我们为每个场景渲染100个视图作为输入和200个用于测试,所有图像均为800×800像素。 复杂场景的真实图像:我们在大致朝前的图像捕获的复杂真实世界场景上展示结果(表1中的“Real Forward-Facing”)。这个数据集由8个场景组成,这些场景是用手持手机拍摄的(5个来自LLFF论文,3个是我们拍摄的),捕获了20到62张图像,我们...
就是把一个训练好的模型放在真实数据（Real）和NeRF数据（Sim）上去跑目标检测，然后算NDS（nuScenes det...

2.Mip-NeRF 360 CVPR2020的工作,室外无边界场景相关。Mip-NeRF 360: Unbounded Anti-Aliased Neural Radiance Fields 论文链接:https://arxiv.org/pdf/2111.12077.pdf 尽管神经辐射场(NeRF)已经在物体和空间的小边界区域上展示了不错的视图合成结果,但它们在“无边界”场景中很难实现,在这些场景中,相机可能指向...
Real scene modeling 图9 Make-It-3D支持在真实的复杂场景上实现高保真的3D创建 如图9所示,Make-It-3D可以成功将复杂场景的单张照片转换为3D模型,例如建筑和风景。这使用户可以轻松地建模,而这对于一些传统的3D建模技术可能很困难。 High-quality text-to-3D generation with diversity ...
Visualize training in real-time + interact with the scene Create and render out scenes with custom camera trajectories View different output types And more! ✏️ Support for multiple logging interfaces (Tensorboard, Wandb), code profiling, and other built-in debugging tools ...
Our model, which we dub "mip-NeRF 360" as we target scenes in which the camera rotates 360 degrees around a point, reduces mean-squared error by 54% compared to mip-NeRF, and is able to produce realistic synthesized views and detailed depth maps for highly intricate, unbounded real-world...
You will also need the LLFF code (and COLMAP) set up to compute poses if you want to run on your own real data. What is a NeRF? A neural radiance field is a simple fully connected network (weights are ~5MB) trained to reproduce input views of a single scene using a rendering loss...
