Some of my scans

Post by OBNRacerMan » 14 Aug 2019, 11:21

I became interested in 3D scanning a little more than six months ago. I have scanners of "different systems" - the first was Kinect for xBox360, then Ciclop laser appeared (which turned out to be nothing more than a toy).

I don’t bring scans from Ciclops, there is nothing to look at especially.

And then I, already realizing what each type of scanner can do, assembled a “normal” SLS scanner for myself, gradually improving it (improvement using cameras with better characteristics, adding a second camera, a turntable with a motorized drive for automatic circular scanning of small objects)

The part of the bike made up of more than 10 close-range scans (I forgot that the scanner was calibrated to a 30mm table :-) )

Nice work. Do you coat any of the objects you are scanning?

No, the scan was done "as is". I don’t have anything suitable for matting yet (and using ordinary chalk or other powdered products will require thorough cleaning after scanning - which I don’t want to do :-))
Here, for example, the coin looked like when scanning:

Trying to scan something big enough. I made 12 scans from one point (only rotated scanner horizontally and vertically on a tripod). I used my largest 110mm calibration chart.

And a little from a different angle ...

I spread the next scan of the "rodent" (I found an old inoperative mouse at home on the shelf) Gigabyte ECO600.
The main desire is to scan "as is" without matting - and the concomitant problem is the mouse is black and glossy.
I had to take shutter speeds from 1/16s to 1/4s (and a total of 25 scans were made).

So the object looked during the scan

After folding the pieces it turned out like this

I got 11 million triangles at the output ... if not for the “noisy” cameras, I think their number without any optimizations would be an order of magnitude smaller.
P.S. I did not regret it at all about the money spent on upgrading the computer for the amount of memory - 32GB - since, at most, about 14GB was "eaten" during the scan.

The calibration was according to the 50mm table, scanning in the "composite" mode - with both cameras (in the "advanced" mode "it would be visible" would be more, but the noise is simply indecent)

what do you mean as a turntable with a motorized drive for automatic circular scanning of small objects for david 5?

Hi. I sometimes use a motorized turntable left over from a previous Cyclops primitive laser scanner.
By changing the software in the original control board for this scanner, I got the option of “almost automatic” scanning (just after the end of the next scanning step I need to manually press “S” (I programmed this button for this function), after which the table rotates by a hard-coded number of degrees and a new scan occurs). Of course, I only use the table rotation function.
Unfortunately, due to the fact that I could not fully figure out the Deviare program, I had to use just such a method (and not completely automatic, as it would be with Deviare).

Information and a detailed description of how to connect a homemade turntable to the HP3Dscan 5.60 I found here

I run the mentioned turntable/deviare-concept. Works like a charm.

And I have some kind of problem with Deviare - he does not want to track the events of the program necessary for fully automatic operation. I don’t know what’s stopping him ... maybe an antivirus ... although there are no warnings.
