Structured3D
Structured3D is a large-scale photo-realistic dataset containing 3.5K house designs (a) created by professional designers with a variety of ground truth 3D structure annotations (b) and generate photo-realistic 2D images (c).

Data
The dataset consists of rendering images and corresponding ground truth annotations (e.g., semantic, albedo, depth, surface normal, layout) under different lighting and furniture configurations. Please refer to data organization for more details.
To download the dataset, please fill the agreement form that indicates you agree to the Structured3D Terms of Use. After we receive your agreement form, we will provide download access to the dataset.
For fair comparison, we define standard training, validation, and testing splits as follows: scene_00000 to scene_02999 for training, scene_03000 to scene_03249 for validation, and scene_03250 to scene_03499 for testing.
Errata
- 2020-04-06: We provide a list of invalid cases here. You can ignore these cases when using our data.
- 2020-03-26: Fix issue #10 about the basis of the bounding box annotations. Please re-download the annotations if you use them.
Tools
We provide the basic code for viewing the structure annotations of our dataset.
Installation
Clone repository:
git clone git@github.com:bertjiazheng/Structured3D.git
Please use Python 3, then follow installation to install PyMesh (only for plane visualization) and the other dependencies:
conda install -y open3d -c open3d-admin
conda install -y opencv -c conda-forge
conda install -y descartes matplotlib numpy shapely
pip install panda3d
Visualize 3D Annotation
We use open3D for wireframe and plane visualization, please refer to interaction control here.
