Surfel-based Mapping using 3D Laser Range Data

Mapping of 3d laser range data from a rotating laser range scanner, e.g., the Velodyne HDL-64E. For representing the map, we use surfels that enables fast rendering of the map for point-to-plane ICP and loop closure detection.

Dependencies

• catkin
• Qt5 >= 5.2.1
• OpenGL >= 3.3
• libEigen >= 3.2
• gtsam >= 4.0

In Ubuntu 16.04: Installing all dependencies should be accomplished by

sudo apt-get install build-essential cmake libgtest-dev libeigen3-dev libboost-all-dev qtbase5-dev libglew-dev libqt5libqgtk2 catkin

Additionally, make sure you have catkin-tools and the fetch verb installed:

sudo apt install python-pip
sudo pip install catkin_tools catkin_tools_fetch empy

Build

If you do not have a catkin workspace already, create one:

cd
mkdir -p catkin_ws/src && cd catkin_ws
catkin init
cd src && git clone https://github.com/ros/catkin.git

Clone the repository in the src directory of your catkin workspace:

git clone https://github.com/jbehley/SuMa.git

Download the additional dependencies (or clone glow into your catkin workspace src yourself):

catkin deps fetch

For the first setup of your workspace containing this project, you need:

catkin build --save-config -i --cmake-args -DCMAKE_BUILD_TYPE=Release -DOPENGL_VERSION=430 -DENABLE_NVIDIA_EXT=YES

Where you have to set OPENGL_VERSION to the supported OpenGL core profile version of your system, which you can query as follows:

$ glxinfo | grep "version"
server glx version string: 1.4
client glx version string: 1.4
GLX version: 1.4
OpenGL core profile version string: 4.3.0 NVIDIA 367.44
OpenGL core profile shading language version string: 4.30 NVIDIA [...]
OpenGL version string: 4.5.0 NVIDIA 367.44
OpenGL shading language version string: 4.50 NVIDIA

Here the line OpenGL core profile version string: 4.3.0 NVIDIA 367.44 is important and therefore you should use -DOPENGL_VERSION = 430. If you are unsure you can also leave it on the default version 330, which should be supported by all OpenGL-capable devices.

If you have a NVIDIA device, like a Geforce or Quadro graphics card, you should also activate the NVIDIA extensions using -DENABLE_NVIDIA_EXT=YES for info about the current GPU memory usage of the program.

After this setup steps, you can build with catkin build, since the configuration has been saved to your current Catkin profile (therefore, --save-config was needed).

Now the project root directory (e.g. ~/catkin_ws/src/SuMa) should contain a bin directory containing the visualizer.

How to run and use it?

All binaries are copied to the bin directory of the source folder of the project. Thus,

1. run visualizer in the bin directory,
2. open a Velodyne directory from the KITTI Visual Odometry Benchmark and select a ".bin" file,
3. start the processing of the scans via the "play button" in the GUI.

In the config directory, different configuration files are given, which can be used as reference to set parameters for some experiments with other data. Specifying the right "vertical Field-of-View" (data_fov_up and data_fov_down) and the right number of scan lines (data_height) are the most important parameters.

See also the project page for configuration files used for the evaluation in the paper.
