8 Tips for Buying Your Drone

drone-520x245Businesses and consumers alike are finding new ways to use drone every day. From real estate to event photography to sports, drones are being used for a number of purposes. On top of that, people are finding drones to be a great past time activity too. This is the reason why there has been a spike in the demand of the drones and people all over the world are looking to buy one. However, buying a drone isn’t a piece of cake. There are a number of aspects that you need to keep in mind before you go into the market to buy one. The following are some tips that are going to help you in buying a drone that is fit for your needs. The following areas should be examined prior to purchasing a drone.

Purpose of Use

The first tip for buying a drone is to identify the purpose for which you want this vehicle. For instance, if you are looking to get this device for purely recreational purposes then even a small and cheap quadcopter would be enough. However, if you want to buy the drone for professional aerial photography and videography then you will have to go for a more advanced model that is capable of capturing photos at different angles. For cargo carrying requirements, you will require a drone that is capable of lifting heavy loads and carrying them over long distance. If you plan on buying the drone for inspection purposes then it would be best for you to opt for a drone that can function in unfavorable conditions. Drones used for wildlife photography are usually quite expensive and should only be bought if you are a wildlife photographer who wants to capture the wild animals in their natural habitat without risking yourself.

Machinery

Another of the aspect that needs to be considered when it comes to buying drones is that of its machinery. There are various types of drones available in the market but they have their own respective mechanisms. You have to understand that not all drones have the machinery available to perform the functions that you want them to do. For instance, if you want to get the drone simply for the fun then a quadcopter with simple machinery would be just fine. However, if you plan on using the drone for a commercial purpose then the quadcopter would not be enough. You will then have to go for a drone whose machinery is capable enough to complete the task be it photography or package delivery.

Design

Another tip that might come in handy when you are buying a drone is to have a close look at its design. Generally all the UAVs have the same basic idea; they fly without the need of an on-board human pilot. However, they differ on the basis of their design. For instance, the quadcopter has four motors to propel it and look almost like a helicopter while the military grade drones are jet fueled and look more or less the same as usual airplanes. So, unless you are in the military and are in need of a stealth drone, it would be best for you to go for a drone that has a simple design.

Camera and Gimbal Supports

Drones are mostly being used for the purpose of photography and videography. If you want to use yours for the same purpose then you will have to find one that has a camera installed on it. However, an ordinary camera won’t do the job. You would have to make sure that the camera mounted on the drone you are buying is a good one that can take high quality pictures with ease. Another tip to keep in mind is to buy drone that has a gimbal support. The gimbal support is going to keep the camera stable during the drone’s flight, allowing it to take better photos and videos.

Battery Time

Battery timing is of great importance too when it comes to buying UAVs. Generally, a quadcopter or drone will fly for around 5 to 15 minutes at a stretch. With a bigger battery, the drone can stay airborne for more than an hour. So, it is best that you go for a drone that has a powerful battery especially if you want to use it for aerial photography or inspection purposes. Make sure that the battery of the drone is rechargeable and can be quickly powered up.

Range

The range of most of the drones is not more than 50 meters. This is generally a suitable distance for taking aerial shots. However, there are advanced drones available too that have a much higher range. If you want the drone for wildlife photography, then it is best that you go for one that can provide you with a range close to 100 meters or more.

Spare Parts

Always ask the dealer to provide you with spare parts for your drone. Most of the drones available in the market come with spare rotors as these parts of the drone are fragile and can breakdown if consistently used.

Cost

The price of the drones is dependent on their type. If you want to buy the most basic model then you won’t have to spend a great deal of money on them. Still, it would be a considerable investment as these aerial vehicles don’t come cheap. You can get the drone for a lower price if you look for them on the internet. There are many websites that provide discounts on the sale of quadcopters.

In closing, there are a number of aspects that you need to keep in mind before you go into the market to buy drone. If you take these considerations in mind you will get the most out of your investment.

Important Tips To Improve Photogrammetry Scanning Quality

pixel-light-effects-rig-for-services-2Photogrammetry can simply be defined as the measurement of photographs. It is a process that largely depends on camera positioning around the given subject and light control to create high resolution details of skin and clothing. The scanning can be used for capturing data for various projects including face replacements and CG characters. With so many variables to control, photogrammetry scanning can be overwhelming. There is just too much trial and errors involved to achieve best practices but with a few helpful tips, it is very possible to achieve accuracy and top quality with the process.

Tip 1 – Think about overlapping coverage. When building your setup, you should use as many cameras as possible so you are able to reduce or minimize manual cleanup later. Enough coverage translates into very decent recreation and you will also rarely miss any information when you use enough cameras so manual cleanup is very minimal.

Tip 2 – Put in measures to minimize distortions. When there are distortions, it is given that your system will have issues aligning the images. The fact is that most Photogrammetry systems come with a lens that helps reduce images, but it is always a much better choice to try and minimize it in-camera. Use tools that match with the camera format that you are using to get the best results every time.

Tip 3 – Mask out the background to dramatically improve overall quality of generated mesh and post processing time. It is a process that can be time consuming, especially when you need to go through every single picture but it pays off in the end. If manual masking is something you would rather avoid, then you can use systems that offer automatic masking feature to achieve a clean background. It also helps to tie cables together and eliminating any junk from the frame, especially when using a camera rig.

Tip 4 – Focus on more resolution when operating. You can use as much as necessary from your sensor because the more the resolution you can achieve then the more detailed your mesh is going to be. Try every way not to waste a single pixel if you can actually use it for quality benefits.

Tip 5 – Remember that lighting remains key in all kinds of photography. To increase depth of filed and eliminate photo noise, keep your aperture small and ISO as low as you can. But because doing so will definitely decrease amount of light that you get to work with, ensure that you have other light sources to substitute. Consider using flashes over continuous lighting that are less efficient, less color accurate and expensive for that matter. Flashes keep talent comfortable and enough lit unlike continuous lights that can produce heat leaving enclosed rig hot.

Tip 6 – Pay attention to photo orientation. It is factor that plays a huge role in accuracy of projects and it needs to be accurate for every camera position. Increase number of well-positioned points to improve orientation quality. These points should take up a greater percentage of photograph area.

Photogrammetry is among the services that you can enjoy from 3D scanning experts. Choose a service provider you can trust to deliver quality to your photo project, however demanding it could be.

4 Myths About Fiber Optic Cables

While fiber optic cables have been around for a long time, most people don’t fully understand them. Due to this, there are plenty of myths surrounding them. Some of the most common myths include:

The optic fibers are expensive

Years ago, the fibers used to be expensive. They were more expensive than copper. This is no longer the case. Nowadays, due to the drop in the manufacturing costs and ease of terminations, fiber optics are now less expensive than most of the copper installations. In addition to the cables being cheap, they are also easy to maintain.

The cables are difficult to terminate

Just as the fiber cables were expensive a few years ago, they were also difficult to terminate. The cables were fragile, they required you to limit the amount of exposed glass, and the glass shards were dangerous thus you had to take great care of yourself. With advances in technology, this is no longer the case. Nowadays terminating the fibers with SSF is very easy. In fact, you can do it with just a little training.

The fiber optic is impossible to hack

Fiber optic cables are often used in computer connections. One of the most sensitive issues with computer connections is the ability of other people to get access to your information through hacking. The cables use light that stays within the cables which makes it difficult for hackers to access your data. While this is the case, it doesn’t mean that it’s impossible for hackers to access your information. All the hackers need to do is to have a network tap and a physical access to your cable. Due to this risk, you should take the safety of your computers seriously to prevent people from getting into your network. You should also encrypt any data that you want to be kept private.

Optic fiber infrastructure is different from that in copper

In most cases, fiber optics are compared to copper. Since they are competitors, many people feel that their infrastructure is different. This isn’t the case. Most of the parts and pieces of the two are similar. The wall boxes, patch cables, wall plates, and in-wall components are the same. The layout of the two networks is also similar.

Conclusion

If you didn’t know some inside details about optic cables now you know. For the units to give you ideal results you need to buy them from a reputable store.

Advantages of Renting a Drone Versus Buying One

We’re living in a technological boom where every day we’re learning about a new development. Sometimes you encounter a new technology which is more sophisticated and helps you get your work done faster and/or more efficiently. Technology is becoming more so as it is shown in the tech savvy fiction films where the machines have their own brains. Drones are a modern marvel that have impressed not only the military, but have also captured the imagination of the common people too.

There are many people who would like to buy a drone for themselves but these aerial vehicles come at a premium price. This is why you have to weigh various pros and cons before you get to the stage of buying a drone. You may like to have a reception party and capture those precious moments at angles and heights that look amazing. If you have money to spend then you could buy a drone for your personal usage. However, like most people, if your spending budget is low then it is better to rent a drone instead.

There are various companies in the market that offer drone rentals. When it comes to deciding upon buying or renting the drone, you must consider the pros and cons of both.

Usage

Drones are anticipated to have a wide variety of uses in the future but for now the use of drones is mostly used for photography, while few are using them for surveillance, inspections and survey and mapping purposes. So, if you are not a professional photographer who needs to use a drone frequently, you probably don’t need to buy it. Simply renting the drone would be an ideal fit for you as it would allow you to use the drone when you have a need for it and then return it back when it has served its purpose.

Flying the Drone

Flying the drone is a major issue when deciding whether to buy or rent the drone. If you decide to buy the drone then you will have to learn about how to fly it too or it will not serve its purpose. However, renting the drone would spare you from having to learn anything about drone flying. The companies who rent these aerial vehicles will provide a pilot for you that will take over the flying duties. You would just have to tell the pilot what to do and he would deal with the rest.

Licensing Issues

Drones are aerial vehicles and thus require proper licensing before they can be used or flown in the air. Obtaining a license for a drone can be a very time consuming process. The companies renting the drone however have the required licenses and necessary paperwork for their equipment. So, you don’t have to worry about the licensing one bit. You just pay the rent of the drone and can then use it freely.

Cost

The cost of the drone is a major factor to consider when buying it. If you do not want to indulge in drone racing or other drone sports then there is no point in buying this equipment as it will just sit in one corner of the house. Drone rentals on the other hand are a great option for all purposes. If you want to learn about flying a drone or just want to have a little fun with it then a rented drone could accomplish this without requiring you to spend big bucks. Thereafter if you feel that it is worth the purchase then you can buy the drone of your choice.

Purposes for Renting Drones

Drones can be rented for various purposes such as:

· If you are hiking and you want your photos and videos to be made from far then drones can be of help. Also if you want to take pictures of the high mountains and rugged terrains or just have a look at what is on the other end of a high peak, then drones are the only option you have.

· If you are planning on selling your house or property you will need to send good photos of your property to the contractor. With the help of a drone you can take endless pictures of the roof, the chimney, or the windows from any angle without the need for a ladder.

· Drones can even be used to keep an eye on your farm by giving you the bird’s eye view of your land

· Drones can be rented to go for vacation where you can make aerial view videos of your own or you could just use the drone for the purpose of sightseeing.

· Drones can be used for sports photography as well.

Taking Care of Rented Drones

When you rent a drone, you must take care of the following things:

· The date you have fixed for your event or vacation is not a feasible one for the renting company so you must keep your dates and time flexible as this will ensure that you have photographs done the way you want them to be. Also, it is better to get the photography done in the mornings and evenings as this is the time when the sun is best for photography.

· You must know what kinds of shots you want. You should have a look at the similar projects online and make sure that you tell the photographer about the same.

· While taking photographs with a drone you must not forget to first make sure that the place is safe for flying with drone. You must not have trees and buildings as obstacles and neither should you fly them over people. Use common sense to make sure everybody on the ground is safe.

· You must be aware that the drones are of different qualities and that is going to affect the quality of your videos and photos. The DJI Phantoms are the cheapest, most available and most used drones, but for high end picture quality you will need the professional model or a high quality camera and that is going to cost you more.

· Also, it is important that you get the enhancements and corrections done in the photographs, because raw pictures and videos usually need editing.

Tips on Making Distributed Agile Teams Successful

Tips on Making Distributed Agile Successful

Purists and Scrum hipsters will argue that dispersed teams are a taboo in Agile communities of practice. However, in reality there are many instances where an organization has to outsource due to lack of local skill set or other reasons. Being prepared for what to expect and how to approach and prepare for the facilitation of distributed teams can go a long way in ensuring the success of the Agile initiative.

1. Decide on how to distribute

  • Teams work differently in their remote locations, but the whole team officially syncs up at least once a day, but also ad-hoc as situations call for it;
  • ach team in each location has all the necessary skills to execute on the committed sprint backlog;
  • Individuals in different cities must be encouraged to work as one team as opposed to one team in country A and another in country B;

2. Create stickiness or coherence

  • We want teams that will stick together which requires a clear vision;
  • We therefore acknowledge that cultures in our team differ – we should encourage collaboration and relationship nurturing early on in the project for sub-cultures to form;
  • Work actively to strengthen tactical as well as team structures;
  • Build trust through early communication of progress

3. You’re going to have to change how you communicate

  • In the Cinderella Project (a perfect project) a team would come together from their disparate locations to meet, socialize and form cohesion;
  • We encourage teams to stay together for at least an iteration;
  • Learn the lay of the land
  • Become familiar with the ‘flavour of Agile’ being used (e.g. all teams estimate, collaborate, execute and communicate differently – get to know these traits – it’s going to make or break your Agile initiative!)
  • Organize quarterly visits for either the whole team or have people cross pollinate through travelling between locations
  • Invest in the concept of having team ambassadors, people that ensure good working relationships
  • A Wiki culture, or information sharing philosophy is going to be very important, more so than with co-located teams
  • You are going to need more meat on that product backlog to physical counter the absence of key people
  • Horizontal communication must be encouraged and drive
  • Distance isn’t such a problem, time zones are!

When transitioning to a distributed team, err on the side of over-communicating.

4. Additions you’d need to accommodate in the framework you are using:

  • Meetings will require slack time, people are going to catch up (and rightfully so) whether you like it or not;
  • Share news as it happens about the project, good and bad
  • Honour basic meeting etiquette:
  • One conversation at a time
  • Everyone must know who is speaking
  • Keep to the time-boxes
  • Facilitator to set up technology, conference bridge etc. in advance of meeting, and test the connections
  • Ensures everyone has the right dial-in information

5. Technology

  • You’ll have to ensure your technology supports your dispersed nature
  • Use Agile Lifecycle Management tools like Jira, VersionOne etc
  • Use proper high quality video and voice tools to video-conference successfully and to bridge the distance gap
  • Online whiteboards for design sessions will aid collaboration
  • An online Retrospective tool that will ensure the opportunity to improve isn’t lost
