NAME
Panotools::Script::Line::Image - Panotools input image
SYNOPSIS
A single input image is described by an 'i' line
DESCRIPTION
Basically the same format as an 'o' line.
w1000
h500 nona requires the width and height of input images wheras PTStitcher/mender don't
f0 projection format,
0 - rectilinear (normal lenses)
1 - Panoramic (Scanning cameras like Noblex)
2 - Circular fisheye
3 - full-frame fisheye
4 - PSphere, equirectangular
v82 horizontal field of view of image (required)
y0 yaw angle (required)
p43 pitch angle (required)
r0 roll angle (required)
a,b,c lens correction coefficients (optional)
(see http://www.fh-furtwangen.de/~dersch/barrel/barrel.html)
d,e initial lens offset in pixels(defaults d0 e0, optional).
Used to correct for offset from center of image
d - horizontal offset,
e - vertical offset
g,t initial lens shear. Use to remove slight misalignment
of the line scanner relative to the film transport
g - horizontal shear
t - vertical shear
K0a, K0b linear color/grayvalue correction coefficients for each channel
K1a, K1b (for grayscale images Only K0a, K0b is used):
K2a, K2b i_red = K0a * i_red + K0b
i_green = K1a * i_green + K1b
i_blue = K2a * i_blue + K2b
This correction is applied after the flatfield flatfield correction.
Vm vignetting correction mode (default 0):
0: no vignetting correction
1: radial vignetting correction (see j,k,l,o options)
2: flatfield vignetting correction (see p option)
4: proportional correction: i_new = i / corr.
This mode is recommended for use with linear data.
If the input data is gamma corrected, try adding g2.2
to the m line.
default is additive correction: i_new = i + corr
Both radial and flatfield correction can be combined with the
proportional correction by adding 4.
Examples: i1 - radial polynomial correction by addition.
The coefficients j,k,l,o must be specified.
i5 - radial polynomial correction by division.
The coefficients j,k,l,o must be specified.
i6 - flatfield correction by division.
The flatfield image should be specified with the p option
Va,Vb,Vc,Vd vignetting correction coefficients. (defaults: 0,0,0,0)
( 0, 2, 4, 6 order polynomial coefficients):
corr = ( i + j*r^2 + k*r^4 + l*r^6), where r is the distance from the image center
The corrected pixel value is calculated with: i_new = i_old + corr
if additive correction is used (default)
for proportional correction (h5): i_new = i_old / corr;
Vx,Vy radial vignetting correction offset in pixels (defaults q0 w0, optional).
Used to correct for offset from center of image
Vx - horizontal offset
Vy - vertical offset
Vf filename of flatfield image.
For additive correction the image will be used as it is.
In the case of correction by division, the flatfield will be divided by
its mean value.
S100,600,100,800 Selection(l,r,t,b), Only pixels inside the rectangle will be used for conversion.
Original image size is used for all image parameters
(e.g. field-of-view) refer to the original image.
Selection can be outside image dimension.
The selection will be circular for circular fisheye images, and
rectangular for all other projection formats
X10 World coordinates of camera position, only used for PTStereo
Y200 If the camera is aligned (yaw = pitch = roll = 0.0),
Z-13.5 X is coordinate to the right, Y vertically up and
-Z is forward viewing direction.
nName file name of the input image.
C100,600,100,800 Crop(l,r,t,b), Only pixels inside the rectangle will be used for conversion.
Cropped image size is used for all image parameters
(e.g. field-of-view) refer to the cropped part of the image.
i (the small letter). Morph-to-fit using control points.
