Agisoft Camera Calibration

Camera calibration is a necessary step in 3D computer vision in order to extract metric information from 2D images. Much work has been done, starting in the photogrammetry community (see [3, 6] to cite a few), and more recently in computer vision ([12, 11, 33, 10, 37, 35, 22, 9] to cite a few).
