Enter an intrinsics matrix (K) and distortion coefficients, and see how a flat checkerboard target would actually appear through that lens — before you point a real camera at anything.

Distortion Coefficients
Negative k1 barrels the image outward, positive k1 pinches it inward. p1/p2 model an off-axis (decentered) lens.

This is a synthetic fronto-parallel checkerboard, projected through your K matrix and then warped by the Brown–Conrady distortion model (k1, k2, k3, p1, p2 — same order and convention as OpenCV's distCoeffs). Straight world lines that curve here will curve the same way in real footage from this lens.
