Traffic monitoring and tracking is a vital element of transportation system management. One of the underlying technologies used in intelligent transportation is Automatic Number Plate Recognition (ANRP). With the ANPR system, vehicle number plates are captured by cameras and then interpreted through the use of optical character recognition (OCR) to identify license plate numbers. ANPR is used in a variety of ways to support the efficiency and security in vehicle-based infrastructure. Typical ANPR applications include traffic monitoring, road law enforcement, speed and journey time measurement, toll collection, parking lot access control, etc.
Our client is a leading company in ANPR/LPR technology incorporated in Singapore. The company’s flagship product is their self-developed ANPR system which employs learning technique and neural network algorithms to run edge video analysis on IP cameras. With over 25 years professional experience in ANPR applications, their award-winning solution has been trusted for decades by local governments for border security and their immigration checkpoints. Other landmark installations include Singapore Parliament House, Hong Kong Jockey Club and Macau International Airport.
The project is a tender for implementing an Outdoor Video Camera System for speed enforcement purposes in South East Asia. The system comprises a series of components from the frontend imaging equipment to the backend management servers. With regard of the ANPR camera frontend system, it is to be installed at expressway roads as well as slip roads, and the camera needs to be able to capture the license plates at various speeds and during adverse day and night lighting conditions. The camera should also have the Optical Character Recognition (OCR) capability to recognize license plates of different colors, font size and types. And to facilitate 24/7 automated monitoring and alert the operator upon detection of anomalies, the system needs to enable intelligent analysis, both real-time and post-incident.
Instead of using just off-the-shelf IP cameras, where the risk of blur image may result in recognition difficulties, our client chose to customize their ANPR camera. This project-specific camera was done by integrating a high-end USB3.0 camera to an industrial high-performance x86 system to perform the computationally intensive image processing algorithms.
ARBOR’s Offering and Service
ARBOR’s EmCORE-i89M2 single board computer was selected by our client as the ANPR camera’s engine. The EmCORE-i89M2 features two USB 3.0 interfaces for USB 3.0 camera connection. With an Intel® Skylake Quad Core i7-6822EQ processor, the computer can provide the computing power necessary to process a vast amount of real-time data. Its Gigabit Ethernet interface enables high-speed streaming of videos and data to the remote viewing and management terminals.
The EmCORE-i89M2 was also selected because of its wide temperature capability from -40~85° C to ensure the operation in tropical areas. A heatsink is also attached to enhance the thermal performance. Plus, conformal coating is applied to the board to avoid short circuits in highly humid environments.
Considering the space constraints in the camera enclosure, compact size and ease of wiring were two major concerns of selecting the computer. The EmCORE-i89M2’s compact size of 3.5” form factor and ARBOR’s support on cabling design makes it well suited. Also, the support of M.2 storage greatly saves the space due to its ultra compact size and no need for extra cabling. Not to mention, it offers higher transfer speed than SATA interface.
