Can barrel distortion be corrected?
Lens barrel distortion can be corrected in post-processing using software tools such as Adobe Lightroom, Photoshop, or other image editing software.
Most image editing software includes a lens correction tool that can automatically correct for distortion based on the lens profile.How do you remove barrel distortion?
As distortion is caused by the effects of perspective on the lens, the only way to correct for barrel lens distortion in-camera is to use a special "tilt and shift" lens, which is designed for architectural purposes.
However, these lenses are costly, and only really make sense if you specialize in this field.What is the equation for barrel distortion?
(1.17) u d = u n 1 + K 1 r 2 + K 2 r 4 , v d = v n 1 + K 1 r 2 + K 2 r 4 , Barrel distortion is typically modeled with negative K1 value, whereas pincushion distortion has positive K1 value.
The radial distortion correction (RADIC) model attempts to register images in a distortion-free coordinate system using a planar-to-spherical transformation, so the registered image is isotropic under a perfect registration, and places the registered image in an isotropic coordinate system (Fig.
