The Challenge
License Plates Vary Dramatically by Region and Condition
CCPD, RodoSol-ALPR, and UFPR-ALPR provided ALPR research foundations. Production systems require targeted regional coverage and real-world condition diversity.
License plate recognition systems must handle every plate format in your deployment region, under all lighting and motion conditions. ALPR trained on Brazilian or Chinese plates fails on European formats with different character sets, plate dimensions, and layout standards.
Public plate datasets suffer from single-country focus and controlled capture conditions that bear little resemblance to toll gates, parking garages, and street surveillance camera angles in production deployment.
LXT builds custom license plate datasets targeting your deployment geography with the correct plate standards, capture angles, and condition variations. We deliver the OCR ground truth, detection annotations, and attribute labels your ALPR pipeline needs.
Why Teams Upgrade
Limitations of Public License Plate Datasets
Standard benchmarks serve research well. Production deployments need more.
| Dataset | Primary Limitation | Impact |
|---|---|---|
| CCPD | Chinese plates only; controlled capture conditions; limited night and motion blur coverage | Regional lock |
| RodoSol-ALPR | Brazilian plates only; highway toll booth angles; limited to two plate formats | Narrow scope |
| UFPR-ALPR | Brazilian plates only; parking and traffic scenarios; limited geographic diversity | Regional lock |
| OpenALPR | Mixed crowdsourced quality; inconsistent annotations; limited attribute labels | Quality variance |
| AOLP | Taiwanese plates only; three scenario types; limited real-world capture variation | Geographic bias |

Need a custom configuration?
We've built datasets across dozens of domains and use cases. Let's scope yours.
Capturing Complexity
Edge Cases in License Plate Recognition
High-accuracy models handle rare attributes that public datasets miss.
Night Capture with IR Illumination
Retroreflective plates behave very differently under infrared vs. visible light. IR-specific training data is essential for night ALPR deployments.
High-Speed Motion Blur
Highway-speed plates with motion blur require augmentation-aware training data or targeted high-speed captures with rolling shutter characterization.
Dirty, Obscured, and Damaged Plates
Mud splashes, snow coverage, damage, and deliberate obscuring are common in real deployments. Production ALPR must remain robust to partial coverage.
Temporary, Trade, and Custom Plates
Dealer plates, temporary registrations, and vanity plates with non-standard character spacing and regional temporary plate formats.
Ground Truth Quality
Human-in-the-Loop Annotation
Precise annotation bridges raw data and learnable signal. Expert annotators deliver precision automated tools can't match.
Detection and Localization
Tight bounding boxes with corner keypoints per plate instance, including vehicle association links and multiple plate detection for trucks and trailers.
Character-Level OCR Annotation
Per-character bounding boxes with transcription, character confidence scores, and font/style labels for OCR model training.
Attribute and State Labels
Plate type classification (standard, temporary, trade, diplomatic), jurisdiction codes, and condition rating (clean, dirty, damaged, obscured).

Frequently Asked Questions
License Plate Dataset FAQs
Which plate formats and countries can you cover?+
We cover 80+ country and regional plate standards including all EU states, US and Canadian plates (all jurisdictions), Brazilian, Chinese, Japanese, Korean, Indian, and Middle Eastern formats. Custom geographic scopes are available.
How do you capture night and IR data?+
We use calibrated IR and near-IR camera setups at real-world ALPR deployment angles. Night captures are conducted at deployment-matched distances and speeds with your camera specification.
Can you provide character-level OCR ground truth?+
Yes. Each plate includes full character transcription plus per-character bounding boxes and confidence scores. Ground truth is validated against official plate databases where available.
How do you handle motion blur?+
We provide a range of motion blur levels characterized by vehicle speed and camera settings. For high-speed datasets, we use gated cameras or motion-blur simulation with documented parameters.
What annotation formats do you deliver?+
COCO JSON for detection, CSV for OCR transcription, and attribute metadata files. Custom schemas for your ALPR pipeline are available.
What does a custom license plate dataset cost?+
Projects range from $15K for single-country focused collections to $80K+ for multi-country datasets with full condition variation. Detailed quotes follow a scoping call.
