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 Build Status

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

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.

Build and tested on ROS1 Kinetic, verified working in Indigo and Melodic
