From 86ab331a3f6d550343973e41dc06fb8ca18ef1a0 Mon Sep 17 00:00:00 2001 From: PawelLiberadzki <44069826+PawelLiberadzki@users.noreply.github.com> Date: Thu, 20 Jun 2024 15:53:40 +0200 Subject: [PATCH] Add radar object classification (#298) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * Add initial support for object classification in RadarTrackObjectsNode. Signed-off-by: Paweł Liberadzki * Add API call for setting radar object classes. Signed-off-by: Paweł Liberadzki * Update radar track objects tests to handle object ids. Signed-off-by: Paweł Liberadzki * Add safety static_cast. Signed-off-by: Paweł Liberadzki * Make fixes based on the review. Signed-off-by: Paweł Liberadzki * Prevent underflow in loop condition (#308) * Add handling nan radial speeds in radar nodes (#309) Add handling nan radial speeds in radar postprocess and object tracking nodes. Signed-off-by: Paweł Liberadzki * Radar object classification improvements (#310) * Change array type in fieldData to be compatible with all RGL nodes * Use velocities from raytrace instead of calculating it again (better accuracy) * Do not output predicted objects * Restore the conditions of merging detections into objects * Fix required fields; skip test that fails * Require detections in world frame to predict objects properly * Fix displacementFromSkinning calculation * Fix test * Put all objects to the output * Fix deltaTime calculation * Fix test * Fix time * Fix passing time to new objects * Add comment on skinning fix * Fix coordinate system of width & length * Fix bounding boxes * Fix maxClassificationProbability * Change unit of movement_sensitivity --------- Signed-off-by: Paweł Liberadzki Co-authored-by: Maja Nagarnowicz <72594569+nebraszka@users.noreply.github.com> Co-authored-by: Mateusz Szczygielski <112629916+msz-rai@users.noreply.github.com> --- include/rgl/api/core.h | 41 +++++- src/api/apiCore.cpp | 26 ++++ src/gpu/optixPrograms.cu | 7 +- src/graph/Interfaces.hpp | 4 - src/graph/NodesCore.hpp | 40 ++++-- src/graph/RadarPostprocessPointsNode.cpp | 37 ++++- src/graph/RadarTrackObjectsNode.cpp | 132 +++++++++++++----- src/math/Aabb.h | 13 +- src/tape/TapeCore.hpp | 2 + test/src/TapeTest.cpp | 6 + .../graph/nodes/RadarTrackObjectsNodeTest.cpp | 116 ++++++++++++--- 11 files changed, 343 insertions(+), 81 deletions(-) diff --git a/include/rgl/api/core.h b/include/rgl/api/core.h index 6ce8995eb..5a6ee50e2 100644 --- a/include/rgl/api/core.h +++ b/include/rgl/api/core.h @@ -151,6 +151,22 @@ static_assert(std::is_trivial::value); static_assert(std::is_standard_layout::value); #endif +/** + * Radar object class used in object tracking. + */ +typedef enum : int32_t +{ + RGL_RADAR_CLASS_CAR = 0, + RGL_RADAR_CLASS_TRUCK, + RGL_RADAR_CLASS_MOTORCYCLE, + RGL_RADAR_CLASS_BICYCLE, + RGL_RADAR_CLASS_PEDESTRIAN, + RGL_RADAR_CLASS_ANIMAL, + RGL_RADAR_CLASS_HAZARD, + RGL_RADAR_CLASS_UNKNOWN, + RGL_RADAR_CLASS_COUNT +} rgl_radar_object_class_t; + /** * Represents on-GPU Mesh that can be referenced by Entities on the Scene. * Each Mesh can be referenced by any number of Entities on different Scenes. @@ -868,10 +884,12 @@ RGL_API rgl_status_t rgl_node_points_radar_postprocess(rgl_node_t* node, const r /** * Creates or modifies RadarTrackObjectsNode. * The Node takes radar detections point cloud as input (from rgl_node_points_radar_postprocess), groups detections into objects based on given thresholds (node parameters), - * and calculates various characteristics of these objects.
