Hi @facontidavide.
In the literature, you will always find the ProbabilisticOccupancyMap
as the "map" to use. But in practice, the FrequencyOccupancyMap
provides better results for mapping. At least from my experience.
I usually use the ProbabilistiOccupancyMap
for perception applications, where the occupancy map has to be more dynamic and quick to change. The FrequencyOccupancyMap
is more conservative, it takes more effort (or observations) to go from occupiend to free.
And yes, the ProbabilisticOccupancyMap
does mimic Octomap
. But for integration, you can chose to use DDA like Octomap
or the more simpler integer Bresenham algorithm, which is faster. The outcome is not very different due to the amount of data that we usually use in perception.
