AI-Driven 3D Surface Reconstruction: Neuralangelo

Neuralangelo is an innovative AI tool developed to enhance the reconstruction of dense 3D surfaces from multi-view images. It couples the representation power of multi-resolution 3D hash grids and neural surface rendering. The AI employs numerical gradients for higher-order derivatives computation and coarseto-fine optimization on hash grids for varying detail levels. Without auxiliary depth, Neuralangelo effectively reconstructs dense 3D surface structures from multi-view images, surpassing previous methods in terms of fidelity. This allows for detailed, large-scale scene reconstruction from RGB video captures.
