General 3D Room Layout from a Single View by Render-and-Compare

Teaser

By Sinisa Stekovic, Shreyas Hampali, Mahdi Rad, Sayan Deb Sarkar, Friedrich Fraundorfer, Vincent Lepetit

This repository contains a reimplementation of our work "General 3D Room Layout from a Single View by Render-and-Compare" that was presented at ECCV 2020.

Note

The reimplementation of the method might perform slightly differently in comparison to the published results.

This implementation contains only the contributions from our original work. To run the method with custom images, depth, plane segmentation, and semantic segmentation are required. Please see examples folder.

Introduction

We present a novel method to reconstruct the 3D layout of a room—walls, floors, ceilings—from a single perspective view in challenging conditions, by contrast with previous single-view methods restricted to cuboid-shaped layouts. Our approach is formalized as solving a constrained discrete optimization problem to find the set of 3D polygons that constitute the layout. In order to deal with occlusions between components of the layout, which is a problem ignored by previous works, we introduce an analysis-by-synthesis method to iteratively refine the 3D layout estimate.

Example Folder Structure

Current repository provides some of the inference examples from the ScanNet-Layout dataset. If you would like to test the method on your images, you first need to extract planes masks (e.g by PlaneRCNN) and semantic segmentation (e.g. by MSEG).

Provided examples use the following structure:

  • |--examples
    • |--------color - original color images from the ScanNet dataset (*.jpg)
    • |--------depth - corresponding depth maps from the ScanNet dataset (*.png)
    • |--------depth_filled - corresponding filled depth maps from the ScanNet dataset (*.png) (we used https://github.com/kujason/ip_basic)
    • |--------mseg_labels - MSEG network semantic labels predictions (*.png) (Please see https://github.com/mseg-dataset/mseg-semantic)
    • |--------mseg_confidence - MSEG network confidence predictions for the predicted semantic labels (*.png)
    • |--------planercnn_seg - PlaneRCNN network planes instance masks predictions (*.npy) (Please see https://github.com/NVlabs/planercnn)

Inference

First, setup the paths in rl_config.py file. Then, run the infer_layout_from_image.py. To visualize intermediate results, you can set plot_intermediate_results = True in rl_config.py.
