TOD โ Trolley Occupancy Detection
An independent AI research project investigating whether a low-cost computer vision device can predict trolley bay shortages in retail stores before they occur. The CamUnit โ a Raspberry Pi with a USB webcam โ mounts above a trolley bay and runs Astra LT, a custom-trained YOLOv8 vision model (mAP50: 0.956, trained on 1,750 images across 9+ Australian retail brands). Includes face detection gate for privacy โ any frame containing a person is discarded before analysis. Currently seeking IGA trial store partners in Melbourne's south-east.
