easynav_pointcloud_stack

This stack is part of the Easy Navigation (EasyNav) project developed by the Intelligent Robotics Lab. It is composed of the pointcloud_maps_builder package and the pointcloud_maps_manager package (currently under construction).

The PointcloudMapsBuilderNode subscribes to point cloud sensor data, downsamples and fuses it, and republishes the processed data for mapping or further processing.

Parameters

Parameter Name	Type	Default	Description
sensor_topic	string	points	Topic to subscribe for point cloud input
downsample_resolution	double	1.0	Resolution to use when downsampling
perception_default_frame	string	map	Target frame for fusing point clouds
