Getting Started

Deploy
sudo docker run --rm --privileged --net=host --device /dev/dri/renderD128:/dev/dri/renderD128 \
  -v /proc/device-tree/compatible:/proc/device-tree/compatible:ro \
  ghcr.io/seeed-projects/recomputer-rk-cv/rk3576-yolov6:latest \
  python3 web_detection.py --platform rk3576 --model_path model/yolov6n.rknn --video_path video/test.mp4

REST API

Use the REST API to run inference. Copy the commands below.

Curl
curl http://localhost:8080/v1/chat/completions -d '{
  "model": "yolov6-rknn",
  "messages": [{"role": "user", "content": "Hello"}]
}'
Python
import requests

resp = requests.post(
    "http://localhost:8080/v1/chat/completions",
    json={"model": "yolov6-rknn", "messages": [{"role": "user", "content": "Hello"}]},
)
print(resp.json())

Model Details

Quick Start

1. Install Docker

Run the following commands on the development board to install Docker:

bash
# Download installation script
curl -fsSL https://get.docker.com -o get-docker.sh
# Install using Aliyun mirror source
sudo sh get-docker.sh --mirror Aliyun
# Start Docker and enable auto-start on boot
sudo systemctl enable docker
sudo systemctl start docker

2. Run the Project (One command, dual-mode preview)

This deployment is based on the YOLOv6 modules in reComputer-RK-CV. It runs COCO object detection with RKNN-Toolkit-Lite2 and provides browser preview, REST inference, and offline video processing.

Model Information

PropertyValue

Step A: Pull Images

bash
sudo docker pull ghcr.io/seeed-projects/recomputer-rk-cv/rk3588-yolov6:latest
sudo docker pull ghcr.io/seeed-projects/recomputer-rk-cv/rk3576-yolov6:latest

Step B: Run with One Click

Select the model size by changing --model_path.

For RK3576:

bash
sudo docker run --rm --privileged --net=host \
  --device /dev/dri/renderD128:/dev/dri/renderD128 \
  -v /proc/device-tree/compatible:/proc/device-tree/compatible:ro \
  ghcr.io/seeed-projects/recomputer-rk-cv/rk3576-yolov6:latest \
  python3 web_detection.py --platform rk3576 \
  --model_path model/yolov6n.rknn --video_path video/test.mp4

For RK3588:

bash
sudo docker run --rm --privileged --net=host \
  --device /dev/dri/renderD128:/dev/dri/renderD128 \
  -v /proc/device-tree/compatible:/proc/device-tree/compatible:ro \
  ghcr.io/seeed-projects/recomputer-rk-cv/rk3588-yolov6:latest \
  python3 web_detection.py --platform rk3588 \
  --model_path model/yolov6n.rknn --video_path video/test.mp4

Use model/yolov6s.rknn or model/yolov6m.rknn for the other catalog variants. Replace --video_path video/test.mp4 with --camera_id -1 for upload-only mode. Open http://<BOARD_IP>:8000 or /docs.


🔌 API Documentation

1. Model Inference Interface (Predict)

Endpoint: POST /api/models/yolov6/predict

Request Parameters (Multipart/Form-Data):

  • file: Optional image file to detect.
  • video: Optional MP4 file.
  • timestamp: Optional video timestamp in seconds; defaults to the first frame.
  • realtime: Optional boolean; with no upload, use the active camera or local-video frame.
  • conf: Optional request-level confidence threshold; defaults to 0.25.
  • iou: Optional request-level NMS IoU threshold; defaults to 0.45.

Usage Examples:

bash
curl -X POST "http://<BOARD_IP>:8000/api/models/yolov6/predict" \
  -F "file=@bus.jpg" -F "conf=0.25" -F "iou=0.45"
bash
curl -X POST "http://<BOARD_IP>:8000/api/models/yolov6/predict" \
  -F "video=@test.mp4" -F "timestamp=5.5"

Response Format (JSON):

json
{
  "success": true,
  "source": "uploaded image",
  "predictions": [
    {
      "class": "bus",
      "confidence": 0.91,
      "box": {"x1": 100, "y1": 120, "x2": 520, "y2": 430}
    }
  ],
  "image": {"width": 640, "height": 480}
}

2. System Configuration Interface (Config)

GET /api/config returns obj_thresh and nms_thresh. Update them with POST /api/config; request fields conf and iou override the global values.

The service also provides GET /api/health, GET /api/video_feed, POST /api/video/upload, POST /api/video/analyze, and video status, list, and download endpoints. Runtime files live under workspace/ unless RK_CV_WORKSPACE is set. Replacement models must retain the input size and YOLOv6 tensor layout expected by web_detection.py.

3. Command Line Arguments

ArgumentDefaultDescription
--platformRequiredrk3576 or rk3588; must match the image.
--model_pathRequiredOne of the packaged YOLOv6 RKNN files.
--camera_id1Camera index; -1 enables upload-only mode.
--video_pathNoneLooping local MP4; overrides the camera.
--class_pathCOCO labelsOptional replacement class list.
--host / --port0.0.0.0 / 8000FastAPI listen address and port.

Real-time Video Stream Interface (Video Feed)

Get the latest annotated MJPEG stream for browser preview:

  • Endpoint: GET /api/video_feed
  • Example Usage: <img src="http://<BOARD_IP>:8000/api/video_feed">
