Package Description

include This package provides an implementation of a 3D costmap that takes in sensor data from the world, builds a 3D occupancy grid of the data for only one iteration.

nonpersistent_voxel_layer

Buy Me A Coffee

ROS2 drop in replacement to the voxel layer which does not persist readings through iterations when ray tracing or map maintenance is undesirable.

Bloom released, install via

sudo apt-get update && sudo apt-get install ros-eloquent-nonpersistent-voxel-layer

Created in response to need for a rolling local costmap layer to not persist readings due to a specific sensor being used. After looking through the community, it seems several people on ros answers have asked for a similar tool. This is to make that possible. This also helps with sensors like sonars, blob marking, radars, etc that aren’t dense enough to clear effectively.

parameters

Parameters as the same as found in the voxel layer, except the clearing bits. See the Voxel Layer API. The above example is a good minimum working example
