Hi
Let's see in this topic , how deep we can go to a depth of less than a millimeter.

A challenge : macro scanning
Re: A challenge : macro scanning
I have started by using david laser scanner to go deep.
However it was not enough.

And the last one was a 1 mm needle.
But seems not enough yet.

Re: A challenge : macro scanning
Hi Narmella!
Good to see you are still active.
What is the average scannin time of one of these macro scan?
Would you mind to show the scans after alignment and before fusion?
How can you focus the projector on such a small area?
So many questions.. The quality of the pictures asks for them!

Re: A challenge : macro scanning
Hi , me too .
Unfortunately i haven't more pictures for them ( was a few years ago) ; except this one . (I got it from hunka tibor)
. .
This challenge consist of a few parameters:
- The light : using shorter wave will give us better results. Seems blue is good.
- playing with concave and convax lenses to have a good calibration using 15 mm and lower size of pannels.
- the quality of live view and its dimension.
And more.
Hope to see good results here.

Re: A challenge : macro scanning
I scanned a small swiss coin (19.12 mm diameter).
With a standard LG PF50, a couple of 12 mm lenses, my Daheng cameras and RangeVision scanner.
24 scans, alignment automatic (apart from getting the two half together).
coin scanned flat over the turntable
This can be improved significantly moving the lens of the projector to focus at shorter distance.
that's for another test.

Re: A challenge : macro scanning
Your "Let's Scan" app was very promising. I would have liked to see that developed and refined to a commercial level product. Perhaps a little more automated. I remember that the results I got with it, even the reduced version, were excellent.

Hope to try smaller one .

Hello micr0.
Your sentences have been ; are ; will be promising.
Thank you
Call you soon.
Re: A challenge : macro scanning
I once tried installing let's scan, without investing enough time to get a result. The idea was great, but instead I invested time and € in a stereo setup for HP3D.
In my opinion there are now more robust and productive sw for DIY scanning than david-HP3D. And cheaper.
Looking forward to see the recent updates of your software!
