3D reconstruction¶

Typical input for 3D reconstruction: images and point clouds

Task: converting rough, imprecise, (distorted compared to gt) sketch to clean, complete 3D shape

rough -> requiring interpretation of noisy signals

High quality 3D modeling:

high resolution
sharp features

2D sketch¶

imcomplete -> requiring hallucination of missing parts

problem:

ambiguities ->
- hand-desinged priors
- limiting applications
- learn the shapes from data
- implicitly inferring relevant priors

3D sketch¶

Loss Functions¶

2D: use differentiable renderer and measure inconsitencies in 2D
3D: Chamfer / regularized Wasserterin

Terminology¶

-【artifact】就是合成图片中，不自然的、反常的、能让人看出是人为处理过的痕迹、区域、瑕疵等。
