A New Way to Factorize Linear Cameras

no code implementations22 Dec 2014 Feng Lu, Ziqiang Chen

The implementation details of factorizing the 3x4 projection matrices of linear cameras into their left matrix factors and the 4x4 homogeneous central(also parallel for infinite center cases) projection factors are presented in this work.

A General Homogeneous Matrix Formulation to 3D Rotation Geometric Transformations

no code implementations24 Apr 2014 Feng Lu, Ziqiang Chen

We present algebraic projective geometry definitions of 3D rotations so as to bridge a small gap between the applications and the definitions of 3D rotations in homogeneous matrix form.
