Face detection using OpenCV. This system work for taking attendance by seeing your face, or identify your face for security purposes.

EXPANDED TECHNICAL DETAILS

Computer Vision Hardware Bridge

This project bridges the graphical power of OpenCV on a PC with an Arduino-based physical hardware reaction.

  • Python/OpenCV Cascade Pipeline: A Python script captures video from a webcam and uses the "Haar Cascade" classifier to detect human faces in real-time.
  • Hardware Coordinate Mapping: Python calculates the (X,Y) coordinates of the center of the face and sends them over Serial to the Arduino. The Arduino then maps these coordinates to two servo motors (Pan/Tilt), causing a laser or an "Eye" to follow the user's face.

Speed Optimization

  • Region of Interest (ROI) Tracking: To increase frame rate, the Python script only scans the area around the previously detected face, allowing for high-speed tracking even on entry-level hardware.
