Re: First scans with lowbudget rig

Having to use specific cameras and the limit of 3mpix doesn't sound that great. I'm still interested in your results with the new software. ---- I just finished building my 420mm panels and just placed them on the ground with some tape. The first alignment gave me a RMS value of 0.097 and i'm still ...

Re: First scans with lowbudget rig

I've visited a local store and let them print a DIN A0 sheet for a big calibration table and will glue that to 19mm melamine-coated chipboard. The scale is ~420mm, let's see how that works out... Rangevision sounds interesting. You've said that they introduced a resolution limit for diy scanners. Is...

Re: First scans with lowbudget rig

I'd say it's not the distance which caused these high RMS values but rather the wider view onto the panel. If i barely fit the donuts into the view, then RMS drops. If i include the whole panel (and thus the donuts become smaller) RMS increases. So your conclusion to a) use panels which are big enou...

Re: First scans with lowbudget rig

My RMS value is more affected by the resolution of cameras (if you make a low resolution, then the result will be better on the same table) I also noticed that if the table is smaller than the area indicated in the center of the program screen, then the edges of the scan, even with a good RMS bend ...

Re: First scans with lowbudget rig

I received a scan with a total of 32 cuts and the quality is not satisfactory. The data received in 32 cuts is about 1.8 gigabytes. Another question is what is RMS above. And where do you get that data from? Everything is unfamiliar because there is no knowledge of the camera and scan. Regarding th...

Re: First scans with lowbudget rig

Half resolution (FullHD) - the table completely occupies the configuration area By coincidence i did it like shown in the second image. Lucky me i guess... I also haven't had issues with bend scans, however i'm using the calibration angle compensation (i got 90.3° with my plates). Here's another te...

Re: First scans with lowbudget rig

I forgot to mention the eyes, sorry for that. The eyes on the photogrammetry scan were edited in afterwards with Meshmixer. These are glossy and transparent and thus i couldn't scan them with either technique. Besides that both scans are completely ontouched and directly out of cam (or out of scanne...

Re: SLS on a budget - camera and lens choice

Just tried again. T6 works, T7 doesn't (too big). 1.5mm hex is also too big. Maybe the setscrew is some imperial size? Sadly i don't have smaller hex bits to try.

Re: SLS on a budget - camera and lens choice

The screw is either Hexagon or Torx. I think i used a T6 or T8 screwdriver. Using hex should also work.
