WebAug 6, 2024 · The user changes the camera pose, and NerF returns the corresponding image. The goal of NERF is to render high-quality images conditioned on the pose of the observer (the camera). NeRF is an example of a neural rendering technique- we explicitly control one of the properties of the scene - the pose of the observer - to obtain rendered … WebIn this work, we propose a camera self-calibration algorithm for generic cameras with arbitrary non-linear distortions. We jointly learn the geometry of the scene and the accurate camera parameters without any calibration objects. Our camera model consists a pinhole model, radial distortion, and a generic noise model that can learn arbitrary ...
