The datasets below are available in different formats. All of them are gzipped so you need to run gunzip first to decompress them. .graph files contain raw sensor readings at registered poses in a binary format. You can convert them to .bt and .ot (the final occupancy map format) using the tool graph2tree in OctoMap, which also prints out different statistics for the conversion. You can also incrementally build maps from .graph files in the OctoMap visualization octovis. .ot (octree) files contain a final occupancy map in the OctoMap format. The nodes store the full (probabilistic) occupancy information. .bt (Bonsai tree or binary tree) files encode an occupancy map with only maximum-likelihood information (lossy compression), each node is either free or occupied. Both .ot and .bt files can be opened and visualized in octovis.
As an example, to create a 3D map "map.bt" from a scan-graph file "input.graph" at a resolution of 10cm, use:
graph2tree -i input.graph -o map.bt -res 0.1You can optionally limit the maxrange to 10m with "-m 10", see "graph2tree -h" for more options.
