NAME
pto_var: change image variables inside Hugin .pto project files
SYNOPSIS
pto_var [options] −−opt|−−link|−−unlink|−−set "image variables list input.pto
DESCRIPTION
pto_var is a command line tool, suitable for inclusion in shell scripts, and allows the change of image variables inside a Hugin .pto project file. Optimisation variables can be set, altered, linked and unlinked, The following image variables are allowed:
position: y, p, r, TrX, TrY, TrZ
lens parameters: v, a, b, c, d, e, g, t
photometric parameters: EeV, Er, Eb, Vb, Vc, Vd, Vx, Vy, Ra, Rb, Rc, Rd, Re (Vignetting and response parameter will treated as group.)
The image numbers start with zero. If the number is missing this applies to the variables of all images (In this case a special treatment applies to the position of the anchor image). An exclamation mark before the variable will remove the variable from the list of variables to optimised.
OPTIONS
−o|−−output = file.pto
Output Hugin PTO file. Default: <filename>_var.pto
−h|−−help
Shows help
−−opt varlist
Change optimizer variables
−−modify−opt
Modify the existing optimizer variables
(without pto_var will start with an
empty variables set)
Examples:
−−opt y,p,r Optimize yaw, pitch and roll of all images
(special treatment for anchor image applies)
−−opt v0,b2 Optimize hfov of image 0 and barrel distortion
of image 2
−−opt v,!v0 Optimize field of view for all images except
for the first image
−−modify−opt −−opt !v will not optimize field of view.
−−opt !a,!b,!c Don't optimise distortion (works only with
switch −−modify−opt together)
−−link varlist
Example:
−−link v3 Link hfov of image 3
−−link a1,b1,c1 Link distortions parameter for image 1
−−unlink varlist
Examples:
−−unlink v5 Unlink hfov for image 5
−−unlink a2,b2,c2 Unlink distortions parameters for image 2
−−set varlist
Examples:
−−set y0=0,r0=0,p0=0 Resets position of image 0
−−set Vx4=−10,Vy4=10 Sets vignetting offset for image 4
−−set v=20 Sets the field of view to 20 for all images
−−set y=val+20 Increase yaw by 20 deg for all images
−−set v=val*1.1 Increase fov by 10 % for all images
−−set y=i*20 Set yaw to 0, 20, 40, ...
−−set−from−file filename
Sets variables to new values
It reads the varlist from a file
