Difference Measurement

Our 3D Metrology solutions utilize automated comparisons of high-resolution 3D part scans against the original CAD model, as well as additional 3D scanning services for quick and accurate difference measurements.

3D Scan vs. CAD Model

3D scans of the piece part containing millions of data points are compared to ideal CAD models to verify dimensional accuracy of the entire part, or a specific feature.

3D scans containing millions of data points are captured of the piece part to be inspected and overlaid on top of the CAD model

Advanced difference algorithms compare millions of data points for differences

Difference results are output and displayed in an easy to understand psuedo color model showing the amount of difference in various units of measure (thousandths, microns, etc…)

3D Scan vs. 3D Scan

In addition to 3D part scan vs. CAD model comparison, 3D part scan against 3D part scan comparison is possible by overlaying high resolution scans of different parts to verify production consistency or to compare different manufacturing processes.

Full 360° 3D Scan Comparison

High precision rotation devices combined with 3D scan sensor technology allows for capture of full 360° 3D scans. These 3D piece part scans can then be compared against the ideal CAD models or other 3D scans to inspect even the most complex geometries.
