[hugin-ptx] Grid / Projection modification - customize

[Abrimaal]

Does Hugin allow grid (projection) modifications? Modifying an existing 
grid or creating a new one?

For architecture taken from very close distance (like a high building taken 
from the other side of a narrow street - often there is no other way)
I would like to configure a grid with 
| | | | vertical lines straight, parallel
= = horizontal lines parallel too
but switchable between equirectangular / mercator / cylindrical scale or 
better adjustable with a slider like in panini general. 

This projection will be useful for straightening architecture, below an 
example.
Where equirectangular / mercator are not suitable, because of curved 
horizontal lines.

*A* is the original photo 
*B *is after straightening the || vertical lines in the rectilinear 
projection. The upper part, the tower is too tall because of the grid that 
consists of identical squares
*C* is after rescaling, still not good. The lower part became too small.

I have images that include Pitch, Yaw, Roll metadata in Exif. When I

them manually. Is there any way to load those metadata, or what format
should the image have for Hugin recognize those parameters?


I'm not aware of a camera that includes y/p/r information, what
hardware do you use to generate these values? A pano bot or some
fancy GPS tracker mounted to the camera using the hot shoe?


More to the point, how is this information encoded into the EXIF data?
I'm pretty sure there's nothing in the standard.


Standard? I think all camera manufacturers add their own proprietary 
exif tags.


ExifTool comes to the rescue:



GPSImageDirection
GPSPitch
GPSRoll

At some point Geoff Mather provides a link to a tutorial he has written: 


which concludes with...

Other software likely to make use of GPSImageDirection, GPSPItch & GPSRoll
To date, April 2012,
  Joost has it on his list for PTGui.
  Thomas has it on his list for Pano2VR.
  Friedmann has it on his list for Geosetter.

... and the yaw info should be stored in the GPSImgDirection tag.

At least Olympus and Pentax cameras with built-in electronic level write
the pitch/roll information in the "maker notes" part of EXIF data. Yaw
detection would need a built-in compass like in Pentax K-3II and K-1.
