Abstract

A system for determining a position of a light fixture that projects a beam of light on to a stage to form a first beam pattern on the stage includes an observing device located at a predetermined position relative to the stage to observe the first beam pattern. The system also includes a controller in communication with the observing device. The controller is configured to capture from the observing device an image of the first beam pattern on the stage, determine a major dimension and a minor dimension of the first beam pattern from the image, and calculate a position of the light fixture based on the major dimension and the minor dimension.
