The Application Research Of Image Recognition Technology In Intelligent Transportation

With the development of digital image technology,image recognition technology is becoming more and more widely used in all aspects of life.Especially the rapid development of urbanization and the popularity of cars in recent years,making the country's traffic problems increased dramatically,resulting in image processing-based intelligent traffic technology has become an important research area of intelligent systems.Aiming at the application requirement analysis of intelligent transportation system,this paper designs a set of high-definition bayonet system which uses intelligent transportation.The main purpose of this system is to capture the motor vehicle pictures,vehicle number recognition,criminal face recognition and other characteristics of data collection,timely warning,to help police officers to track the criminals and so on.the paper mainly includes the following several parts:First,introduce the high-definition bayonet system involved in image recognition related technology.Including video motion object detection technology,image preprocessing technology,image recognition technology and related computer technology.Secondly,the application of face recognition technology and license plate recognition technology in the system is studied.Including the position of face and license plate detection,image preprocessing and image recognition,the design and implementation of the algorithm for some applications is made.Key research:(1)face detection positioning algorithm.Preferred to use the skin color to detect the image,remove the image without skin color information;And then use AdaBoost algorithm to detect the remaining images,get the image containing the face information;Finally,the binocular position detection is performed to obtain the accurate positive face image.(2)face feature extraction and recognition algorithm.This paper focuses on the feature extraction and matching of the SURF matching algorithm to identify the human face.(3)license plate recognition algorithm.Depth study of the license plate recognition algorithm,developed a license plate recognition system,and embedded inthe high-definition bayonet system to achieve accurate identification of the license plate.Finally,according to the system requirements analysis,development of high-definition bayonet system,embedded in the face recognition system and license plate recognition system is to achieve the algorithm envisaged function and business applications.
