Re: Optoma ML750e

MicrO, can you show a comparison, FullHD vs lower res? Just curious :-)

(Was looking a bit on the Aaxa lineup but the Optoma was the easiest to get for me)

Optoma ML750e

My old Acer P1265 is about to give up after only 10 years!!

Bought (tiny!!!) Optoma ML750e and it seems to work nicely.

First test. 5 scans in stereo mode. 2x IS DMK 23UX236 with Computar 12mm.

Re: Control Stick

Mading, I use 120mm scale "inside corner". I turn the panels until cameras "see the same" - until RMS is equal. This case 0,07-0,08-ish on both. I tried the setting "Compensate angle between panels" It doesn't seem to affect RMS much but the scans aligned horribly. :?: Projector and cameras. Not eve...

Control Stick

Control Stick for a fighter aircraft. Which one? Sprayed with cyclododecane. Surface not perfect but the need for no cleaning of spray after makes it ok anyway. Number of scans is more than I wished for. Stereo mode, Manual turntable (I think I like this best. "IKEA Snudda" sprayed with matte black....

Re: Calibration Boards

A few mm offset in the left pattern? Is compensated for in the settings?

Will try to understand more this afternoon (while watching football, Sweden vs Switzerland!).
I have a couple of ball-heads for photography and am thinking about to use them for my camereas for a really
flexible setup.

Re: Calibration Boards

Mading,

What happens if you turn the panel just a little clockwise?
Looks like that panel picture #2 is the camera with higher RMS Error. Correct?

Re: Calibration Boards

Quick test today with homemade panel. Milled angles, 3mm glass and just office paper in the laser printer. I enlarged the 3 circles a bit and this acually decreased the RMS Error to the 0,28-range (from 0,33-0,35) 100mm scale. Then I tried to decrease distance a bit and the error increases with shor...
