autoware_ground_filter

Purpose

The autoware_ground_filter is a node that remove the ground points from the input pointcloud.

Inner-workings / Algorithms

Detail description of each ground segmentation algorithm is in the following links.

Filter Name Description Detail
ground_filter A method of removing the ground based on the geometrical relationship between points lined up on radiation link

Inputs / Outputs

Input

Name Type Description
~/input/points sensor_msgs::msg::PointCloud2 reference points
~/input/indices pcl_msgs::msg::Indices reference indices

Output

Name Type Description
~/output/points sensor_msgs::msg::PointCloud2 filtered points

Parameters

Node Parameters

Name Type Default Value Description
input_frame string ” “ input frame id
output_frame string ” “ output frame id
has_static_tf_only bool false flag to listen TF only once
max_queue_size int 5 max queue size of input/output topics
use_indices bool false flag to use pointcloud indices
latched_indices bool false flag to latch pointcloud indices
approximate_sync bool false flag to use approximate sync option

Assumptions / Known limits

CHANGELOG

Changelog for package autoware_ground_filter

1.0.0 (2025-03-31)

  • chore: update version in package.xml
  • feat: re-implementation autoware_ground_filter as alpha quality from universe (#311) * add: [scan_ground_filter]{.title-ref} from Autoware Universe Source: Files copied from [Autoware Universe](https://github.com/autowarefoundation/autoware_universe/tree/b8ce82e3759e50f780a0941ca8698ff52aa57b97/perception/autoware_ground_segmentation). Scope: Integrated [scan_ground_filter]{.title-ref} into [autoware.core]{.title-ref}. Dependency Changes: Removed dependencies on [autoware_pointcloud_preprocessor]{.title-ref} to ensure compatibility within [autoware.core]{.title-ref}. Purpose: Focus on making [scan_ground_filter]{.title-ref} functional within the [autoware.core]{.title-ref} environment.
