🛡️ Duplicate Detection Demo

See how the warehouse scanner prevents duplicate inventory entries

✨ Key Feature: The system now generates a unique "Visual ID" for each scanned item, preventing the same physical item from being added to inventory multiple times while tracking its location movements throughout the warehouse.

📸 Scenario 1: First Scan

New Item Detected

Detection:
TV detected (95% confidence)
Visual ID Generated:
tv_10-20-30-40_abc123
Location:
A1
✅ Result: Item added to inventory
First time seeing this TV - added as new item
14:03:45
🆕 TV scanned at location A1

⚠️ Scenario 2: Re-scan Same Location

Duplicate Detected

Detection:
TV detected (93% confidence)
Visual ID Match:
tv_10-20-30-40_abc123
⚠️ Already in database
Location:
A1 (Same location)
⚠️ Result: Duplicate prevented
Same TV in same location - updated last-seen time only
14:03:45
🆕 TV scanned at location A1
14:05:12
⏰ Last-seen updated at A1

📦 Scenario 3: Item Moved

Location Change Detected

Detection:

Visual ID Match:
tv_10-20-30-40_abc123

🔍 How Visual ID Works

The Visual ID is a unique fingerprint generated from three components:

1. Detection Class: tv
2. Bounding Box: 10-20-30-40 (normalized position)
3. Image Hash: abc123 (sample from captured image)

This combination creates a unique identifier that can recognize the same physical item even if it's scanned from slightly different angles or lighting conditions.
