Technology And Application Of The Automatic License Plate Recognition

Automatic vehicle recognition is an important application in the field of intelligenttransportation.The license plate recognition system plays an important role as a part of cityvehicle checking system. The license informations it gets provide important evidence timely fortraffic speeding corrected and traffic accident escaper cases.This paper introduces the design of city vehicle checking system scheme, the license platerecognition system scheme and detailed design is implemented in this environment. Bitmap classand image algorithm class was designed, the code is packaged into a dynamic library for DLL.This system provides a user interface to realize the reuse of the module. It’s convenient formaintenance and upgrade. Finally, testing is done to verify license plate recognition rate in thenatural environment. The main contributions of the thesis are as follows:1. Analysis of the feasibility of the system and demand, this paper presents the overallsystem design goal and the design scheme of automatic vehicle license plate recognition system,and introduces the composition and working principle, elaborats various levels of responsibilityand the function of each module distribution.2. Detailed design is put forward based on the overall design of vehicle license platerecognition system. And this paper studies the character recognition technology: plate location,character segmentation, character recognition and so on several key questions.3. Finally, the system is completed; summarize the full text and puts forward furtherresearch problems.
