Overlapping and noisy surface issues

I’ve been using my mini for a difficult-to-scan part. When I scan, I have to do the part in about 20 scans. Aligning and cleaning them up is proving to be very difficult and time consuming. The main issue is the noise I’m getting in the scan and how that is affecting the generated mesh. It’s very difficult to clean these up. Any thoughts? I need help!

Hi @The3DProfessor

You scanning an object that don’t need more resolution than 0.2mm

Noises are created from shiny surfaces , you may use too high settings while fusing and meshing .

MINI is created to scan mini objects like rings , and very fine object , scanning big objects will induce artificial points and noises if fusing and meshing is set at highest settings .

I propose you use Advanced fusing mode set at 0.2mm for big objects above 150mm and 0.1mm for 60mm and at 0.08mm for smaller than 60mm

The FOV of MINI 1 is very small and it needs lots of tracking points ( object features) to be able to proper align all frames . Overlapped frames are caused by over scanning the object , use a single shot mode ( option is under play/start button ) it will help you in reduction of overlapped points.

Mesh you scans according the fused points , if you fused at 0.2mm make sure your meshing Grid settings are reflection 0.2mm and no lower or higher .

This way you will reduce artificial points and lots of noises, keeping the most details intact .

Make sure you prepare your scan ing surfaces with 3D spray to avoid any shiny reflections as that can induce micro noises .

If you follow my advice and still have bumpy results , I will advice to calibrate the scanner using the board . But before that make sure you follow the fusing and meshing settings first to archive the best results and reduce the time of cleaning to almost none .


Thank you for the response. I’ll go back and give it a try and let you know how it works.
