Btw did you guys saw sneak peek of MINI with RGB camera on YouTube? Revopoint made it happen… seems like they solved the color scanning issues in the final device. What could improve scanning human skin as well. As I see no brown, gold or yellow color issues anymore, wondering if they added infrared or software reprogramming only . The texture quality will be so much better than POP2 due to higher value of points , since each point represents color pixel . And the preview looks promising.
Speaking as an electronic engineer, I’d approach the issue by interleaving the capture. Pulse the blue light for 10-50ms and capture depth data (should be more than enough to capture raw data; it’s the custom chip’s calculations to generate the point cloud that take most of the time), then turn the blue light off and bring the color camera out of standby to grab texture info, then alternate back and forth. LEDs are not like incandescent bulbs, so they do not radiate after they’re turned off.
Easy peasy.
I suggested the same as there is no other way , you need to capture at least 1 photo per second, but from what I see there are 10 photos captured per second so something is off .
Hi! If it is not smooth, that’s fine, if necessary we can post-process, I guess? But is the beard and hair still invisible for the scanner or can you get at least the geometry of the face, even if the hairs are not well textured?
Would be very interesting - coming also from Kickstarter!
Don’t worry, I know what to expect from Home-Grade scanner, but it would be very interesting to know 
Thanks a lot!
The best way is to put gel or hair Spray on the hair and then baby powder so you don’t have lose hair for better tracking and capture .
With baby powder you can capture the dark hair well or any other hair color since it add volume to the hair .
I am working for years with professional human scan data and the quality of the mesh is above anything I was working with . No raw data from very expensive scanners looked so clean ever. So you can expect a lot better results .
The only downside of MINI and scanning humans is the short distance between the model and MINI . POP2 have higher range in distance so it is much easier .
In general MINI was not design for scanning humans , but nothing is impossible with little practice and patience.
Also pay attention that the data collected will be huge , so you will need at least 64GB of RAM if you want to scan whole head at once , or scan partials and merge it if you have not enough of RAM , it will be also time consuming .
You can also fuse the point cloud at 0.1mm it will take less RAM , it will do the job faster and you still ends with great volume accuracy and nice details .
That leaf scan is impressive ! Any problems with tracking as it went round the edges of the leaf?
Thanks Johnathan , the blue sticky stuff helped with the tracking , I was surprised how good it looked after . Not intentional results .
For something so thin it’s done a very nice scan!
I use the blu tack to help tracking sometimes, it’s quick, easy and works great
I also like the way it picked up the stitching on the material, is that leather ?
The blue tack is good , I like to stick my rings and coins with it too to the plate .
Yes the last image was leather , also very surprised that it picked up the surface and stitches that were really small .
I need to mesh the point cloud to see if more details shows up after .I really like how the android app fuses the point cloud , always so clean.
Here some tests on the distances between MINI and the object
The most far distance to scan anything between MINI and an object is 28cm / 11 inches
but that is not recommend working distance , just the maximum reach of the Depth Camera sensors resulting on a bad scan of course .
Distance 11 inches, 29cm / 290mm
The next one is in the “GOOD” range at around 9 inches / 22cm/220mm slightly above the recommended distance.
The next in the Excellent/Very Good recommended distance of 7.8 inches 20cm/200mm
as you see the details starting to pop up and the surface starts to be smoother.
And here we have the Excellent/Super Fine distance of 3.9 inches/ 10cm/100mm , most recommended for scanning very small objects
And here molar tooth crown.
The opening window size
at 10 cm/3.8"
At 20cm/7.8"
Personally my favorite distance is around 15cm / 5.9" from MINI to the object
at 22.8cm/9"
As you see the scanning area is very small , and not because of the projector resolution , but because of the angle the Depth sensor are mounted. The Blue light projector can cover much bigger capture area but is limited by the Depth sensor’s FOV that can’t be changed .
I hope you find it interesting .
Thank you, PUTV, for sharing the test results. 
I believe they are helpful to our MINI users!
You welcome Selina ! 
I forgot to add something , be careful with AESUB 3D Orange 3D spray on coins and gold/silver plated jewelry, it can corrode it . You need to clean it directly after scanning and not leaving on even if vanished , I learned the hard way when I leave it and after one month my two 1 dollar coins was ruined , oxidized and stained , one is still stained even after fine cleaning .
that is how they look like after 4 weeks , even a quarter was oxidized … I tested also Attblime on a quarter and so far there are no issue, the shine still on , but not the one with AESUB .
For coins I would suggest to use Zinc oxide mixture , but hey I was too lazy .
My oxidized $1 coins
Test using quarters , top Attblime, bottom AESUB after 1 week , the patina formed after the spray vanished . It seems to react stronger with copper.
I did not had any issues with pure Silver, Gold or Stainless steel using AESUB Orange
Dang… better wash my pewter dragon.
You better … on one of my dollar coin got so deep I could not restore it back yet , looks like after acid bath.
I need to drop them a letter as that is not acceptable.
Also my military bronze coins got little discolorations . But copper was the worse .
Seems like Attblime using complete different formular that why no reactions.
Power washed on the patio, but I did not notice any deterioration in the last 6 weeks.
And it’s certainly not because I used too little. Guess pewter is non-reactive for this chemical combo, but you’re right to complain to AESub’s manufacturer.
This is very important. Thank you. And I am sorry for what happened.
Thank you very much Selina 
Speaking as not any sort of engineer, that sounds like techspeak for exactly what I had in mind when the whole RGB/ no RGB argument started
Except I phrased it, in my head, as “alternating frames”.
Hi guys , it was a while since my last post ,
I am in process of beta testing my beta evaluation version of Revo Scan to push MINI to the limits beyond it’s specifications with some great results so far. This include very small scans and big like body parts as well and so far everything looking great 
faster processing time for both fuse and meshing , I hope it will get approved soon but need to do more tests this weekend to make sure the quality is there on each level .
I will post some results soon …
I had my short summer break, but back on track again .
Hopefully next week I would be able to guide you with some new tips on the new MINI RGB functions as well.
It going to be interesting days ahead! Stay tuned !
