MoreFusion is an object-level reconstruction system that builds a map with known-shaped objects, exploiting volumetric reconstruction of detected objects in a real-time, incremental scene reconstruction senario. The key components are:

Occupancy-based volumetric reconstruction of detected objects for model alignment in the later stage;
Volumetric pose prediction that exploits volumetric reconstruction and CNN feature extraction from the image observation;
Joint pose refinement of objects based on geometric consistency among objects and impenetrable space.

Installation

There're several options for installation:

Python project only: Python framework for pose estimation (e.g., training, inference, refinement).
ROS project for camera demonstration: ROS framework for object-level mapping with live cameras.
ROS project for robotic demonstration: ROS framework for robotic demonstration with object-level mapping.

NOTE: We have developed this project on Ubuntu 16.04 (and ROS Kinetic, CUDA 10.1), so several code changes may be needed to adapt to other OS (and ROS, CUDA versions).

Python project only

make install
source .anaconda3/bin/activate

ROS project for camera demonstration

cd ros/
make install
source ../.anaconda3/bin/activate
source devel/setup.sh

ROS project for robotic demonstration

robot-agent: A computer with CUDA and a GPU for visual processing.
robot-node: A computer with a real-time OS for a Panda robot.

@robot-agent

Same as above instruction: ROS project for camera demonstration.

@robot-node

cd ros/
catkin build morefusion_ros_panda
source devel/setup.sh

rosrun morefusion_ros_panda create_udev_rules.sh

Usage

Training & Inference

Pre-trained models are provided in the demos as following, so this process is optional to run the demos.

Instance Segmentation

cd examples/ycb_video/instance_segm
./download_dataset.py
mpirun -n 4 python train_multi.py  # 4-gpu training
./image_demo.py --model logs/XXX/XXX.npz

6D pose prediction

# baseline model (point-cloud-based)
cd examples/ycb_video/singleview_pcd
./download_dataset.py
./train.py --gpu 0 --centerize-pcd --pretrained-resnet18  # 1-gpu
mpirun -n 4 ./train.py --multi-node --centerize-pcd --pretrained-resnet18  # 4-gpu

# volumetric prediction model (3D-CNN-based)
cd examples/ycb_video/singleview_3d
./download_dataset.py
./train.py --gpu 0 --pretrained-resnet18 --with-occupancy  # 1-gpu
mpirun -n 4 ./train.py --multi-node --pretrained-resnet18 --with-occupancy  # 4-gpu
mpirun -n 4 ./train.py --multi-node --pretrained-resnet18  # w/o occupancy

# inference
./download_pretrained_model.py  # for downloading pretrained model
./demo.py logs/XXX/XXX.npz
./evaluate.py logs/XXX

Joint pose refinement

cd examples/ycb_video/pose_refinement
./check_icp_vs_icc.py  # press [s] to start

(base) root@7ceaf1e36560:~/ros_morefusion# rosrun franka_control_custom create_udev_rules.sh [rospack] Error: package 'franka_control_custom' not found

FIXME: current code assumes there are no multiple instances of the same class.But in the practical application will encounter such problems.how to solve and suggestions?
