[ros-users] probabilities of OccupancyGrid

[Stefan Kohlbrecher]

Hi,

have a look at slam_gmapping.cpp lines 621 to 633. This is the loop
that fills the OccupancyGrid message with data coming from gmapping.
Currently, there are only simple checks if the cells are occupied (set
to 100) , free (set to 0) or unknown (set to -1). This is where you
could do something more sophisticated.

regards,
Stefan
