autoware_euclidean_cluster_object_detector

Purpose

autoware_euclidean_cluster_object_detector is a package for clustering points into smaller parts to classify objects.

This package has two clustering methods: euclidean_cluster and voxel_grid_based_euclidean_cluster.

Inner-workings / Algorithms

euclidean_cluster

pcl::EuclideanClusterExtraction is applied to points. See official document for details.

voxel_grid_based_euclidean_cluster

A centroid in each voxel is calculated by pcl::VoxelGrid.
The centroids are clustered by pcl::EuclideanClusterExtraction.
The input points are clustered based on the clustered centroids.

Inputs / Outputs

autoware_euclidean_cluster_object_detector

Purpose

autoware_euclidean_cluster_object_detector is a package for clustering points into smaller parts to classify objects.

This package has two clustering methods: euclidean_cluster and voxel_grid_based_euclidean_cluster.

Inner-workings / Algorithms

euclidean_cluster

pcl::EuclideanClusterExtraction is applied to points. See official document for details.

voxel_grid_based_euclidean_cluster

A centroid in each voxel is calculated by pcl::VoxelGrid.
The centroids are clustered by pcl::EuclideanClusterExtraction.
The input points are clustered based on the clustered centroids.

autoware_euclidean_cluster_object_detector

Purpose

autoware_euclidean_cluster_object_detector is a package for clustering points into smaller parts to classify objects.

This package has two clustering methods: euclidean_cluster and voxel_grid_based_euclidean_cluster.

Inner-workings / Algorithms

euclidean_cluster

pcl::EuclideanClusterExtraction is applied to points. See official document for details.

voxel_grid_based_euclidean_cluster

A centroid in each voxel is calculated by pcl::VoxelGrid.
The centroids are clustered by pcl::EuclideanClusterExtraction.
The input points are clustered based on the clustered centroids.

Inputs / Outputs

autoware_euclidean_cluster_object_detector

Purpose

autoware_euclidean_cluster_object_detector is a package for clustering points into smaller parts to classify objects.

This package has two clustering methods: euclidean_cluster and voxel_grid_based_euclidean_cluster.

Inner-workings / Algorithms

euclidean_cluster

pcl::EuclideanClusterExtraction is applied to points. See official document for details.

voxel_grid_based_euclidean_cluster

A centroid in each voxel is calculated by pcl::VoxelGrid.
The centroids are clustered by pcl::EuclideanClusterExtraction.
The input points are clustered based on the clustered centroids.

Inputs / Outputs

autoware_euclidean_cluster_object_detector

Purpose

autoware_euclidean_cluster_object_detector is a package for clustering points into smaller parts to classify objects.

This package has two clustering methods: euclidean_cluster and voxel_grid_based_euclidean_cluster.

Inner-workings / Algorithms

euclidean_cluster

pcl::EuclideanClusterExtraction is applied to points. See official document for details.

voxel_grid_based_euclidean_cluster

A centroid in each voxel is calculated by pcl::VoxelGrid.
The centroids are clustered by pcl::EuclideanClusterExtraction.
The input points are clustered based on the clustered centroids.

Inputs / Outputs

Input

`input`	`sensor_msgs::msg::PointCloud2`	input pointcloud

Output

Name	Type	Description
`output`	`autoware_perception_msgs::msg::DetectedObjects`	detected objects
