[2303.00749] S-Nerf: Neural Radiance Fields For Street Views
Di: Ava
We synthesize views by querying 5D coordinates along camera rays and use classic volume rendering techniques to project the output colors and densities into an image. Because volume rendering is naturally differentiable, the only input required to optimize our representation is a set of images with known camera poses. We describe how to effectively optimize neural radiance

S-NeRF: Neural Radiance Fields for Street Views
Neural radiance fields (NeRF) have become an effective method for encoding scenes into neural representations, allowing for the synthesis of photorealistic views of unseen views from given input images. However, the applicability of traditional NeRF is significantly limited by its assumption that images are captured for object-centric scenes with a pinhole
Neural Radiance Fields (NeRFs) aim to synthesize novel views of objects and scenes, given the object-centric camera views with large overlaps. However, we conjugate that this paradigm does not fit the nature of the street views that are collected by many self-driving cars from the large-scale unbounded scenes.
We introduce S-NeRF, a robust system to synthesizing large unbounded street views for autonomous driving using Neural Radiance Fields (NeRFs). This project aims to enhance the realism and accuracy of street view synthesis and improve the robustness of NeRFs for real-world applications. (e.g. autonomous driving simulation, robotics, and Recent advances in Neural Radiance Fields (NeRF) have shown great potential in 3D reconstruction and novel view synthesis, particularly for indoor and small-scale scenes. However, extending NeRF to large-scale outdoor environments presents challenges such as transient objects, sparse cameras and textures, and varying lighting conditions.
This decouples the appearance component, which includes local features, and the shape component, which consists of global features, and utilizes them to construct a neural radiance field. These neural priors are then employed for rendering novel views. The novelty of SSNeRF lies in its sparse-view-specific augmentations and semi-supervised learning mechanism. In this approach, the teacher NeRF generates novel views along with confidence scores, while the student NeRF, perturbed by the augmented input, learns from the high-confidence pseudo-labels.

Novel view synthesis aims to generate new perspectives from a limited number of input views. Neural Radiance Field (NeRF) is a key method for this task, and it produces high-fidelity images from a comprehensive set of inputs. However, a NeRF’s performance drops significantly with sparse views. To mitigate this, depth information can be used to guide
NeRF. Neural Radiance Fields represent a scene with a multilayer perceptron (MLP) that maps a 3D position and direction to a density and radiance that can be used to syn-thesize arbitrary novel views with volumetric rendering [42]. Typically this representation is trained per scene with a loss measuring photometric consistency with respect to a collec-tion of posed RGB images. If the
