The current approach is to use “Integration Spheres”, to asses the point to point distance performance of a laser scanner. Two approaches exist:
1) Measure an artifact from 2 sides . Side A measured by a reference instrument (IE) Laser tracker. And side B the instrument under test (laser scanner).
2) Use a scale bar, measure SMR locations. Then replace the smr’s with a sphere and attach the integration sphere.
