Requirements

Python 3.6.9 (& 2.7), Cuda 10.2, PyTorch, ROS Melodic, RTAB-Map

For Mask R-CNN install TensorFlow 1.3 and Keras 2.0.8

For better performances,install RTAB-Map with recomended/optional dependencies

Installation

1. Project dependencies

   sudo apt-get install python3-pip python3-yaml python3-catkin-pkg-modules python3-rospkg-modules python3-empy
   pip3 install torch torchvision cython
   pip3 install opencv-python pillow pycocotools matplotlib scikit-learn rospkg catkin_pkg

2. Necessary tricks to use python 3 with ros

   • This project is based on python3, however ROS has not changed to python3. When the next ROS distribution will be out on python3, this sequence will become obsolete.

   • Because of issues with python3 and ROS, the project uses a workspace dedicated to python3.

   mkdir catkin_ws_py3
   cd catkin_ws_py3
   mkdir src
   cd src
   catkin_init_workspace
   cd ..
   wstool init 
   wstool set -y src/geometry2 --git https://github.com/ros/geometry2 -v 0.6.5 
   wstool up 
   cd src
   git clone -b melodic https://github.com/ros-perception/vision_opencv.git 
   cd ..
   catkin_make --cmake-args -DCMAKE_BUILD_TYPE=Release -DPYTHON_EXECUTABLE=/usr/bin/python3  -DPYTHON_INCLUDE_DIR=/usr/include/python3.6m -DPYTHON_LIBRARY=/usr/lib/x86_64-linux-gnu/libpython3.6m.so 
   source devel/setup.bash

3. Clone the repo

   cd catkin_ws_py3/src
   git clone https://github.com/introlab/dotmask.git
   cd ..
   catkin_make --cmake-args -DCMAKE_BUILD_TYPE=Release -DPYTHON_EXECUTABLE=/usr/bin/python3  -DPYTHON_INCLUDE_DIR=/usr/include/python3.6m -DPYTHON_LIBRARY=/usr/lib/x86_64-linux-gnu/libpython3.6m.so 
   source devel/setup.bash

4. Download the NN

   • You need to download the desired neural network from their original repo.

   YOLACT and YOLACT++:

   cd catkin_ws_py3/src/dotmask/nn
   git clone https://github.com/dbolya/yolact.git

   • For YOLACT++ you need to compile DCNv2, this may require elevated permissions

     cd catkin_ws_py3/src/dotmask/nn/external/DCNv2
     python3 setup.py build develop

   Mask R-CNN:

   cd catkin_ws_py3/src/dotmask/nn
   git clone https://github.com/matterport/Mask_RCNN.git

5. Download the NN weigths

   Download the weigths and place them in the "catkin_ws_py3/src/dotmask/weights" folder of this repo.

   • Those links are from the orignal repos

Benchmarking on TUM

1. Start RTABMap-ros

   roslaunch dotmask dotmask-tum.launch

2. Start DOTMask

   • With YOLACT

   source ~/catkin_ws_py3/devel/setup.bash
   cd ~/catkin_ws_py3/src/dotmask/src
   python3 dotmask_node.py --nn=yolact --input=tum

   • With YOLACT++

   source ~/catkin_ws_py3/devel/setup.bash
   cd ~/catkin_ws_py3/src/dotmask/src
   python3 dotmask_node.py --nn=yolact++ --input=tum

   • With Mask R-CNN

   source ~/catkin_ws_py3/devel/setup.bash
   cd ~/catkin_ws_py3/src/dotmask/src
   python3 dotmask_node.py --nn=mrcnn --input=tum

3. Start a TUM rosbag

   • To run the rosbag with rtabmap, make sure to do the following steps for the desired sequence.

   wget http://vision.in.tum.de/rgbd/dataset/freiburg3/rgbd_dataset_freiburg3_walking_static.bag
   rosbag decompress rgbd_dataset_freiburg3_walking_static.bag
   wget https://gist.githubusercontent.com/matlabbe/897b775c38836ed8069a1397485ab024/raw/6287ce3def8231945326efead0c8a7730bf6a3d5/tum_rename_world_kinect_frame.py
   python tum_rename_world_kinect_frame.py rgbd_dataset_freiburg3_walking_static.bag

   • Run the rosbag

   rosbag play --clock rgbd_dataset_freiburg3_walking_static.bag -r 0.1

Run DOTMask on xtion

• Opeeni2 is required to run the camera, install ros-melodic-openni2-launch with apt

1. Start RTABMap-ros

   roslaunch dotmask dotmask-xtion.launch

2. Start the xtion

   roslaunch openni2_launch openni2.launch depth_registration:=true

3. Start DOTMask

   • With YOLACT

   source ~/catkin_ws_py3/devel/setup.bash
   cd ~/catkin_ws_py3/src/dotmask/src
   python3 dotmask_node.py --nn=yolact --input=xtion

   • With YOLACT++

   source ~/catkin_ws_py3/devel/setup.bash
   cd ~/catkin_ws_py3/src/dotmask/src
