Chasing microns - OpenScan Mini accuracy test part 2
TLDR: I improved the setup and got myself some highly accurate steel spheres with nominal diameter of 20 and 25 mm ± 0.0025mm. I used the OpenScan Mini to scan a scene with both spheres, scaled it using a reference measurement from one sphere, and analyzed the diameter and surface deviation of the second one. I reliably get a diameter of ~20±0.03mm as well as a surface deviation within 2σ = 0.03mm I knew that my latest post claiming a bold 0.008mm accuracy made a very click-
