Camera calibration denotes the task of estimating the projective mapping between 3D world and the camera image plane. Most of the modern cameras have multiple image and video acquisition modes, which differ in image resolution, field of view or aspect ratio. Each mode should be treated as an independent device, and therefore independently calibrated. This straightforward solution implies the acquisition...
An indispensable pre-processing step for image-based 3D reconstruction or photogrammetry tasks is undistortion, which is employed for correcting the non-linear projection of the surface points of objects onto the image plane due to lens distortion. To deal with this undesirable artifact, state-of-the-art methods focus on directly recovering the 2D coordinates of image points from distorted images,...
