摘要

NeRF,或神经辐射场,是一种通过在有限的输入视点数量下最大化连续体素场景功能结果来产生复杂场景独特方式的技术。NeRF的主要目标是训练这个神经网络来预测给定3D坐标中任何给定3D点的辐射值。利用多层感知权值,神经辐射场(nrf)将物体的颜色和体积作为三维参数的函数进行复制。目前用于创建神经辐射场的方法包括分别改进每个场景的表示,这需要多个校准视图和大量的计算时间。我们开始用一个框架来解决这些问题,这个框架完全卷积地将NeRF置于图像输入中。NeRF能够在受限的照片中模拟几种常见的日常现象,例如波动的光线或短暂的障碍物,但是在预测在受限环境中拍摄的不移动主体的照片时是无效的。为了解决这些问题和从互联网下载的非结构化图片集的重建,我们开发了几个NeRF增强功能。通过检查来自知名网站的在线图像集,我们表明我们的方法创建了比最初的艺术状态更准确的新鲜透视图渲染。

A Neural Radiance Field-Based Architecture for Intelligent Multilayered View Synthesis
NeRF, or neural radiation field, is a technique for producing distinctive ways of complicated scenes by maximizing a continuous voxel scenery functional result with a constrained amount of input point of views. NeRF’s main goal is to train this neural network to forecast the radiance values at any given 3D point in the given 3D coordinates. Using multilayer perceptive weights, neural radiation fields (NRFs) replicate the color and volume of an object as a function of three-dimensional parameters. The current method for creating neural radiance fields includes improving the representation for each scene separately, which necessitates multiple calibrated views and a large amount of computation time. We begin to address these issues with a framework that completely convolutionally subjects a NeRF to picture inputs. NeRF is capable of modeling several common, everyday phenomena in restrained photos, such as fluctuating lighting or transitory obstruction, however it is ineffective while predicting pictures of immobile subjects that were shot in constrained environments. To resolve these problems and reconstructions from unstructured picture sets downloaded from the internet, we developed several NeRF enhancements. By examining online image collections from prominent websites, we show that our method creates fresh perspective renderings that are much more accurate than the beginning state of the art.
