@startuml

group main process
  start
  if (Receive a map?) then (yes)
  else (no)
    stop
  endif

  :Interpolate based on the received ego-vehicle's positions to align with sensor time;

  if (Could interpolate?) then (yes)
  else (no)
    stop

  :Detect markers (see "Detection Algorithm");

  :Calculate the distance from the ego-vehicle's positions to the nearest marker's position on the lanelet2 map;

  if (Find markers?) then (yes)
  else (no)
    if (the distance is nearby?) then (yes)
      stop
      note : Error. It should have been able to detect marker
    else (no)
      stop
      note : Not Error. There are no markers around the ego-vehicle
    endif
  endif

  :Calculate the correction amount from the ego-vehicle's position;

  if (Is the found marker's position close to the one on the lanelet2 map?) then (yes)
  else (no)
    stop
    note : Detected something that isn't a marker
  endif

  :Publish result;

Detection Algorithm

1. Split the LiDAR point cloud into rings along the x-axis of the base_link coordinate system at intervals of the resolution size.
2. Find the portion of intensity that matches the intensity_pattern.
3. Perform steps 1 and 2 for each ring, accumulate the matching indices, and detect portions where the count exceeds the vote_threshold_for_detect_marker as markers.

Sample Dataset

• Sample rosbag and map

This dataset was acquired in National Institute for Land and Infrastructure Management, Full-scale tunnel experiment facility. The reflectors were installed by Taisei Corporation.
