/*
|
||||
Original Lens Distortion Algorithm from SSontech
|
||||
http://www.ssontech.com/content/lensalg.htm
|
||||
|
||||
If (u,v) are the coordinates of a feature in the undistorted perfect
|
||||
image plane, then (u', v') are the coordinates of the feature on the
|
||||
distorted image plate, ie the scanned or captured image from the
|
||||
camera. The distortion occurs radially away from the image center,
|
||||
with correction for the image aspect ratio (image_aspect = physical
|
||||
image width/height), as follows:
|
||||
|
||||
r2 = image_aspect*image_aspect*u*u + v*v
|
||||
f = 1 + r2*(k + kcube*sqrt(r2))
|
||||
u' = f*u
|
||||
v' = f*v
|
||||
|
||||
The constant k is the distortion coefficient that appears on the lens
|
||||
panel and through Sizzle. It is generally a small positive or negative
|
||||
number under 1%. The constant kcube is the cubic distortion value found
|
||||
on the image preprocessor's lens panel: it can be used to undistort or
|
||||
redistort images, but it does not affect or get computed by the solver.
|
||||
When no cubic distortion is needed, neither is the square root, saving
|
||||
time.
|
||||
|
||||
Chromatic Aberration example,
|
||||
using red distord channel with green and blue undistord channel:
|
||||
|
||||
k = vec3(-0.15, 0.0, 0.0);
|
||||
kcube = vec3(0.15, 0.0, 0.0);
