Lumittari — Snow Estimation Demo

How It Works

End-to-End Detection Pipeline

From camera feed to billing data in five automated steps. The system processes video in real-time, detecting trucks, reading plates, and calculating snow loads without manual intervention.

1

Video Capture

Camera at the snow dumping polygon captures arriving trucks

2

Truck Detection

YOLOv12 identifies and localizes trucks in each frame

3

Plate Recognition

ALPR extracts license plate text with confidence scoring

4

Registry Lookup

Plate matched to vehicle registry for truck dimensions

5

Snow Estimation

Volume x SWE density = estimated snow weight

Step 1

Video Upload & Configuration

Users upload video footage from the snow dumping polygon. The interface supports drag & drop, video preview, and configurable detection parameters — duplicate threshold, frame skip, confirmation count, and confidence level.

Video Upload

Supported formats: MP4, AVI, MOV, MKV

Duration: 0:04 Resolution: 1920x1080

Detection Settings

Duplicate Threshold (seconds)

Minimum time between logging the same plate

Frame Skip

Process every Nth frame (higher = faster)

Confirmation Count

Detections required before logging

Confidence Threshold

Minimum detection confidence (0.1 - 0.95)

AI-Powered

Uses YOLO12 and fast-alpr for accurate truck and plate detection

Vehicle Registry

Matches plates to truck dimensions for automatic volume calculation

Snow Estimation

Combines cargo volume with SWE data to estimate snow weight

Step 2

Real-Time Video Processing

The AI processes video frame by frame, detecting trucks and reading license plates in real-time. Annotated frames stream to the browser via Server-Sent Events with live stats and a detection log sidebar.

Detection Results & Snow Estimation

After processing, the system presents a complete dashboard: summary statistics, matched vehicle information with cargo bed dimensions, snow volume/weight estimates using SWE data, and a searchable detection log with confidence scores.

Vehicle Registry

Database & Snow Event Log

The system maintains a vehicle registry with detailed truck specifications and cargo bed dimensions. Every detected snow delivery is logged with volume/weight estimates for billing and analytics.
