two camera process
« on: July 02, 2018, 09:58:16 AM »
We are using two syncronized cameras simultaneously and process multiband mosaics. Overlaps are over 80 %, so they should be OK. We also use separate calibration files for cameras.  Alignment error is user interface is submeters but slave camera orientation is not correct for some pictures. We have also swapped slave / main cameras. Result is the same, it is always slave camera error. So both cameras are for sure OK, problem is in the algorithm.

Perhaps 90 % are OK but the the rest are misaligned several meters. Any idea for correction? Is it useful to set slave came offset ? If so, where to get offsets? We have processed these different cameras also in different processes so we could take offset differences if orientations could be seen somewhere?

We also exported omega, phi, kappa but there is only very small (e.g. 0.01 degrees) between two cameras. Difference should be bigger to produce e.g. 2 meters error. It seems that exported values are not really true orientations used in mosaicking phase???

Hello mapping_1,

Can you please specify, how you are checking the alignment results and slave offset estimation? Do you enable Fit Location in the Slave Offset tab?
