QCar2 ML Steering Weights

Weights and metadata for the QCar2 ROS 2 ML steering stack used in the rosbot_ws lane-keeping and LiDAR obstacle-avoidance project.

The primary model is an RF-DETR segmentation ONNX export used by rfdetr_onnx_lane_node to detect the lane mask and publish a steering target. The repository also includes fallback local weights used by the alternate YOLO/DL and ResNet lane-keeping modes in the workspace.

Primary Model Details

  • Architecture: RF-DETR segmentation medium
  • Task: lane and traffic-light segmentation for QCar2 track perception
  • Runtime: ONNX Runtime CPU or CUDA provider
  • Input tensor: input, float32 NCHW [1, 3, 432, 432]
  • Outputs:
    • dets: [1, 200, 4], normalized cx, cy, w, h
    • labels: [1, 200, 3], class logits
    • 4647: [1, 200, 108, 108], mask logits

Sample Scores

Sample project inference from eval/rfdetr_sample_predictions.json:

ClassConfidenceBBox XYXY
lane20.9720[6, 99, 640, 480]

ONNX Runtime smoke-test top prediction from eval/onnx_runtime_smoke_test.json:

ClassScoreNormalized Box
lane20.8555[0.5314, 0.5985, 0.9405, 0.7918]

These are smoke-test/sample scores, not a full benchmark.

Intended Use

This repository is intended for the QCar2 ROS 2 simulation/autonomy stack:

  • RF-DETR ONNX lane target publishing
  • ML lane keeping
  • LiDAR-triggered obstacle avoidance
  • one-way lane switching around obstacles

It is not a production autonomous-driving model and should not be used as a real vehicle safety system.

ROS 2 Usage

Expected workspace paths:

weights/car_track_v3_lane.onnx
weights/car_track_v3_lane.classes.txt

The main script uses those files with:

scripts/run_autonomy.sh

or through:

LANE_KEEPER=rfdetr scripts/run_lane_keeping.sh

Limitations

  • Trained/exported for this QCar2 simulation project and camera viewpoint.
  • Sample scores are from local smoke tests, not a held-out validation set.
  • Performance outside the lab track simulation is not guaranteed.
  • License is marked other until the exact upstream dataset/export license is confirmed.
