Description
Remake PR from #4995.
This PR add
object_merger
of far_objects to fusion for Camera-LiDAR-Radar fusion and refactor according to it.Until the tracking merger can operate stably, this PR temporarily added near_object and far_object mergers to the detection side and connected the far detection pipeline to tracking.
near_object
come from existing Camera-LiDAR-Radar fusion andfar_object
come from radar detection.I added radar lanelets filter parameter to detection launch to use config parameter from autoware.launch
To make it easier to understand parameters, I renamed parameter names and comment.

Tests performed
Tests by rosbag.
Red objects are detection/radar/far_object.
Other objects are tracking/objects.
Grid size is 10m.
I could confirm that the long-distance detection was working properly with tracking.
Notes for reviewers
Interface changes
None
Effects on system behavior
As adding faraway detection, dynamic objects at a distance become visible, so it effects to planning behavior.
