A Four-step Camera Calibration Procedure with Implicit Image Correction
In geometrical camera calibration the objective is to determine a set of camera parameters that describe the mapping between 3-D reference coordinates and 2-D image coordinates. V...

Decoupling Photometry and Geometry in Dense Variational Camera Calibration
We introduce a spatially dense variational approach to estimate the calibration of multiple cameras in the context of 3D reconstruction. We propose a relaxation scheme which allow...
