Recognition system of moving vehicle based on video images mainly consists of two key technologies: recognition of vehicle_license_plate (VLP) and recognition of vehicle type. It not only finds wide application in ITS, but also is a hot point of research in computer vision, image processing and pattern recognition.
1. Feature extraction and recognition algorithm in object recognition: The recognition of moving vehicle is a typical system of automatic target recognition (ATR), while feature extraction and recognition algorithm are key problems in ATR.
The main purpose of recognition system for moving vehicles is to get variant features of vehicle in real-time, such as vehicle-shape, vehicle-logo, vehicle-license-plate and color of vehicle-body. By utilization of optimized recognition algorithms and information fusion techniques, the vehicle's type, and its color and license plate can be automatically recognized.
