspberry Pi Camera is properly connected and recognized by the Pi.
• Errors during installation: Double-check the requirements.txt file for any missing packages or dependencies.
• Incorrect object detection: It might be beneficial to revisit the clarity of camera positioning and lighting conditions, as these factors can affect YOLO’s performance.
