Re: Issues with aligning scans

Did you made a custom flange for the lens? If so did you manually calculated the required flange length?

Re: Issues with aligning scans

This is my calibration result :D : rms_01.jpg And so it looks after scanning: rms_02.jpgrms_03.jpg Thanks for sharing your calibration data OBNRM! I could never get an RMS value below 0.65 (usually 0.85-1.15) - but there weren’t any such serious “inconsistencies”. P.S. I don’t know yet which way to...

Re: Some of my scans

Interesting both old and newer cameras have similar resolution right?

Re: Noob question on SLS

Hi Micro,

I contacted the seller but they said that this projector is out of stock. They recommended another projector that also uses square pixels and said that the autofocus feature in it can be disabled.

Re: Issues with aligning scans

From calibration, I get around 0.2 RMS error. I could never get an RMS value below 0.65 (usually 0.85-1.15) - but there weren’t any such serious “inconsistencies”. P.S. I don’t know yet which way to go to fix your problem. P.P.S. Usually, after calibration, I scan the calibration table and see how ...

Issues with aligning scans

Hi, I've been trying to do some scans of simple objects but I'm failing to make the scans aligned. My setup is a custom setup. LED printer + 5 MP vison camera + 12mm c mount lens The calibration panel is also custom made. The angle between the calibration panels are very close 90 degrees From calibr...

Re: Noob question on SLS

.jpg can be a very destructive compression scheme depending on the level of compression. I don't really know anything about the other formats. I have been using Y800 with my IS cameras which I believe is a raw monochrome format. It seems to work very well, but I have no experience with the other fo...

Re: Noob question on SLS

I see, what about sharpness? From your coin scan, the pattern seemed to be very sharp even at close range. Well, in the range of depth of field, when projected onto the plane of a coin, which is quite perpendicular to the projector, everything will be fine. And when the calibration angle is in plac...

Re: Noob question on SLS

So my conclusion was to buy a projector which is similar to your brand. Despite the fact that my projector can focus at a very close distance from a flat object, the depth of field of the projection pattern at close range is also very limited (no more than 50 mm) I see, what about sharpness? From y...

Re: Noob question on SLS

Thank you for the well-explained answer I will also go for a fixed focus lens. Up to now, I have done the following, 1. To reduce the field of view of the projector I 3d printed an extension tube and moved the whole lens element forward which allowed me to have a smaller field of view to scan smalle...
