Balanced Spherical Grid for Egocentric View Synthesis

(a) Our scalable capturing setup observes the holistic environment by casually swiping a selfie stick with an omnidirectional camera attached. (b) Then we optimize our balanced spherical feature grids which are tailored for the outward-looking setup. (c) EgoNeRF can quickly train and render high-quality images at nearby positions. Project
