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.

Dependent claims

A non-contact scanning system comprising:

a common base for carrying said fixture assembly and said gantry assembly;
a fixture assembly for carrying a work piece to be scanned;
said fixture assembly moveably mounted relative to said common base to provide at least three degrees of freedom of movement relative to said common base,
a scanner assembly for scanning a work piece, said scanner assembly including a slide assembly and a scanner that is moveably mounted relative to said slide assembly;
and
a gantry assembly, carried by said common base, said gantry assembly for carrying said scanner assembly so that the workpiece carried by said fixture assembly can be viewed by said scanner assembly, said gantry assembly including a radius arm formed in a generally arcuate shape that enables the angle of the scanner assembly to be varied relative to the workpiece;
wherein the scanning system is able to make a three dimensional image of the workpiece.
