ATS600 SVI Measurements

Surface Vector intersection Measurements

The ATS refectorless measurement capability provides a means to precisely measure a point location on a surface. Vectors normal to that surface can be used to identify exactly where to measure on an actual part regardless of thickness variation. This corrects for a potentially significant shift in the location of the returned point depending on the incidence angle to the part if nominal points on the part are used rather than vectors. SVI (Surface Vector Intersection) measurements provides an auto-measure function which can be used for this type of application.

If you have a CAD model, its very easy to construct a grid of points on a surface using: Points Evenly-Spaced on Mesh Surfaces in UV

Then you can query those points to the CAD to build Vectors normal to the surface.

 

For settings, go to the Gear Tool (General Settings) in the main tracker interface window, and hit [Leica ATS] button

To initiate this measurement, just go to the SA Instrument menu, and select Instrument>Automatic Measurement > Measure Batch of Vectors

Measurement details will include the “Max Expected Part Deviation” and “Threshold” values used, and the resultant point’s distance from the vector.
