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

pinhole camera model

The idealized camera model of light passing through a single point onto an image plane.

The pinhole camera model idealizes a camera as light rays passing through a single point (the center of projection) onto a flat image plane, with no lens at all. Every real lens camera is modeled as an approximate pinhole camera plus a distortion correction, since a real lens introduces deviations the pure pinhole model does not predict.

Examples

  • Every real camera lens is modeled as an idealized pinhole camera plus a distortion correction layered on top of it.
