NeuS: Learning Neural Implicit Surfaces by Volume Rendering for Multi-view Reconstruction 通过体积渲染来学习神经隐式曲面,用于多视图重建 Abstract 我们提出了一种新的神经表面重建方法,称为NeuS,用于高保真地重建对象和场景。现有的神经表面重建方法,如DVR [Niemeyer等人,2020]和IDR [Yariv等人,2020],需要前景掩模...

在隐式几何表示与渲染的前沿，NeuS——一种全新的神经表面重建方法，以其独特的技术革新，成功解决了自遮挡物体和薄结构复杂重建的挑战。它以神经符号距离函数（SDF）的精确性与体积渲染的深度处理能力相结合，为复杂场景重建带来了前所未有的高质量表现，超越了IDR和NeRF的传统界限。NeuS的核心创新在于，它...
在这种情况下,有T(t)的加持,w是可以对遮挡进行感知的,缺点是我们在NeRF中得到的T并不是完美的,再加上几何算法和实际操作中的固有偏差,这个做法引入了很多的误差,最后效果并不好。 正如下图所示,左边那张图中,朴素方法直接将sigma(t)设置为了一个固定的分布,就是我们上面提到的fai(f(p(t))),很明显计算得...

We propose a multi-view stereo reconstruction algorithm which recovers urban scenes as a combination of meshes and geometric primitives. It provides a compact model while preserving details: irregular elements such as statues and ornaments are described by meshes whereas regular structures such as column...
The second stage of the reconstruction is the generalization of the two-view algorithm for the N-view case. This goal is accomplished by first reconstructing an initial framework from the first stage and then relating the additional views by finding correspondences between the new view and already...
OpenMVS (Multi-View Stereo)is a library for computer-vision scientists and especially targeted to the Multi-View Stereo reconstruction community. While there are mature and complete open-source projects targeting Structure-from-Motion pipelines (likeOpenMVG) which recover camera poses and a sparse 3D ...
(1)Reconstruction Loss 第一部分为在完整样本中,分别使用公共表示 和各视图表示 的重构损失,第二部分为在不完整样本中,使用公共表示 和各视图表示 的重构损失。其对应的计算如下: (2)Adversarial Loss 传统的GAN框架应用于多视图重构,将解码器作为生成器,即 ...
