WebWe propose a learning-based calibration method for trigonometric function models that represent distortion with over 180° projection of field of views. Unlike perspective projection for less than 180° projection of field of views, fisheye projection such as equisolid angle projection is valid for whole world coordinates. To calibrate fisheye camera models, we … WebInstead, a fisheye lens is in the panoramic category and therefore also restricted to cycles only for now. Change type to panoramic and then change the panorama type to “Fisheye Equisolid”. Now “Lens” will be …
