Chapter 3: Camera Models.

Chapter 3 of the book "Foundations and Trends in Computer Graphics and Vision," by P. Sturm and colleagues is presented. It explores the various computational camera models. It says that pinhole camera model assumes camera rays' passage to a single point called the optical center and that the relationship between image point position and camera ray direction is linear and can be expressed in a calibration matrix. It tackles other models including global and local, two-plane, and discrete models.
