Research And Develop Of Electronic Police Based On Da Vinci

Number of vehicles increased enormously along with development of community economy.The requirement for traffic control and safety management improved day by day.Reliability and high-efficiency intelligent transportation system carried out by electronic information technology became major development direction of traffic management.The technology about video detection of vehicle on the road is still in a fresh subject interiorly,and the practical application is still a long way to go.There are many theoretical algorithms about video detection,but how to choose an applied platform that can support the algorithms,how to develop some algorithms to deal with the practical application are very meaningful.And that is my major work.This paper is mainly to research the transplantation and optimization of license plate location and recognization algorithms on TMS320DM6467.And how to build a embedded systems that meet the requirements of the electronic police by Davinci platform.It describe several different methods to detect vehicle and analysis the superiority of video processing briefly in the paper. We have systematically studied the features and advantages of Davinci platform.A detailed description is given of the overall design of the high definition electronic police.Introduce of the technology of the program is divided into two parts,hardware and software.The key technologies are algorithms’ transplantation and optimization on DSP,as well as the embedded applications.The subject needs cooperation,and image processing algorithm is the core technology,but it is not the emphasis of this paper.We are concerned about embedded system design,algorithms’ transplantation and optimization.The difficult point of transplantation is mainly embodied in dual-core processing,in other words,how to send the data on ARM to DSP,and how to send DSP results to ARM.The focus of optimization is how to effectively use the software and hardware resources of Davinci to improve the efficiency of the entire system.Systematic design of embedded application is another focus of this article,which is a heavy work and covers a wide range.We have tested the Optimized embedded systems detailedly and comprehensively.The system fully meet the requirements of real time.We use general-purpose message queue mechanism to accomplish message communications.We use ftp to transmit files and data.And,this provide extendible standard interface.
