We present a learning-based method for synthesizing novel views of complex outdoor scenes using only unstructured collections of in-the-wild photographs. We build on neural radiance fields (NeRF), which uses the weights of a multilayer perceptron to implicitly model the volumetric density and color of a scene. While NeRF works well on images of static subjects captured under controlled settings, it is incapable of modeling many ubiquitous, real-world phenomena in uncontrolled images, such as variable illumination or transient occluders. In this work, we introduce a series of extensions to NeRF to address these issues, thereby allowing for accurate reconstructions from unstructured image collections taken from the internet. We apply our system, which we dub NeRF-W, to internet photo collections of famous landmarks, thereby producing photorealistic, spatially consistent scene representations despite unknown and confounding factors, resulting in significant improvement over the state of the art.

本论文提出了一种基于学习的方法，利用无组织的野外照片合成复杂场景的新视图，并介绍了一系列扩展NeRF的方法以解决自然图像中的一些问题，最终成功地构建了名称为NeRF-W的系统，能够从互联网上的无组织照片集合中重建场景并呈现接近于照片现实主义水平的合成视图。
