How to scan small objects with high detail (Page 1 of 2)

thats why I just refocused the camera to proper Macro for my objects to have crisp focus at center of turntable. so as not to change magnification and dimensions of scanned object in file.

also there are replacement lenses for the Pi cam on ebay cheap for other uses of the camera. and youtubes of how to swap them etc.

the Atlas scanner as shipped just dont have crisp Macro ability until focused properly also laser lines are too fat for anything but fuzzy surface details on objects with small corner areas. I have not yet gotten my patience back to finalize the focusable lasers swapped in with new mounts etc nor messed with the new photo tent and light meter. the camera focus nearly ended with me bashing the scanner to bits between that tedious work and its bad power supply issues frustrating me. lol
and the non working WIFI connection must be hard wired instead. the settings tweaking is a whole other challenge too. guess I'm getting short tempered in my old age. I used to do great on tiny mind blowing tedious modeling etc and puzzles.
maybe when other projects get finished around the house I'll come back to 'THE Scanner' but for now 3D printing stuff has to wait (or as my wife calls them "playing with aggravating Toys") I am thinking she may be right.

About how big are the Warhammer models?  Can you post a picture of what you're currently getting?

I'm sure what we are trying to do is achievable with the Atlas Scanner if modified/tweaked in a few areas. then maybe upgrade kit at a small price increase and clinch the low budget 3D scanner market for small modelers at least. I am sure the war gaming metal casting industry wont like it though hehe. but the Gamers will love it when they can drop the hazards of lead/pewter casting for 3D printing low hazard methods at same or cheaper cost on rare new objects custom made.

Thanks a lot for helping with this Uriah! I think its a great opportunity to expand the scanners sales and appeal to R&D, architecture modeling, and other miniature modeling craftsman and grow your product marketing/future. there are low cost lasers with focus that have a 12mm barrel instead of the 9mm current ones so new mounts are also needed plus those lasers have much shorter wires that need spliced to old wires or lengthened. also there are options after market for the Pi camera so they should also be available from factory with preset Macro focus distance or adjustable much easier than the current way. or maybe change focal length for deeper field of view depending on size of target to be scanned.

I think its great the designer/maker of the Scanner gets involved in upgrades to meet customer needs as they arise. this is rare these days with the fast paced China production route most manufacturers use. you rock!

Here are my adapted laser holders, designed for the 12mm focus-able line lasers.  The knurled ring at the back is fixed on the body of the lasers, and adjusts the vertical alignment of the laser line.

So you first adjust the focus by adjusting the front ring on the laser.  Once that's in focus, you use the back ring to adjust the vertical alignment.

For those interested in changing to 12mm lasers, I'm including the STL files.   

BTW, the model doesn't have any extra clearance built in, as I printed these things on my Form 1+, and the dimensional accuracy is such that I don't need to account for filament expansion or anything like that.  So you may have to do some sanding.

Pirvan, can you post a link to the lasers you are using? What about the possibility of using something like this? http://www.ipevo.com/prods/Ziggi-HD_Plu … nt_Camera, 8MP. I have one and the quality is quite good, and it has adjustable focus (including macro) and works over USB etc. Exposure can be controlled as well. I might try it once I get my rig working if I find the results poor.

There is also something like this:

http://www.e-consystems.com/UltraHD-USB-Camera.asp. 13 MP board-level camera, works over USB 3.0...I know the pi doesn't have usb 3.0 ports but it could be substituted with something else?

maybe if the new Pi3 can be used on the Atlas.

main thing is keep laser and ambient light frequency/color so camera and software can see them well enough to gain finer details

The files you need are referenced at the bottom of the description.

Thanks a lot.  The lasers just arrived and I'm printing the holders now.

Yes, I'm still working in this area but I haven't had a chance to devote a lot of time to it yet.  I first tried adjusting the focal distance of the 8MP camera to all close as possible and then using a shorter frame in order to increase the relative object size on the sensor.  This seems to help, but the results are still not what I would like.  The main problem I'm facing is accurately and consistently choosing the center of the laser line with these very small objects.  I plan on experimenting with another laser, the Pi NOIR camera, and to see what software changes can be made that will help.

Any movement on this yet?
