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.
If you use our implementation in your academic work, please cite the corresponding paper:

- Qt5 >= 5.2.1
- OpenGL >= 3.3
- libEigen >= 3.2
In Ubuntu 22.04/20.04: Installing all dependencies is accomplished by:
$ sudo apt-get install -y build-essential cmake libeigen3-dev libboost-all-dev qtbase5-dev libglew-dev $ mkdir build && cd build
$ cmake .. -DCMAKE_BUILD_TYPE=Release -DOPENGL_VERSION=430 -DENABLE_NVIDIA_EXT=YES
$ make -j5
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 NVIDIAHere 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.
Now the project root directory should contain a bin directory containing the visualizer.
All binaries are copied to the bin directory of the source folder of the project. Thus,
- run
visualizerin thebindirectory, - open a Velodyne directory from the KITTI Visual Odometry Benchmark and select a ".bin" file,
- 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.
