Since you shot down from above I suspect that you get perspective
distortion, too. You can correct that but you will have to allow
optimization of Pitch and Roll for *all* images (even the anchor
image). In PTGui you must switch to "Advanced" display on Optimizer
tab to do that.
More about perspective correction on

BTW.: It would be easier to help if you provided an example image...
