autoware_traffic_light_category_merger

Overview

autoware_traffic_light_category_merger receives the Traffic Light (TL) classification result from Car/Pedestrian classifiers to merge into single classification result. The expect ROIs TL without classification result will be filled as Unknown.

Changelog for package autoware_traffic_light_category_merger

0.53.0 (2026-09-29)

• Merge remote-tracking branch 'origin/main' into prepare-0.53.0-changelog

• build(traffic_light_perception): split core/node CMake targets and expose public core headers (#13325)

  * refactor(autoware_traffic_light_category_merger): expose core header, split core/node CMake targets Move traffic_light_category_merger.hpp into include/autoware/traffic_light_category_merger/, and split the CMake target into ${PROJECT_NAME} (core) and ${PROJECT_NAME}_node (Node adapter linking the core). The Node header stays in src/. No behavior change; colcon build + colcon test pass (7 tests, 0 failures).

  * refactor(autoware_traffic_light_selector): expose core header, split core/node CMake targets Move traffic_light_selector.hpp into include/autoware/traffic_light_selector/, keeping traffic_light_selector_utils.hpp private in src/ (not part of the public API). Split the CMake target into ${PROJECT_NAME} (core: selector + utils) and ${PROJECT_NAME}_node (Node adapter linking the core). No behavior change; colcon build + colcon test pass (7 tests, 0 failures).

  * refactor(autoware_traffic_light_map_based_detector): expose core header, split core/node CMake targets Move traffic_light_map_based_detector.hpp into include/autoware/traffic_light_map_based_detector/, keeping traffic_light_map_based_detector_process.hpp private in src/ (not part of the public API). Since the public header declares functions taking image_geometry::PinholeCameraModel, add that include directly to the header instead of pulling it in transitively via the private process header. Split the CMake target into ${PROJECT_NAME} (core: detector + process) and ${PROJECT_NAME}_node (Node adapter linking the core). No behavior change; colcon build + colcon test pass (7 tests, 0 failures).

  * refactor(autoware_tensorrt_yolox): build TrtYoloXDetector as part of the core library tensorrt_yolox_detector.cpp implements core detection logic and was being compiled into ${PROJECT_NAME}_node (the Node adapter target) instead of ${PROJECT_NAME} (the core library). Move it to the core target so the core library does not depend on the node target for its own logic.

  • refactor(autoware_traffic_light_classifier): expose TrafficLightClassifier as the sole public header

  - Move traffic_light_classifier.hpp to include/autoware/traffic_light_classifier/ and forward-declare ClassifierInterface instead of including classifier/classifier_interface.hpp, so the classifier/*.hpp backends and classifier_params.hpp / traffic_light_classifier_node.hpp stay private under src/.

  - Split the CMake library target into ${PROJECT_NAME} (ROS-free classification core) and ${PROJECT_NAME}_node (rclcpp::Node adapter layer), mirroring the core/node separation already present in src/.

  - single_image_debug_inference_node and the node-level integration test now link against both libraries instead of recompiling every source file.

  • refactor(autoware_traffic_light_multi_camera_fusion): move headers under include/, split core/node CMake targets
  • refactor(autoware_traffic_light_arbiter): split core/node CMake targets
  • refactor(autoware_image_transport_decompressor): move core logic header to include, node header to src

  * refactor(autoware_crosswalk_traffic_light_estimator): move core logic header to include, node header to src, split core/node CMake targets ---------

0.52.0 (2026-06-30)

• Merge remote-tracking branch 'origin/main' into tmp/bot/bump_version_base
• test(autoware_traffic_light_category_merger): decouple merge core from node and add tests (#12885)
  • Extract the merge logic from TrafficLightCategoryMergerNode into a ROS-free TrafficLightCategoryMerger core (now a static function); the node only handles the ROS interface (sync, publish), with behavior unchanged.
  • Add node-level integration tests driving the real node over its ROS topics to pin the observable behavior before the extraction.
  • Add ROS-free unit tests for the merge core, covering ordering, header source, and the empty-car / empty-pedestrian / both-empty edge cases.
