autoware_ground_segmentation_cuda

Purpose

The autoware_ground_segmentation algorithms have been thoroughly tested with Autoware. However, due to latency and high computational cost when processing large pointcloud, the input pointcloud range has been limited by the crop_box_filter based on the ego-vehicle’s base_link. This can cause unwanted object loss, especially before a sloped road.

ground_segmentation_pipeline issue

Recently, GPU and CUDA-supported libraries such as cuda_blackboard and accelerated versions of autoware_pointcloud_preprocessor have been implemented. These can be leveraged to improve the performance of ground segmentation filter algorithms using CUDA/GPU.

This package reimplements the current scan_ground_filter of the ground_segmentation package to reduce latency and avoid the bottleneck caused by processing a large number of point clouds.

Inner-workings / Algorithm

The detailed algorithm is available in scan-ground-filter.md.

Parameters

{{ json_to_markdown(“perception/autoware_ground_segmentation_cuda/schema/cuda_scan_ground_segmentation_filter.schema.json”) }}
