1. A method for calibrating a three-dimensional space, said method for use with a machine vision system, said machine vision system including tracking means for tracking objects within said three-dimensional space, said method comprising the steps of:

  • a) moving at least one pair of indicators spaced apart by a known distance through said three-dimensional space at a known speed;

    b) tracking said at least one pair of indicators with said tracking means through said three-dimensional space; and

    c) mapping pixel space to said three-dimensional space based on the location of said at least one pair of indicators within said pixel space and said known, constant speed of said at least one pair of indicators.
