12 Photometric calculation can be performed on the command-line with the
13 vig_optimize tool. This functionally is configured via 'v' variable
14 lines in the .pto project file in a similar way to the autooptimiser
15 tool:
16
17 The camera response curve is simplified using the EMoR sensor model
18 which reduces the variation to five numbers, these are the Ra, Rb, Rc,
19 Rd & Re image (i) parameters (the default values of 0.0 are equivalent
20 to an 'average' generic sensor).
21
22 The vignetting model is represented by a polynomial with four
23 parameters: Va (this is always 1.0 and doesn't need to be optimised)
24 and Vb, Vc & Vd (which default to 0.0 - equivalent to no vignetting).
25 The vignetting centre can also be different from the geometrical
26 centre, this is specified by Vx & Vy (both default to 0.0).
27
28 Exposure (EV) is represented by a single value Ev (defaults 0.0,
29 equivalent to no-change).
30
31 The white balance is represented by multipliers for the red and blue
32 channels Er and Eb (the defaults of 1.0 are equivalent to no-change).
33
34 A typical 'v' variable line configuration would look like this, i.e.
35 optimise camera response curve and vignetting for image 0 and exposure
36 for images 1, 2, 3 and 4:
37
38 v Ra0 Rb0 Rc0 Rd0 Re0 Vb0 Vc0 Vd0
39 v Ev1 Ev2 Ev3 Ev4
40
41 (vignetting centre and white balance are left unchanged)
