: 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],需要前景掩模作为监...

在这一领域，Niemeyer等人于2020年提出的DVR和Yariv等人同年推出的IDR是现有的神经表面重建方法，但它们都依赖前景遮罩提供监督，并且训练过程不稳定。为了克服这一问题，近期的神经方法，例如2020年NeRF及其变体，提出了使用体积渲染来构建更稳健的场景描述，但这种隐式场景描述在构建表面时缺乏表面约束，使得...
NeuS提出了一种新颖的方法，旨在通过体积渲染学习神经隐式表面，以实现多视图重构。这种方法的核心在于表示对象表面为符号距离函数（SDF）的零级集，同时开发了一种新的体积渲染技术来训练神经SDF表示。在NeuS中，重建的对象场景由两个函数表示：对象的表面S通过其SDF的零级集表示：S={x∈R^3|f(x)=0...

Framework of the reconstruction system. The system takes six synchronized figure skating sequences of single person as input, and outputs the 3D human skeleton estimation results. The overall framework of the system can be roughly divided into three steps, and the three proposals will work in thei...
While refraction causes magnification with mild distortion on the observed images, severe distortions in geometry reconstruction would be resulted if the refractive distortion is not properly handled. Different from the radial distortion model, the refractive distortion depends on the scene depth seen from...
NeuS的核心创新在于，它将曲面表示为SDF的零水平集，并通过无偏的体积渲染策略，摆脱了传统方法对前景掩模的依赖。这种方法允许神经网络在没有明确物体边界的场景中，精确捕捉物体的轮廓，即使面对深度突变和噪声，也能保持稳定性能，尤其是在遮挡密集和精细结构的场景中。在体积渲染过程中，NeuS巧妙地设计了...
The volume error of multi-view reconstruction is measured to be less than 5% of the true volume. We show that volume reconstruction accuracy is a function of the total number of 2D image planes and the number of views for calibrated phantom. In clinical in-vivo cardiac experiments, we show...
