Project overview

We co-developed a prototype using OpenCV, dlib, and Eye Aspect Ratio to detect prolonged eye closure. Driver-specific recognition and temporal filtering helped distinguish fatigue indicators from ordinary blinking.

The vision processor communicated over TCP/IP with a ROS-based controller on a Jetson Xavier-powered vehicle. A multiplexer coordinated manual and autonomous control, supported by steering-wheel inputs and LiDAR obstacle detection.

My contribution

Computer-vision development, communication between the vision processor and robotic controller, performance benchmarking, and technical report co-authorship.

Evaluation

29.7 msMean internal switching latency
15 trialsPrototype switching evaluation

The prototype recorded an average 29.7 ms internal control-switching latency across 15 trials. Hardware comparisons on Raspberry Pi and MacBook Pro M1 examined processing delays and real-time detection bottlenecks.
