Forward-facing(LLFF ) NeRF (Realistic Synthetic) DTU 业界方法 1. NVIDIA DRIVE Sim™构建了一个物理属性准确的仿真平台,能够快速、高效地进行大规模的自动驾驶汽车测试和验证。Demo如下,用NeRF进行重建可以做到虚拟和现实的实时融合,可以模拟一些复杂的道路情况,从而提供模拟数据: 为3维场景增加 2. Telsa(2021 ...
然而,LLFF为每个输入图像生成了一个大的3D体素网格,导致存储需求巨大(一个“Realistic Synthetic”场景超过15GB)。我们的方法仅需要5MB的网络权重存储空间(与LLFF相比压缩了3000倍),这甚至比任何单个场景的输入图像本身的存储空间还少。 6.4 消融研究 我们通过广泛的消融研究验证了算法的设计选择和参数(表2)。我们在...

重建的思想与几何重建思想有何不同,我们需要明确的是,NeRF属于可微渲染领域中的一个方法,这类方法的思路可以概括为,通过某种表达(可以是点云、mesh、图元、神经网络等)经过可微的渲染途径得到渲染图像;将渲染图像与真实图像作差得到loss;再通过梯度反向传播以修正表达,最终得到几何一致的三维表达与photo-realistic的渲染...
14.In an attempt to nerf users who abuse dribble moves and the turbo button for less-than-realistic results, 2K23 introduces the concept of adrenaline boosts. 15.With the substantial nerf to Scorpions, they no longer can win a battle on their own. ...
However, the automatic generation of shape, materials, lighting, and other aspects of scenes remains a challenging problem that, if solved, would make photo-realistic computer graphics more widely accessible. Concurrently, progress in computer vision and machine learning have given rise to a new ...

Neural Rendering包含所有使用神经网络生成可控(且photo-realistic)的新图片的方法。“可控”指人可以显式或隐式地控制生成新图片的属性,常见的属性包括:光照,相机内参,相机位姿(外参),几何关系,外观,语义分割结构。在这个大框架下,NeRF是一种比较受欢迎的可控相机位姿的Neural Rendering算法。但Neural Rendering这个方向...
