ManhattanSLAM

Authors: Raza Yunus, Yanyan Li and Federico Tombari

ManhattanSLAM is a real-time SLAM library for RGB-D cameras that computes the camera pose trajectory, a sparse 3D reconstruction (containing point, line and plane features) and a dense surfel-based 3D reconstruction. Further details can be found in the related publication. The code is based on ORB-SLAM2.

2. Prerequisites

We have tested the library in Ubuntu 16.04, but it should be easy to compile on other platforms. A powerful computer (e.g. i7) will ensure real-time performance and provide more stable and accurate results. Following is the list of dependecies for ManhattanSLAM and their versions tested by us:

• OpenCV: 3.3.0
• PCL: 1.7.2
• Eigen3: 3.3
• DBoW2: Included in Thirdparty folder
• g2o: Included in Thirdparty folder
• Pangolin
• tinyply

3. Building and testing

Clone the repository:

git clone https://github.com/razayunus/ManhattanSLAM

There is a script build.sh to build the Thirdparty libraries and ManhattanSLAM. Please make sure you have installed all required dependencies (see section 2). Execute:

cd ManhattanSLAM
chmod +x build.sh
./build.sh

This will create libManhattanSLAM.so in lib folder and the executable manhattan_slam in Example folder.

To test the system:

1. Download a sequence for one of the following datasets and uncompress it:

   • TUM RGB-D: https://vision.in.tum.de/data/datasets/rgbd-dataset
   • ICL-NUIM: https://www.doc.ic.ac.uk/~ahanda/VaFRIC/iclnuim.html
   • TAMU RGB-D: http://telerobot.cs.tamu.edu/MFG/rgbd/livo/data.html

2. Associate RGB images and depth images using the python script associate.py. You can generate an associations file by executing:

python associate.py PATH_TO_SEQUENCE/rgb.txt PATH_TO_SEQUENCE/depth.txt > associations.txt

3. Execute the following command. Change Config.yaml to ICL.yaml for ICL-NUIM sequences, TAMU.yaml for TAMU RGB-D sequences or TUM1.yaml, TUM2.yaml or TUM3.yaml for freiburg1, freiburg2 and freiburg3 sequences of TUM RGB-D respectively. Change PATH_TO_SEQUENCE_FOLDERto the uncompressed sequence folder. Change ASSOCIATIONS_FILE to the path to the corresponding associations file.
