autoware_euclidean_cluster
Purpose
autoware_euclidean_cluster 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
| Name | Type | Description |

- style(pre-commit): autofix
- corresponding part of VoxelGridBasedEuclideanCluster used in detection by tracker
- style(pre-commit): autofix
- cluster point number diag removed
- add max_num_points_per_cluster
- euclidean cluster diag impl restored
- add comments for the parameters
- readme updated
- diag removed
- random point and exclude extreme large cluster
- fix index problem
- Refactor voxel grid parameters to improve clarity and functionality
- Renamed [max_num_points_per_cluster]{.title-ref} to [max_voxel_cluster_for_output]{.title-ref} for better understanding of its purpose.
- Updated related code and configuration files to reflect this change.
- Adjusted logic in the clustering algorithm to utilize the new parameter name. This change enhances the readability of the code and aligns parameter naming with their intended use.
- Add uniform point cloud generation function for voxel clustering tests
- Introduced [generateClusterWithinVoxelUniform]{.title-ref} to create a uniform point cloud for testing.
- Updated test case to utilize the new function, adjusting the number of generated points.
- Modified [max_voxel_cluster_for_output]{.title-ref} to reflect the new clustering logic. This enhances the testing framework by providing a more controlled point cloud generation method, improving test reliability.
- Update voxel grid parameters for euclidean clustering
- Reduced [min_voxel_cluster_size_for_filtering]{.title-ref} from 150 to 65 to better accommodate medium-sized trucks, considering LiDAR occlusion.
- Added comments to clarify the rationale behind the new threshold. This change aims to improve the filtering process in the voxel grid-based euclidean clustering algorithm. * max_num_points_per_cluster removed This change aims to enhance code readability and maintainability in the voxel grid-based euclidean clustering implementation. * Update README.md to clarify clustering parameters Revised descriptions for [min_cluster_size]{.title-ref} and [max_cluster_size]{.title-ref} to specify that they refer to the number of voxels instead of points. This change enhances the clarity of the documentation for the euclidean clustering methods. * Update README.md to correct clustering parameter descriptions Modified the descriptions for [min_cluster_size]{.title-ref} and [max_cluster_size]{.title-ref} in the README to clarify that they refer to the number of points instead of voxels. This change improves the accuracy of the documentation for the euclidean clustering methods. * Add max_voxel_cluster_for_output parameter to README.md Introduced a new parameter [max_voxel_cluster_for_output]{.title-ref} to the documentation, specifying the maximum number of voxel clusters to output. This addition enhances the clarity of the clustering configuration options available in the euclidean clustering methods. ---------Co-authored-by: pre-commit-ci[bot] <66853113+pre-commit-ci[bot]\@users.noreply.github.com> Co-authored-by: badai nguyen <<94814556+badai-nguyen@users.noreply.github.com>>
