Geometric Calibration for Cameras with Inconsistent Imaging Capabilities [PDF]
Sensors, 2022 Traditional calibration methods rely on the accurate localization of the chessboard points in images and their maximum likelihood estimation (MLE)-based optimization models implicitly require all detected points to have an identical uncertainty.

A Geometric Proof of Calibration [PDF]
Mathematics of Operations Research, 2009 We provide yet another proof of the existence of calibrated forecasters; it has two merits. First, it is valid for an arbitrary finite number of outcomes.

COMPARISON OF METHODS FOR GEOMETRIC CAMERA CALIBRATION [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2012 Methods for geometric calibration of cameras in close-range photogrammetry are established and well investigated. The most common one is based on test-fields with well-known pattern, which are observed from different directions.
