SuperRay is a library for efficiently updating the occupancy map representation with point clouds. The update method based on both super rays and culling region shows high performance without compromising representation accuracy. Our library provides four different types of the occupancy maps - octree, quadtree, grid3D, grid2D - of which the implementations are based on OctoMap library. You can see the technical details of super rays and culling region based updates at here.
You can build the SuperRay library by using the CMake in the top-level directory. (The implementation of recent SuperRay library depends on OctoMap 1.9.0.) E.g. for compiling the library, run:
cd SuperRay-master
mkdir build
cd build
cmake ..
make
Binaries and libs will end up in the directories 'bin' and 'lib' of the top-level directory where you started the build.
You can use our library in your project by setting its include directories and lib files manually. But we suggest using the "find_package()" command in CMake as a more convenient way after installing this library. For installing it, run:
cd SuperRay-master
mkdir build
cd build
cmake ..
make install
Then you can link each type of occupancy map through the command of CMake, for example:
find_package(superray_octomap REQUIRED)
find_package(superray_quadmap REQUIRED)
find_package(superray_gridmap3d REQUIRED)
find_package(superray_gridmap2d REQUIRED)
See octomap README for further details and hints on compiling. Authors of OctoMap library describe how to compile the libraries on various platforms and IDEs.
We provide a ROS package that subscribes a pointcloud and updates an occupancy map in real time. Refer the realtime_occupancy_mapping project.
You can visualize the occupancy maps in RViz on ROS. Refer the occupancy_map_visualizer project.
