Do all my photos have to be rotated the same way for auto fiducial collection to run properly?
Yes and No. The auto fiducial collection will run successfully for any combination of orientations. However, the calibration edge has to be set manually. There is no automatic way to do this, since the digital image can be in any orientation. So, you have two options: a) run the automatic fiducial collection on the raw images, and then manually change the calibration edge for the affected photos, or, b) rotate the images to a common orientation (using our batch rotate function) before running the auto fiducial collection. Then the calibration edge will not need to be adjusted. I would suggest the first option, since it is usually easiest to work with photos if they are all scanned with left to right overlap, with the up axis of the digital images all pointing the same way (i.e all North-up, or all East-Up, or all 45-degrees-Up.) That makes stereo viewing possible, makes epipolar generation easier, and makes the GCP collection more intuitive.
