Camera calibration for 2.5-D X-ray metrology
This paper presents a new methodology for camera calibration of stereo X-ray projections. The image acquisition systems typically used in nondestructive evaluation result in views that are orthographic along one image axis and perspective along the other. A camera model for this sensing geometry, called the linear pushbroom model, is described. Four methods of calibration, which make different assumptions about what is known about the camera parameters, are presented and compared.
