Introduction

1.1 General Introduction

            Siachen located in the eastern Karakoram range in the Himalaya Mountain at about 35^o 30'N77^o00'E /35.5^o N 77.0^oE, just east of the Line of control between INDIA-PAKISTAN. India control all of the Siachen Glacier itself, including all tributary glaciers. At 70 Km (43 mi) long, it is the longest glacier in the Karakoram and second-longest in the world's non-polar areas. It falls from altitude of  5,753 m (18,875 ft) above sea level at its head at Indiracol on the China border down to 3,620 m (11,875 ft) at its terminus.

            In the recent past, there has been a lot of interest in developing UGCs (Unmanned Gun control) to perform a variety of challenging tasks ranging from military defense, surveillance, etc. With the increasing processing speed of computers, automatic visual tracking systems have gotten more attention now-a-days. Now these systems are not only used in civilian areas but also in military and warship application. This project is focusing on shape detection to observe the real object image. This paper starts by describing the method of converting RGB image to binary signal using MATLAB. Then the binary signal is used as an input signal for the detection part. Correlation based template matching algorithm has been chosen for visual tracking as it is used in military applications of tracking and surveillance systems.

In the algorithm, tracking is started by selecting target of interest by the user. In the following frames, it is matched with all the candidates and best match is found. For sake of efficiency and real time implementation, the template is matched only within a search region instead of whole image frame. Morphological operators have been used for motion extraction of non-stationary object in the image frame. For motions extraction back-differencing and combination of morphological operators on the resultant image are used to extract connected components in image frame. This automated system is implemented using 8051 microcontroller which controls the stepper motor coupled .

This mechanism does not require any sensor or synchronization for tracking the object. The ground motor is fixed, while to control the other axis second motor is fixed on top of the ground motor. Hence the system utilizes two sets of independent control mechanisms, each operating in isolation for each axis. To accomplish this we propose a mechanism which will employ image processing in which webcam will be continuously observing the area under surveillance.

This data will be then processed by a MATLAB code which will be running on a PC and will be able to detect a particular color in front of a white background. Depending on this process data the information about the intruder location will be sent to a microcontroller (89c51) via the serial / parallel port of the PC and then motor control gun will be used to point in the direction of the intruder. With this mechanism will be online that is the gun will be continuously be pointing in the direction of the intruder. Further depending on range (distance from the gun) (fixed range in this project) the gun can be activated and a laser pointer will be switched ON to depict shooting the targets.

1.2 Motivation

            Going a step forward it is also required it is also required to safeguard the people who are guarding our boundaries and we need to take to take care of the issues that re faced by them. During the last Kargil war it was observed that the Pakistani military had occupied the India's vacated positions during winters in violation of the Simla Agreement. Every winter the military forces of both the countries (INDIA and PAKISTAN) vacate their positions in the Siachen and then re-occupy it when the snow melts as it becomes very difficult to survive in the cold. But for the first time in 52 years 'India Vacated Land' was occupied by Pakistan military on Pakistan's, then, Prime Minister Musharraf 's Orders.

1.3 Preface

            From ages it has been a desire of humans to achieve the ultimate in security and make his loved ones and loved things secure. It is this desire that prompted him to make the boundaries and secure them too from all unseen and unknown sources. For this it has been always necessary to maintain a huge sum of people to guard and raise alarms in cases of emergencies.

1.4 Objective

In this project we shall try to incorporate the following features :

v  Set up an automatic weaponry  mechanism.

v   To keep track of objects in a uncolored environment.

v   Fire upon in case it detects a specific color .

1.5 Features

v  Cost effective.

v   No complex hardware design is required.

v   Only MATLAB coding is used.

1.6 Scope of the project

v  It is used mainly in places like high altitude, cold region [-53^oC].

v   Mainly used in safeguarding boundaries.

v   During the War it can be fixed in helicopters for automatic detection and firing.
