Using Geometric Constraints For Fisheye Camera Calibration
Since no evidence suggests that dioptric cameras (using fisheye lenses) have similar optical properties (e.g. rays are projected on a quadric surface) like central catadioptric cameras, the two-step model can lead to a erroneous correction for some fisheye lenses. For a dioptric (fisheye) camera, several … Return Document
