Laster Pointer

Laser Ponter Tracking System

This is an old project executed by John Hu about 4 years ago.

Laser Pointer Tracking System uses normal web camera to detect the laser pointers. We use computer vision techinology to find out the position of laser pointers in camera and covert them to computer coordinate system. It is comprised of camera driver, v4l2, blob detection, blob tracking, gesture detection, and mouse/keyboard controller modules.

The first example is to use laser pointer to control a power point presentation:
