Definition

The camera has intrinsic parameters that represent the internal characteristics of the camera and extrinsic parameters that represent the position and orientation of the camera. When all of these intrinsic and extrinsic parameters have been determined, the camera is called a calibrated camera, and when these parameters are unknown, the camera is called an uncalibrated camera.

Theory

Assuming that the projection on the camera can be represented by a pinhole camera and there is no nonlinear distortion of the second order or higher, the projection from a 3D point X to a 2D image point x can be described by using a 3 × 4 matrix P:

$$\displaystyle \begin{aligned} \begin{array}{rcl} \mathbf{x} = \mathbf{P}\mathbf{X} \end{array} \end{aligned} $$
(1)

where an image point [x, y]⊤is represented by homogeneous...
