HoW-3D: Holistic 3D Wireframe Perception from a Single Image

arXiv 2022 44.9 method, benchmark

TLDR

Proposes holistic 3D wireframe perception from single images, introducing ABC-HoW benchmark and Deep Spatial Gestalt model.

Reasoning

Strengths include a novel task, large-scale benchmark, and strong performance on invisible geometry inference. Weaknesses are reliance on synthetic data and focus on wireframes rather than full CAD reconstruction.

Deep Analysis

Innovations

  • Introduction of the holistic 3D wireframe perception (HoW-3D) task, requiring inference of both visible and invisible (NLOS) 3D wireframes from a single image.
  • ABC-HoW benchmark: a large-scale dataset of 12k single-view images with holistic 3D wireframe annotations derived from ABC CAD models.
  • Deep Spatial Gestalt (DSG) model that detects visible junctions and line segments and then infers NLOS 3D structures using Gestalt principles.

Methodology

The paper proposes the HoW-3D task and creates the ABC-HoW benchmark from ABC dataset CAD models. A Deep Spatial Gestalt model is designed to first learn visible 3D wireframe elements (junctions, line segments) from a single image, then infer the non-line-of-sight 3D geometry by applying Gestalt-inspired reasoning on the visible cues.

Key Results

The DSG model outperforms previous wireframe detectors in detecting invisible line geometry from single-view images and is competitive with methods that use high-fidelity point cloud inputs for 3D wireframe reconstruction.
