Everything you Need to Know about SLAM




SLAM is short for Simultaneous Localization and Mapping.   For autonomous vehicles that allow you to build a map and then locate your car on it simultaneously, this method is ideal. The algorithms make the vehicle possible so that areas unfamiliar to it can be mapped out. In addition to this, engineers use the map data to perform various tasks such as obstacle avoidance and route planning. To find out more, read on.

Why SLAM Is Relevant

SLAM has been used to do technical analysis for many years. However since the speed of computer processing has increased exponentially and low-cost sensors have been made available, SLAM is used in various fields for a variety of practical applications.

Examples for SLAM

A robot vacuum is an instance of a SLAM. The robot vacuum can move around arbitrarily in the absence of SLAM. As a consequence, the whole room will not be swept. In addition, this strategy will consume much more power and the battery will run out much faster.

SLAM-based robots, on the other hand, can allow the vacuum to work better. This technology actually uses technological knowledge, such as the number of revolutions that come from sensors and cameras for imaging. This is referred to as localization and prevents the computer from moving twice through the same location.

In other fields of use such as parking a car and navigating mobile robots, SLAM is very useful, just to name a few.

How SLAM Works

Monocular: SLAM

Generally, for this technology, two types of components are used. The first type is known as the processing of sensor signals, which requires numerous processing types.

This technology involves optimizing the pose graph, which involves processing the back end.

Visual SLAM

Visual SLAM is referred to as vSLAM, too. It makes use of images and cameras from image sensors. This means basic cameras, such as spherical cameras, wide-angle cameras, and fish-eye cameras, just to name a few.

Without investing a lot of money, the best thing about visual SLAM is that it can be applied. Besides, you can use them to detect landmarks since cameras give a lot of information. Combining landmark detection with graph-based optimization is possible.

Monocular SLAM refers to a device in which only one camera is used. Depth, which can be resolved by detecting AR markers and checkerboards, is therefore difficult to define.

This technology involves optimizing the pose graph, which involves processing the back end.

SLAM’s advent

In 1995, at the International Symposium on Robotics Science, SLAM was presented for the first time. At the IEEE Robotics and Automation Conference, a mathematical description was given in 1986. Studies were carried out after the conference in order to find out more about navigation devices and statistical hypotheses.

Experts implemented a system to incorporate one camera after more than a decade to accomplish the same goal instead of using several sensors. As a consequence, these attempts led to the development of SLAM based on vision. In order to get a three-dimensional location, this scheme used cameras.

This was a great accomplishment of that period, without any doubt. We have seen the implementation of these systems in a variety of areas since then.

The SLAM Core, Mapping, and Localization

Now let’s find out more about SLAM systems mapping, localization, and the core. This will help you learn more about this technology and have a better understanding of how effective it has been proved.


Localization will assist you in deciding where you are. Basically, on the basis of visual details, SLAM gives you an estimate of the spot. It is like when for the first time, you come across a mysterious place.

We can get lost because we humans do not have a good sense of safety and distance. With regard to the surrounding area, the best thing about SLAM-based robots is that they can quickly find out the way. It is critical, however, that the map should be highly trained to detect your position.


Mapping refers to a tool that helps to analyze information gathered from a sensor by the robot. Vision-based systems typically make use of cameras as sensitive sensors. Triangulation techniques are implemented to obtain a three-dimensional position after the production of adequate motion parallax in two-dimensional locations.

The beauty of augmented reality is that in a real world, it can help collect data from virtual images. In order to understand the world around it and spot the relative location of cameras, however, augmented reality requires some technologies.

So in a variety of areas, such as position interaction, gui, graphics, display, and tracking, you can see that SLAM plays a very important role.



This was an introduction to slam and its characteristics, long story short. Hopefully, this article will allow you to get a deeper understanding of the method and the areas in which vehicles and other devices are employed for better performance.

Hacking – A Fullstop On E-system




Hacking – A Fullstop On E-system

Passion or Madness: Now days, it has become a passion to learn how to hack. Some of us do it for the sheer challenge, some for the sheer love for learning and new technologies. Regardless of what the reason is, with every hack someone is trying to improve the technology we rely on.

There are many hacking related skills one can learn, depending on the person and the type of hacking they want to do. As there are many opportunities and facets to the hacking world, it makes it complex to learn all things related to it.

But, it is never too late if you have the right information and the right techniques. In order to make sure that you have all the information you need, you can always study and learn hacking. The best part of it all is that, for all you know, you can be the next hacker that redefines the way we think about security.

Mentoring: There are many opportunities available for collaboration and snooping on hackers. If you have an interest in snooping on hackers or have the opportunity to learn from them, consider taking a class or participating in a workshops. You might be surprised how much knowledge they have about the technologies they use… and you can use what you’ve learned and put it to good use.

Sniffer: We have tools now that can let us track IP addresses. We can also tell how far away the IP address is from us, and we can sniff for firewalls, viruses, and other threats. We can also reveal a lot of other information about the person/company that we are dealing with.

Cache: We refer to the temporary files that store all the information that has been fetched over the net. Actually, the term ‘cache’ is a bit misleading. The information is not stored in order and there is no order to it. The information is usually stored in memory and while it is loading it is also stored in a temporary location so that it is not immediately discarded. The temporary location is emptied when the request for the information is finished and then the information is discarded.

Many hacking tools use a variety of modes of communication Protocols (Speakers, Morse code, Direct Sensing, etc.)


•http which is a general term used for HTTP/ActiveX and often used by many InternetBrowsers, presents significant security risks. It is a specification supported by the Internet Engineering Task Force (IETF) and is responsible for the functioning of the World Wide Web. The primary concern of the IETF is the transfer of files and processes over the Internet.

The subsequent technologies, which are often but not always classified, follow between HTTP and TCP/IP and SPI.

Internet Protocol (IP)

•IP over SSL

• Internet Protocol (IP) is a set of protocols that offers Internet users the ability to communicate online using the TCP network. The IP protocol applies resource sharing and addressing methods among the computers on a network and is responsible for the flow of information exchanged during online transactions. Online users consists of computers that have been granted access by an Internet service provider (ISP).

Online Systems Management (OSMP)



o Virus Bulletin No. 9110 provides updates on viruses that are specific to the Microsoft IIS 5.0 Extended Validation SSL Certificate. This Microsoft SSL certificate enables you to secure private data that pass through, including documents, e-mail messages, and on to databases, which store user credentials and other private information. This certificate also enables your site to display a secured page now and later, when your users click a protected link.

The CSR data must be verified and properly transformed in the digital object before it can be authenticated and then encrypted. Therefore, to access the signed certificate, the user must have the Bit-Authentication turned on for the Microsoft Exchange 2007 Online Explorer (E), which comes with the SSL functionality.

Effects of Certificate Fraud

A fraudulent Certificate could cause several problems for the user. The certificate could be fraudulent in the sense that the name of the sender or any essential part of the signature block is misrepresented or false. Physical inspection of the AIA may also be performed by an authorized third party, such as an auditor, in order to confirm the fact that the web site is legitimate. If SSL authentication is possible and has been enabled on the site, the browser will display a padlock and indicate that an SSL certificate is secured.

Reasons to Prevent Certificate Fraud

The instances of certificate fraud may be reduced if users and businesses implement evolving strategies and are informed about how the security process & monitoring mechanisms work.

How To Avoid Spyware Before It’s Too Late!




How To Avoid Spyware Before It’s Too Late!

Unfortunately, most people don’t pay much attention to the threat posed by spyware until their level of infection has become acute and their private information has been compromised. The final result is that they become subject to an identity theft attempt. New methods of attack are being developed all the time and you need to get up to speed on the subject and stay informed of changes as they occur in order to know how to protect yourself.

First of all, if you are a careless surfer you are living dangerously and eventually you will get nailed. The smart thing is to set your computer environment up with a secure defensive perimeter and to prevent unauthorized access to your computer and check out any personal information that you have stored on your hard disk. If you surf the web, open attachments or use peer to peer applications then you risk being victimized.

The statistics are staggering and reveal just some of the tremendous amount of personal information that is present across the internet. According to requirements imposed by the federal government, we can all be traced back to our IP address. With that information in the wrong hands, a lot of people have a lot of problems.

The only solution is to minimize your risk of exposure. This requires you to be careful about the type of information that you divulge while online. Don’t assume that you can just offload your personal information to sites that are willing to accept financial information. Sites that are willing to acquire your information will have an address that you can contact them to confirm their legitimacy.

Other risk factors include file sharing programs, so you should download and install programs like the well-known P2P file sharing programs like BeXTRA or CoolWebSearch that help you keep your computer free from harmful viruses, hackers and worms. Surfing anonymously will also help keep your privacy since no one will be able to trace you and your actions.

Why should you risk it?

Secure surfing is one of the best ways to protect your identity and personal information. It’s not hard to understand why most people begin to take a liking to the idea and begin to make regular trips to the local library to surf the internet and download files. The truth is that they should avoid these activities because it is possible that they are the victims of online thieves.

The trailblazing technology of today has helped to make the whole process much safer and understanding students to use the internet and avoid harmful viruses. However, these efforts have not been able to totally rid the internet of its infamous reputation as a source of crimes and victim of fraud. Users that have criminal intent will never be able to track you using your IP address because mobile malware and other malicious programs will also be unable to track you.

Using this technology will also help you to stay protected since you will be able to encrypt your data which will render it totally unrecoverable once it is deleted from your computer. There are numerous applications available when it comes to protecting yourself from cyber crimes; one of which that is available is the IP hiding software. This software enables you to surf the web undetected through the IP address of origin. After the IP address is hidden, the site you visit will pretend to be from the computer you are using.

This is because the site is actually acting as a proxy server; one that originates from the computer you are using. If you are currently using a site that you are not sure of, then visit a local library or search online for a few reviews about the product.
