Dfodaro - Showcase - Revopoint MINI 2 3D Scanner - Art - Cultural Heritage

Hello everyone
I have started to familiarise myself with the new MINI 2. As an initial test I scanned an paperclip. The paperclip was prepared with a 3D scanning spray.
The scan was carried out by placing the object on the turntable and scanning in continuous mode.

Below the version made with the MINI 1.

In that case, I had taken two separate scans, which were merged later (the FOV being smaller than the MINI 2, tracking was lost by doing a full rotation).

In the case of the scan carried out with the MINI 2, this procedure was not necessary, as full rotation was performed. The RAW data was cleaned before fusion and then meshed.

Comparing the two scans, it seems to me that in the MINI 1 version the paperclip thickness is thinner than in the real object, whereas in the MINI 2 version this is not the case. See the picture below.

Hi!
nice showcase- again!:slightly_smiling_face:

was it the same scanning spray and applying method used on both paperclips? Which scanning spray(s) have you used?

Did you measure the deviation on scanned thickness vs true thickness?

Best regards

Thanks Ivan!

the spray is Aesub (long-lasting)

To make this measurement I would have to look for the file of the first scan (I don’t know if I will be able to retrieve it).

Hello everyone,
now a scan (in colour) of a sea shell, with fine detail.
Scanned on the turntable, performing full rotations and changing orientation.
Daylight, flash off.

Hi Davide , I was waiting for your clip ! :blush:
But MINI 2 can go already beyond that what makes its Accuracy much better than specifications sheet .

Keep up the good work !

@dfodaro What is the largest object you can scan without too much hassle?

What do you mean “ without too much hassle?”
From the revopoint scanner series, the MINI 2 is designed for small objects, but you can also use it for medium-sized objects. You have to consider that the MINI2 has a Working Distance 120 - 250 mm and Single Capture Area at Furthest Distance 168 x 132 mm. With the previous version (MINI 1) which had a smaller FOV and a shorter working distance, I used it to scan a 70cm tall sculpture, which on the MINI 2 should be much easier.

By hassle, I mean frequent loss of tracking, slow scanning speed, and so on. For me, 70 cm would be enough as I want to scan small to medium objects. For larger objects I can use my iphone or the einscan hx. My mini 2 should arrive mid next week. Thanks for the info.

You should not scan bigger objects than 28cm around 11 inches, the reason is that scanning too big objects with MINI series will reduce the resolution while fusing and meshing to avoid monster mesh and run out of memory . In short you will not archive the highest accuracy scanning with big objects .
MINI series is created to scan mini objects

On top because if the smaller FOV you will need features to be very closer to each other to avoid love if tracking , how smaller the FOV how more features it needs per FOV area .

@PUTV Can this feature be turned off? (Also where can I find more info about this?)

I have a pretty powerful machine for work and for the more expensive scanner, so RAM is not a problem. But the hx is not nearly good enough for small objects, thats why I needed the mini.

It’s not a feature to be turned off , the software is not designed to handle this kind of sizes , not even for Blender or Zbrush .

Fusing and meshing so big scans at that level of accuracy is not even nesesery so waste of resources .

Trust me , you don’t need that , bigger not always means better .
Go by the suggestions of the software to have the best results according to the volume .

When you fusing using advanced mode always use the best settings and according to that the meshing settings .

Start new thread when you start your progress and I will guide you , I don’t want to disturb the showcase of @dfodaro anymore .

To appreciate the level of detail that can be achieved with the MINI 2, here is a scan of the same sea shell and a scan made with the (fantastic) MIRACO in near mode. The settings are the same and the procedure used for scanning are identical.

From a paper clip to a Jug. Would you say the improved larger FOV helps?

The wider FOV was essential to facilitate scanning . The scanning of the vase was done in a single session, using the turntable and tripod, raising the scanner after each turn.
