Abstract
The present invention provides a dimensioning system for determining the minimum size box necessary to enclose an object traveling on a moving conveyor. The dimensioning system is comprised of a light source which generates a scan beam that is moved by a mirrored wheel. A line scan camera whose field of view tracks the moving scan beam receives images of the scan beam and outputs a signal which is processed to compute a three dimensional box structure of the scanned object.
Claims8
A method for determining the dimensions of one or more objects on a conveyor, comprising the steps of:
- a) directing light beams onto the conveyor at identified locations;
- b) detecting interference with the light beams striking the conveyor;
- c) collecting time and location data associated with the detected interference for the duration thereof;
- d) examining the collected data and generating an interference outline;
- e) determining if the interference outline represents one or more objects;
- and
- f) outputting a signal based on the determination of step e.
