Expand description

Brown-Conrady radial and tangential lens distortion parameters.

These describe the distortion of a physical lens. Negative radial coefficients model barrel distortion; positive values model pincushion.

Fields§

§k1: f64

Radial distortion coefficient k1.

§k2: f64

Radial distortion coefficient k2.

§k3: f64

Radial distortion coefficient k3.

§p1: f64

Tangential distortion coefficient p1.

§p2: f64

Tangential distortion coefficient p2.

§cx: f64

Principal point x (normalised, typically 0.5).

§cy: f64

Principal point y (normalised, typically 0.5).

§fx: f64

Focal length x (normalised, typically ~1.0 for a 90° FOV).

§fy: f64

Focal length y (normalised).

Implementations§

Source §

impl LensDistortionParams

Source

pub fn barrel() -> Self

Create parameters modelling mild barrel distortion (typical wide-angle lens).

Source

pub fn pincushion() -> Self

Create parameters modelling mild pincushion distortion (typical telephoto).

Source

pub fn undistort_point(&self, x_nd: f64, y_nd: f64) -> (f64, f64)

Map a distorted normalised pixel coordinate to an undistorted one.

The coordinate is normalised so that (0, 0) = top-left and (1, 1) = bottom-right.
