10 Best FPV Drone Goggles For A Terrific Flying Experience

by
Best FPV Drone Goggles

Flying using FPV drone goggles is a terrific experience. To have the best flying experience, it is important to choose the best FPV glasses, which are correct for you.

Knowing about field of view, IPD, glass optics, resolution and digital head tracking will help you pick the right drone goggles.

A number of drone manufacturers now have their own drone goggles.  DJI, Parrot, Walkera And Yuneec now manufacture their own FPV drone goggles.  This makes choosing an FPV headset very easy.

Now if you own a DJI or Yuneec drone etc, you don’t have to buy their goggles as many drone goggles from the various manufacturers will work on the latest top drones on the market.

It is important to fly using the correct drone goggles for your eyes. If you choose an incorrect fitting FPV headset, then you won’t enjoy the experience as much as you should.  Most drone goggles on the market now have many adjustable settings and are very comfortable.

In this article with videos, we show how to choose the best FPV glasses along with looking at some of the most popular FPV headsets on the market.  FPV goggles from Fat Shark, Skyzone, Epson, Oculus, Zeiss, Yuneec and Walkera along with both of the latest DJI FPV goggles.

Nearly all the FPV goggles featured in this article can be used for flying drones, watching movies and playing games.

12 Top Lidar Sensors For UAVs, Best Lidar Drones And Great Uses

by
7 Top Lidar Sensors For Drones

Lidar sensors on UAVs capture imagery which only a few years ago needed an aircraft carrying large heavy lidar sensors and a crew to accomplish.

Here, we look at 12 of the best lidar sensors for drones along with the best lidar drones.

We feature lidar sensors from manufacturers such as Velodyne, Routescene, Leddartech, Riegl, YellowScan, Leica and Geodetics.

The lidar drones include quadcopters, fixed wing drones, UAV helicopters from manufacturers such as DJI, Harris, Velos, Vulcan, OnyxStar and many more.

A lidar sensor mounted on a UAV, along with the lidar software can process images very quickly in the cloud, allowing for effective decisions to be made by stakeholders and relevant parties.

The output from these lidar drones and sensors is outstanding.  The pace of development and improvement in the lidar sensors over the past few years has been tremendous and will continue with more entrants into this sector.

Over the coming years, we are going to see most of the lidar sensor work moving from aircraft to lidar drones.

In fact, all the manufacturers of the large lidar sensors for airplanes have developed smaller lidar sensors for drones.

We start off this post with the lidar drones being used for the various sensors, followed by how lidar sensor technology works. Then, we look at the best lidar sensors for drones.  Along the way, we have some terrific lidar drone sensor videos.

Multispectral Imaging Camera Drones In Farming Yield Big Benefits

by
Multispectral imaging agriculture drones with sensors

Multispectral imaging camera sensors on agricultural drones allow the farmer to manage crops, soil, fertilizing and irrigation more effectively.

There are huge benefits both to the farmer and to the wider environment by minimizing the use of sprays, fertilizers, wastage of water and at the same time increasing the yield from crops.

Multispectral camera remote sensing imaging technology use Green, Red, Red-Edge and Near Infrared wavebands to capture both visible and invisible images of crops and vegetation.

The multispectral images integrate with specialized agriculture software which output the information into meaningful data.

This land telemetry, soil and crop data allow the  grower to monitor, plan and manage the farm more effectively saving time and money along with reducing the use of pesticides.

Calibrate The Compass On Phantom 4 Drone To Fix Flight Issues

by
How To Calibrate The Compass On DJI Phantom

Knowing how to calibrate the compass on the Phantom 4 drone is very important. Also, the compass calibration is the same for both Phantom 4 and Phantom 4 Pro.

You should calibrate the Phantom 4 compass if the DJI GO 4 app or the status indicator on the Phantom 4 prompts you to calibrate.

For example, you would calibrate the Phantom 4 compass if you are flying the quadcopter in a new area. Also, if you feel the the Phantom 4 drone is not flying correctly or is not reacting to your touch as it should, then calibrating the Phantom 4 compass may fix the issues.

This article covers the steps to calibrate the Phantom 4 compass along with information on status indicator lights and what to do if the calibration fails.

Introduction To UAV Photogrammetry And Lidar Mapping Basics

by
Using UAVs for photogrammetry and aerial LiDar mapping

UAV lidar and photogrammetry imaging applications are increasing rapidly. This is not surprising as using GPS enabled UAVs for aerial surveying is very cost effective in comparison to hiring an aircraft with photogrammetry equipment.  

Because UAVs are relatively inexpensive, organisations will have their own UAV fleet, allowing for rapid surveys over large land areas and infrastructure projects where required. 

With GPS equipped drones, digital cameras and powerful computers, surveys have an accuracy right down to 1 centimeter.

This post takes an overall look at this drone mapping technology. We also take a quick view at the sectors benefiting from using UAVs for photogrammetry and lidar mapping.  We also look at some of the best mapping drones on the market along with the compatible software.

Another closely related sector is using LiDAR sensors mounted onto drones.  It’s another growing sector and you can read further regarding drone LiDAR use here.
