Creaform 3D Scanning: Colormap, the Quick Go/No-Go of Inspection
Colormap, the Quick Go/No-Go of Inspection
The HandyScan 700 3D Scanner is a great tool for inspecting parts for Quality Control engineers. Using VxElements, PPAP inspection reports can be created being as simple or as complicated as needed. After importing a CAD model, either .iges or .stp, the scan can be compared to the “perfect” CAD model. One of the useful tools within VxElements is the ability to create a colormap of the differences between the CAD model and the scan. This can be based on a surface best fit reference frame or a datum reference frame. This can be used as a quick go/no-go of whether a part overall is within inspection tolerances.
The error distribution can be changed to create a meaningful colormap that will show how the scanned part deviates from the CAD.
