RT-DETR Object Detection with ONNX Runtime
This project demonstrates how to run Ultralytics RT-DETR models using the ONNX Runtime inference engine in Python. It provides a straightforward example for performing object detection with RT-DETR models that have been exported to the ONNX format, a standard for representing machine learning models. RT-DETR, or Real-Time DEtection TRansformer, offers efficient and accurate object detection capabilities, detailed further in the RT-DETR research paper.
⚙️ Installation
To get started, you'll need to install the necessary dependencies. Follow the steps below.
Installing Required Dependencies
Install the core requirements using pip and the provided requirements.txt file this will install CPU-based inference, install the standard onnxruntime package. This version utilizes CPU resources for model execution. See the ONNX Runtime Execution Providers documentation for more information on different execution options.
pip install -r requirements.txt
Installing onnxruntime-gpu (Optional)
For accelerated inference using an NVIDIA GPU, install the onnxruntime-gpu package. Ensure you have the correct NVIDIA drivers and CUDA toolkit installed first. Consult the official ONNX Runtime GPU documentation for detailed compatibility information and setup instructions.
pip install onnxruntime-gpu
🚀 Usage
Once the dependencies are installed, you can run inference using the main.py script.
Execute the script from your terminal, specifying the path to your ONNX model, the input image, and optional confidence and IoU thresholds:
python main.py --model rtdetr-l.onnx --img image.jpg --conf-thres 0.5 --iou-thres 0.5
Arguments:
--model: Path to the RT-DETR ONNX model file (e.g.,rtdetr-l.onnx). You can easily export Ultralytics models to ONNX format. Find more models on the Ultralytics Models page.--img: Path to the input image file (e.g.,image.jpg).--conf-thres: Confidence threshold for filtering detections. Only detections with a score higher than this value will be kept. Learn more about thresholds in our guide on YOLO performance metrics.--iou-thres: Intersection over Union (IoU) threshold used for Non-Maximum Suppression (NMS) to remove redundant bounding boxes.
Adjust the --conf-thres and --iou-thres values based on your specific requirements for detection sensitivity and overlap removal.
