Research On Charging Control And Information Sharing System Of Automobile Parking

With the rapid development of the automotive industry,the problem of parking difficulties has become increasingly prominent.In order to improve the rational use efficiency of parking spaces and alleviate the pressure of parking difficulties,this project uses image processing technology and path planning principle to design a parking lot billing control and information sharing system.The system is divided into three parts,the main work is as follows:(1)License plate recognition and information storage system design.The system includes three parts: license plate image location,license plate recognition and license plate information storage.The license plate photographs collected by the camera are subjected to a series of processes such as image preprocessing,edge detection and BP neural network to obtain accurate information of the license plate.Use the Access database to create a license plate information table and save the license plate information.(2)Design of parking space detection and identification system.The system includes two parts: parking space detection and parking space status recognition.Firstly,the parking space detection uses two cameras to collect images of the parking spaces in the parking lot,and the collected images are subjected to image preprocessing,angle correction,Hough line detection,boundary tracking and image fusion to obtain the area of the dual camera.Complete parking image.The fused image is then used to identify the parking space status using a two-class algorithm.Finally,the parking space status table is established in the Access database to save the parking space status information.(3)Information sharing system design.The system includes three parts: path planning,interface design and data sharing.First,the parking space status obtained by the parking space detection and identification system is taken as the starting point from the entrance of the parking lot,and the shortest path is planned with the parking space closest to the entrance as the end point.Then,using the license plate information obtained by the license plate recognition and information storage system,the fee is calculated according to the entry and exit time of the same license plate number and the parking lot charging rule.Finally,the parking space information in the parking lot is uploaded to the Gaode map network library,so that the user canview the number of parking spaces and the location of the empty parking spaces in the parking lot through the Gaode map navigation.In this study,MATLAB is used for image processing to complete the license plate recognition system design and parking space recognition system design,share the collected information to the parking lot billing and information sharing system,and then use Microsoft Visual Studio to complete the parking lot billing and information sharing system design.To achieve the purpose of users can intuitively find vacant parking spaces.
