Camera Calibration Considering Scheimpflug Condition
Journal of the Visualization Society of Japan, 2004 Presently, a new calibration scheme for the camera under the Scheimpflug condition is proposed, which represents an exact projection from the object through the lens to the inclined image sensors and also handles the distortion by the lens theoretically.

Imaging Characteristics of Three Cameras Using the Scheimpflug Principle
Ophthalmic Research, 2009 We studied the handling and the potentials of three different cameras operating according to the Scheimpflug principle and which currently are commercially available. The examinations were performed with the cameras Topcon SL-45, Topcon SL-6E with cataract attachment and Zeiss SLC system.
