๐Ÿ‘‘ Live Queen Finder

๐ŸŽฏ Purpose

Live Queen Finder helps beekeepers spot queen bees during hive inspections using a mobile phone camera.

Open the Gratheon app, point the camera at a frame, and the detector draws a box around queen-like detections while you inspect.

๐ŸŽญ User Story

  • As a beekeeper inspecting a hive
  • I want live camera assistance while looking for the queen
  • So that I can find her faster and spend less time searching each frame

๐Ÿš€ Key Benefits

  • Field-ready: Works from the Gratheon app on a mobile phone with camera access.
  • No upload step: Camera frames are processed locally in the browser.
  • Free tier access: Available on the Free plan because inference runs on the user's device.
  • Faster inspections: Helps narrow attention to queen-like detections while the queen moves across the frame.

๐ŸŽ“ How to Use

  1. Open app.gratheon.com on your phone.
  2. Go to Queens โ†’ Live detector.
  3. Allow camera access when the browser asks.
  4. Move steadily across the comb and watch for the detection box.

๐Ÿ”ง Technical Overview

Live Queen Finder uses a YOLOv8 nano queen detector exported to ONNX and runs it in the browser with ONNX Runtime Web. It does not use Gratheon server-side image processing credits for inference.

The current baseline model reports these test-split metrics:

  • precision: 0.9727
  • recall: 0.8590
  • mAP50: 0.9187
  • mAP50-95: 0.6114

โš ๏ธ Current Limitations

  • Requires a modern browser and camera access.
  • Speed depends on the phone, browser, and lighting conditions.
  • It can miss queens or produce false positives, especially with blur, poor focus, crowded frames, or partially hidden queens.
  • Always confirm the detection visually before making queen-management decisions.
