Automated two-dimensional position measurements with computer vision

摘要

A computer vision system is presented that can be used to acquire position data for an experiment where human observations have traditionally been used. A simple algorithm based on color discrimination is used to automatically locate an object of interest. Experiments can be monitored in real time using inexpensive cameras. Examples are given to illustrate the applicability of this system for autonomous data acquisition. (C) 2007 American association of physics Teachers.
