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.
