The presented system (Unicam) offers a complex state-of-the-art machine vision equipment and technology to provide automated video image vehicle detection devices dedicated for traffic monitoring applications. The system provides real time video image capturing, digital signal processing, compression, storage, and transmission over communication interfaces. It uses proprietary artificial intelligence algorithms and special image processing modules to achieve highly accurate vehicles detection. According to the users' needs, the system can be used for detection of red-light violations at road intersections, speed measurement, traffic data collection, video recording, or surveillance. Yet another possible application of the system is surveys based on license plate recognition for transportation engineers, stolen car searching, or toll-tag data collection. The system functionality has been improved by coupling camera sensors with specialized real-time processing units and adding networking capability. Implementation of video detection algorithms, hardware design units, and networking features are also discussed.
