ANPR System Development Services
Engineer custom Automatic Number Plate Recognition (ANPR) systems. We specialize in edge-based OCR, toll plaza automation, mitigating motion blur, and real-time Kafka queues for sub-millisecond database lookups.
High-Performance ANPR Engineering
Off-the-shelf ALPR fails under challenging lighting or high velocities. We develop custom computer vision pipelines utilizing global-shutter sensors, synchronized IR illumination, and edge-based neural networks to read damaged and dirty plates with 99%+ accuracy.
- Edge-Based Plate Capture: Move inference to the camera edge via TensorRT and NPU acceleration, minimizing latency and network payload for toll plaza automation.
- Motion Blur & IR Illumination: Overcome high-speed smearing using 1/1000s exposure profiles, precise IR flash synchronization, and photometric plate normalization.
- Real-Time Database Lookups: Stream JSON payloads to Kafka event queues, enabling sub-millisecond matching against hotlists or access control schemas.
ANPR Infrastructure Engineering
Dirty & Damaged OCR
Train custom CNN models on degraded datasets. Utilize character-level synthesis and temporal plate tracking across multiple video frames to reconstruct heavily obscured tags.
Toll Plaza Automation
Build multi-lane, free-flow tolling pipelines. Sync stereoscopic triggers, weigh-in-motion (WIM) sensors, and vehicle classification bounding boxes into unified transactional events.
Kafka Event Queues
Decouple ALPR ingestion from database I/O. Use Apache Kafka for guaranteed, ordered event delivery ensuring zero dropped reads during peak rush-hour loads.

Technical ANPR FAQ
How do you handle severe motion blur at highway speeds?
We engineer optics pipelines combining global-shutter CMOS sensors, ultra-short exposure times (sub 1/2000s), and synchronized high-intensity IR strobes to freeze license plates travelling over 120mph.
How does edge OCR compare to cloud OCR?
Edge OCR runs the convolutional neural networks directly on the camera's NPU (like Ambarella or Hailo chips), returning a few bytes of JSON payload per read rather than streaming megabytes of raw video to a server. This is critical for bandwidth-constrained toll plazas.
Can the system read dirty or damaged plates?
Yes. We train our Automatic Number Plate Recognition models on heavily augmented datasets including simulated dirt, occlusion, snow, and dented geometry, coupled with temporal tracking to vote on the most probable alphanumeric string across 15+ consecutive frames.
