Pinhole camera model wiki
WebGeometric calibration uses a projective camera (pinhole) model of a camera. Real cameras do not follow this model. Distortion models describe the mathematical deviation of a camera from the pinhole model. Available Models Geometric calibration in Imatest currently supports two types of radial distortion model: polynomial and polynomial division.

WebJan 26, 2024 · The pinhole camera. To mathematically model the pinhole camera, we make the following assumptions: The Image plane, which is the film or medium that captures the light rays, is situated in front of the pinhole. However, In the real world, it is located behind the pinhole. This assumption makes it easier to model the projection as we don’t ...
