Method to determine the Uncertainty of the readings of a Laser Scanner

Hi everyone,:bigwave:

We try to perform a Gauge R & R on a LASER SCANNER (Krypton, Leica, or any other type of Laser Scanner)

With 'standard' instrument, we can measure 10 points (it's even possible with CMM & Laser Tracker and very easy with micrometer & caliper....), by 3 users, 3 times, then the calculation.....etc...etc....:yes:

But with Laser Scanner, since we have thousands (even millions) of points when scanning a surface, how can we compare THOSE points from scan to scan
We end up with 9 scans of thousands of points each, that's a lot of points to compare...:mg:

So, what would be a good method to ananlyse, and determine the uncertainty of the readins of a laser scanner...???:confused:

Thanks!!:thanx:

Jeenan!!!

Hi Jeenan

Do you have x,y,z data from the laser scans? If so, perhaps you can carry out 3 scans per operator, then select a small set of data from each file corresponding to the same points on the surface.

Let's suppose you have done a CMM measurement and you measured 10 points in a line, at 1cm intervals. If you now do a laser scan, is it possible to pick the same 10 points from the thousands in the raw scan file?

You may need to average a subset of the points over a small area. For the sake of discussion, could you average the points over a 0.5mm square area for each of the 10 points previously measured by the CMM?

You would then have a direct comparison between the same points measured by different methods.
