Geometric model of image formation in Scheimpflug cameras [PDF]
, 2016 We present a geometric model of image formation in Scheimpflug cameras that is most general. Scheimpflug imaging is commonly used is scientific and medical imaging either to increase the depth of field of the imager or to focus on tilted object surfaces. Existing Scheimpflug imaging models do not take into account the effect of pupil magnification (i.e.

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.
