SMART PARKING SYSTEM USING AUTOMATIC VEHICLE NUMBER RECOGNITION

Abstract:

Number Recognition (VNR) is an image processing technology which uses efficient algorithms to detect the vehicle number from real time images. The system first detects the vehicle and then captures the image of the front view of the vehicle. Vehicle number plate is localized & characters are segmented. The system is designed for grayscale images so it detects the number plate regardless of its color. Template matching technique is used for the character recognition. The resulting vehicle number is then compared with the available database of all the vehicles so as to come up with information about the vehicles stored, if it is known in database then it is allowed otherwise it is not allowed to enter inside the parking area. . The vehicle information (such as passing time, date, vehicle number) is also stored in the different database to maintain the record. 

Algorithm for Automatic Vehicle Number Recognition is designed in MATLAB. The road barriers & traffic is controlled by using Microcontroller. System also contains LCD display to guide vehicles.

Smart toll tax collection system using Matlab for vehicle number plate recognition

Abstract:

Real time “Character Recognition & Pattern Recognition” is a latest research topic. Research Engineers all around the world are working on it. This technique is being used in many daily life applications to make human life much easy. Vehicle Number Recognition (VNR) is an image processing technology which uses efficient algorithms to detect the vehicle number from real time images. A toll road is a privately or publicly built road for which one pays a toll tax for its use. The building or facility in which a toll is collected may be called a toll plaza, toll station, or toll gate. The purpose of the research project (Smart Toll Tax Collection System Using Automatic Vehicle Number Recognition) is to automate the toll collection and to facilitate the toll collecting authorities. The system first detects the vehicle and then captures the image of the front view of the vehicle. Vehicle number plate is localized & characters are segmented. The system is designed for grayscale images so it detects the number plate regardless of its color. Template matching technique is used for the character recognition. The resulting vehicle number is then compared with the available database of all the vehicles so as to come up with information about the vehicle type & to charge toll tax accordingly. The system is then allowed to open road barrier for the vehicle & generate toll tax receipt. The vehicle information (such as passing time, date, toll amount) is also stored in the different database to maintain the record.

Algorithm for Automatic Vehicle Number Recognition is designed in MATLAB. The road barriers & traffic is controlled by using Microcontroller. System also contains LCD display to guide vehicles. Apart from toll collection system can also be used for security and authorized vehicles entrance in organizations & for automatic commercial parking systems. The proposed AVNR algorithm consists of some stages. In the first stage, Vertical edges of the acquired image are found. In the next stage, histogram analysis of its bit density is used for finding the possible candidate regions of license plate. Then in 3rd step deviation in rows is applied to locate exact candidate region. In the next stage, exact location of Number Plate is extracted by using some Morphological operators. Then in next step image region properties are found and by using bounding box Number Plate is segmented and each character is separated. In the last step each segmented image is compared with characters & digits templates which are already stored on computer & on the basis of its result Vehicle Number is found in String format. The system is implemented on hardware with the integration of Matlab, and its performance is tested on real images & a working prototype is developed. It is observed from the experiments that the developed system successfully detects and recognizes the vehicle number plate on real images of Pakistani vehicles.

RFID based attendance system with C# for GUI

Abstract:

            RFID (Radio Frequency Identification) is a technology that uses electromagnetic fields to identify objects in a contactless way. I have implemented real time “RFID BASED ATTENDANCE SYSTEM USING GUI” the GUI is developed using C# with .net platform and arduino microcontroller is used to interface RFID card reader with GUI as RFID card reader communicates through SPI protocol. The system works as a person brings the RFID card/tag near with RFID card reader, RFID card’s UID is read and sent to IT and administration departments wirelessly where GUI runs on server computer. RFID card’s UID is received and matched with database if it is found then attendance is registered there.

Introduction

I have designed and implemented system named “RFID Based Attendance System Using GUI”.  The main target was to design a wireless on campus attendance system with the features to maintain records of attendance and students identification using RFID technology. The RFID module reads the RFID card’s unique identification (UID) and sends that UID to Arduino microcontroller via SPI communication protocol which is located in any class room. Further Arduino sends that UID to IT department and chairman office where GUI is running servers. The UID is sent wirelessly. I have used Rf-433MHz modules for wireless communication between any class rooms to servers.

These Rf-433MHz modules are interfaced with Arduino UNO which receive UID and Arduino then serially transmit that data to server computer. The GUI is designed on visual studio using C# programming language interfaced with SQL database, as the GUI receives that RFID UID code then matches with database. If the RFID UID code is registered then attendance is registered. Our system uses three Arduino UNO boards for demo, one RF transmitter and two RF receiver modules, one RFID card reader and ten RFID cards are used as for testing.

C# based GUI design: 

Visual studio integrated development environment (IDE) as you use Windows Forms to build a relatively straightforward C# program. Windows Forms provide your project with components, such as dialog boxes, menus, buttons, and many other controls, that make up a standard Windows application user interface (UI). Fundamentally, these controls are just classes from the .NET Framework class library.

My GUI contains seven forms integrated to make a powerful desktop application. Our application maintains records, student database, adding new student to database, editing, deleting and online attendance page where name of person is shown as he/she brings RFID card near RFID card reader and also date, time & his/her record is saved.

Each page is described below.

Main Page:

This is main home page of GUI application; it contains four buttons Database view, Attendance page, Reports and Port config. One can navigate to any page by clicking any respective button.

 

Database View:

Database view page shows us the database, we have created, we can search, add new, edit and delete any person from database from here, we can also delete the entire database here and we can also print database in pdf file.

Add New:

On this page we can add new person in our database, it contains fields like SID, Name, Department, RFID, E-mail, Mobile some are mandatory to be filled before clicking “Save” button. After clicking on “Save” button a person is registered in the database.

Update New:

On this page we can update the registered person in our database first we will search them then we can edit and update, also we can delete any person from this page.

Attendance Page:

On this page, real time attendance is recorded and saved in record when a person brings RFID card near RFID card reader and his/her name is shown on screen for five seconds only.  Real time digital clock and date are also running every time on this page.

Reports:

On this page we can view recorded attendance of person, we can search attendance record by SID of person, we can also search attendance records within date ranges.

Port Config:

This page is used to define port name and baud rate to communicate with Arduino microcontroller. Port name is defined where we have plugged Arduino and baud rate is set which is defined in Arduino programming.

 Conclusion

“RFID Based Attendance System Using GUI” is designed and implemented, the predictable results have been achieved and the range of RF modules for wireless transmission is tested up to 70 meters. For further increase in range we would have to use Wifi modules or Xig Bee modules. I have tested my system using ten RFID cards only however, we can increase the database up to space available in system hardware. We can also print database or attendance records in pdf format.
