Questions about projected position of feature in final panorama

[王浩宇]

Hi everyone,

I am a PhD student working on the panorama stitching based on the hugin and PanoTools. Right now, I get stuck about how to determine the final position of extracted features in stitched panorama. I know there are roll, pitch and yaw that describe position if each image in pto files. However, it seems that I cannot use them to warp images directly and after I set up the output size of panorama to scale the original image, I just cannot locate those features I used for alignment. I also found the result of optimization function will give the errors information in pixel. And based on understanding, I believe those errors are calculated from the projected position of features in final panorama.Thus, I'd like to get access to those position information. Anyone can give me some suggestions about it? I do really appreciate any help form this group.

As Hugin works in 2D, I assume you are looking for some relationship
between points in the original image and points in the transformed image.
Have you looked at the 'pano_trafo' function?

Hello Terry Duell , 

Thanks for your responses. I just check the function ''pano_trafo'' carefully and find it just give what I want exactly. Thanks a lot for your help.
