Description

When the TLR outputs an unknown result, the visualizer:

• Keeps outputting 'Adjusted position is out of image bounds.' to the terminal

• The border color of 'unknown' is green

Expected behavior

When the TLR outputs an unknown result, the visualizer:

• Should not output any errors to the terminal
• The border color of 'unknown' should be white

Actual behavior

When the TLR outputs an unknown result, the visualizer:

• Keeps outputting 'Adjusted position is out of image bounds.' to the terminal
• Turns the border color of 'unknown' to green

Steps to reproduce

1. launch logging_simulator.launch.xml ros2 launch autoware_launch logging_simulator.launch.xml map_path:=PATH_TP_MAP vehicle_model:=sample_vehicle sensor_model:=sample_sensor_kit vehicle:=false sensing:=true perception:=true planning:=false control:=false map:=true system:=false localization:=false rviz:=false
2. run rqt_image_view ros2 run rqt_image_view rqt_image_view and see ~/debug/rois topic

Versions

OS: Ubuntu22.04 ROS2: humble Autoware: latest

Possible causes

The condition in this section is not good. https://github.com/autowarefoundation/autoware.universe/blob/main/perception/traffic_light_visualization/src/traffic_light_roi_visualizer/shape_draw.cpp#L50-L52

Possible approaches

• [x] Very short term: Remove std::cerr https://github.com/autowarefoundation/autoware.universe/pull/8294
• [ ] Short term: Fix the condition for drawing unknown
• [ ] Medium to long term: Refactor overall (there are mysterious magic numbers and many variables with essentially the same name, fixed values set in various places within hpp/cpp files and global functions)

@miursh Miura-san, may I ask who is handling this issue? Thanks ;)

@kminoda @YoshiRi How about this?

[YoshiRi]

This is assigned to @tzhong518. If urgent, I will handle it.

I urgently need the numerous errors appearing in the terminal to be removed

@KhalilSelyan (cc: @tzhong518) Hi, thank you for the previous PR https://github.com/autowarefoundation/autoware.universe/pull/6985. However, the PR is flooding the terminal log (issue https://github.com/autowarefoundation/autoware.universe/issues/7924), so I will merge this temporary PR as a quick fix: https://github.com/autowarefoundation/autoware.universe/pull/8294

Would you consider handling this, not just with a quick fix but as a long term fix?
