I’ve read through everything and am grateful you’ve shared so much trail and error you’ve gone through. I just started scanning for myself and I have a couple of questions since you’re the expert. I’m trying to scan an upper body of someone who has long hair and a beard and I know that adds a new level of difficulty to it. I’ve bought your suggested turn table and web cam mount. But still having some issues. So
I’m doing the scan with one rotation being about 50-60 seconds. Did I understand right that you stop and fuse points after each rotation?
After stopping the scan I can never get it to track again when I start. Is this common? Or do you have any tips to try and start it again? Its especially hard when I try to adjust the webcam mount
After you scan do export the point cloud into revo studio and do all the editing there? Or do you mesh in revo scan?
Sorry if I’m repeating already asked questions and thanks again for your help.
While I’m waiting I’m going to go watch some of your youtube videos.
That is a matter of personal preference. It becomes more advisable if Revo Scan is running on a smart phone with limited RAM. It is not a major concern if you are using a computer with 8-16 GB of RAM.
It is easiest to resume tracking if you start at the same position where you stopped on the first scan. In any case, you must have a significant amount of overlap between the first scan and the second in order for the scanner to coordinate.
Revo Studio can perform the Mesh operation with higher quality than Revo Scan. It’s your choice which to use, based on your needs and preferences.
Since Jeff already answered basically the questions .
What I do whipe scanning full body at once is scanning each rotation 360 frames and moving it down to next sections , usually I have 10 sections so around 4000 frames for full body scan 2m / 6.3ft person , it may be less for shorter of course with less sections .
I do not stop and fuse it as you will be never able to find the tracking again , unless you scanning a figure from stone . With humans it is very hard , so continue scanning the whole person at once if possible .
Keep the hands as close as you can , palm on the sides forward .
For dark hair baby powder with water and spray the hair , make the hair compact or you going to lose tracking , professionally I do use hair net in skin color the one used for under a wig since scalp hair are not needed in my case . Facial hair with baby powder and eyebrows . Keep the eyes closed as it easier to open them later with software than scanning open eyes that can’t be closed that easier .
Right now the Andrpid app offers 2000 frames for phones with 6GB RAM , I did not tested yet on Tablet but I would not recommend to use mobile apps if you looking for quality , it will take forever to fuse the point cloud … not really my thing to do unless it is a head at max.
that is …
NOTE: Do not pair the DATT to your phone other than via the app , do not operate the App before you see clear the DATT is Connected or it will result with Runtime Error on some devices . You need Connect your DATT before you can operate the APPs buttons .
Android APP to use with Revo Scan , including POP, POP2 and MINI also great for 360 degree Photography and Photogrammetry.
1st attempt with Mini, damn this thing is good !!
Had to recalibrate first as the accuracy test was giving around 1.5000 but got it down to 0.0300 after calibration.
Very impressed with the results considering the price of this scanner.
I’m finding your tests very interesting. I only have a Pop v1 to play with, so I decided to do some quick and dirty scans, because you couldn’t get your elephant to even read. The cow was a Holstein, so I used spray shampoo to dull out the black patches all over it!
Everyone says how much better the Pop 2 is, but I have to work with what I have!
The rhino is a standard polythene toy mid grey/brown 140mm long 70 mm high. The cow is similar. I use it mostly for scanning clay sculptures. This Archeopterix head is at the lower size end, about 30mm long. I had to do quite a bit of remodelling in zBrush to get it decent! (I didn’t have my Mini at this point)
I haven’t noticed any improvements in my Pop v1
@3D-looey you should since the point fusing algorithms changed, I can see it even on the animals surface you scanned , not that it is improving anything other than adding some grain surface .
The 30 mm is sadly the reaching point for a single volume .
When I purchased early POP1 , my only intension was to use it for scanning faces in general and it did the work I needed . The resolution was just fine as it was more for the shape /volume than fine details .
Don’t get obsessed, this type of scanning technology suffer a lot from grain effect on the surface , infrared in general is very picky on micro surface as even slightly micro reflection can cause noises shifting the points up and down .
Blue laser scanners like MINI dealing less with that issue .
I work also in Zbrush , and the best way is just to make retopology or remeshing the scan to get rid of the triangles so you can clean out all the noises on the surface much easier . Triangles are pest in post production .
