RangeVision DIY - my rig

[mading]

Hi there,
I start my post about the Rangevision DIY with a cheap and simple solution for stereo system with cameras with fixed angle, that can be used also in Flexscan or HP.
It's an Arca Style clamp, you can find in Aliexpress:

I printed a 2D view from the Daheng step file in common paper, and taped it to the clamps as a hole guide.
A few holes with a Pilar drill, and common M3*12 screws.

I had several issue with (more expensive) Arca style pan-head: very difficult to block at a desidered angle.
Good for taking pictures, not suitable for a rigid scanning rig.

Hopefully in the next week I will share the rest of the rig (as soon as I finish it)

I've been looking at those but always thought they were too expensive to give it a try. I haven't ordered anything from Aliexpress before. Might have to try Aliexpress for that price. Looking forward to what you come up with. Did you also buy the rail from Aliexpress as well?

Hi there, I think I bought the Arca pan head branded "Haoge" and rail at an ebay shop in 2018 or before:

Items are still listed, even though the shop looks empty.
I DON'T suggest their pan-head for scanning.

I think any decent rail will do its job. Mine is 40 cm, the longest I could find. That's probably not enough for large FOV.

If you look at the recommended distances, then for the largest Rangevision DIY table (zone 1), then 40 cm of rail is more than enough (in any case, if the object is too large, you will need to scan in parts and, preferably, using markers)

Recommended distances between cameras and distance to tables

Don't laugh.
Only now I realized I always looked at this graph upside down...
That's good to know. I am not going to scan cars for now.

Today I tried scanning a very dark (and bit reflective) ebony chinrest with Rangevision.
With long exposition time and double exposure it's possible to get most of the data from the object.

Automatic turntable works wonderfully.
Coming from HP3D+AutoIT+Arduino makes you appreciate these things even more.
Alignment is made during the scan, that makes all the process automatic.

Only a final registration is needed, but it doesn't take not a long time (a few minutes).

Projector: the low-brightness LG PF50Ks. moving to the LG PF1500 could speed up.

I tried the blue light option with filters, but did not have the time to properly set-up the thing.
