Jun 16, 2023 · SDFStudio is a unified and modular framework for neural implicit surface reconstruction, built on top of the awesome nerfstudio project. We provide a unified …

Oct 15, 2022 · In this work, we introduce SPIDR, a new hybrid neural SDF representation. SPIDR combines point cloud and neural implicit representations to enable the reconstruction of higher …

Mar 18, 2024 · 比较常用的隐式表示有 符号距离函数Signed Distance Funciton(SDF)，占用场Occupancy Field，神经辐射场Neural Radiance Field（NeRF） 等。 本文将对几种隐式表示进 …

Why use NeRFs? An important question is: what is the difference? The instant NGP learns an SDF, so it isn’t an either/or question, right? A couple of people have mentioned to me that the …

By supervising camera rays between a scene and multi-view image planes, NeRF reconstructs a neural scene rep-resentation for the task of novel view synthesis. On the other hand, shadow …

By supervising shadow rays, we successfully reconstruct a neural SDF of the scene from single-view images under multiple lighting conditions. Given single-view binary shadows, we train a …

SDFStudio is built on top of nerfstudio. It implements multiple implicit surface reconstruction methods including: You can learn more about these methods here. We intend to integrate …

Oct 28, 2023 · SDF 的核心是一种连续的场景表征，NeRF的核心是体渲染。 因此本文是简单的关于SDF如何和体渲染串起来的粗糙总结 (即SDF2Density)。 (1) 网络预测density很难突变，网 …

05/10/2022 To make the comparison on ScanNet easier, we provide all quantitative and qualitative results of baselines here, including COLMAP, COLMAP*, ACMP, NeRF, UNISURF, …

那么是否有更好的建模方式呢？这里我们可以考虑使用有向距离场（Signed distance function 简称 SDF）来取代nerf建模。使用SDF的一大好处是，SDF函数本身在空间是连续的，这样子就不 …
