Abstract:
This thesis evaluates the performance of a vehicle detection technology, Automated License Plate Recognition (ALPR) camera systems, with regards to its ability to produce real-time travel time information in active work zones. A literature review was conducted to investigate the ALPR technology as well as to identify other research that has been conducted using ALPR systems to collect travel time information. Next, the ALPR technology was tested in a series of field deployments in both an arterial and a freeway environment. The goal of the arterial field deployment was to evaluate the optim

By using edge informant, the proposed is also effective and robust under variety of weather conditions. Firstly, the proportion of license plate is used to setup possible block sizes for edge image scanning. While doing block scanning, we could quick

From a digital vehicle image without presetting the location and size of the license plate, the proposed system can automatically find the location of the plate, isolate the letters and digits occurring in the plate, and then recognize the characters. The system includes three parts: license plate location, character isolation, and character recognition. Images

It has two main features as described in the following: (A) The so-called Color Repetition Density (CRD) is introduced to be a measure of license plate location. (B) The scan coding technique is developed to achieve license plate OCR with very low computation complexity. This algorithm is verified by the simulation using MATLAB. The corresponding results show the rate of success is 86%. In addition, it is further ported to TI’s DSP chip named DM-6437 to test its real performance of li

However, most of them operate under restricted conditions, such as static background, fixed shooting angle, and limited number of cars. In this research, as few constraints as possible on the working environment are considered. Our study focuses on the development of a real-time multiple vehicles license plate recognition system on embedded devices with algorithms in low computational complexity and camera shooting angle in large range.
