ZIA Plate


Low-load and high-precision license plate recognition software utilizing AI technology, which supports not only cameras on general roads but also security management and improvement of customer satisfaction in various fields such as parking lots, factories, offices, hospitals, hotels, public facilities, financial institutions and retail stores.

Example of application: License plate detection

(Numbers are masked for privacy protection.)


Highly precise license plate recognition

Being equipped with a recognition engine utilizing AI technology makes it possible to read vehicle numbers with high precision.

Recognition Precision:95%or more
Recognition Speed:38ms (*Measured by DMP’s AI FPGA module ZIA C3)

Operable on edge devices

1/100 lower load than software OCR technology.
Provision in source code makes it possible to implement in customer’s target edge devices such as (CPUs, GPUs, or DMP’s AI processor ZIA DV720)

Applicable to various applications

ZIA Plate supports security management and customer satisfaction in various fields such as factories, offices, hospitals, hotels, public facilities, financial institutions, and retail stores in addition to roadside cameras.

Possible to recognize special plates and various countries plates

Possible to recognize special license plates and various countries license plates
By utilizing AI, it can recognize license plates with designs such as Mt. Fuji or Olympics. It also supports overseas license plates recognition by learning images.

Recommended Usage Environment


ZIA C3 Kit

On-premises / Cloud

Windows、Amazon Linux etc.(x86_64)

Stand-alone PC

Windows 10 (x64_64) or Ubuntu (x86_64)

Implementation Steps

1. Software Evaluation

Select evaluation environment (camera type, software operating device)
Prepare input image data (considering the number of pixels, shooting angle, external shooting environment conditions)
Prepare trained model (model supplied with ZIA Plate or prepared by customer)

2. Re-Training of Trained Model

Extract unrecognized image conditions
Collect images (training data) under the conditions to be strengthened and re-train

3. Software Implementation Field Test

Design and examine overall software operation system
 a.All edge processing
 b.Partial edge processing (edge & cloud environment)
Design and implement screen display (pre-processing / post-processing)
Perform field test in the actual usage environment

4. Operation / Maintenance

Possible to perform timely maintenance by re-learning the trained model regarding the occurrence of external factors. For example,
 1.Specification change of license plate display due to law revision
 2.Change of camera device
 3.Change of shooting angle, usage environment conditions
