Camera geometry fundamentals
Abstract
This chapter is concerned with the geometry that describes how objects in the 3D world are captured as 2D pixels. These descriptions are mathematical models that define a mapping between 3D objects (generally points) in the world and 2D objects in a plane that represents an image. The final aim is to be able to obtain 3D information from the 2D position of pixels. The techniques of 3D analysis such as reconstruction or photogrammetry are studied in computer vision. This chapter does not cover computer vision techniques, but gives an introduction to the fundamental concepts of the geometry of computer vision. It aims to complement the concepts in Chapter 1 by increasing the background knowledge ...
