1 INTRODUCTION

This software requirement specification report expresses a complete description about 3D Simulation and Management of Video Surveillance Systems, sponsored by 3K Information Technologies. This document includes features, functionalities, specifications and explanations about the project SURV3D which is a senior design project provided by Computer Engineering Department of Middle East Technical University.

1.1 Problem Definition

Nowadays security is becoming a major issue in many places like prisons, banks, military areas, public areas etc. In such kind of areas, security is mainly supplied by placing surveillance cameras around the place of interest, manually. But these cameras may have troubles during surveillance due to some blind spots that cannot be covered by the system. Another problem related with cameras is the fact that today there are hundreds of different types of cameras with hundreds of different features. This variation and evolution of cameras cause some inconsistency problems within the surveillance system.

Problems mentioned above take time and expense to be handled. Such problems may not be spotted until a dangerous circumstance happens in the critical area where strict surveillance is required. Therefore it is costly to design and maintain the security system using cameras manually.

Using a 3D simulation of the area to decide where to put cameras and manage them using software is a solution to the mentioned problem. With this project we can foreseeingly design where to put the cameras by trying out different points so that we can cover the subject area with minimum number of cameras.

1.2 Purpose

The purpose of this document is to present the details about SURV3D project and specify the requirements of it.

Preparation of this SRS will help all of the requirements before the design starts and reduce the time and cost for later redesign, recoding and retesting. The review of SRS can reveal omissions, misunderstandings, and inconsistencies early in the development cycle when these problems are easier to correct.

1.3 Document Convention

SURV3D will be designed and implemented corresponding (following) to these Software Requirement Specification document. So this document does have a substantially binding property for the whole project. Updates to be applied over this document are crucially important, because it will affect the process of the project.

1.4 Scope

This project is going to be used as a management infrastructure of concurrent video surveillance systems. Applying 3D simulation over the subject area that is intended to keep secure, system will help deciding where to put cameras and will create a solution to manage them using software. One can decide where to put cameras by trying out different coordinates so that number of cameras used to track intended area will be kept minimum. Moreover, system will make possible to ensure whether the place is secure using the views of cameras with human tracking abilities, motion detection etc. 3D video fusion method to enrich the visuality of software will also be used.

1.5.Fundamental Literature Survey

Market of surveillance systems includes a wide variety of items such as cameras, recording devices, network devices, software applications and professional services. This market is showing a rapid development in our country and in the world because of advancement in technology, diminishing prices of products and raising importance of security. So our point of motivation for carrying out this project is that increasing importance of security and lack of simulation systems for setting up well-designed, foreseen surveillance structures before investment step in the market.

1.6.Target Audience

This document is targeting the audience that ones who will analyze project’s functions and can make changes over the project in design and implementation process. Software requirement specification will also have an guideline composition for being able to set milestones during project implementation. In addition, tester candidates can refer to this document for developing testing strategies throughout the testing phases and end users can read the document for understanding the capabilities and facilities of project.

2.Overall Description

2.1 Product Perspective

SURV3D application is totally independent system that is not related to any other system and not a component of a larger system. This program has two types of users: admin and observer. The application welcomes the user with a login screen from which the type of user can be selected. A user can login to the system by entering his/her password and username. After logging into the system admin is faced with a screen from which the admin can create the environment to be secured. While creating the environment, first admin must provide the required DTED map data files, name the environment and make some technical adjustments about the rendering of the environment. After creation phase, the admin will continue to make adjustments to complete the surveillance system by importing 3D building models, adding cameras and calibrating and managing them. Coming to the observer, after logged into the system an observer is faced with a screen enabling him/her to choose the environment to be loaded which s/he wants to observe. After the loading process of the environment, an

observer can obtain stream from a camera, manage the cameras by changing the angle of cameras, navigate in the environment or activate/deactivate human tracking option.

2.1.2 System Interface

First of all the application needs to have a DTED map about the area to be observed. It must be loaded by an admin to render the environment. Therefore DTED maps will be accessible by only admins not by observers.

2.1.3 Software Interface

In order to use SURV3D properly, one should have a computer on which Windows Vista OS or a higher version must be loaded. In addition, Microsoft Visual C++ 2005 Redistributable or a higher must be loaded.

2.2 Product Features

Project will cover following features:

*Creating simulated virtual indoor images using DTED or 3DS projections of buildings

*Creating simulated virtual outdoor images using digital maps of environment which have elevation data of that places

*Analyzing vision ranges of placed cameras on given coordinates

*Algorithm development for motion detection during surveillance process

*Concurrent recording of different hardware video sources using IP network infrastructure

*Utilization of 3D Video Fusion for enriching the images created by system.

3. Specific RequirementsThis section will describe the software requirements in detail as subsections

which are interface requirements, functional and non-functional requirements.

3.1. Interface Requirements Product will have a graphical user interface which facilitates user’s utilization of program.

GUI will mainly have four screens as follows;

Authentication (Login ) Screen

Trying to use the system, users will be demanded to get authorized from the system. In order to display the interface corresponding to his/her role user role and properties, users must be authenticated from the system. In this screen user will write his/her user name and password then login the system. Depending on the user type next phase will be decided.

Admin screen

If the user has admin authentication, user will see this screen. In this interface admin

can add new observers and decide on their authentication. Also, 3D environment can

be created in the screen. Moreover, 3D models can be added on this screen. After the

3D world creation finishes admin can choose camera types and add these cameras to

3D world to set up view frustum. When all the executed operations are done admin

can save the session and logout.

Observer screen

If the user has observer authentication, user will see this screen. In this interface

observer first loads a 3D world. Observer can navigate in the 3D world freely and

change camera perspectives while viewing the environment with fused video from

cameras. Also observer can toggle human tracking feature and can detect human

intrusion to the system.

3.2. Functional requirementsIn this section, we will explain the major functions of the SURV3D.

Log in

User login the system using login screen. According to authentication of the user program

guide the user.

Create 3D World

Admin will create the world using DTED map and arrange this 3D world using 3D models.

Inputs for this function are DTED formatted elevation map and texture map. The outputs for

this function are tile sets of merged elevation and texture data and ini file for these datas.

After the 3D world creation finishes admin can add cameras to the 3D environment and

change the view frustum of the camera according to camera parameters. When system design

finished by admin , he/she can save the session and logout.

Load 3D World

If the user has observer authentication he/she can load 3D world models created by admin.

Input for this function will be provided by observer by browsing through hard disc. When the

observer loads the 3D world, this can be visualized by software.

Video Fusion

When the observer finished the 3D visualization he/she has capability of running 3D video

fusion on live video streams of IP cameras and 3D world information. Inputs for this function

are video streams coming from IP cameras and information gathered by clicked camera.

Output for this function is 3D video fused data and can be visualized on the observer screen.

Toggle Human Tracking

If the observer toggles the human tracking feature, software can detect the human intrusions

to the system and is capable of tracking the moving target.

3.3. Non-functional RequirementsNon-functional requirements will be examined in terms of design constraints.

3.3.1.Design ConstraintsLanguage:

The software will be designed on C++ using Visual Studio 2010 on Windows operating

system.

Map processing:

To handle elevation information from DTED maps system will use C++ language supporting

GDAL. Also, for 3D map visualization we will use libmini library.

Visuality:

OSG will be used for visualization.

Software System Attributes:

Reliability

-The system should provide reliable results over the map.

4.BEHAVIORAL MODEL AND DESCRIPTIONThis section presents a description of the behavior of the software.

4.1 BEHAVIORAL DESCRIPTION OF THE MODELWhen the program starts, at first, user will see a login screen. In this screen user will required

to provide username and password. If the information is valid the user will be able to move on

with the program. There are two types of user roles. One of them is “Admin” and the other

one is “Observer”. Next screen will depend on the type of the user. Admin will view a screen

where he/she can add new user, create 3D world using DTED formatted maps and make

modifications on the created world. Modifications may be adding new objects or adding new

cameras. Also added cameras can be modified. These include setting camera types, analyzing

their view frustum and changing camera perspective. At last admin will save this modified 3D

world. After the admin has completed every task he has been working on, admin can log off

and get to the final state. The next screen, which is after the log in screen, for observer will

make observer to choose a 3D world which is saved by the admin. In the loaded 3D world

observer can be able to change camera perspective and navigate in the 3D environment. Also

in the 3D world observer can get live video from IP cameras. Moreover observer can see

fused video stream from IP cameras in matching parts of the 3D world, which is 3D video

fusion, by clicking on a desired camera. In the videos human tracking can be toggled by the

observer. For instance if no one is expected to be in the area where a certain camera is

viewing, then in that camera’s viewing frustum, human tracking feature can be toggled on. In

case something needs to be taken care of in the same area, for instance a technical issue or

repair etc., human tracking can be toggled off. Whenever someone is detected in a camera

where human tracking is active, 3D video fusion for that camera will be carried out

automatically by the program to show it to the observer. At last whenever user logs off from

the system, it will end to its final state.

4.2 BEHAVIORAL MODEL OF THE SYSTEM

5 Planning

In this part of the SRS, structure of the conducting team, fundamental schedule, and the process model are included.

5.1.Team structure

This team’s members have created a football team to join CENGCUP two years ago, so that coordination and communication between team members are gone in a proper and expected attitude. Each team member’s opinion through the project is considered crucially important, so that democratic non- hierarchic structure of team is ensured. Our aim is to provide equivalent workload distribution between team members, and we are successful in doing so until now.

Our team has assigned Cihan as the communication staff, so official mailings and assignment of team meetings are set by Cihan.

Members main roles are as follows;

Cihan: The communicator, Team Leader, the devil’s advocate , the announcer

Emirhan: The optimist, the harmonizer, the encourager, the summarizer

Ziya: the information seeker, the gate keeper, the devil’s advocate

Andaç: The recorder, the devil’s advocate, the initiator, the optimist
