This is a guide for FARO scanner setup with VTube-LASER.

Contents

Results from Extensive Research

VTube-LASER has sophisticated analysis tools (like DCP - Dual Cylinder Fit) that can tell if the incoming data is reasonably good. Because of these built-in tools, we have discovered some useful operating principles for best practices in FARO scanner setup.

The information on this page is the result of our research into how best to scan and calculate tube cylinders. The principles here probably apply to other shapes as well - but we know for sure that they apply to measuring at least cylindrical shaped surfaces.

PRINCIPLE: LLP Camera Exposure Modes Depend on the Scanner Version

The diagram on the right shows the workable exposure settings that are acceptable with the FARO scanners when measuring tube shape.

In some cases the older version scanners can use AUTOMATIC modes, but the cylinder calculation is not as reliable in these modes.

For version 2 and version 3 scanners, it is almost impossible to pass the 4-level cylinder fit-test in VTube-LASER 2.8 and newer when scanning tubes. The only solution in this case is to use FIXED mode in the FARO Laser Line Probe Control window.

FIXED is better than AUTOMATIC Exposure

An important principle that we've discovered is that, in all cases, FIXED mode is more reliable than AUTOMATIC mode in returning consistently accurate surface points. This is especially true when measuring a tube on a CUT PLANE. The Cut Plane may interfere with the automatic exposure mode if the Cut Plane reflectivity is much different than the tube surface reflectivity.

An important principle that we've discovered is that, in all cases, FIXED mode is more reliable than the AUTOMATIC mode in returning consistently accurate surface points. This is especially true when measuring a tube on a CUT PLANE. The Cut Plane may interfere with the automatic exposure mode if the Cut Plane reflectivity is much different than the tube surface reflectivity.
