<H2>DESCRIPTION</H2>
|
||||
|
||||
Apply radial or flatfield vignetting correction as well as geometrical radial
|
||||
distortion and transversal chromatic aberration correction.
|
||||
<P>
|
||||
fulla can be used to batch correct a large number of files. Radial distortion coefficients can be read from a PTLens database (only database version 4.2 is supported).
|
||||
<P>
|
||||
Vignetting correction is done the same way as described in the nona script file documentation.
|
||||
Vignetting correction can be done based on a flatfield or a radial scaling.
|
||||
<P>
|
||||
Vignetting correction by flatfield division:
|
||||
<BR> I = I / c, c = flatfield / mean(flatfield)
|
||||
<P>
|
||||
Radial vignetting correction:
|
||||
<BR> I = I / c, c = a + b*r^2 + c*r^4 + d*r^6
|
||||
<P>
|
||||
Correct vignetting by addition, rather than by division:
|
||||
<BR> I = I + c
|
||||
<P>
|
||||
<P>
|
||||
<P>
|
||||
The radial correction is identical to the one implemented by panotools:
|
||||
<P>
|
||||
r_new = a*r^4 + b*r^3 + c*r^2 + d*r [1]
|
||||
<P>
|
||||
Since transversal chromatic aberrations (TCA) leads to differently scaled objects in the
|
||||
red, green and blue channel, it can be corrected by scaling the red and blue channel
|
||||
so that they match the green channel. Most applications, like Photoshop or Picture Window Pro
|
||||
offer TCA correction by linear scaling. This is equal to varying the d parameter in equation [1].
|
||||
<P>
|
||||
See <A HREF="http://hugin.sf.net/tutorials/tca">http://hugin.sf.net/tutorials/tca</A> for a method to determine these parameters.

<H2>OPTIONS</H2>
|
||||
|
||||
<DL COMPACT>
|
||||
<DT>-o<DD>
|
||||
Specify the output filename. If more than one input image is given, this string will be used as suffix (default: _corr)
|
||||
<DT>-g<DD>
|
||||
Radial distortion coefficient for all channels, (a, b, c, d).
|
||||
By default no correction is done.
|
||||
<DT>-b<DD>
|
||||
Radial distortion coefficients for blue channel, (a, b, c, d).
|
||||
this is applied after the global distortion correction(supplied by -g).
|
||||
<DT>-r<DD>
|
||||
Radial distortion coefficients for red channel, (a, b, c, d).
|
||||
this is applied after the global distortion correction(supplied by -g).
|
||||
<DT>-f<DD>
|
||||
Filename of the flatfield image. Enables vignetting correction by flatfield
|
||||
division
|
||||
<DT>-c<DD>
|
||||
radial vignetting correction by division:
|
||||
<DT>-a<DD>
|
||||
Correct vignetting by addition, rather than by division
|
||||
I = I + c
|
||||
<DT>-p<DD>
|
||||
Try to read radial distortion coefficients (usually supplied
|
||||
using -g) from the PTLens database. The environment variable PTLENS_PROFILE
|
||||
should point to the profile.txt file. Since newer version of the PTLens database
|
||||
are incompatible with fulla, download the PTLens database from the hugin sourceforge
|
||||
website instead: <A HREF="http://www.sf.net/projects/hugin">http://www.sf.net/projects/hugin</A>
|
||||
<DT>-m<DD>
|
||||
Camera manufacturer, for PTLens database query. EXIF data inside jpg files is read, if this
|
||||
option is not given
|
||||
<DT>-n<DD>
|
||||
Camera name, for PTLens database query. EXIF data inside jpg files is read, if this
|
||||
option is not given.
|
||||
<DT>-l<DD>
|
||||
Lens name, for PTLens database query. If not specified, a list of
|
||||
possible lenses is displayed
|
||||
<DT>-t<DD>
|
||||
Number of threads that should be used during processing
|
||||
<DT>-v<DD>
|
||||
Verbose execution

<H2>BUGS</H2>
|

|

No bugs known, if you find any, please send a bug report to me. I will try to
|
||||
fix it.
