    Best camera drones in India 2021

    DGCA  lifted the long running blanket ban on drones back in 2018 making the use of drone cameras legal in India.

    Drones have become far more than just simple aerial toys that they used to be. Drone cameras allow professional photography and videography of landscapes, buildings and unreachable places which can only be done before with the help of a helicopter or a hefty big crane!

    The Indian government and the drone flying community have had a tense relationship ever since the ban was lifted.But drone flying is still prevalent and ever growing among the Indian crowd.

    Drones are a great investment for budding or professional  photo and videographers as it’s a no brainer that a drone camera is a must if you want to add production value to your photography or videography by adding scenic aerial shots.

    But those scenic aerial shots have a hefty price tag, you get what you paid for. If you want to invest in a good drone that can capture stunning footage you need to be ready to spend some serious cash. So research is must before buying a drone.

    Even though the market is dominated by DJI drones there are a few underdogs that are trying to make it big  in the Indian market. We at techoids have curated a list of the best drones that you can buy in India to help you narrow down your search for your perfect match!

     

    What to look for while buying a drone

     

    GPS

    According to the DGCA, GPS is a mandatory feature to have for flying drones in India.

    The positioning system helps the drone to keep its position stable, you don’t want your drone to be flowing with the breeze!

    It not only helps in stabilizing drones position but it also enables automatic return to the take off point if the drone loses control or if the battery is on the verge of dying.

     

    Controller

    Most of the controllers work by sending a radio signal to the drone, which tells the drone what to do.

    Some of the lower standard controllers use Wi-Fi to send the signals to the drone, these controllers usually have poor range (around 100m). Some drones might also use a smartphone as a controller. A good controller range is important if you want better accessibility.

     

    Camera & gimbal

    If you are just getting into flying drones, a drone camera close to 2MP would be able to shoot decent photos and videos. But professionals who want high quality footage can go for 1080p HD or 4k quality cameras as well.

    Some high standard drones often come with stabilization features such as gimbals. even though the inclusion of a gimbal ramps the drone’s price up the smooth high quality footage that you get  pays it all off!

     

    Battery

    Drones can have either rechargeable or replaceable batteries. If you want to fly your drone for a long periods of time, look for drones with interchangeable batteries. Swapping batteries with spare ones will allow you to take another go at capturing that perfect shot!

     

    The App

    Some of the drones might use a smartphone as a controller. The apps that come bundled with the drone will have virtual buttons and various different features to control and monitor your drone.

    Before investing into a drone that uses a smartphone controller, it’s better to check the usability of the app. Ending up with an app with bad UI and usability would significantly hinder your flying experience.

     

    Flight time

    Flight time of your drone mainly depends upon the battery and the type of your drone (nano, micro). Usually flight times range from 8-30 minutes.

    Most of the nano drones will have 8-12 minutes of flight time while micro drones can have 30+ minutes of flight time.

    It’s crucial to choose a drone with a decent flight time as it affects the quality and length of the footage that you will be capturing.

     

    Type

    According to the standards of DGCA drones in India are classified according to their weight. Some of the drone types that are available in the market are nano, micro, small, medium and large drones.

    To fly a drone in India all drones except nano ones require permission. So when you are buying a drone look out for its type!

     

    Here’s the list of drones that we recommend!

    What is NPNT?

    No permission, no takeoff (NPNT) is a software program that allows every drone (except nano drones) to get permission from the Digital Sky Platform before every flight in India. It is mandatory to obtain permission before every flight, if not taken the drone will simply not fly.

     

    What are the mandatory features that a drone should have in India?

    All drones (except nano) should have GPS, return to home(RTH) feature, Anti collision light, ID plate, a controller with flight data logging capabilities.

     

    Rules that you need to follow while flying drones in India.

    According to the Ministry of civil aviation, flying a drone is legal in India. After DGCA (Directorate general of civil aviation) lifted the ban on drones back in 2018 CAR (Civil Aviation Requirements) for drones was formed which came into effect on December 1,2018.

    Drones in India are categorized according to their weight:

    • Nano: Less than or equal to 250 grams
    • Micro: From 250 grams (.55 pounds) to 2kg
    • Small: From 2kg (4.4 pounds) to 25kg
    • Medium: From 25kg (55 pounds) to 150kg
    • Large: Greater than 150kg

    Nano drones require no registration while all the others need to get registered from DGCA after which they will obtain their unique identification number(UIN) for their drone.

    Registered drones need to take permission from India’s digital sky platform before every single flight. This is being called India’s “No permission, No takeoff” (NPNT) system. If a pilot tries to fly his/her drone without taking permission they will simply not be able to take off.

    Users who own a small, medium or a large drone need a pilot license to fly the drone in India. Anyone who is 18 years of age and has passed 10th grade can obtain this license. The pilots will have to go for a mandatory 35 hours of training to obtain this license. Information about how to register as a pilot can be found here.

    Foreigners are currently not allowed to fly drones in India. Although they can turn their drone to an indian personnel who can then obtain a unique identification number from the DGCA.

    Drones can be flown as long as they are within the visual limits of the pilot and are flown outside the “No fly zones”. These no fly zones include airports, international borders and government buildings.

    These are the mandatory features that a drone flown in India should have:

    • GPS
    • ID plate
    • Controller with flight data logging feature
    • Anti collision light

    TLDR:

    • Registration and UIN (Unique identification number) are necessary for every drone except the nano category.
    • No drone should surpass the limit of 400 feet vertically.
    • Drones should be in the limits of the pilot’s line of vision.
    • Flying drones is restricted in the “No fly zone”, these zones include airports, government buildings and international borders.
    • Permission from digital sky platform is necessary before every flight.
    • Registration of pilots with small, medium and large drone is mandatory.

    More information on rules and regulations of flying drones in India can be found on the DGCA website.

     

    Conclusion

    DJI drones are currently dominating the Indian market. Due to the recent legalization of drones in India, the drone market is fairly new. So if you want to invest in a drone right now go for DJI drones.

    The coming years might prove important for the industry as we are seeing new companies taking chances and diving into the ever growing Indian market.

  • Transform your face in a photo into a 3d image

    Transform your face in a photo into a 3d image

    Transforming 2D images into 3D models will always have limitations. After all, we are deforming textures and altering other aspects of the original image, but if you want to do your own experiments without installing additional software or spend hours assimilating tutorials, 3dthis.com portal has a very interesting tool called 3D Face. Load a photo with the face facing the camera, adjust the automatic detection, and explore the results.

    Many photos have impressive quality, but no matter how clever the person in charge of the shot, depth is one of the first things that are lost, especially when using basic equipment, such as the camera of a smartphone. Of course, along with the way, we find resources, tricks and optical illusions that seem to reproduce a certain “3D effect”, and one of the most important technologies that go in that direction is virtual reality. However, there is not much you can do with a traditional photo … unless you are involved in an advanced conversion process. In the case of Google Earth, the Mountain View giant uses thousands of images obtained with aeroplanes to develop 3D models.

    The portal 3dthis.com offers 3D Face, a tool to process self-portraits, and other images in which the face of a person looks directly at the camera (3D Face delivers very strange results when the face is in profile). Once the image is loaded, 3D Face will do a preliminary detection of coordinates, which we must adjust by hand. Once we are satisfied, we activate the conversion process and take us to a new section of the tool, which has several auxiliary animations, such as sadness, surprise, anger and happiness. The final step is to publish our results, but that requires creating an account on the page.

    In addition to being able to share and comment on the final animation, another option of 3D Face (perhaps the most important) is to convert the image into an MP4 video, which in turn enables the animated GIF. The performance of 3D Face is inferior when compared to more elaborate programs, but the ease of use and the conversions without limits play in your favour.

  • “Play to Cure: Genes in Space” – A mobile game which helps cure cancer!

    “Play to Cure: Genes in Space” – A mobile game which helps cure cancer!

    Have you ever thought that a mobile phone game can help cure a deadly disease like cancer? “Play to Cure: Genes in Space” is a cool game in which you take the handles of a spaceship and drive around asteroids and space rocks to get valuable and powerful elements called Alphas. The revolutionary part is that you are actually trying to help the scientists to analyze a lot of real data. This game is jointly developed by Cancer Research UK, Amazon, Google, Facebook and Omnisoft. The game allows public to help the scientists identify patterns of genetic information of thousands of tumors through an enjoyable experience.

    ASTEROID FIELDS AS A GENETIC DATA

    This mobile game resembles a classic flight simulator: the user controls a spaceship that must cross asteroid fields and get bonus called “Alpha Elements”. The innovation lies in the development of the asteroid fields- these fields are developed based on genetic data from analyzes of more than 2000 patients with cancer.

    A DIGITAL SIMULATION FOR HUMAN ANALYSIS

    The collected data includes a cluster of information that could help to heal specific diseases. The difficulty lies in the fact that many (nearly two million data points for each patient) would take considerable time to be analyzed by professionals, while a computer analysis would not be as effective as a human eye.
    This is where this mobile game strikes: when a player makes a good run between asteroids and by harvesting a large number of the so called “Alpha” elements, it actually draws a coherent route from the chips to the genes. So each user provides a human analysis of individual patient data, as well as track treatment.

    A REVOLUTIONARY IDEA

    Available on iOS and Android, “Play to Cure: Genes in Space” is already a revolution in the sense that it uses the direct inputs from the users for fighting against cancer. If the actual results are not yet measurable, this playful approach to the analysis of the data opens up new perspectives in the relationship between medicine and new technologies.We can hope that similar kind of innovative apps will continue to be developed, which will make it possible to make faster advancements in science. “Play to Cure: Genes in Space” is truly an enjoyable way to support research against cancer.
