single camera model¶
In the above image, you can see that this camera model consists of a linear pinhole projection model followed by a nonlinear distortion model. The pinhole model is specified completely by the 3x4 matrix M (or, equivalently, the 3x3 intrinsic matrix P, the 3x3 ortho-normal rotation matrix Q, and the translation vector t). The nonlinear distortion model is specified completely by elements of the intrinsic matrix of the pinhole model and several distortion terms.
camera system (multiple cameras)¶
PyMVG represents a camera system with the MultiCameraSystem class. You create an instance with a list of individual camera instances. The class provides additional methods for triangulation of 3D points and so on.
