Abstract

A non-contact scanning system for three dimensional non-contact scanning of a work piece is disclosed for use in various applications including reverse engineering, metrology, dimensional verification and inspection The scanning system includes a scanner carried by an arcuately configured gantry assembly and a fixture for carrying a work piece. The gantry assembly includes a fixed arcuately shaped gantry member and a telescopic arm that is movable in an arcuate direction relative to a rotary table that carries the object to be scanned. A scanner is mounted on the end of the telescopic member and is movable in a radial direction. Objects to be scanned are mounted on a rotary table that is also movable in an X-Y direction or alternatively in the X, Y and Z directions under the control of a motion control subsystem, a machine control user interface subsystem and an image capture. The configuration of the scanning system in accordance with the present invention provides a spherically shaped scanning envelope which facilitates three dimensional modeling of the work piece.

Claims

1. A non-contact scanning system comprising:

a fixture assembly movable in at least two linear axes and rotatable about a third axis for carrying a work piece to be scanned;

a scanner for scanning a work piece; and

a gantry assembly for carrying the scanner formed in a generally arcuate shape for use in creating spherically shaped scanning envelopes.
