5. ABOUT THE ORGANISATION:
Done training from “509 Army Base Workshop",
Agra in OE Group.
It is one of the 8th biggest Army Workshops located
in India.
Deals generally with the testing as well as repairing of
the Army equipment’s use by the armed forces.
6. CONTINUED…
The whole organization is divided into 5 main
groups:
Optoelectronics (OE) Group;
Telecommunication (TL) Group;
RADAR(WLR and Flycatcher) Group;
Generation(GE) Group, and
Computer technology Group
7. INTRODUCTION TO
OPTOELECTRONICS GROUP
Optoelectronics is the combination of “Opto” and “Electronics”,i.e.
deals with the equipment's comprising properties of both.
The basic functions of this group is repairing and testing of various border
security equipments such as:
LRF LS-30-(LASER Range Finder equipment),
TPDK Tank-90,
LORROS (Long Range Reconnaissance & Observation System),
PNVD section(Passive Night Vision Device),etc.
10. INTRODUCTION
Other names of this technology are OCR(Optical Character
Recognition), or, LPR( Licence Plate Recognition) System,
etc.
It is a “Mass Surveillance system” and an image processing
technology, use extensively in USA to identify vehicles by
their license plates presently.
Apart from MATLAB, we can also prepare it by using various
other programming languages like Java, C#, Arduino, etc.
11.
12. APPLICATIONS OF ANPR SYSTEM
It is extensively use in the following listed areas:
Car Parking Management;
Traffic Control system;
Border Security;
Toll Management System;
Access Control system, etc.
13. PROCEDURE USED
The process of my project comprising of two toolboxes
of MATLAB ,they are:
Image Acquisition Toolbox-It helps in accessing the
webcam using MATLAB’s command window.
Image Processing Toolbox-It helps in all the basic
image processing steps as well as Morphological
operations.
15. PROCESS CONTINUED….
The steps use in the ANPR process are the following:-
Firstly, an image as an input is taken using webcam.
Then, using basic image processing steps to convert the color
image into the grayscale image.
Then, applying some Morphological Operations such as
Dilation(adding of pixels) and Erosion(removing of pixels).
After this, the grayscale image is converted into the binary
form and filtration is also done.
17. After this all the holes of image has been filled using some
MATLAB operations.
Then, Object reduction is also being done.
At last, characters are recognized and displayed onto the notepad
with a message of “Number registered ” or “Number not
registered”, as shown below:
18. Functions use in the MATLAB code
There are 6 user-defined methods use in the code .They
are:-
Number Plate extraction():- It is the main function and
use to extract the characters from the input image.
Controlling():- It helps in identifying the indices of the
Bounding boxes.
Take boxes():- It helps in identifying the values of the
indices of the Boundary boxes.
19. Functions (Contd….)
guessthesix():- It helps in determining the characters of the
number plate exactly.
readLetter():- It helps in displaying the alpha numeric
number from the input number plate.
Createtemplates():- It helps in comparing the extracted
characters from the number plate from the stored
templates.
20. Elements Of a Typical ANPR System
For implementing the ANPR System practically the following
hardware equipment are required:
Camera(s),
Illumination,
Interface Board,
Computer system,
Hardware,
Software, and
Database..
21. Typical Applications of ANPR System
The most essential need of present scenario is to control the
bottlenecks of Traffic jams, breaking of traffic rules by over
speedup the vehicle, etc., etc..
Thus to minimize these essential problems, this system is widely
used.
Other problems like parking system, toll tax payment system, etc.
all can also be manage by using this technology.
23. Applications (Contd…..)
Traffic Control System:- In this, the LPR system classifies the
cars on a congested entrance into 3 types (authorized, known
visitors, and unknown cars for inquiry) and guides them to the
appropriate lane. This system reduced the long waiting lines and
simplified the security officers work load.
Toll management:- In this , the plate is read when the vehicle
enters the toll lane and presents a pass card. The information of the
vehicle is retrieved from the database and compared against the
pass information. In case of fraud the operator is notified.
24. Advantages of ANPR System
The greatest advantage of using ANPR System is
that it can keep an image record of the vehicle
which is useful in order to fight against crime and
fraud.
Also, it makes everything automatic.
25. Limitations of ANPR System
It has some limitations too. They are:
It can recognizes only specified font (Times New
Roman) number plate only.
2. It can’t clearly recognize or distinguish character
like B and 8, 2 and Z, 0 and O etc.
3. The distance of image captured is also limited.
4. Lighting Conditions greatly affect the image
processing.
26. Limitations (Contd…)
It’s biggest limitation is that it can never be applicable in India.
In India, vehicles are foreseen with plate like structure in other
parts of the vehicle body, these plate like structures may be
misclassified as vehicle’ License plate.
It becomes a part of tradition to hang over conventional objects
near the plate position, which degrades the time and accuracy of
the LPR system.
