LabelFusion is a pipeline to rapidly generate high quality RGBD data with pixelwise labels and object poses, developed by the Robot Locomotion Group at MIT CSAIL.
We used this pipeline to generate over 1,000,000 labeled object instances in multi-object scenes, with only a few days of data collection and without using any crowd sourcing platforms for human annotation.
Our goal is to enable researchers and practitioners to generate customized datasets, which for example can be used to train any of the available state-of-the-art image segmentation neural network architectures.
You can get started here generating your own dataset for your own object.
The images and videos below show some example labeled data generated using LabelFusion.
LabelFusion produces ground truth segmentations and ground truth 6DOF poses for multiple objects in scenes with clutter, occlusions, and varied lighting conditions. The key components of the pipeline are: leveraging dense RGBD reconstruction to fuse together RGBD images taken from a variety of viewpoints, labeling with ICP-assisted fitting of object meshes, and automatically rendering labels using projected object meshes. Raw data can be collected either using an automated robot arm, or simply hand-carrying the RGBD sensor. For the dense reconstruction, we use ElasticFusion.1 For the 3D human annotation step, we implemented an application on top of Director,2 a user interface and visualization framework. After the human annotation step, the rest of the pipeline is automated, and uses the aligned 3D object meshes to generate per-pixel object labels by projecting back into the 2D RGB images.

We recommend the best way to get started is by using our Docker distribution
Alternatively, you can build from source using our GitHub repository
Documentation lives on our GitHub.
You can now download the entire dataset here: full LabelFusion example dataset download, (500+ GB, will take a couple hours to download).
We are working on having smaller samples of the dataset available.
LabelFusion is described in our publication (To Appear at ICRA 2018).
