Retail Shelf Monitoring System

A real-time retail shelf monitoring solution powered by computer vision and machine learning. The system leverages existing CCTV infrastructure to automatically detect out-of-stock (OOS) situations and product misplacements, enabling data-driven shelf management and faster restocking decisions.


🚀 Key Features

  • Real-time Shelf Analysis using YOLOv12-M for product detection
  • SKU Recognition via MobileNetV3 embeddings and FAISS similarity search
  • Planogram Compliance with automated grid generation and SKU matching
  • Tracking with SORT for temporal consistency across frames
  • Multi-threaded Architecture for high throughput and low-latency inference
  • Cross-platform Optimization with ONNX, OpenVINO, and TensorRT
  • Interactive Desktop App (PySide6) for visualization and alert management

⚙️ Processing Pipeline

CCTV Stream → Keyframe Selection → Shelf Detection →
Image Alignment → YOLOv12 Detection → SKU Recognition →
Grid Mapping → Temporal Consensus → Alert Generation →
Desktop UI Display → Staff Confirmation

Keyframe-based processing minimizes redundant computation, while tracking (SORT + Kalman Filter) ensures temporal stability across frames.


🧩 Core Components

  • Detection Model: YOLOv12-M fine-tuned on SKU-110k (mAP50–95 = 0.56)
  • SKU Recognition: 93% Top-1 accuracy on custom embeddings
  • Grid Generation: Automated DBSCAN-based clustering of shelf items
  • Alert Logic: Temporal consensus filtering to reduce false positives
  • App Interface: Live feed overlay, planogram visualization, alert confirmation

🧰 Technologies

  • Python, PyTorch, OpenVINO, TensorRT, OnnxRuntime, Pytorch-TensorRT, FAISS, PySide6, PostgreSQL, Redis
