problem with alignment

Postby bipbay » Tue Nov 11, 2014 2:34 pm

Guys , I'm having some problem while trying to align two scan togethr , tried a 100 times , they just won't go in together
the scan was just over laping the other , I've put some white dot on the scanned item to make it easlier to line up , stil no luck .
I try all the alignment tools david had but just can't line up right , I click on one dot and click on the other one I would like them to go together , then red line shows up , but it was going all over the place, or it will line up that one dot I marked but the other side of the scan will move also ......
Please hlep :( :( :( :( :(

use a bigger angle as I replied in your other post also you can see to much of around the calibration panel move closer or use bigger panel you only need to see the 6 circles and some of the dots not all the panel
something like this

as you can see I have a small gap at the top but with my new projector mount I have fixed that now but don't have a screen shot of that

ok for you I've done a quick calibration shot

try around 22° first my camera needs moved a little but it shows you how it should be,
also try to have more of an overlap of your scans may help until you get more used to the scanning proses, don't worry It took some time to get good scans for me to
I just kept changing settings and angles until I found best setup,
what camera and projector you using?

Evenness and squareness calibration surfaces is very important .... One of the good options - oracal whits print glue on the glass ...
