PanoTools NG:
Remapping Help needed (Naive Developer)

Hi all,
I am new to this group. I am
working on image stream stitcher. Here no of cameras will be there. There will
be overlap in camera output. Using this overlap the designed system will stitch
images.
I am new to this image stitching
stuff. After going though some internet sites & few reference papers, I got
some useful open source projects like PanoTools, Autopano-SIFT, Hugin, Enblend,
PanoToolsNG etc.
PanoTools & Hugin are good
one to start. As I have to do image stream stitching in real time Autopano-SIFT
can be used, as it is one time job.
But the real problem is how
remapping is done using control points. For that also I had found that Lev-Mar
algorithm is used along with control points to find optimal values for some
parameters like lens correction coefficients (a,b,c), lens offset (d,e), lens
shear (g,t) plus yaw, pitch, roll (y, p, r) plus FOV.
As far as my knowledge about
optimization and remapping is concerned, I feel that optimization &
remapping are closely related to each other. I know lens correction equation http://www.all-in-one.ee/~dersch/barrel/barrel.html.
But I am not able to get why
& how yaw, pitch, roll is used in remapping. If any can send some links of
basic details or reference papers. I know, it is very simple but I am not able
to link it with other details.
Links to other sample codes or
easy to understand projects will be great help.
Thanking you.
Yours truly,
Pritam Prakash Shete.
