GSLAM (A General SLAM Framework and BenchMark)

1. Introduction

1.1. What is GSLAM?

GSLAM is aimed to provide a general open-source SLAM framework and benchmark with following features :

-> 1. Share the same API while maintain compatibility with different SLAM systems (such as feature based or direct methods).

-> 2. Support Monocular, Stereo, RGB-D or any custom input types (SAR, IMU, GPS and so on).

-> 3. Provide high efficient implementations of SLAM util classes like SO3, SE3, Camera, IMU, GPS, Bundle and so on.

-> 4. Support other features like coorperation SLAM to build a singular map.

-> 5. Provide benchmark tools for SLAM performance evaluation, make it easy to compare between SLAM systems.

1.2. What we can do with GSLAM?

1. For SLAM developers : Everyone can develop their own SLAM implementation based on GSLAM and publish it as a plugin with open-source or not.
2. For SLAM users : Applications are able to use different SLAM plugins with the same API without recompilation and implementations are loaded at runtime.

2. Compilation and Install

2.1. Compile on linux (Tested in Ubuntu 14.04 and 16.04)

2.1.1 Install dependency

OpenCV : sudo apt-get install libopencv-dev

Qt : sudo apt-get install build-essential g++ libqt4-core libqt4-dev libqt4-gui qt4-doc qt4-designer

OpenGL: sudo apt-get install freeglut3 freeglut3-dev libglew-dev libglew1.10

2.1.2 Compile and insall GSLAM

mkdir build;cd build;
cmake ..;make;sudo make install

2.2 Compile on windows

Compile with CMake now is supported.

3. Start with GSLAM

3.1. Basic usages

Test modules with google test:

gslam Act=Tests --gtest_filter=*

Run a slam system with datasets:

gslam Dataset=(dataset file) SLAM=(the slam plugin)

3.2. Supported Datasets

GSLAM now implemented serveral plugins for public available datasets. It is very easy to play different datasets with parameter "Dataset" setted:

# Play kitti with monocular mode
gslam Dataset=<dataset_path>/odomentry/color/00/mono.kitti

# Play kitti with stereo mode
gslam Dataset=<dataset_path>/odomentry/color/00/stereo.kitti

# Play TUM RGBD Dataset (associate.txt file prepared)
gslam Dataset=<dataset_path>/rgbd_dataset_freiburg1_360/.tumrgbd

# Play TUM Monocular (images unziped)
gslam Dataset=<dataset_path>/calib_narrowGamma_scene1/.tummono

# Play EuRoC Dataset with IMU frames
gslam Dataset=<dataset_path>/EuRoC/MH_01_easy/mav0/.euroc

# Play NPU DroneMap Dataset
gslam Dataset=<dataset_path>/DroneMap/phantom3-village/phantom3-village-kfs/.npudronemap
gslam Dataset=<dataset_path>/DroneMap/phantom3-village/phantom3-village-unified/.npudronemap

The datasets are default to be played on realtime, and the play speed can be controled with "PlaySpeed":

gslam Dataset=<dataset_path>/odomentry/color/00/mono.kitti PlaySpeed=2.

The following dataset plugins are now implemented:

Name	Channels	Description
KITTI	Stereo,Pose
TUMMono	Monocular
TUMRGBD	RGBD,Pose
EuRoc	IMU,Stereo
NPUDroneMap	GPS,Monocular
CVMono	Monocular	Online camera or video dataset using opencv.

Users can also implement dataset plugins by own.

3.3. Implemented SLAM plugins

Name	ScreenShot	Description
DSO		code
ORBSLAM		code
SVO		code
TheiaSfM		code

3.4. Configuration with Svar

More parameters can be setted with Svar at file *.cfg. See more details of Svar at PILBASE.
