Hello everybody,

I would like to automatically transform my aerial images to orthoimages. I 
have never use OTB before. I have several aerial photos, their internal 
(camera calibration) and external orientation  (omega, phi, kappa, X, Y, Z) 
parameters and accurate DEM. 

I read documentation of OrthoRectification module and I have one question - 
is there any way to include orientations parameters in process of 
orthorectification? 

I mean... right now I have just raw aerial images without any projections 
in their metadata and DEM with precisely defined projection. If I 
understand everything correctly I should first rectify my aerial images. 
Simply assigning projection is not a good solution, because of rotation 
angels etc. I need something like affine transformation. Only after 
transformation (when photo and dem coincide) I can use OTB 
OrthoRectification module to convert from central to orthogonal projection 
and remove tilt and relief distortions. Am I right?

Everything would be much easier (and in one step) if only I could include 
orientation parameters in orthorectification process. Is there any way to 
do this in OTB?

Thank you in advance for your help and suggestions.
