从下图也可以看到NeRF和Gaussian在概念上的区别,左边是NeRF沿着光线查询连续 MLP,右边是Gaussian一组与给定光线相关的离散的高斯分布 difference between NeRF and Gaussian Splatting 首先简单介绍一下,3DGS是如何表示真实场景的,前面也有提过,在Gaussian Splatting中,3D世界用一组3D点表示,实际上是数百万个,大致在0.5...
与此相比,3D GS首先将这些三维高斯体投影到基于像素的图像平面上,这个过程被称为“splatting”。 之后,3D GS对这些高斯体进行排序并计算每个像素的值。如下所示,NeRFs和3D GS的渲染可以被视为彼此的逆过程。下面,我们首先定义三维高斯体,这是3D GS场景表示中的最小元素。接下来,我们描述如何使用这些三维高斯体...
Writers:Guikun Chen, Wenguan Wang PDF:A Survey on 3D Gaussian Splatting Abstract 3D Gaussian splatting (3D GS) has recently emerged as a transformative technique in the explicit radiance field and computer graphics landscape. This innovative approach, characterized by the utilization of millions of ...
3D GS的原理被详细阐述，包括使用优化的三维高斯体表示场景，以及从指定摄像机姿势生成图像的过程。从三维高斯体的属性、锥体剔除、splatting到基于像素的渲染，一系列关键步骤被系统性概述。通过引入并行计算与砖块（图块）技术，3D GS实现快速渲染，提高效率。优化过程聚焦于调整每个高斯的属性以适应特定场景...
We present a work-in-progress survey on 3D Gaussian Splatting compression methods, focusing on their statistical performance across various benchmarks. This survey aims to facilitate comparability by summarizing key statistics of different compression approaches in a tabulated format. The datasets evaluate...
As the latest research result of the explicit radiated field technology, 3D Gaussian Splatting (3D GS) replaces the implicit expression represented by Neural Radiated Field (NeRF) and has become the hottest research direction in 3D scene reconstruction. Given the innovative work and vigorous developm...
