  • I've read the contribution guidelines.
  • I've searched other issues and no duplicate issues were found.
  • I'm convinced that this is not my fault but a bug.

Description

  • Compare_map_segmentation's result is unstable when ego-vehicle moves at high speed or turns.

  • A large static objects' pointcloud remain even after compare_map_segmentation

  • White point: ground_segmentation result
  • Pink: compare_map_segmentation result
  • Green: downsampled map

Expected behavior

  • Compare_map_segmentation should remain stable regardless ego-vehicle's speed
  • Large static objects will be also removed successfully at high speed.

Actual behavior

  • Compare_map_segmentation is unstable when ego-vehicle moves fast or turn.
  • Even large static objects' pointcloud remain at high speed moving.

Steps to reproduce

  • Using logging_simulator
  • Test with high-speed moving vehicle rosbag
  • Rendering /perception/object_recognition/detection/pointcloud_map_filtered/pointcloud topic to check compare_map_segmentation result

Versions

No response

Possible causes

Additional context

  • An Option for lookup time should be added and set the pointcloud header time for transform during compare_map_segmentation
