Free public beta until December 4, 2026: every course is open, no card needed. After that, the first chapter of each course stays free and full access is a one-time $39 ($19 for up to 100 founding members chosen for helpful feedback). Your progress is kept. How the beta works

camera calibration

Estimating a camera's intrinsic and extrinsic parameters from known point correspondences.

Camera calibration recovers a camera's intrinsic and extrinsic parameters, and its distortion coefficients, by observing a target whose true 3D geometry is known (commonly a checkerboard) at several poses and solving for the parameters that best explain the observed image points.

Examples

  • Photographing a checkerboard from a dozen different angles and distances gives enough correspondences to solve for both the intrinsic matrix and the lens distortion coefficients at once.
