Hi,
You should not modify the calcuations unless you know exactly what you
are doing. To handle ortho-ready images in OTB properly, you can use
extended filenames. Please read :
http://orfeo-toolbox.org/packages/nightly/latest/SoftwareGuide/SoftwareGuidech6.html#x26-900006.10
If you add the skip_carto option on both your images, you should be able
to stereo-rectify them without any code change.
Regards,
Julien

I tried stereorectificationFieldSource with ortho-ready images and I
was unable to perform the epipolar rectification. I checked the code
and found out some sensor specific calculations (such as sensor to
ground and ground to other image transformations). I rewrote those
transformation so that it is possible to transform left image to
ground and to right image. When I do the rectification, instead of
epipolar lines that are parallel to +x axis, I got epipolar lines that
have certain angle. Any ideas what is wrong with my methodology or any
ideas to performs epipolar rectification on ortho-ready images would
be very much appreciated. I know the original code is for sensor
geometry but I dont see any reason not to use the same technique for
ortho-ready images.
All the best
Emre
