The OctoMap library implements a 3D occupancy grid mapping approach, providing
|
|
data structures and mapping algorithms in C++ particularly suited for robotics.
|
|
The map implementation is based on an octree and is designed to meet the
|
|
following requirements:
|
|
* Full 3D model. The map is able to model arbitrary environments without prior
|
|
assumptions about it. The representation models occupied areas as well as free
|
|
space. Unknown areas of the environment are implicitly encoded in the map.
|
|
While the distinction between free and occupied space is essential for safe
|
|
robot navigation, information about unknown areas is important, e.g., for
|
|
autonomous exploration of an environment.
|
|
* Updatable. It is possible to add new information or sensor readings at any
|
|
time. Modeling and updating is done in a probabilistic fashion. This accounts
|
|
for sensor noise or measurements which result from dynamic changes in the
|
|
environment, e.g., because of dynamic objects.
|
|
* Flexible. The extent of the map does not have to be known in advance. Instead,
|
|
the map is dynamically expanded as needed. The map is multi-resolution so
|
|
that, for instance, a high-level planner is able to use a coarse map, while a
|
|
local planner may operate using a fine resolution.
|
|
close-up views.
|
|
* Compact. The map is stored efficiently, both in memory and on disk. It is
|
|
possible to generate compressed files for later usage or convenient exchange
|
|
between robots even under bandwidth constraints.
