BundleSDF: Neural 6-DoF Tracking and 3D Reconstruction of Unknown Objects

CVPR 2023poster

We present a near real-time (10Hz) method for 6-DoF tracking of an unknown object from a monocular RGBD video sequence, while simultaneously performing neural 3D reconstruction of the object. Our method works for arbitrary rigid objects, even when visual texture is largely absent. The object is assu…

Neuralangelo: High-Fidelity Neural Surface Reconstruction

CVPR 2023poster

Neural surface reconstruction has been shown to be powerful for recovering dense 3D surfaces via image-based neural rendering. However, current methods struggle to recover detailed structures of real-world scenes. To address the issue, we present Neuralangelo, which combines the representation power…

Parallel Inversion of Neural Radiance Fields for Robust Pose Estimation

ICRA 2023poster

We present a parallelized optimization method based on fast Neural Radiance Fields (NeRF) for estimating 6-DoF pose of a camera with respect to an object or scene. Given a single observed RGB image of the target, we can predict the translation and rotation of the camera by minimizing the residual be…

Extracting Triangular 3D Models, Materials, and Lighting From Images

CVPR 2022oral

We present an efficient method for joint optimization of topology, materials and lighting from multi-view image observations. Unlike recent multi-view reconstruction approaches, which typically produce entangled 3D representations encoded in neural networks, we output triangle meshes with spatially-…
