Plenoxels: Radiance Fields without Neural Networks Sara Fridovich-Keil⇤ Alex Yu⇤ Matthew Tancik Qinhong Chen Benjamin Recht Angjoo Kanazawa UC Berkeley Abstract We introduce Plenoxels (plenoptic voxels), a
引入了plenoxel(plenoptic voxel),该方法用3D稀疏grid储存球谐函数表示场景,这种表示可以从校准图像通过梯度方法和正则化优化,而不需要任何神经成分。渲染比NeRF快了两个数量级。 Conclusion 提出一种实景渲染模型和新视点渲染法,和SOTA效果近似,但快了一两个数量级。 局限: 有伪影 超参数得每个场景都调 Introduction ...
PERF: Performant, Explicit Radiance Fields. 2021.12.10 The problem of volumetric reconstruction is formulated as a non-linear least- squares problem and solved explicitly without the use of neural networks. Similar to SLAM, using GN + PCG to solve this non-linear least- squares problem. ...
plenoxel（plenoptic voxel）是一种创新的三维稀疏网格技术，用于储存场景的球谐函数表示。这种方法能通过梯度方法和正则化优化从校准图像中提取信息，无需神经网络介入。plenoxel在渲染方面相较于NeRF快了两个数量级，表现出显著的加速效果。该研究提出了一种实景渲染模型和新视点渲染方法，其效果接近当前顶尖...
