Back Office OCR Server
Tolling and Scalable
processing capacity

When you want a brain trust dedicated to your growing revenue collection operations.

Experience the automation benefits of our system’s sophisticated OCR engine that continuously learns from its exposure to the widest variety of plates from across North America. The intelligence of our system resides in not one but many “brains,” or “experts,” each processing the image from a different perspective. These experts provide confidence values per character and per plate, and their combined results ensure an exceptionally high level of accuracy. 

Perceptics' OCR solutions are scalable to meet your maximum throughput.

The Single OCR engine is designed for one to two lanes of traffic and can process up to 120,000 images a day. Our Desktop Enclosure option contains two to four OCR engines and can process 240,000 to 480,000 images a day. The solution containing six OCR engines is driven by a rack mounted PC, and is able to process 7.5 million images per month.

Benefits + Features

Uses adaptive segmentation to isolate plate number from its background

Multiple “experts”, including neural net, determine confidence values per character as well as for overall plate number

Matches reads to hot lists and sends alerts to other systems 

Recognizes even stylized and foreign fonts; plus plate type, state, province and country of origin

HTTP-based data interface

Load balancing front-end assures full scalability to match traffic volumes.
