NAME
vig_optimize - Optimise photometric parameters
SYNOPSIS
vig_optimize [options] -o output.pto input.pto
DESCRIPTION
Photometric calculation can be performed on the command-line with the vig_optimize tool.
This functionally is configured via 'v' variable lines in the .pto project file in a
similar way to the autooptimiser tool:
The camera response curve is simplified using the EMoR sensor model which reduces the
variation to five numbers, these are the Ra, Rb, Rc, Rd & Re image (i) parameters (the
default values of 0.0 are equivalent to an 'average' generic sensor).
The vignetting model is represented by a polynomial with four parameters: Va (this is
always 1.0 and doesn't need to be optimised) and Vb, Vc & Vd (which default to 0.0 -
equivalent to no vignetting). The vignetting centre can also be different from the
geometrical centre, this is specified by Vx & Vy (both default to 0.0).
Exposure (EV) is represented by a single value Ev (defaults 0.0, equivalent to no-change).
The white balance is represented by multipliers for the red and blue channels Er and Eb
(the defaults of 1.0 are equivalent to no-change).
A typical 'v' variable line configuration would look like this, i.e. optimise camera
response curve and vignetting for image 0 and exposure for images 1, 2, 3 and 4:
v Ra0 Rb0 Rc0 Rd0 Re0 Vb0 Vc0 Vd0
v Ev1 Ev2 Ev3 Ev4
(vignetting centre and white balance are left unchanged)
