Remove radial/tangential distortion from a point on the image plane.

Remove radial/tangential distortion from a point on the image plane.

Usage

radial_distort(xy, k, max_iterations = 5, tolerance = 1e-09)

Arguments

xy

Numeric vector of length two, or a two-column matrix of distorted points expressed in normalised image coordinates (after subtracting the principal point and dividing by the focal lengths).

k

Distortion coefficients. Supports numeric vectors, named vectors containing entries such as `k1`, `k2`, `k3`, `p1`, `p2`, or lists with `radial` and `tangential` components. Missing coefficients are treated as zero.

max_iterations

Maximum number of fixed-point iterations used when inverting the distortion model. Defaults to `5`.

tolerance

Convergence tolerance for the iterative solve. Defaults to `1e-9`.

Value

Distortion-corrected point(s) with the same shape as `xy`.
