The camera is used to see the map, you can see it in the Map Editor, it has form of a green square, you can change its value who is located at the bottom right.

The Map Bottom is located at the bottom right of the window, you can change its value (it is to be 156.203.27.232 10:22, Decem(UTC)-320), but you can not delete it. Map bottom, is a yellow line that one can see in the Map Editor, it limits the field, if you cross that line or if a dynamic object crosses this line, the object or the player disappears / dies. You can also remove the grid in the bar that is at the top of the window. The grid is used to help you, the more you enlarge the grid unless you are accurate and shrink your grid more accurate you are, the grid is at the top of the window (advice: let the grid to 8 because it is adapted to the shape of objects). To name your map, you have to go down to the right and write the name of your map (the name must be coherent with your map).Do not forget to put your username to author, to who create the map. ]) within Map Editor require no advanced programming knowledge, for example if you wanted to add a concrete slab, you can either manually scroll through the list to find the concrete slab you want, or type "concrete" in the search bar right above the object listing and simply drag the property from the list onto the open space, you would simply find the desired item and drag it onto the grid. Additionally, the grid_map_visualization package helps to visualize grid maps as point clouds, occupancy grids, grid cells etc.The SFD map editor is a basic program in which players can design maps with various instances found in all of the current included maps in Superfighters Deluxthe sfd map Visualizations: The grid_map_rviz_plugin renders grid maps as 3d surface plots (height maps) in RViz.

OpenCV interface: Grid maps can be seamlessly converted from and to OpenCV image types to make use of the tools provided by OpenCV. ROS interface: Grid maps can be directly converted to and from ROS message types such as PointCloud2, OccupancyGrid, GridCells, and our custom GridMap message. For example, iterator functions for rectangular, circular, polygonal regions and lines are implemented. Users can apply available Eigen algorithms directly to the mapdata for versatile and efficient data manipulation.Ĭonvenience functions: Several helper methods allow for convenient and memory safe cell data access. to follow the robot) without copying data in memory.īased on Eigen: Grid map data is stored as Eigen data types.

This allows for non-destructive shifting of the map's position (e.g. Multi-layered: Developed for universal 2.5-dimensional grid mapping with support for any number of layers.Įfficient map re-positioning: Data storage is implemented as two-dimensional circular buffer. After multiple development cycles and use in many projects, the library is well tested and stable.

The package is available for ROS Indigo, Jade, and Kinetic and can be installed from the ROS PPA. From Péter Fankhauser via like to announce our new Grid Map package, developed to manage two-dimensional grid maps with multiple data layers and designed for mobile robotic mapping in rough terrain navigation.
