RESLAM: A real-time robust edge-based SLAM system

Please note that the code is still in the testing phase and I plan to update some parts soon!

In this work, we present RESLAM, a robust edge-based SLAM system for RGBD sensors. Edges are more stable under varying lighting conditions than raw intensity values, which leads to higher accuracy and robustness in scenes, where feature- or photoconsistency-based approaches often fail. The results show that our method performs best in terms of trajectory accuracy for most of the sequences indicating that edges are suitable for a multitude of scenes.

Building the framework

So far, the framework has only been built and tested on the following system.

Requirements

Sophus is now part of this repository (in thirdparty/Sophus).

Building on Windows and backwards compatibility might be added in the future.

Optional

Set the optional packages in the cmake-gui

Pangolin (for graphical viewer)

Build commands

git clone https://github.com/fabianschenk/RESLAM
cd RESLAM
mkdir build
cd build
cmake . ..
make -j

How to reproduce the results from the paper

If you enable multi-threading, results might differ a bit since float additions are not executed in the same order during each run!

TUM dataset

Download the sequence you want to test and specify the "associate.txt" file in the dataset_tumX.yaml settings file.

To generate an "associate.txt" file, first download the "associate.py" script from TUM RGBD Tools and then run

python associate.py DATASET_XXX/rgb.txt DATASET_XXX/depth.txt > associate.txt

in the folder, where your dataset is.

In the "RESLAM" directory:

build/RESLAM config_files/reslam_settings.yaml config_files/dataset_tum1.yaml

For evaluation of the absolute trajectory error (ATE) and relative pose error (RPE) download the corresponding scripts from TUM RGBD Tools.

Supported Sensors

Support for other sensors such as Orbbec Astra Pro and Intel RealSense will follow in the next weeks.
