Paper Abstract

One approach to the design of a non-contact, automated system able to measure in three axes is based on triangulation. A system comprised of a CCD sensor and laser source oriented to each other in a triangulation configuration will provide range information. Taking this arrangement and scanning it with the use of a rotating polygonal mirror over a moving conveyor allows for three axis measurement. There are many considerations and parameters that must be taken into account when such a system is designed. The most critical parameter is the triangulation angle which has direct effects on resolution, working distance, and the size of the completed unit. A method is presented to design a system that will measure the length, width and height of a moving object. The genal approach is covered and the major parameters to be decided upon are explained.
