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
