How DJIs Phantom 4 RTK Delivers Reliable and Accurate Site Surveys

ActiveTrack will work down to 6ft above the ground when the aircraft is switched to P mode. 11.What are the major differences between the propellers and the Phantom 3 ones? The new Push-and-Release propellers are faster to install and more secure than the Self Tightening propellers used previously.

This is a challenge for beginner pilots as well as experienced pilots, especially when sight lines are obstructed and you are fully concentrating on filming. Both TapFly and ActiveTrack are very easy to configure in the DJI Go app. ActiveTrack sees and recognizes objects using the camera of the Phantom 4. The Phantom 4 Pro automatically recognizes subjects, follows and captures them as they move, making it easier to get complex shots. The Phantom 4 Pro can automatically identify and track bikes, vehicles, people and animals. When this mode is enabled, the Phantom 4 Pro’s current height will be recorded.

DJI has been a major innovator in the drone market with its ready-to-go Phantom series. In the unlikely event that front and downward sensors are unable to operate, the aircraft can still hover in place using the rear stereo vision system. The Phantom 4 Pro also is able to fly in complex environments at a flight speed of up to 31 miles per hour while avoiding obstacles in its path.

The small size and agile flight performance make these improvised drones very difficult to spot and destroy. Newer aircraft offer some powerful alternatives to the big Phantom series as well. Craft like the DJI Air 2S offer the same size of camera, but with a much newer sensor and software, not to mention the smaller and more agile airfame and lower price tag. No longer is the Phantom series the best if you want a 4K camera in the sky.

In daylight flying, as you won’t need to be fiddling around with the ISO, all you need to adjust is the shutter speed to affect your exposure. As the ’s lens is a fixed f/2.8 aperture, Manual mode basically consists of altering ISO and shutter speed to adjust exposure. There are several shooting modes to choose from on the Phantom 4, including most of those found on your dSLR – burst mode, time lapse, HDR and exposure bracketing. Controls are Auto or Manual, and you can control everything down to applying a custom white balance. The battery charger can charge both the controller and the drone’s battery at the same time, which is a convenient feature. The batteries on the controller and the Phantom 4 take around 90 minutes to charge.

It’s a big improvement over Follow Me, available in the Phantom 3, which would follow only the drone’s remote controller. Released in October 2013, it was the first of the Phantom 2 series to be released, and featured significant upgrades over the original Phantom. Upgrades over the original Phantom include auto-return, increased flight speed, increased flight time and controllable range, increased battery capacity, and smart phone or tablet connection capability. It later became compatible with a ground station and iOS or Android devices. It was the first DJI aircraft to be released with the “Intelligent Li-Po battery” which enabled flight times of almost 20 minutes.

The 1-inch sensor size has proven to be a very capable format in compact cameras like the Sony Cyber-shot DSC-RX100 III ($1,799.00 at DJI) . However, on the flip side, the large drone makes it easy to hand-catch the aircraft during landing procedures. And the larger remote controller makes the drone easier to fly for people with larger hands or even with gloves on. The controller is easy to grab and buttons are easy to find and press. The phantom 4, as mentioned, has a 1/2.3-inch camera sensor, the newer drones in the Phantom line come with a full 1-inch sensor.

The aperture is manually adjustable from your remote controller, from f2.8 down to f11. The 60fps recording speed in 4K video allows slow motion that is smooth, professional-quality and TV-ready. The bigger sensor takes stills to an outstanding 20MP on the Phantom 4 Pro+ V2.0, up from 12MP on earlier P4s. And the maximum burst rate doubles to 14fps from 7fps on earlier P4s.

The same photography principles still apply in the air as they do on the ground, and an aerial platform does not make a great photographer. That said, those coming from earlier Phantoms, even as recently as the non-pro version of the dji mini 2 fly more combo, are certain to notice the difference in quality. Controls are really where the DJI Phantom 4 Pro V. 2.0 starts to shine. Phantom 4 RTK lists its GSD as (H/36.5) cm/px, with H as the aircraft altitude above the target. Instead, they say accuracy depends on lighting, patterns, aircraft altitude and software used to process the imagery.

Other notable enhancements include lighter props and reduced overall takeoff weight, wireless integration with DJI Goggles, and bolstered transmission power. The Phantom 4 Pro redefines the iconic Phantom series, bringing imaging and intelligence to new heights. Its uprated camera shoots 4K/60fps at a bitrate of 100Mbps and stills up to 20-megapixels, creating dramatically better images. The FlightAutonomy system adds dual rear vision sensors and two Time of Flight range imaging cameras for a total of 5 directions of obstacle sensing with a range of up to 30m in all directions. The upgraded Lightbridge HD video transmission system offers an extended maximum transmission range of 4.3mi and also enables you to switch between 2.4GHz and 5.8GHz. It can also be used with an optional integrated monitor for even more reliable transmission.
